Miliband bets on nuclear fusion in bid to lead (?)clean power race.

Energy Secretary to make it easier for developers to build reactors with planning shake-up

 Ed Miliband has taken a bet on nuclear fusion one day powering Britain by
making it easier for developers to build new reactors with minimal planning
restrictions.

Fusion plants are to be included in the UK’s national
infrastructure planning system, meaning they can be built in any part of
Britain without needing consent from local authorities and with little
opportunity for local people to object. Mr Miliband said the aim was to
ensure fusion, if it ever works, could rapidly become part of the UK energy
system.

‘Keeping us hooked on fossil fuels’: how can we negotiate with autocracies on the climate crisis?

 When it comes to the climate crisis, how do you negotiate with an
autocracy? It is the case today, and it is almost certain to remain so for
the dwindling number of years in which we can hope to stave off the worst
of climate breakdown, that the bulk of the world’s greenhouse gas
emissions come from countries that are not democratic. Add to that, many of
the major suppliers of oil and gas – the Gulf petrostates for instance,
plus Russia, Venezuela and a few others – are likewise authoritarian.
Their outsize impact puts autocratic nations in the spotlight when it comes
to global climate talks. How their governments decide to act will be
crucial to the planet’s future. But while democracies are subject to the
whims of electorates, which can often be unpredictable, autocratic nations
tend to be far more inscrutable. Take the small handful of the world’s
biggest fossil fuel companies, referred to as the “carbon majors”. They
hold our future in their hands, and of the top 20 with the biggest carbon
output globally, 16 are state-owned and were responsible for 52% of global
emissions in 2023.

Trump’s nuclear power push weakens regulator and poses safety risks, former officials warn

Spencer Kimball, Jul 17 2025

Key Points

Former NRC commissioners say the order threatens the regulator’s independence, raising safety concerns that could undermine public confidence.

President Donald Trump has ordered an overhaul of the Nuclear Regulatory Commission, part of his push to quadruple nuclear power in the U.S. by 2050.

The order requires the NRC to make decisions on nuclear plants within 18 months, completely revise its regulations and reduce its staff.

Former NRC commissioners say the order threatens the
regulator’s independence, raising safety concerns that could undermine
public confidence. President Donald Trump’s push to approve nuclear
plants as quickly as possible threatens to weaken the independent regulator
tasked with protecting public health and safety, former federal officials
warn.

Trump issued four sweeping executive orders in May that aim to
quadruple nuclear power by 2050 in the U.S. The White House and the
technology industry view nuclear as powerful source of reliable electricity
that can help meet the growing energy needs of artificial intelligence.

The most consequential of Trump’s orders aims to slash regulations and speed
up power plant approvals through an overhaul of the Nuclear Regulatory
Commission. The NRC is an independent agency established by Congress in
1975 to make sure that nuclear reactors are deployed and operated safely.
Trump accuses the NRC of “risk aversion” in his order, blaming the
regulator for how few nuclear plants have been built in the U.S. over the
past three decades. The president says that the NRC is focused on
protecting the public from “the most remote risks,” arguing that such a
cautious approach to approving plants restricts access to reliable
electricity.

Sizewell C | Investor withdraws from consortium set for 25% stake.

17 Jul, 2025 By Tom Pashby, https://www.newcivilengineer.com/latest/sizewell-c-investor-withdraws-from-consortium-set-for-25-stake-17-07-2025/

One of the investors reported to be considering a stake in Sizewell C has decided to withdraw, while the government is no longer planning to classify nuclear energy as “sustainable”.

Schroders Greencoat, which describes itself as “a specialist renewables infrastructure investor”, was previously reported to be one of the companies considering an ownership stake in Sizewell C.

It was widely reported that Schroders Greencoat was one of the companies in the consortium led by Brookfield Asset Management, which was in total considering a 25% stake in the nuclear power plant.

In an email dated 16 July seen by NCE, the investor said it no longer wishes to invest in the project on the Suffolk coast.

Wait for final investment decision continues

Sizewell C must achieve its final investment decision (FID) before main construction can start.

Despite the delay, Sizewell C has committed over £2.5bn on contracts.

The scale of the works are now visible to the public via aerial images taken in April 2025 published on Google Earth and Maps.

It is now expected that the final investment decision will be taken this summer.

Nuclear dropped from sustainable finance classification plans

The UK Government recently decided to not go ahead with plans to create a UK Green Taxonomy for financial investments, meaning that it won’t have a specific classification of certain areas of activity, like nuclear power, as “sustainable”.

