Plutonium Disposition Strategy

Statement,
UK Parliament 24th Sept 2025, https://questions-statements.parliament.uk/written-statements/detail/2025-01-24/hcws388

The Department for Energy Security and Net Zero will work with the Nuclear Decommissioning Authority (NDA) to immobilise the UK-owned civil separated plutonium inventory at Sellafield.

Continued, indefinite, long-term storage leaves a burden of security risks and proliferation sensitivities for future generations to manage. It is the Government’s objective to put this material beyond reach, into a form which both reduces the long-term safety and security burden during storage and ensures it is suitable for disposal in a Geological Disposal Facility (GDF). Implementing a long-term solution for plutonium is essential to dealing with the UK’s nuclear legacy and leaving the environment safer for future generations.

Following a public consultation in 2011 the government at the time formed a preliminary policy view to pursue reuse of plutonium as mixed oxide fuel (MOX) but to remain open to any alternative proposals for plutonium management.

NDA have since carried out substantial technical, deliverability and economic analysis to identify a preferred option for a long-term disposition solution, including options for immobilisation and reuse. The outcome of this work recommended immobilisation as the preferred way forward to put the material beyond reach soonest and with greatest delivery confidence.

Following further development work the NDA will select a preferred technology for immobilisation of the plutonium as a product suitable for long-term storage and subsequently disposal in a GDF. Organisations involved in the delivery of this work will include the NDA, in particular Sellafield Ltd and Nuclear Waste Services, the UK National Nuclear Laboratory and the wider supply chain.

We expect that around the end of the decade following Government approval the NDA and Sellafield will begin delivery of the major build programme of plutonium disposition infrastructure. This programme is expected to support thousands of skilled jobs during the multidecade design, construction and operational period.

While work continues on long term immobilisation, the NDA is ensuring the continued safe and secure storage of plutonium in the UK. As part of this approach, new facilities are being built at Sellafield to repack the plutonium inventory for placement in a suite of modern stores.

The death of Karen Silkwood—and the plutonium economy

The vision first created during World War II—and fostered with tens of billions of dollars of public funds—to establish nuclear power plants fueled by plutonium started to take on a nightmarish quality.

Within the next 10 years following the Indian nuclear explosion and Karen Silkwood’s death, the US Congress pulled the plug on the Liquid Metal Fast Breeder Reactor project, ending the Atomic Energy Commission’s vision of a plutonium economy, and the Supreme Court provided a little bit of justice for Karen’s parents and children, upholding a jury decision that for the first time cast aside the legal shield of the federal government protecting the nuclear industry.

Bulletin, By Robert Alvarez | November 8, 2024

On the evening of November 13, 1974—that is, 50 years ago—Karen Silkwood was driving to a meeting with a New York Times reporter and an official of the Oil, Chemical and Atomic Workers (OCAW) union. Her car flew off the road and hit a culvert on a lonely highway in western Oklahoma, killing her instantly. Karen was a union activist working as a technician at a plutonium fuel fabrication plant in Cimarron, Oklahoma owned by the Kerr-McGee Corp.

Several days before her death, Silkwood’s apartment was purposefully contaminated with highly toxic plutonium—which she had no access to—from the nuclear plant where she worked. Because of her activism, the company had put her and her roommates under constant surveillance. Documents about problems at the plant that two witnesses had seen before Silkwood’s fateful drive were missing. An independent investigation found evidence that her car was run off the road—contradicting official conclusions.

Karen became a whistleblower in large part because Kerr-McGee never bothered to tell workers that microscopic amounts of plutonium in the body can cause cancer. Karen became alarmed after dozens of workers, many fresh out of high school, had breathed in microscopic specks of plutonium and were required to undergo a risky procedure (chelation) to flush the radioactive contaminant from their bodies. It’s a procedure that can, even if successful in removing contaminants from the body, harm the kidneys.

Between 1970 and 1975, two metric tons of weapons-usable plutonium were shipped by truck from the Hanford nuclear production complex in Washington state to the Kerr-McGee plant in Oklahoma, where the plutonium was to be mixed with uranium and placed into 19,000 stainless steel fuel rods. At the time of Karen’s death, the Atomic Energy Commission found that about 40 pounds of plutonium had gone missing—enough to fuel several atomic bombs.

Since then, numerous books, articles, documentaries, and a critically acclaimed Hollywood motion picture have focused on the circumstances surrounding Silkwood’s death. My late wife and I were engaged in efforts for nearly a decade to achieve justice for her parents and children; those efforts were chronicled in some detail in Howard Kohn’s 1981 book, Who Killed Karen Silkwood? Was this an unfortunate accident, or was Karen Silkwood run off the road and killed to stop her from revealing dark secrets? After more than 40 years, the definitive answers to these questions remain unavailable.

The beginnings of the Silkwood saga. Karen Silkwood’s death heralded an end of America’s romance with the atom as a source of limitless cheap energy. There was no doubt on the part of the AEC, then the dominant force behind US energy policy, that commercial nuclear power would expand so rapidly and widely that by the end of the 20th century, the world would exhaust its supplies of uranium. If nuclear power was to thrive thereafter, according to AEC doctrine, a new generation of reactors fueled by plutonium extracted from spent nuclear fuel would have to be built. This new generation of so-called “breeder” reactors held the promise of producing vast amounts of cheap electricity while producing up to 30 percent more plutonium than they consumed. It turned out that the AEC’s nuclear power growth projection was off by an order of magnitude. Even today, world uranium supplies remain more than sufficient to fuel existing and reasonably contemplated commercial power plants.

Were it not for my wife, Kitty Tucker, and our friend, Sara Nelson, the death of Karen Silkwood would have been erased from public memory, like a sand painting blown away by the wind. I am proud to have played a supporting role, working with Karen’s parents and congressional staff, raising funds, reviewing technical documents, helping with the news media, cooking a lot of meals, and recruiting expert witnesses for the trial of a lawsuit over Silkwood’s death that would unfold in the spring of 1979.

Working with little and often no financial resources but a lot of grit, Kitty and Sara organized a national campaign that led to a congressional investigation revealing that Karen’s concerns over nuclear safety at the Kerr-McGee plant were more than justified. The congressional investigation exposed an FBI informant with a long history of spying on US citizens and revealed that enough plutonium to create several nuclear weapons was missing from the plant. These findings set the stage for a lawsuit organized on behalf of Karen’s parents and children.

The nine-week trial before a federal court jury in Oklahoma City resulted in a landmark jury decision that held Kerr-McGee liable for contaminating Silkwood and her home and awarded her estate a multimillion-dollar verdict. But the path to that verdict was long and uncertain and often disorganized and contentious, a David-and-Goliath story that ran from a near-commune of a house in a leafy portion of the District of Columbia through a variety of congressional offices and investigators and into the pages of Rolling Stone magazine. Along the way, a lot of young and idealistic lawyers and activists—led by Kitty and Sara—worked, mostly for free, to make sure Karen Silkwood’s death was not brushed under a bureaucratic rug and forgotten. I feel lucky to have been one of them.

………………………………………………………………………………………………………………………………………………………………… Kitty’s dogged research found that Silkwood was justified in being outspoken in her struggle to stop constant plutonium leaks and worker exposures at the Cimarron, Okla. Kerr-McGee plant. She and several other co-workers suffered from repeated plutonium exposures while on the job. Between 1971 and 1975, in fact, contamination reports show that at least 76 workers were exposed to plutonium at the Cimarron plant,[1] some more than once.[2] About a third of the exposed workers inhaled enough plutonium to require emergency treatment with experimental chelating drugs to help flush the radioactive metal out of the body. By comparison, during that same period, less than one percent of 3,324 employees at the Energy Department’s Rocky Flats nuclear weapons plant in Colorado[3]—which processed tens of tons of plutonium per year and became notorious for its poor plutonium-handling practices—required this extreme emergency measure.[4]

Kerr-McGee’s role in the plutonium economy. Long a leader of domestic uranium mining for US nuclear weapons, Kerr-McGee was among the first corporations to get in on the ground floor of the US government’s push to establish a plutonium fuel economy. The Atomic Energy Commission’s vision for such an energy economy was outlined in 1970 by its chairman, Glenn Seaborg, who discovered plutonium 30 years earlier. By the end of the 20th century, Seaborg estimated, an enormous expansion of nuclear power plants would have all but exhausted world uranium reserves, and new US reactors would require 1,750 tons of plutonium. This would be more than 66 times the amount of this deadly nuclear explosive in today’s worldwide nuclear weapon stockpiles.[5]

Kerr-McGee came in with a low bid to design and operate one of two of the first privately owned plutonium fuel plants that would handle tons of this fissile material. The Kerr-McGee facility was engineered to extract plutonium nitrate liquid from spent nuclear fuel generated at Hanford’s material production reactor and sent by guarded trucks to the Cimarron, Oklahoma plant. Once there it underwent 14 complex processing steps. The first blended liquid plutonium with uranium. The blended material was then sent to a furnace where it was dried into a powdered oxide. The powder was then heated, compressed, and ground into pellets. The pellets were then placed into stainless-steel rods, after which the ends of the rods were welded shut. All told, some 19,000 of these fuel rods were shipped back to Hanford, where they were used in experiments at the Fast Flux Test Facility (FFTF) and another research reactor. These reactor experiments were aimed at the development of the first large-scale liquid metal fast breeder reactor (LMFBR), to be built along the Clinch River near the government’s Oak Ridge nuclear site in eastern Tennessee.