This had been a plan hatched by former chancellor Jeremy Hunt in the 2023 Spring Budget, but NCE found that no work had gone towards this 16 months later.

HM Treasury economic secretary to the treasury and city minister Emma Reynolds announced the decision in the UK Green Taxonomy Consultation Response.

“To make sure the UK is well-positioned to capture [growth in the green economy], the government is delivering a world-leading sustainable finance framework,” Reynolds said.

“This includes ensuring that we have the right tools in place and the proportionate regulation that is needed to support the transition, strengthening the UK’s position as the sustainable finance capital of the world so that the UK can lead the clean energy transition at home and abroad.

“That is why, after careful consideration, the government has concluded that a UK Taxonomy would not be the most effective tool to deliver the green transition and should not be part of our sustainable finance framework.

“Whilst our ambitions to continue as a global leader remain unchanged, the consultation responses showed that other policies were of higher priority to accelerate investment into the transition to net zero and limit greenwashing.”

It is understood that the decision to drop plans for the taxonomy may have contributed to Schroders Greencoat’s withdrawal from investing in Sizewell C.

Anti-Sizewell C campaign attributes withdrawal to taxonomy decision

Stop Sizewell C executive director Alison Downes said: “It’s welcome news that Schroders Greencoat won’t be investing in Sizewell C.

Based on our dialogue with Schroders, we attribute this to the government deciding not to adopt a green taxonomy, which thankfully has the outcome that nuclear energy cannot be erroneously labelled ‘green’.

“We wish that other investors would take the same view and exit Sizewell C forthwith.”

No comment from parties to negotiations

The negotiations around the final investment decision are often described as commercially sensitive, and as such the government doesn’t tend to comment.

This hasn’t stopped sources informing the media about certain parts of the negotiations, like the report in the FT that the government is now taking a minority ownership stake.

The Department for Net Zero and Energy Security, Sizewell C and Schroders Greencoat did not supply a comment.

THE END FOR ZELENSKY?

Washington wants the Ukrainian president to leave office—will it happen?

Seymour Hersh, Jul 19, 2025

In fall of 2023, Ukrainian General Valerii Zaluzhnyi, the commander in chief of the country’s armed forces, gave an interview to the Economist and declared the war with Russia had become a “stalemate.” It took three months for President Volodymyr Zelensky to fire him. The general, who is the most popular public figure in Ukraine, was named ambassador to London a month later and has served there with distinction, if quietly.

Zaluzhnyi is now seen as the most credible successor to Zelensky. I have been told by knowledgeable officials in Washington that that job could be his within a few months. Zelensky is on a short list for exile, if President Donald Trump decides to make the call. If Zelensky refuses to leave his office, as is most likely, an involved US official told me: “He’s going to go by force. The ball is in his court.” There are many in Washington and in Ukraine who believe that the escalating air war with Russia must end soon, while there’s still a chance to make a settlement with its president, Vladimir Putin………………………………………………………… (Subscribers only) https://seymourhersh.substack.com/p/the-end-for-zelensky?utm_source=post-email-title&publication_id=1377040&post_id=168643905&utm_campaign=email-post-title&isFreemail=true&r=ln98x&triedRedirect=true&utm_medium=email

Trump Asked Zelensky If He Could Strike Moscow If the US Provided Longer-Range Weapons.

Trump later denied that he was considering sending long-range weapons to Ukraine and said that Ukraine shouldn’t target Moscow

by Dave DeCamp | Jul 15, 2025, https://news.antiwar.com/2025/07/15/trump-asked-zelensky-if-he-could-strike-moscow-if-the-us-provided-longer-range-weapons/

President Trump has encouraged Ukraine to step up strikes deep inside Russia and even asked Ukrainian President Volodymyr Zelensky if his forces were capable of striking Moscow if the US provided longer-range weapons, the Financial Times reported on Tuesday.

Sources told the FT that the conversation occurred during a July 4 phone call. “Volodymyr, can you hit Moscow? . . . Can you hit St Petersburg too?” Trump asked. Zelensky replied that his forces could “absolutely” strike the Russian cities if the US provided the necessary weapons.

The report said that Trump signaled backing for the idea of providing long-range weapons in order to “make them [Russians] feel the pain” to pressure Moscow at the negotiating table. In comments to reporters, Trump later denied that he was considering providing Ukraine with long-range weapons and said that Zelensky “shouldn’t target Moscow.”