It turned out that Kerr-McGee cut corners at the expense of the health and safety of its workers from the outset of its operation. The company squeezed in as much equipment as possible into its facility, a space about half the size of a typical high-school gymnasium, leading to spills that were often difficult to clean up. Miles of pipes in the cramped workplace were so close together and poorly routed that they would not fully drain, creating excessive radiation levels[6] in the plant.

Cramped piping also made it difficult to account for the plutonium carried through them, which was classified by the government as a Category I strategic special nuclear material—that is, material that “in specified forms and quantities, can be used to construct an improvised nuclear device capable of producing a nuclear explosion.”[7]

Gloveboxes—the laboratory workstations with gloves in their transparent walls, so workers could manipulate plutonium without coming into direct contact with it—became a major source of contamination because the type installed by Kerr-McGee used plastic seals that US weapons plants had long known could degrade and leak. Also, there were few contained connections between gloveboxes, so workers had to transfer radioactive materials in the open, creating greater risks of contamination. The ventilation systems did not permit rooms in the facility to be isolated from one another to minimize the spread of contamination when it occurred. Even the plant’s radiation air filters were configured in a way that made them difficult to replace.[8]

As substandard facilities led to contamination, Kerr-McGee failed to inform workers that plutonium can cause cancer. Managers often claimed that it was harmless. “There has been no lung cancer caused by plutonium exposure,” William Utnage, the plant designer, told employees. “From human experience to date, we have nothing to worry about.” Based on numerous animal studies, the Atomic Energy Commission considered plutonium to be a potent carcinogen.

Turnover was high at the Kerr-McGee Cimarron plutonium plant, with an average of 90 people out of the plant’s total workforce of 150 quitting each year.[9] AEC inspections found that the company could not keep accurate track of radiation doses, making it difficult if not impossible to know the frequency and severity of exposures. Given the need to constantly replace three out of five workers every year, many people were hired fresh out of high school, provided minimal training, and sent on the line to operate a high-hazard nuclear facility.

After being repeatedly exposed to plutonium at the plant that required often painful scrubbing of her skin, Karen Silkwood began documenting dangerous practices at the plant, including the doctoring of X-rays of fuel rod welds by a technician who used a felt-tip pen to hide defects shown in the X-rays.

Days before she died in the car crash, plutonium contamination was found in the home that Silkwood shared with her boyfriend, Drew Stephens, and roommate, Sheri Ellis. The highest concentrations were in lunch meat in her refrigerator and on the toilet seat. Karen, Drew, and Sheri were soon flown to Los Alamos Laboratory, where it was determined that Karen had sustained a significant dose of plutonium in her lungs. Subsequent laboratory analyses concluded that the plutonium in her home came from a batch at the plant to which she did not have access. These revelations all happened within the few days before her fatal drive that night of November 13, 1974.

Congress takes interest. In a way. Just five months before Karen Silkwood’s death, India conducted its first nuclear weapon test; it involved a bomb fueled with plutonium extracted from spent fuel produced by Canadian nuclear reactors. Growing concern in the US Congress about the thought of plutonium circulating in world commerce focused attention on the missing plutonium from the Kerr-McGee plant where Silkwood had worked.  Although the amount of the unaccounted-for material was less than a tenth of a percent of the 2.2 tons handled at the plant, it was enough to fuel as many as four nuclear weapons. The Silkwood case also led to greater congressional scrutiny of how the government accounted for and safeguarded its stocks of nuclear materials.

…………………..In the spring of 1975, with our infant daughter Amber in a stroller, my wife Kitty and Sara Nelson met with Tony Mazzochi, legislative director of the Oil Chemical and Atomic Workers (OCAW), and his union colleague Steve Wodka. Both had worked closely with Karen Silkwood in support of efforts to prevent Kerr-McGee from decertifying the union and to strengthen worker safety. The night Silkwood died, Wodka was in a hotel room waiting with New York Times reporter David Burnham for Karen to show up. Shortly after that meeting, Kitty and Sara were recruiting a legal team, led by Daniel Sheehan, to take this case into federal court, on behalf of Karen’s parents.

……….. As I began my work at EPC, one of my first tasks was to serve as a representative on Capitol Hill for Bill and Meryl Silkwood, Karen’s parents. Deeply upset by the suspicious death of their daughter, they approached us in the late fall of 1975 seeking help………………………….. Among the initial appointments I set up for them on Capitol Hill was one in the high-security offices of the Joint Committee on Atomic Energy on a top floor of the US Capitol, accessed by a special elevator. After we went over numerous safety concerns about the Kerr-McGee plant, we were given a polite but frosty response by the committee’s staff director, who curtly advised Bill to go back home and write a letter to his congressman.

The response came as no surprise. Kerr-McGee founder Robert S. Kerr held sway over atomic energy matters as a US senator from the late 1940s until he died in 1963. In 1948, the year Robert Kerr was elected to the U.S. Senate, Kerr-McGee became the first oil company to take advantage of the uranium boom, opening mines on the Navajo reservation to take advantage of the US government’s lucrative price guarantees. By 1954, the company dominated the US uranium market.

By the summer of 1975, Kitty and Sara had collected 8,500 signatures from NOW members and others petitioning Sen. Abraham Ribikoff, chair of the US Senate Committee on Governmental Affairs, to launch an investigation into the circumstances surrounding Karen Silkwood’s death.

On the anniversary of Silkwood’s death—November 13, 1975—during a congressional recess, several NOW members pressed Ribikoff in his home state of Connecticut. Six days later, Ribikoff and his Senate colleague Lee Metcalf of Montana met with a large delegation including Karen’s parents, Kitty, Sara, newly elected NOW President Eli Smeal, religious advocates, and me. Also joining the meeting were Peter Stockton, on loan from Michigan Congressman John Dingell’s staff, and Win Turner. Ribicoff quickly agreed to an investigation and passed the baton to Senator Metcalf……………………………………

In addition to raising serious questions about the investigation of the accident that killed Silkwood, Newman and Stockton revealed that 40 pounds of plutonium was missing and unaccounted for at the Kerr McGee plant. The AEC failed to successfully black out this discrepancy from the document Newman obtained under the Freedom of Information Act. Twenty years later, after the Cimarron plant was dismantled, only 20.2 pounds were recovered from its pipes, leaving enough missing plutonium to fuel two Nagasaki-type atomic bombs.

Turner and Stockton now had a congressional green light to press the Energy Research and Development Administration, the Nuclear Regulatory Commission and especially the FBI for their investigative documents covering the Silkwood case…………………………

………………………….. By this time, pressures were mounting for Turner and Stockton to back off investigating Silkwood’s death. Republican staff on the Governmental Affairs Committee blocked travel funds needed to interview key officials. Turner had to prevail on a less-than-enthusiastic Senator Metcalf to intervene. Eventually, Stockton prevailed on Dingell to pay for his trip to Nashville to try to gain greater cooperation from Srouji.

Shortly thereafter, Metcalf dropped the investigation into Silkwood’s death,[10] but Dingell picked up the ball, thanks in large part to his trust in Stockton, and held two public hearings that showed the disturbing lack of safety working at the plant. 

………………………………………..Under the threat of being held in contempt of Congress, Srouji turned over documents she claimed to have obtained from the FBI. The documents indicated that the FBI’s investigation of events surrounding Silkwood’s death was superficial. Most conspicuous by its absence was any documented effort by Olson and the FBI to address the AEC’s concern that Kerr McGee could not account for about 40 pounds of plutonium.[12]

The Silkwood lawsuit begins. By the fall of 1976, congressional investigations had run their course, leaving Karen’s parents only with the option of going to court. ………………………………………..

The complaint had three basic components: Kerr McGee was liable under state law for the contamination of Karen Silkwood in her home; Kerr McGee violated Silkwood’s civil rights to travel on the highway; and finally Kerr McGee conspired to violate Silkwood’s civil rights. It turned out that the contamination of Karen’s home with plutonium from the plant became the anchor for the lawsuit………………………………………………………………………………………………………..