The White House confirmed that the conversation about striking Moscow took place, but insisted Trump wasn’t encouraging Ukrainian attacks inside Russia. A White House official told the BBC that Trump was “merely asking a question, not encouraging further killing. He’s working tirelessly to stop the killing and end this war.”

The FT report said that US officials have also provided Zelensky with a list of potential long-range weapons the US could supply. The Ukrainians have been asking for Tomahawk missiles, which have a range of over 1,000 miles, making them capable of hitting Moscow from Ukrainian territory.

Last year, the Biden administration gave Ukraine the green light to use ATACMS missiles in strikes on Russian territory. The ATACMS have a range of about 190 miles, which is not far enough to hit Moscow. Russia has made clear that attacks on its territory risk nuclear escalation since it lowered the threshold for its use of nuclear weapons in response to the US backing the ATACMS attacks.

The revelation about the Trump-Zelensky call came after the US president announced a new plan to provide Ukraine with “billions of dollars” worth of weapons by selling arms to NATO countries that will then transfer them to the war-torn nation. He also threatened major tariffs on Russia and its trading partners if a peace deal isn’t reached in 50 days, an ultimatum Moscow has rejected.

Ian Fairlea critiques New Study on Cancers near UK nuclear facilities

July 16, 2025, https://www.ianfairlie.org/news/new-study-on-cancers-near-uk-nuclear-facilities/

A recent UK study Davies et al (2025) https://doi.org/10.1093/ije/dyaf107 has concluded that no increased cancers occur  near UK nuclear facilities.

This is my initial quick response to this study.

In my view, the new study  has several limitations which inhibit its use a guide to nuclear policy.

First, as the authors admit, it’s an ecological study – the weakest kind of epidemiological study which just looks at incidence data from UK National Statistical tables.  It is much better (but more time-consuming and expensive) to conduct a case-control  study, or even better a cohort  study.

But their discussion refrains from discussing in detail the much better 2008 German KIKK study which was a case-control study and which actually observed a doubling of leukaemia risks and a 60% increase in solid cancer risks near all German NPPs.

Second the study’s methodology is flawed for several reasons. The authors chose (or were instructed to use) a large 25 km radius around UK NPPs even though the better KiKK study showed that almost all cancer cases resided much closer to the NPPs ie within 5 km with very few cases beyond. Also almost  all UK nuclear facilities are on the coast. That means about half the catchment areas here consist of the sea and of course there are no cancer cases there.

The results are that the signal (cancer cases) is diluted …and therefore no increases are detected. It’s almost as if the study were constructed with the aim of not finding any increases. This is not good science.

Third the study refrains from discussing many scientific references by Korblein, by Laurier et al (one is mentioned but their more important ones are not), by myself, and by others,  and as stated above the Kikk study. This is evidence of a biased approach, sorry to say.

Hungary Refuses To Finance US Weapons for Ukraine

Donald Trump has shifted the financial burden of new US weapons to the EU, raising tensions among member states

News Desk, JUL 14, 2025, https://thecradle.co/articles/hungary-refuses-to-finance-us-weapons-for-ukraine

Hungarian Foreign Minister Péter Szijjártó said on 14 July that Hungary will not participate in financing US weapons for Ukraine, even if Washington formally proposes the initiative to the EU.

“I would like to emphasize that Hungarian money, Hungarian weapons, and Hungarian soldiers will not be sent to Ukraine. 

Nothing will be sent there,” Szijjártó stated during a press conference in Budapest following a meeting with Moroccan Minister of Industry and Trade Ryad Mezzour.

Despite this, he expressed support for US President Donald Trump’s so-called peace efforts, stating: “No one has done as much for peace in Ukraine as Trump.” 

He added that these efforts “could have been much more successful in recent months if they hadn’t been obstructed by European and Ukrainian leaders.”

Szijjártó’s remarks came shortly after Trump announced on 14 July that the US would deliver Patriot air defense missiles to Ukraine, saying the EU would cover the full cost.

“We will send them Patriots, which they desperately need … The EU is going to pay us 100 percent for that, and that’s the way we want it,” Trump told reporters at Joint Base Andrews.

Trump framed the weapons transfer as part of a broader strategy to pressure Moscow into negotiations, but did not specify how many systems would be delivered. 

“Putin really surprised a lot of people. He talks nice and then bombs everybody in the evening. But there’s a little bit of a problem there. I don’t like it,” he said.

The announcement coincided with the arrival of Trump’s special envoy, retired Lt. Gen. Keith Kellogg, in Kiev. Ukrainian officials confirmed that discussions would center on weapons, sanctions on Russia, and deepening ties with Washington.