 Bill Paul, Kerr McGee’s lead attorney and former president of the Oklahoma Bar Association, seemed determined to stop the case from going to trial by proving we were “outside agitators” in a conspiracy, supposedly run by Ralph Nader and the Communist Party, to stop nuclear power in the United States………………………………………………………  Through the efforts of investigative reporter Howard Kohn and his wife and assistant Diana, Rolling Stone made the Silkwood case a major investigative focus and played an important role in raising funds for the lawsuit.[15]

………………………………………………………………………….As trial approached, Danny and his investigators tried to shine a light on efforts by Kerr-McGee to spy and intimidate Silkwood, possibly to the point of running her off the road, and the FBI’s efforts to conceal Kerr McGee’s wrongdoings. Even though Danny and his colleagues found a considerable amount of evidence to back these claims, the federal judge on the case, Frank Thies, ruled that conspiracies to violate Karen Silkwood’s civil rights were not covered by the law. This left the legal liability against Kerr McGee for contaminating Silkwood in her home as the only issue to be argued in court.

………………………………………………………………………..Kitty and I moved out to Oklahoma City and watched the 47-day trial unfold as Gerry Spence masterfully took apart Kerr-McGee’s defense. Bill Paul, Kerr’s McGee’s lead attorney, had not faced a seasoned court roombrawler like Gerry Spence before. From the outset, Spence, with his large-brimmed cowboy hat sitting on the table and cattle rancher demeanor, and his co-counsel, the much shorter, frizzy-haired Arthur Angel, created a “David vs Goliath” atmosphere. Ranged against them were a half dozen defense attorneys in three-piece suits who immediately became known as the “men in grey.”

After 43 witnesses gave testimony, the case went to the jury, and on May 18, 1979, the jury rendered its verdict. Bill and Merle Silkwood sat beside Kitty and our 4-year-old daughter, Amber. Dean McGee, the president and co-founder of the Kerr-McGee Corp., and leaders of the Oklahoma State Legislature were also present to hear the jury find Kerr McGee liable for $505,000 in actual damages and $10 million in punitive damages. On January 11, 1984, the US Supreme Court upheld the jury’s verdict, but allowed Kerr-McGee to contest the punitive damages in another trial. Not wanting to go through another lengthy trial Karn’s family agreed to a $1.38 million setlement.

The end of the plutonium economy. A highly eventful year followed Karen’s death; those events would impact the future of nuclear energy around the world.

In May 1974, India shocked the world by detonating a nuclear weapon underground in the remote desert region of Rajasthan. Called the “Smiling Buddha,” the weapon was fueled by plutonium produced in a reactor provided by Canada that used heavy water supplied by the United States from the Savannah River Plant, a nuclear weapons material production facility in South Carolina. India extracted the plutonium from spent reactor fuel at a reprocessing plant built with the assistance of the United States and France. The Indian weapons experts who designed Smiling Buddha were trained by the Soviet Union.

India declared its weapon test a “peaceful nuclear explosion.” Between 1961 and 1975, the United States and the Soviet Union set off 35 and 124 “peaceful” nuclear detonations, respectively, in a quest to dig channels, recover minerals, excavate tunnels for highways, store oil and gas, and build dams. Undeterred by the radiological problems peaceful nuclear explosions would cause, the United States actively promoted their use, which made sure that other countries would follow, as an integral part of the “peaceful” uses of nuclear power allowed under the 1970 Nuclear Non-Proliferation Treaty.

In 1976, then-President Gerald Ford responded, suspending reprocessing of spent nuclear fuel to recover plutonium in the United States. The next year, President Jimmy Carter converted the suspension into a ban, issuing a strong international policy statement against establishing plutonium as fuel in global commerce. As the US government continued to refuse to support reprocessing of nuclear fuel, US utilities with nuclear power plants opted to support underground disposal of spent fuel.

The vision first created during World War II—and fostered with tens of billions of dollars of public funds—to establish nuclear power plants fueled by plutonium started to take on a nightmarish quality. Within the next 10 years following the Indian nuclear explosion and Karen Silkwood’s death, the US Congress pulled the plug on the Liquid Metal Fast Breeder Reactor project, ending the Atomic Energy Commission’s vision of a plutonium economy, and the Supreme Court provided a little bit of justice for Karen’s parents and children, upholding a jury decision that for the first time cast aside the legal shield of the federal government protecting the nuclear industry.

Eventually, Kerr-McGee’s destructive practices caught up with it. In April 2014, after fraudulently trying to avoid paying for the cleanup of the massive environmental damage it had wrought throughout the United States, Kerr-McGee entered into a $5.5 billion settlement with the US Justice Department. Kerr-McGee is now a bankrupt legacy of the atomic age, a relic of a plutonium economy that never came to be in the United States.

Isotopic signature of plutonium accumulated in cryoconite on glaciers worldwide

Science Direct, Volume 951, 15 November 2024,

Edyta Łokas a, Giovanni Baccolo b, Anna Cwanek a, Jakub Buda c, Katarzyna Kołtonik a, Nozomu Takeuchi d, Przemysław Wachniew e, Caroline Clason f, Krzysztof Zawierucha c, Dylan Bodhi Beard g, Roberto Ambrosini h, Francesca Pittino i, Andrea Franzetti i, Philip N. Owens j, Massimiliano Nastasi kl, Monica Sisti i, Biagio Di Mauro m

Highlights

  • •Cryoconite samples show larger deposition of 239+240Pu, but not of 238Pu, in the Northern than in the Southern Hemisphere
  • •Isotopic signatures of Pu in cryoconite show that besides the global fallout the regional contributions may be significant
  • •First evidence of 238Pu contamination from the crash of Interplanetary Station “Mars’96”

Abstract

Glaciers are recognized as repositories for atmospheric pollutants, however, due to climate change and enhanced melting rates, they are rapidly transitioning from being repositories to secondary sources of such apollutants. Artificial radionuclides are one of the pollutants found on glaciers that efficiently accumulate onto glacier surfaces within cryoconite deposits; a dark, often biogenic sediment. This work provides information about the accumulation, distribution and sources of plutonium (Pu) isotopes in cryoconite samples from glaciers worldwide.

 Plutonium is an artificial radionuclide spread into the environment in the last decades as a consequence of nuclear test explosions, accidents and nuclear fuel re-processing. Samples collected from 49 glaciers across nine regions of Earth are considered. Activity concentrations of plutonium in cryoconite are orders of magnitude higher than in other environmental matrices typically used for environmental monitoring (e.g. lichens, mosses, soils and sediments), particularly in the Northern Hemisphere. 

 Isotopic ratios indicate that plutonium contamination of cryoconite is dominated by the global signal of stratospheric fallout related to atmospheric nuclear tests. However, specific glaciers in Svalbard reveal a signature compatible with a contribution from the re-entry of the SNAP-9A satellite in 1964, which was equipped with a 238Pu radioisotope thermoelectric generator. Similarly, an excess of 238Pu is observed in cryoconite from the Exploradores Glacier (Chile). This could be associated with the November 1996 crash of the automatic Interplanetary Station “Mars ’96” which was carrying a 238Pu thermoelectric generator. This is the first time ever that an isotopic evidence for this event is reported. These findings highlight the role that cryoconite can play in reconstructing the radioactive contamination history of different glaciated regions of the Earth.

Introduction

Atmospherically derived radioactivity is the component of environmental radioactivity that is deposited on the Earth’s surface through wet and dry deposition from the atmosphere. The deposited radionuclides are also named fallout radionuclides (FRNs). Some FRNs have a natural origin, such as cosmogenic 7Be and 14C, or are decay products of primordial isotopes. This is the case for 210Pb, which derives from 238U.

However, most FRNs are artificial and occur globally as a result of atmospheric nuclear tests and unintentional nuclear accidents (UNSCEAR, 1982, UNSCEAR, 2000). A key requirement when dealing with environmental radioactivity is the assessment of contamination levels, including the reconstruction of contamination histories, the identification of transport pathways, and of the fate of the radioactivity released into the diverse environmental compartments (Engelbrecht and Schwaiger, 2008).

Glaciers are especially important for studying atmospheric fallout history (Jaworowski et al., 1978). First, glaciers consist of deposits of atmospheric precipitation and intrinsically accumulate fallout species, including FRNs. Under specific conditions (i.e. no melting, low horizontal ice flow), by studying the stratigraphy of ice and snow layers, it becomes possible to reconstruct the depositional history of FRNs (Gabrieli et al., 2011; Olivier et al., 2004). In addition to glacier ice, attention has recently turned to another environmental matrix typical of glaciated landscapes which accumulates radioactivity; cryoconite that is a type of sediment found on the surface of glaciers worldwide (Cook et al., 2016). …………………………………..