Ukrainian President Volodymyr Zelensky earlier confirmed Kiev’s readiness to purchase Patriot systems and long-range missiles from the US. 

A significant announcement on further arms support is expected from Trump later this week, according to Axios.

Small Nuclear Reactor company’s focus turns to raising $500+ million.

COMMENT. The ask for $500-million has been out there for about two years. Deadbeats, all of them involved in this sorry excuse for a project. It’s pathetic.

It comes after review by Canadian Nuclear Safety Commission that it hopes to parlay into newfound investment

Adam Huras, Jul 10, 2025,
https://tj.news/new-brunswick/smr-companys-focus-turns-to-raising-millions-to-finish-design-work

ARC Clean Technology says its focus is now raising what is likely still the hundreds of millions of dollars it needs to finish the design work of its small modular nuclear reactor.

It’s a figure that’s likely upwards of $500 million, according to two former ARC CEOs.

That’s with the aim to enable NB Power to submit a license to construct application hopefully by 2027, with a target commercial deployment at Point Lepreau in the early 2030s.

It comes after the completion of a review by the Canadian Nuclear Safety Commission that it hopes to parlay into newfound private investment.

Earlier this week, the country’s safety commission said it identified “no fundamental barriers” to licensing the ARC’s proposed sodium-cooled fast neutron reactor, after completing a second design review that had stretched on for over three years.

It’s a result that ARC is calling a “pivotal step” toward commercial deployment.

That’s while adding it gives the company new “global credibility” in a race to market.

Its focus now is raising new money.

“Our current focus is on advancing strategic partnership and investment discussions to set the stage for the next phase of design work to support a license to construct application,” ARC Clean Technology spokesperson Sandra Donnelly told Brunswick News.

Asked specifically how much money is needed, Donnelly declined to say.

“We continue to evaluate the going forward cost estimate through current discussions with strategic partners,” she said.

“We are not sharing specific numbers.”

ARC’s former CEO Bill Labbe had previously said the ARC-100 would cost $500 million to develop and needed an additional $600 million more in power purchase agreements to move the project forward.

That was after the Higgs government gave $20 million to ARC, while the feds awarded the company another $7 million.

Ottawa also provided NB Power with $5 million to help it prepare for SMRs at Point Lepreau.

The Gallant Liberal government also first spent $10 million on ARC and Moltex, the province’s other company pursuing SMR technology, as they set up offices in Saint John now roughly eight years ago.

In an interview with Brunswick News on Thursday, another former ARC president and CEO, Norm Sawyer, who left the company in 2021 and is now a board member at the National Research Council Canada, pegged the figure needed to likely be between US$500 and $700 million.

“A preliminary design is almost essentially complete,” Sawyer said of the Phase 2 review. “Obviously, the next step needs money.

“They would also have to staff up.”

Sawyer said further design work could involve upwards of 100 employees with intensive final engineering to be completed.

That doesn’t include the construction of a facility at Lepreau, Sawyer said.

Brunswick News first reported last spring that ARC had handed out layoff notices to employees, while confirming that, in parallel, its president and CEO since 2021, Labbe, was leaving the company.

Asked if staffing levels will now change, Donnelly said that’s now “being reviewed as part of preparations for the next phase of design work.”

“It’s a positive step for them, it’s just can they leverage it now to get to the next step which is really investment,” Sawyer said. “I think there’s value there for investors.

“It’s also up to how much risk investors are willing to take. I think the investor would want a PPA (power purchase agreement) first.”

A power purchase agreement is a long-term contract where a nuclear power plant sells electricity to a buyer, often a utility, government, or large energy consumer.

NB Power CEO Lori Clark told a committee of MLAs at the provincial legislature earlier this year that ARC is “looking for investors now.”

Clark herself travelled to South Korea last December to promote ARC’s “commercialization possibilities,” in part to drum up new financial support.

A trilateral collaboration agreement was announced last year between South Korea’s utility, ARC, and NB Power with the goal of establishing “teaming agreements for global small modular reactor fleet deployment.”

ARC also said that it welcomed in February “multiple delegations” from South Korea’s utility.

No financial agreement has been revealed as of yet.

Finding the money necessary to finish design work is integral to building timelines.

“Our next objective is to complete the required design work by 2027 to enable NB Power to submit a license to construct application, with a target commercial deployment in early 2030s,” Donnelly said.

“Timelines will continue to be reviewed as design work and partnership discussions progress.”

The company still faces other challenges.

Brunswick News has also reported that ARC is still in search of a new enriched uranium supplier, after it originally planned to buy from Russia. It’s a problem Sawyer has suggested might result in a redesign of the company’s small modular nuclear reactor technology.

Asked if the concern over an enriched uranium source has been resolved, Donnelly said that “the availability of HALEU (high-assay low-enriched uranium) fuel remains an overall market issue.

“We are encouraged that the HALEU supply chain has advanced significantly over the past year with strong government support in multiple countries, and we continue to evaluate multiple options to secure a fuel supply for the first ARC unit,” she added.

The enriched uranium is an integral component of the company’s ARC-100 sodium-cooled fast reactor.

But it’s not as simple as finding that enriched uranium closer to home. While Canada mines uranium, and there are currently five uranium mines and mills operating in Canada, all located in northern Saskatchewan, it does not have uranium enrichment plants.

The U.S. opened its first and only enrichment plant, operated by Centrus Energy in Ohio, amid a federal push to find a solution to the Russia problem. It remains the only facility in the U.S. licensed to enrich uranium, and has a lineup for SMR firms seeking its fuel.

That said, there appeared to be a glimmer of hope on the uranium front late last year as the Trudeau federal government’s fall economic statement promised support to strengthen nuclear fuel supply chains.

“To support demand for allied enriched nuclear fuel and bolster supply chain resiliency, the 2024 fall economic statement announces the government’s intent to backstop up to $500 million in enriched nuclear fuel purchase contracts from the United States or other allied countries, including high-assay low-enriched uranium (HALEU), subject to further consultations with industry stakeholders on program details, and provide $4 million over 10 years, starting in 2024-25, for Natural Resources Canada to administer the program,” reads the fall mini budget.

The current Carney government has yet to table a budget laying out whether that commitment will continue to go ahead.

U.S. and Israeli strikes on Iran could fuel a new wave of nuclear proliferation

 In the wake of recent strikes by Israel and the United States on Iranian
cities, military sites and nuclear facilities, a troubling paradox has
emerged: actions intended to prevent Iran from acquiring nuclear weapons
may actually be accelerating its pursuit of them and encouraging other
countries to follow suit.

Workers at Hinkley Point C nuclear plant stage wildcat strike over alleged bullying

 Hundreds of mechanical engineers stopped work in protest over
‘management practices’ at construction site. A group of mechanical
engineers numbering in the low hundreds stopped work on Tuesday without the
backing of their trade unions amid deepening woes within the 26,000-strong
workforce over the conditions on the site.

It was the second unofficial
strike to take place in a week after a walkout last Wednesday in defiance
of union reps and the site developer, French utility company EDF, following
claims that senior managers on the Hinkley site have bullied engineering
staff. A contract worker on the project, which is running years late and
billions of pounds over budget, told the Guardian one of the incidents was
believed to have involved a senior manager bullying a young woman on the
team.

“They’ve had enough, and they’re out the gate,” he said.
Trade union Unite confirmed that a number of workers are taking part in a
protest over “management practices” which has resulted in the workers
being removed from the site. “Unite expects this matter to be resolved
soon,” a spokesperson said. The Guardian understands that EDF, which is
developing the first new nuclear reactor in a generation at Hinkley Point,
has begun an independent investigation into the alleged bullying on site.
The row has emerged days after the UK nuclear watchdog confirmed it would
prosecute EDF alongside the site’s main contractors Bouygues Travaux
Publics and Laing O’Rourke for health and safety offences over the death
of a site supervisor at the site after an accident in 2022.

80 Years Ago: The First Atomic Explosion, 16 July 1945.

James B. Conant’s Eyewitness Account:
“The Whole Sky Suddenly Full of White Light Like the End of the World”

1,100 Square Miles in New Mexico Exposed to Radioactive Contamination

UCLA Report Suspected “Many Potential Long-Term Insidious Hazards” From Trinity Test Radiation

Washington, D.C., July 16, 2025 – Early in the morning of 16 July 1945, 80 years ago today, the U.S. Manhattan Project staged the first test of a nuclear weapon in the New Mexican desert. It was the first trial of a plutonium implosion weapon—the same weapon type that devastated Nagasaki a few weeks later. The explosion on the ground produced radioactive fallout contaminating over 1,100 square miles of the state, with some debris spreading as far north as Canada. Six weeks after the test, a “swath of fairly high radioactivity on the ground cover[ed] an area of about 100 miles long by 30 miles wide,” according to a Los Alamos Laboratory report published today for first time by the National Security Archive, while “gamma radiation was found in measurable but very low intensities in Santa Fe, Las Vegas, Raton and even in Trinidad, Colorado,” 260 miles from the point of detonation.