Plutonium (Pu) is a toxic, radioactive and predominately anthropogenic element produced through neutron irradiation of uranium in nuclear reactors and during nuclear weapon detonations (Zhong et al., 2019). The most significant releases of plutonium in the Northern Hemisphere were associated with global fallout (GF) resulting from atmospheric nuclear weapon tests carried out between 1945 and 1980, with a peak in the 1960s (UNSCEAR, 1982, UNSCEAR, 2000). 

Other important sources are related to catastrophic events such as the 1978 crash of the Cosmos-954 satellite, which had a nuclear reactor on board (Krey et al., 1979; Tracy et al., 1984), as well as the Chernobyl nuclear power plant disaster in 1986 (UNSCEAR, 2010) and the Fukushima Daiichi accident in 2011 (Povinec et al., 2013a; Povinec et al., 2013b).  Moreover, from 1964 to 1980, China conducted atmospheric nuclear testing at the Lop Nor test site in north-western Chi

The Northern Hemisphere has received two-thirds of global plutonium deposition (Clark et al., 2019). Fig. 1 illustrates the most significant atmospheric nuclear testing and accident sites in the Northern and Southern Hemispheres, including those near the Equator. 

The tests conducted in the Northern Hemisphere have received significant interest but much less is known regarding the deposition that took place in the Southern Hemisphere. The United Kingdom (UK) was at the forefront of the atmospheric nuclear testing program in the Southern Hemisphere between 1952 and 1957 in Australian territory (Johansen et al., 2019), while France conducted extensive open-air nuclear testing in French Polynesia in the South Pacific Ocean from 1966 to 1974 (Bouisset et al., 2021). The UK tests resulted in a substantial amount of regional fallout (i.e., tropospheric fallout), compared to the higher-yield French tests, which contributed to the stratospheric fallout.

In 1964, the Transit 5BN3 satellite carrying a SNAP 9A radioisotope thermoelectric generator, launched by the United States of America (USA), failed to achieve orbit. The satellite burned up when descending into the upper atmosphere over Madagascar. The 238Pu load (1 kg) was dispersed worldwide and was detected globally in the environment, even in remote areas. Most of the fallout of 238Pu from this satellite occurred in the Southern Hemisphere (Hardy et al., 1972, Hardy et al., 1973). 

Another important event, although not well-documented, was reported by the International Atomic Energy Agency (Radiation and Safety, 2001) in their inventory of accidents and losses at sea involving radioactive material. According to the report, it involved the atmospheric re-entry of the automatic Interplanetary Station “Mars ’96”, which was launched on November 16th, 1996. The station fell off the coast of Chile near the border with Bolivia and has not been located to date.

Plutonium isotope deposition after weapons testing can be local, regional and global, depending on detonation height, yield and meteorological conditions ………………….

This study, for the first time, presents a comprehensive global analysis of the variation in activity concentrations of 238Pu and 239+240Pu, along with activity (238Pu/239+240Pu) and atomic (240Pu/239Pu) ratios, observed in cryoconite on glaciers from both hemispheres. 

…………………………….Conclusions

This study provides new insights into the provenance of Pu isotopes (238Pu, 239Pu, 240Pu) in glaciers based on cryoconite samples collected from nine glaciated regions of six continents. The 239+240Pu activity concentrations are significantly higher in the Northern Hemisphere than in the Southern Hemisphere, which reflects the uneven deposition of global fallout between hemispheres. Within the Northern Hemisphere the highest concentrations occur in Scandinavia and the European Alps…………………………………………….. more https://www.sciencedirect.com/science/article/abs/pii/S0048969724055062

Plutonium just had a bad day in court

In a major decision whose consequences are still being assessed, a federal judge declared that plutonium pit production — one ingredient in the U.S. government’s $1.5 trillion nuclear weapons expansion — has to be performed in accordance with the nation’s strongest environmental law

SEARCHLIGHT NEW MEXICO, by Alicia Inez Guzmán, October 17, 2024

Most Americans don’t seem aware of it, but the United States is plunging into a new nuclear arms race. At the same time that China is ramping up its arsenal of nuclear weapons, Russia has become increasingly bellicose. After a long period of relative dormancy, the U.S. has embarked on its own monumental project to modernize everything in its arsenal — from bomb triggers to warheads to missile systems — at a cost, altogether, of at least $1.5 trillion.

Los Alamos National Laboratory plays a vital role as one of two sites set to manufacture plutonium “pits,” the main explosive element in every thermonuclear warhead. But as a recent court ruling makes clear, the rush to revive weapons production has pushed environmental considerations — from nuclear waste and increases in vehicular traffic to contamination of local waterways, air and vegetation — to the wayside. 

That just changed dramatically. On Sept. 30, United States District Judge Mary Geiger Lewis of South Carolina ruled that the federal government violated the National Environmental Policy Act — the “Magna Carta” of federal environmental law — when it formulated and began to proceed with plans to produce plutonium pits at LANL and the Savannah River Site, in Aiken, South Carolina. 

“[T]he Court is unconvinced Defendants took a hard look at the combined effects of environmental impacts of their two-site strategy,” Lewis wrote of the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA), which together oversee America’s nuclear weapons stockpile.

The ruling was momentous for the anti-nuclear community. But it was also mystifying, because Judge Lewis didn’t provide a roadmap for how to move forward with this extraordinarily complicated policy dispute. Rather than bringing pit production to a halt — which plaintiffs argued for in their original complaint, filed in 2021 — the judge instead ordered the parties to reach some sort of “middle ground” among themselves and submit a joint proposal by Oct. 25. What that will consist of is anybody’s guess. The judge was clear on one point, though — she’ll be keeping a close eye on the matter by maintaining jurisdiction over the case. Injunctive relief, she added, could still be in the cards. 

NEPA’s rules require that agencies take a “hard look” at potential environmental impacts. NEPA does not, however, dictate what decision should be made once those impacts are identified. 

Previous impact statements have spelled out a vast array of potential hazards for nuclear facilities. These have included an “inadvertent criticality event,” which happens when nuclear material produces a chain reaction and a pulse of potentially fatal radioactivity. Another risk is fire igniting inside a glovebox — the sealed enclosure where radioactive materials like plutonium are handled — and then resisting suppression, leading to widespread contamination. Other possibilities: a natural gas explosion at vulnerable nuclear sites or a wildfire on LANL’s sprawling campus, which is bounded on all sides by the towns of Los Alamos and White Rock, the Pueblo of San Ildefonso, the Santa Fe National Forest and Bandelier National Monument.

“Perhaps more significantly,” Judge Lewis stated, those impact statements “provide a springboard for public comment,” a kind of mechanism for citizens to express criticism and concern and, in some cases, identify a project’s blindspots — risks to people and places that have not been properly taken into account. 

An announcement from the DOE the following day was telling, if not defiant: The first plutonium pit manufactured as part of this modernization program was ready to be deployed into the stockpile. That pit — made at LANL but the product of multiple facilities across the nation’s nuclear weapons complex — is intended for a new warhead, which will be strapped into a new intercontinental ballistic missile called the Sentinel. The Sentinel program, at $140 billion, is one of the costliest in the history of the U.S. Air Force……………………………………………………………………….

Now, almost 40 years later, the court found that the agencies charged with reviving the nuclear weapons complex have not properly evaluated the perils that could come with turning out plutonium pits at two different sites, thousands of miles apart. For the plaintiffs in this case — which include Nuclear Watch New Mexico, Savannah River Site Watch, Tri-Valley Communities Against a Radioactive Environment and the Gullah/Geechee Sea Island Coalition — Lewis’s decision to intervene is a milestone.

“We’ve had a pretty significant victory here on the environmental front,” said Tom Clements, the director of Savannah River Site Watch. “Nonprofit public interest groups are able to hold the U.S. Department of Energy accountable.” 

………………………………………………………………………………………………….. For LANL, which sits on the kind of forested land typical of the Pajarito Plateau, wildfire is a major risk. …………………………………………………..

A “parade of horribles”

The array of sites that play some role in this latest phase of pit production goes well beyond LANL and SRS, and includes existing facilities in Amarillo, Texas; Kansas City, Missouri; and Livermore, California. Hypothetically, if the feds ever produce the kind of environmental impact statement plaintiffs demand, it could potentially cover this entire constellation, requiring public hearings at each location and in Washington, D.C………………………………………… more https://searchlightnm.org/federal-judge-ruling-plutonium-pits-environmental-impact/?utm_source=Searchlight+New+Mexico&utm_campaign=ae33d0dc0a-10%2F15%2F2024+%E2%80%93+Plutonium&utm_medium=email&utm_term=0_8e05fb0467-ae33d0dc0a-395610620&mc_cid=ae33d0dc0a&mc_eid=a70296a261

The Energy Department just made one plutonium pit. Making more is uncertain

Bulletin, By Dylan Spaulding | October 10, 2024

Two conflicting developments arose this month in US efforts to produce new plutonium pits for its nuclear weapons: The National Nuclear Security Administration (NNSA) announced it had produced a warhead-ready pit—the explosive core of a nuclear weapon—for the first time in decades, and a federal court ruled that NNSA will be required to consider the cumulative environmental and health impacts of its pit production program.

Overshadowing these events is a vigorous debate over the necessity for new pits at all. Previous analyses have found that plutonium pits have viable lifespans well beyond the expected service life of the current stockpile, whereas production of pits for new weapons is part of a sweeping US nuclear modernization that raises concern over the future of arms control and any possibility for stockpile reductions at a time of deteriorating international relations.

The two most recent developments illustrate a critical tension in the US nuclear weapons program: New pit production demonstrates a doubling down of US reliance on nuclear weapons for the 21st century. The failure to adhere to environmental policy in doing so highlights the unwitting cost that US citizens may bear for this policy choice—as they have repeatedly in the past………………………………………………………………………………………………………………………………………………………………….

…….Production challenges. Despite any fanfare, demonstrating the ability to certify one plutonium pit doesn’t guarantee smooth sailing toward Los Alamos’s mandated production goals.

The Los Alamos’ Plutonium Facility at Technical Area 55 (PF-4) is conducting the dangerous and difficult work of pit production while also undergoing construction and modernization, with work happening round-the-clock—several other plutonium-related missions are pursued under the same roof. The facility has been criticized for deficiencies in personal safety and safety-related engineering, including recent glovebox fires, floods, worker exposure to plutonium and beryllium, and violations of criticality safety rules. The likelihood of such incidents increases as a result of fast-paced work in close-quarters with a mostly new  workforce. In 2013, the PF-4 facility was shut down for three years following a severe criticality safety violation; a repeat could prove fatal, literally and figuratively.

…………………………………………… Regardless of Los Alamos’ success, the congressionally mandated quota of 80 pits per year remains impossible to meet by NNSA’s own admission. This number relies on completion and commissioning of a second production facility at the Savannah River Site in South Carolina, which won’t be operational until the mid-2030s at the earliest.

Just as the future rate of plutonium pit production is uncertain, the missile these pits are intended for—the new Sentinel intercontinental ballistic missile—is also not likely to be completed on schedule. The troubled Sentinel project remains vastly over budget and behind schedule, putting its future at risk and making coordination of the warhead and missile difficult to foresee. Problems or changes in scope for either program will affect the other.

A federal court ruling.  Coinciding with NNSA’s announcement of the first diamond-stamped pit, a US District Court ruled that the Energy Department and the NNSA violated the National Environmental Policy Act (NEPA) by failing to properly consider alternatives before proceeding with pit production, requiring the agency to conduct a programmatic environmental impact assessment.

This was a victory for transparency and the community groups—among them, Savannah River Site Watch, Nuclear Watch New Mexico, Tri-Valley Communities Against a Radioactive Environment (CAREs), and the Gullah/Geechee Sea Island Coalition—who, for years, have been asking for such an assessment.

Reestablishing pit production on the scale now contemplated is potentially the biggest investment in the nuclear weapons complex since the Manhattan Project. With it comes hiring and training of thousands of new employees, increased transportation between sites, new construction, safely handing radioactive material, and the generation of new nuclear waste. The cumulative nature of these activities, occurring across many Energy Department’s sites, demands that the impacts of pit production be considered holistically in the form of a programmatic environmental impact assessment.

The environmental impact statements issued by the national laboratories offer perhaps the best public-facing analyses of whether their plans comply with standards for protection of public safety and the environment, including the likelihood of specific scenarios and associated risk of public exposure to hazards such as chemicals or radiation. Still, the NNSA has—until now—resisted issuing such a programmatic statement.

The agency clearly recognizes that pit production involves much of the US nuclear weapons complex. The press release announcing the first diamond-stamped pit thanked workers in Kansas City, Lawrence Livermore National Labs, Los Alamos, and the Pantex plant in Texas. But the NNSA has so far relied on a series of addenda and supplements to a 2008 environmental impact statement for work at Los Alamos and considers Savannah River separately. These assessments largely ignore the cross-complex collaboration required and the subsequent risks, including impacts on the potentially overburdened Waste Isolation Pilot Plant in New Mexico that must absorb the prolific—and complex—waste stream from the pit production process.

The court ruling—which holds that the Energy Department and the NNSA did not follow environmental requirements in pursuing two production sites—will require the NNSA to conduct a new review, bringing renewed public scrutiny and allowing a new opportunity for input from concerned opponents.

An unclear horizon. A programmatic environmental impact statement can take years before it’s finalized. The judge in the case declined to halt construction at NNSA’s second pit production site at Savannah River while the new assessment is being carried out, and the two parties have until October 21st to seek an agreement.  It’s likely that the NNSA will argue that stopping pit-production work would be too expensive, too disruptive, and too damaging to national security to consider. It remains unclear what the potential consequences could be if the NNSA decides to challenge the ruling.

While work at Los Alamos is likely to continue amid a programmatic assessment, design choices are still underway at the Savannah River Site, where the NNSA is attempting to retrofit the troubled former mixed oxide (MOX) fuel fabrication plant which never reached productivity despite more than $7 billion of investment. This site is years away from being active and will require extensive transformation that may cost as much as $25 billion. Given this enormous investment, a programmatic environmental impact statement can ensure that this transformation better addresses the actual hazards and better protects communities, workers, and the environment.

Reestablishing pit production in the United States is a massive undertaking. It involves resurrecting a lost capacity that requires complicated engineering, construction, and extremely hazardous work processes that will be carried out by a largely new work force with little to no prior experience. NNSA and its contractors must manage safety risks across multiple sites where new hazardous waste will be generated in communities that don’t want it and where the Energy Department has a poor historic track record of environmental stewardship.

Congress and the Biden administration should eliminate the mandated 80 pit per year requirement while the NNSA conducts a new, thorough environmental assessment that would go a long way toward promoting increased safety and public protection—a challenge that the NNSA and the labs should take seriously.  https://thebulletin.org/2024/10/the-energy-department-just-made-one-plutonium-pit-making-more-is-uncertain/

Plutonium vs Democracy: A Necessary Debate

by Gordon Edwards and Susan O’Donnell submitted to the CNSC on September 30 2024

www.ccnr.org/CCNR_CNSC_Plutonium_Paper_Sept_30_2024.pdf

The following appeal was inserted into the document:

An Appeal for Public Consultation

There is a growing pressure on the government of Canada to allow the civilian use of plutonium as a commercial reactor fuel. Such a move requires extracting plutonium from used nuclear fuel, thereby making it accessible. Once accessible, plutonium can be used as a nuclear fuel or as a nuclear explosive. Even a crude explosive device using plutonium is capable of causing enormous destruction and killing thousands.

The security measures needed to safeguard society from the threat of nuclear terrorism when plutonium becomes an article of commerce are so severe that our democratic way of life will be seriously threatened. Enforced secrecy, intrusive surveillance, and privately maintained security forces equipped with military-style weapons, are not what Canadians have come to expect from their energy suppliers.

In the last two decades, Canada has seen the wisdom of eliminating weapons-usable uranium entirely from civilian use, thereby obviating the need for extreme security measures otherwise needed to keep that material out of the hands of criminals and terrorists. In the same way, keeping plutonium out of circulation is the best way to prevent the further growth of a powerful nuclear security regime that is becoming increasingly militarized, with access to prohibited weapons under Bill C-21.

We urge CNSC to advise Parliament that there is a need in Canada for a broad public consultation or debate on the social desirability of moving toward the civilian use of plutonium in Canada or choosing to avoid that option altogether. As in the case with highly enriched uranium, we believe that there is no demonstrable need for plutonium with or without an expanded nuclear industry. Given the stakes, it is up to the people of Canada to decide the issue by democratic means. That requires a mechanism of consultation that goes far beyond public hearings.

Rumina Velshi, a past president of CNSC, has said ““Reprocessing is going to be a huge, huge deal for this country. We need to be clear: If this is not an area that this country is interested in pursuing, put a stop to it. And if there is a possibility, then let’s at least start that conversation”

As an Agency whose legal mandate is to serve the public interest rather than the interests of the industry, we urge the CNSC to speak out publicly on this important matter so that Canadians are not blindly led into a future that they may live to regret.

Japan and 11 other countries call for early start of fissile material ban talks

New York –  https://www.japantimes.co.jp/news/2024/09/24/japan/politics/kishida-nuke-material-ban-treaty/
Japan and 11 other countries on Monday agreed to work together to launch negotiations immediately on a proposed treaty banning the production of fissile materials, including highly enriched uranium and plutonium, for nuclear weapons.

A Fissile Material Cut-off Treaty will significantly contribute to nuclear disarmament and nonproliferation, high-level representatives from the 12 countries, including Prime Minister Fumio Kishida, said in a joint statement after a meeting in New York.

“A nondiscriminatory, multilateral and effectively verifiable treaty banning the production of fissile material for nuclear weapons and other nuclear explosive devices would represent a significant practical contribution to nuclear disarmament and nonproliferation efforts,” the statement said.

“The participants confirmed that they would work closely together…for the immediate commencement of negotiations on an FMCT,” the statement said. The 12 countries included three nuclear powers — the United States, Britain and France.

Kishida told the meeting that a strong political will is needed to start FMCT negotiations. Creating a momentum for an early start of the negotiations will help to maintain and strengthen the Nuclear Non-Proliferation Treaty regime, he said.

He also said Japan will send hibakusha atomic bomb victims abroad to promote the understanding of the reality of exposure to nuclear weapons. Next year marks 80 years since the U.S. atomic bombing of Hiroshima and Nagasaki.

How to Make a ‘War Reserve’ Nuclear Bomb

Earlier this year, at the annual Nuclear Deterrence Summit in Washington, D.C., there was a palpable sense of excitement at the return to Cold War strategies of shoring up our nuclear arsenal. Today, with what some call the two-peer problem—Russia and China—and the specter of nuclear-armed rogue nations and terrorists, the NSE is racing against what-if targets. The language is aggressive. Opposition is largely mute. Congress has opened the tap. The NSE is hiring, training, building, and spending billions a year.

The dark art of crafting nuclear ‘pits’ was almost lost. Now it’s ramped up into a multibillion dollar industry.

The Progressive Magazine, by Jim Carrier , September 5, 2024

Sometime in the next few months a technician at Los Alamos National Laboratory, using an arc welder, will seal together two half-domes of plutonium, creating a “pit,” a seven-pound ball the size of a grapefruit, which, if tucked into America’s newest nuclear warhead and triggered above Times Square, would destroy most of Manhattan and kill more than 1.2 million people.

The bomb is part of a $1.7 trillion plan to rebuild the U.S. nuclear arsenal. The new pit, and hundreds like it, are being made for the W87-1, a new warhead designed to sit atop the Sentinel, a new intercontinental ballistic missile design that will replace all 400 Minuteman III missiles that have been on alert in silos across the Upper Midwest for the last five decades.

Not since the Manhattan Project, the crash program during World War II to invent the atomic bomb, has so much money and urgent energy been spent by the United States to create a weapon of mass destruction. In a paradox of nuclear madness, production of the W87-1—each one with a yield of around 400 kilotons, twenty times larger than the bombs that destroyed Hiroshima and Nagasaki—is breathing life into the U.S. Nuclear Security Enterprise (NSE), the agency that makes nuclear weapons and runs the planes, missiles, and submarines that deliver them.

The warhead “is reinvigorating and transforming the production complex such that NSE can once again produce all of the components typically required for modern nuclear warheads,” according to the Lawrence Livermore National Laboratory, which designed the W87-1. “This work will give the nation expanded options for maintaining an effective nuclear deterrence posture for decades to come.”

Earlier this year, at the annual Nuclear Deterrence Summit in Washington, D.C., there was a palpable sense of excitement at the return to Cold War strategies of shoring up our nuclear arsenal. Today, with what some call the two-peer problem—Russia and China—and the specter of nuclear-armed rogue nations and terrorists, the NSE is racing against what-if targets. The language is aggressive. Opposition is largely mute. Congress has opened the tap. The NSE is hiring, training, building, and spending billions a year.

At Los Alamos, the urgency can be seen inside Plutonium Facility Building 4, known as PF-4, the only building in the United States where plutonium pits are made. Working around the clock, technicians are dismantling old contaminated glove boxes—the laboratory apparatus that allow technicians using built-in gloves to work with toxic or volatile substances inside a sealed chamber—before a new shift of workers arrives to install shiny new steel glove boxes for work on the new pits…………………….

The process of turning plutonium into a bomb is a dark art—an alchemy invented in 1945 on the same New Mexico mesa. Wizards of physics and math who divined the immense energy locked within its atoms, together with master machinists, created the first atomic bomb, “Trinity,” and its copy, “Fat Man,” which destroyed Nagasaki with the power of twenty kilotons, or 20,000 tons of TNT. These two plutonium bombs produced enough heat and radiation to ignite, or trigger, the kind of fusion fire present in the sun.

One year later, as Baby Boom children were teething, Los Alamos blew up a similar plutonium bomb named “Baker” on Bikini Atoll. Its twenty-one-kiloton underwater eruption captured both the bounty of nuclear power and America’s intent to weaponize it.

During the Cold War, Los Alamos produced ninety-four different nuclear weapons—bigger, smaller, deadlier, more accurate. Many were thermonuclear, or hydrogen bombs, whose design, first revealed to the public by Howard Morland in this magazine in 1979, was theorized during the Manhattan Project. In 1952, Los Alamos, using a plutonium pit as a trigger, detonated its first thermonuclear bomb. That same year, the United States built the Rocky Flats Plant, a plutonium pit factory outside Denver. It produced 1,000 pits a year.

The hands-on, metallurgical master craft of fashioning pits was almost lost, though, when Rocky Flats was raided and closed in 1989 by the FBI for massive environmental crimes—the year the Soviet Union began to collapse, ending the Cold War. The NSE fell into a funk, reduced to cleaning up its messes and “stockpile stewardship.”……………………………………………………………………………………………….

“The reestablishment of pit production capabilities is the largest and most complex infrastructure undertaking at NNSA since shortly after the Manhattan Project,” Jill Hruby, administrator of the National Nuclear Security Administration, told the Strategic Weapons in the 21st Century Symposium on April 18. “Our current total estimated acquisition cost range for pit production is $28-37 billion . . . . I know that’s a lot of money . . . . Los Alamos is on track to diamond stamp the first fully qualified War Reserve pit for the W87-1 this year. We anticipate Los Alamos achieving the capability to produce the thirty pits per year envisioned by the two-site plan in or near 2028, with increased manufacturing rate confidence as we install equipment through 2030.”

he United States will never need to make plutonium again. During the Cold War, nuclear reactors at Hanford, Washington, produced more than sixty tons of plutonium. Some 14,000 pits, made by Rocky Flats, each bearing the War Reserve diamond stamp, are warehoused in Pantex, Texas.

As Los Alamos cranks up its program, pits are brought from Pantex, torn apart, and subjected to pyrochemistry, which removes impurities. The metal is then heated into a hot syrup and poured into molds, creating two halves of a sphere. These are welded together. This process is done in rows of connected glove boxes, the plutonium moving from one to another in an overhead trolley system, and dumbwaiters that raise and lower it.

…………………………………………………………………………… fundamental questions are being raised. Scientists debate whether new pits are really needed when existing pits might last for decades. And the need for the W87-1 and the Sentinel missile itself is being questioned because of rising costs and its vulnerability as a land-based, easily targeted weapon. The Pentagon reported in July that the missile’s estimated cost has risen 81 percent over budget to $141 billion.

In New Mexico, two longtime watchdog organizations, the Los Alamos Study Group and Nuclear Watch New Mexico, list dozens of reasons to not make pits at Los Alamos: waste disposal, radiation deposits, earthquake potential, cost and schedule overruns among them.

“Every dollar spent at LANL [Los Alamos National Laboratory] on this program is wasted,” wrote Greg Mello of the Los Alamos Study Group. “Every drum of waste produced in the process need not have been produced. Every career spent making these pits, or supporting the work, is a career that could have been spent building a sustainable, moral, responsible future. The LANL pit production program is a symptom of pure arrogance, greed, and management failure at the highest levels of government.”

………………………. As America’s nuclear train chugs forward, it is virtually certain that if the Sentinel missiles containing the Los Alamos pits are in their silos by the early 2030s, as planned, they will inflame an arms race that is already underway, while posing—if we’re lucky—nothing more than an apocalyptic threat in a new Cold War.  https://progressive.org/magazine/how-to-make-a-war-reserve-nuclear-bomb-carrier-20240905/

Atomic Tragedy? Plutonium Levels Near US Nuclear Site In Los Alamos Similar To Chernobyl – New Study.

 https://www.eurasiantimes.com/plutonium-levels-at-los-alamos-comparab/28 Aug 24

Los Alamos, the birthplace of the American atomic bomb under the Manhattan Project led by Robert Oppenheimer, is now facing a troubling revelation. According to a recent study by Northern Arizona University, plutonium levels in the area are alarmingly high, comparable to those found at the Chernobyl nuclear disaster site. 

The Guardian reported that “extreme concentrations” of plutonium were detected in soil, plants, and water around Los Alamos, a location in New Mexico that was once the center of the US nuclear weapons development. 

These findings were part of a study led by scientist Michael Ketterer, who noted that the levels of this radioactive material were “among the highest” ever found in a publicly accessible area in the US.

His research indicates that these levels are similar to those observed in Chornobyl, Ukraine, the site of the catastrophic nuclear spill during the Soviet era. 

Ketterer expressed shock at the discovery, stating, “This is one of the most shocking things I’ve ever stumbled across in my life.” He highlighted that these radioactive isotopes are “hiding in plain sight,” posing a significant environmental risk. 

Historically, from the 1940s until 1963, the Los Alamos National Laboratory disposed of radioactive waste into a nearby canyon, which eventually earned the nickname Acid Canyon due to its severe contamination. 

The Atomic Energy Commission and the U.S. Department of Energy later initiated a massive remediation effort costing at least $2 billion, which was said to bring the area into compliance with federal cleanup standards by the 1980s. 

The land was subsequently released to Los Alamos County, which developed it into a popular dirt trail for bikers, hikers, and runners. 

Despite the high levels of plutonium detected, Ketterer said that the immediate danger to trail users is low. However, he cautioned that the environmental risks remain significant. 

Plutonium contamination can potentially infiltrate water supplies, ultimately flowing into the Rio Grande, and may enter the food chain through plants. Additionally, in the event of a wildfire, plutonium could be dispersed widely as ash. 

Public health advocates are also urging the government to post signage warning visitors about the contamination, which would allow them to make informed decisions about using the trail.  

Department oF Energy Downplays Risks

Tina Cordova of the Tularosa Basin Downwinders Consortium said that the findings serve as a stark reminder of New Mexico’s long-term radioactive challenges. 

She pointed out that the persistent presence of plutonium, which has a 24,000-year half-life, underscores a “terrible legacy” left by the Trinity bomb, which was notably inefficient and left behind a substantial amount of unfissioned plutonium.

However, the Department of Energy, in response to concerns, said that the detected plutonium levels at Los Alamos are “very low and well within the safe exposure range.”

Similarly, the US Department of Energy’s Environmental Management Los Alamos Field Office maintains that the concerns raised by Ketterer and Nuclear Watch align with data that has been publicly accessible for years and asserts that the canyon remains safe for unrestricted use. 

The Department references a 2018 study that estimates that individuals who frequent the canyon are exposed to less than 0.1 milligrams of radiation annually.

This level is notably lower compared to the average yearly radiation dose of 620 millirems from all sources, as reported by the US Nuclear Regulatory Commission. 

This study indicates that the radiation exposure in the canyon is well below the broader average, highlighting the relatively low risk for those using the area for recreational purposes.

However, Ketterer and his colleague Jay Coghlan, director of Nuclear Watch, caution that while the immediate health risks may be minimal, there are ongoing issues regarding the downstream migration of plutonium, its absorption by plants, and the potential spread of contaminated ash from wildfires. 

Ketterer described the situation as one that cannot be entirely resolved, likening attempts to clean the area to trying to remove salt from a shag carpet. 

He stressed the importance of transparency, suggesting that informing residents and visitors about the contamination is crucial, even if the problem itself cannot be fully rectified.

Meanwhile, the study’s release comes amid the Department of Defense’s announcement to increase plutonium pit production at Los Alamos, a key component in nuclear weapons. 

Concurrently, a defense bill recently approved by the US Senate provides expanded funding for those affected by government-related radioactive waste, but it notably excludes the Los Alamos area, a decision that has sparked outrage among local health advocates.

Extreme’ levels of plutonium contamination found in Los Alamos

  • Levels are comparable to Chernobyl nuclear disaster in Ukraine: Researcher
  • Government says area remains safe
  • Researchers say area visitors must be warned

Safia Samee Ali,  Aug 28, 2024,  https://www.newsnationnow.com/science/extreme-levels-plutonium-contamination-los-alamos/

NewsNation) — High levels of plutonium have been found around Los Alamos, the birthplace of the atomic bomb, raising alarms ahead of plans by the federal government to restart nuclear weapons manufacturing in the same area. 

Michael Ketterer, a Northern Arizona University professor emeritus who analyzed soil, water and vegetation samples taken along a popular hiking and biking trail in Acid Canyon, said that there were more extreme concentrations of plutonium found there than at other publicly accessible sites he has ever researched.

Ketterer has compared the levels to those found at the site of the Chernobyl nuclear disaster in Ukraine. 

“This is one of the most shocking things I’ve ever stumbled across in my life,” he said. 

“It’s just an extreme example of very high concentrations of plutonium in soils and sediments. Really, you know, it’s hiding in plain sight.”

The Department of Energy’s Environmental Management Los Alamos Field Office said that the findings are consistent with department data that has been publicly available for years and that the canyon remains safe for unrestricted use.

But Nuclear Watch, a group Ketterer worked with, said officials need to warn people against coming in contact with water in Acid Canyon.

From 1943 until 1963, liquid and often radioactive waste was dumped down a canyon near Los Alamos National Laboratory, which gave it the name Acid Canyon. 

Jay Coghlan, director of Nuclear Watch, said plutonium contamination in the heart of Los Alamos is a concern, particularly as the Energy Department and the National Nuclear Security Administration are slated to begin producing plutonium pits once again in an effort to build up nuclear weaponry. 

The federal government began cleaning up Acid Canyon in the late 1960s and eventually transferred the land to Los Alamos County. 

Officials determined in the 1980s that conditions within the canyon met DOE standards and were protective of human health and the environment.

High Detections of Plutonium in Los Alamos Neighborhood

As We Enter a New Nuclear Arms Race the Last One is Still Not Cleaned Up

 https://nukewatch.org/high-detections-of-plutonium-in-los-alamos-neighborhood/ 16 Aug 24

Santa Fe, NM – In April Nuclear Watch New Mexico released a map of plutonium contamination based on Lab data. Today, Dr. Michael Ketterer, Professor Emeritus of Chemistry and Biochemistry, Northern Arizona University, is releasing alarmingly high results from samples taken from a popular walking trail in the Los Alamos Town Site, including detections of some of the earliest plutonium produced by humankind.

On July 2 and 17 Dr. Ketterer, with the assistance of Nuclear Watch New Mexico, collected water, soil and plant samples from Acid Canyon in the Los Alamos Town Site and soil and plant samples in Los Alamos Canyon at the Totavi gas station downstream from the Lab. The samples were prepared and analyzed by mass spectrometry at Northern Arizona University to measure concentrations of plutonium, and to ascertain its sources in the environment. For water samples, concentration is expressed in picocuries[1] per liter (pCi/L) and for soil and plants in picocuries per gram (pCi/g). The provenance of the plutonium was determined through isotopic examination of the ratio of 239Pu atoms to 240Pu atoms, which distinguishes it from global nuclear weapons testing fallout.

Acid Canyon is located in the heart of the Los Alamos Town Site, contiguous to the busy Aquatic Center which also has the trailhead for the popular walk into the Canyon. From 1943 to 1963 radioactive liquid wastes were disposed by piping them over the Canyon wall (plutonium is often processed with nitric acid, hence the Canyon’s name). Acid Canyon ultimately drains via the Los Alamos Canyon through San Ildefonso Pueblo lands to the Rio Grande. Earlier studies have identified Lab plutonium as far as 17 miles south in Cochiti Lake.

The Atomic Energy Commission “cleaned up” Acid Canyon in 1967 and released the land to Los Alamos County without restrictions. The Department of Energy performed some additional remediation and in 1984 certified that Acid Canyon was “in compliance with applicable DOE standards and guidelines for cleanup and that radiological conditions were protective of human health and the environment… No monitoring, maintenance, or site inspections are required.” [2]

Forty years later, Dr. Ketterer’s monitoring and inspections strongly indicate otherwise. His samples showed 239+240Pu activities as high as 86 pCi/L in water, 78 pCi/g in sediments, and 5.7 pCi/g in plant ash. He concluded:

“The 239+240Pu activities in all four water samples exceed the federal Environmental Protection Agency’s relevant gross alpha standard of 50 pCi/L and draw attention to an egregious water contamination problem mandating prompt USEPA and/or State intervention. This warrants immediate postings and efforts by State/local agencies to warn people and their pets away from contacting Acid Canyon water.”

While noting the threat of wildfires, as locals will recall the 2000 Cerro Grande Fire that forced the mandatory evacuations of the Lab and Los Alamos Town Site, Dr. Ketterer added,

“Of particular concern is the possibility of wildfire in Acid Canyon. The activity concentrations of 239+240Pu in Acid Canyon sediments and plant matter, along with the Canyon’s close proximity to residential areas of Los Alamos, represents an alarming potential situation of plutonium releases into the air, should a wildfire engulf the canyon.”

Approximately seven miles downstream from Acid Canyon, Dr. Ketterer found “Significant plant uptake of 239+240Pu near the Totavi Philips 66 station along NM Highway 502.”

Of historic interest, he noted,

“The repeated, consistent pattern of 240Pu/239Pu in the range 0.010 – 0.015, observed in the highly contaminated Acid Canyon sediments, water and vegetation, indicates that the Pu in Acid Canyon is some of the oldest known Pu contamination in the ambient environment – a portion of which likely pre-dates the Trinity Test itself.”

Jay Coghlan, Director of Nuclear Watch, commented,

“Dr. Ketterer’s independent sampling of historic plutonium contamination demonstrates once again that we can’t trust the Department of Energy. This rings especially true as LANL plans to cut cleanup while spending at least $8 billion over the next 5 years to expand the production of plutonium “pit” bomb cores. We demand comprehensive cleanup of past radioactive contaminants and protection from the future radioactive wastes that will be generated by the new nuclear arms race.”

Is nuclear waste able to be recycled? Would that solve the  nuclear waste problem?

Radioactive Wastes from Nuclear Reactors, Questions and Answers, Gordon Edwards 28 July 24.

Well, you know, the very first reactors did not produce electricity. They were built for the express purpose of creating plutonium for atomic bombs. Plutonium is a uranium derivative. It is one of the hundreds of radioactive byproducts created inside every uranium-fuelled reactor. Plutonium is the stuff from which nuclear weapons are made. Every large nuclear warhead in the world’s arsenals uses plutonium as a trigger.

But plutonium can also be used as a nuclear fuel. That first power reactor that started up in 1951 in Idaho, the first electricity-producing reactor, was called the EBR-1 — it actually suffered a partial meltdown. EBR stands for “Experimental Breeder Reactor” and it was cooled, not with water, but with hot liquid sodium metal.

By the way, another sodium-cooled electricity producing reactor was built right here in California, and it also had a partial meltdown. The dream of the nuclear industry was, and still is, to use plutonium as the fuel of the future, replacing uranium. A breeder reactor is one that can “burn” plutonium fuel and simultaneously produce even more plutonium than it uses. Breeder reactors are usually sodium-cooled.

In fact sodium-cooled reactors have failed commercially all over the world, in the US, France, Britain, Germany, and Japan, but it is still the holy grail of the nuclear industry, the breeder reactor, so watch out.

To use plutonium, you have to extract it from the fiercely radioactive used nuclear fuel. This technology of plutonium extraction is called reprocessing. It must be carried out robotically because of the deadly penetrating radiation from the used fuel.

Most reprocessing involves dissolving used nuclear fuel in boiling nitric acid and chemically separating the plutonium from the rest of the radioactive garbage. This creates huge volumes of dangerous liquid wastes that can spontaneously explode (as in Russia in 1957) or corrode and leak into the ground (as has happened in the USA). A single gallon of this liquid high-level waste is enough to ruin an entire city’s water supply.

In 1977, US President Jimmy Carter banned reprocessing in the USA because of fears of proliferation of nuclear weapons at home and abroad. Three years earlier, in 1974, India tested its first atomic bomb using plutonium from a Canadian research reactor given to India as a gift.

The problem with using plutonium as a fuel is that it is then equally available for making bombs. Any well-equipped group of criminals or terrorists can make its own atomic bombs with a sufficient quantity of plutonium – and it only takes about 8 kilograms to do so. Even the crudest design of a nuclear explosive device is enough to devastate the core of any city.

Plutonium is extremely toxic when inhaled. A few milligrams is enough to kill any human within weeks through massive fibrosis of the lungs.

A few micrograms – a thousand times less– can cause fatal lung cancer with almost 100% certainty. So even small quantities of plutonium can be used by terrorists in a so-called “dirty bomb”. That’s a radioactive dispersal device using conventional explosives. Just a few grams of fine plutonium dust could threaten the lives of thousands if released into the ventilation system of a large office building.

So beware of those who talk about “recycling” used nuclear fuel. What they are really talking about is reprocessing – plutonium extraction – which opens a Pandora’s box of possibilities. The liquid waste and other leftovers are even more environmentally threatening, more costly, and more intractable, than the solid waste. Perpetual isolation is still required. ————

“Nuclear disarmament is a right to life issue” – Catholic Archbishop John C Wester

 Nuclear weapons were invented here in my Archdiocese. Therefore, I feel a special responsibility to address humanity’s most urgent threat.

“Nuclear disarmament is a right to life issue. No other issue can cause the immediate collapse of civilization. In January 2022 I wrote a pastoral letter in which I traced the Vatican’s evolution from its uneasy conditional acceptance of so-called deterrence to Pope Francis’ declaration  that the very possession of nuclear weapons is immoral. 

“Therefore, what does this say about expanded plutonium pit production at the Los Alamos Lab? And what does it say about the obscene amounts of money that are being thrown at pit production, often excused as job creation?

“What does this say about the fact that the [NNSA] is pursuing expanded pit production without providing the public the opportunity to review and comment as required by the National Environmental Policy Act? I specifically call upon NNSA to complete a new LANL Site-Wide Environmental Impact Statement.

“In two weeks, I travel to Japan for the 79th atomic bombing anniversaries. The bishops of Santa Fe, Seattle, Hiroshima and Nagasaki have a simple message for world leaders. You utterly failed to begin serious negotiations as required by the 1970 NonProliferation Treaty. In this era, you must demonstrate concrete steps toward multilateral, verifiable nuclear disarmament by the 80th bombing anniversaries a year from now.  http://nuclearactive.org/four-archbishops-urge-g7-leaders-to-undertake-concrete-steps-toward-nuclear-disarmament/

“I have a simple message for NNSA and the nuclear weapons labs. You’re very good at creating them. Now show us how smart you are by demonstrating how to get rid of nuclear weapons. Stop this new arms race that threatens all of civilization. Let’s preserve humanity’s potential to manifest God’s divine love toward all beings.

Yongbyon Nuclear Complex: New evidence of increased activity

Night-time lights visible at the Yongbyon radiochemical laboratory suggest that North Korea is covertly importing spent fuel rods for plutonium extraction reprocessing

DAILY NK By Bruce Songhak Chung, 16 July 24

Evidence suggests that North Korea is ramping up production of plutonium and uranium nuclear materials at the radiochemical laboratory and uranium enrichment facility in the Yongbyon nuclear complex, as it has begun full-scale operation of the experimental light water reactor this summer. Recently, major foreign media outlets covering North Korea have debated and verified the reliability of the thermal infrared analysis of the Yongbyon facility presented in a Daily NK column I published in May. This article summarizes thoughts and opinions on this matter, and also examines what is behind the intermittent night lights observed in Yongbyon through night-time luminosity images.

Recent conditions at the Yongbyon reactor and light water reactor area were examined using Maxar’s GeoEye-1 satellite imagery (40 centimeter resolution). In the June 19 satellite photo, heated cooling water from the reactor and light water reactor operation is clearly identified being discharged into the Kuryong River through two pump stations, accompanied by white foam. This marks the 16th cooling water discharge detected this year. As it continues to appear in satellite images since late April, the experimental light water reactor appears to have entered full-scale operation. The South Korean Ministry of National Defense had previously predicted that the Yongbyon light water reactor would enter normal operation in or around the summer months. 

Below the second pump station, a yellow substance spread out in a rectangular shape can be seen on the ground. This could be wheat or barley being dried after harvest. In North Korea, mid-June is the peak harvest time for wheat and barley in the fields, followed typically by planting corn as the year’s second crop. Soldiers and workers guarding the Yongbyon nuclear facility appear to be engaging in farming activities in empty spaces within the complex as food rations are insufficient.

 influential foreign media outlets recently released an assessment about thermal infrared analysis, which is used to determine the operational status of the Yongbyon nuclear facilities. The prominent U.S. North Korea-focused website Beyond Parallel has provided an in-depth analysis of the reliability of thermal infrared data. I read the three articles with great interest. The conclusion of the series of articles evaluated the results of the thermal infrared analysis of North Korea’s Yongbyon nuclear facilities as generally reliable. The outlet explained that after obtaining and comparing Yongbyon facility operation records for over two years held by the U.N., the results largely matched those of the thermal infrared analysis. When high heat was detected in the thermal infrared data, it corresponded with the operation of the Yongbyon facilities. However, the caveat was that facilities operating at low intensity might not be detected due to weak heat emissions. They also recommended drawing comprehensive conclusions by combining thermal infrared analysis with various other data, as there are still imperfections in the analysis. This is valuable advice worth noting.