To mark the anniversary of this world-historic event, the National Security Archive today published a collection of essential declassified documents on the first atomic bomb test and the radioactive contamination that preoccupied government officials and medical experts during the years that followed. The new posting builds upon an Electronic Briefing Book of documents, photos, and period films published last year by the Archive, fortifying it with a number of significant new records, including:

  • memoranda sent to Manhattan Project director Gen. Leslie R. Groves by his Scientific Advisor Richard C. Tolman on the so-called “100-ton test”—the Trinity “dress rehearsal”—and the reasons for holding a test of the implosion device at the Trinity site,
  • Manhattan Project Director General Leslie Groves’ phoned-in message on the test minutes after it occurred, reporting that results were “probably … above expectations,”
  • reports by Chief of British Mission Sir James Chadwick on the Test, who wrote, “Even now, a week later, I am filled with awe when I look back at this moment. It was a vision from the Book of Revelation,”
  • and Harvard University President James B. Conant’s dramatic firsthand account of the test, observing that “the enormity of the light and its length quite stunned me.”

The Trinity Test planners prepared for possible adverse public health effects but did not know how far radioactive debris would spread, and the biological and public health impact of low-level radiation is still a contested issue. But during the years after Trinity, researchers with the Atomic Energy Project at the Medical School of the University of California, Los Angeles (UCLA) collected evidence to help determine whether the fallout produced a health hazard. While the studies drew no firm conclusions, a 1951 report by the Project found that there were “many potential long-term insidious hazards from the present low-level contamination which is the focal point of these studies.” The possibility that such hazards could eventually inspire legal action was concerning to medical experts who also wanted to learn more about the military implications of low levels of radiation contaminating “large land areas,” leading the Atomic Energy Commission to fund a research program at UCLA to determine the scope and impact of the contamination.

The Trinity test took place 80 years ago, but it is not entirely in the past. Researchers at the National Cancer Institute have determined that the test’s fallout contributed to excess numbers of thyroid cancers. To this his day, “down winders” in New Mexico seek federal compensation under the Radiation Exposure and Compensation Act (RECA), which so far has excluded that state, even though 33 of its counties, including tribal areas, experienced levels of radiation exposure that were higher than other U.S. counties covered by the Act.

Improvements required at Sellafield after lead oxide release

 The Office for Nuclear Regulation (ONR) has served an improvement notice
on Sellafield Ltd following an incident at the Cumbria site. In April, an
unintentional release of lead oxide was detected at the First Generation
Magnox Storage Pond (FGMSP) facility when workers noticed the degraded
condition of some flexible lead shielding.

Lead shielding sheets are used
across the site to protect workers from potential exposure to radiation.
The coating on the sheets used on the FGMSP skip handling machine had
degraded over time, resulting in lead oxide being released which posed a
potential risk to workers. Further enquiries have identified a number of
other locations across the Sellafield site where degraded flexible lead
shielding sheets caused a risk of lead exposure. Lead oxide is not a
radioactive substance, but can be harmful if ingested, inhaled or absorbed.

Nuclear waste exposure in childhood associated with higher cancer incidence

Harvard T.H. Chan School of Public Health, Jul 17 2025, https://www.news-medical.net/news/20250717/Nuclear-waste-exposure-in-childhood-associated-with-higher-cancer-incidence.aspx

Living near Coldwater Creek-a Missouri River tributary north of St. Louis that was polluted by nuclear waste from the development of the first atomic bomb-in childhood in the 1940s, ’50s, and ’60s was associated with an elevated risk of cancer, according to a new study led by Harvard T.H. Chan School of Public Health. The researchers say the findings corroborate health concerns long held by community members.

The study will be published July 16 in JAMA Network Open. It coincides with Congress having passed an expanded version of the Radiation Exposure Compensation Act (RECA) as part of the Trump tax bill, through which Americans, including Coldwater Creek residents, can receive compensation for medical bills associated with radiation exposure.

Most studies of radiation exposure have focused on bomb survivors who have had very high levels of exposure; far less is known about the health impacts of lower levels of radiation exposure. 

For this study, the researchers used a subsample of 4,209 participants from the St. Louis Baby Tooth – Later Life Health Study (SLBT), a cohort composed of many individuals who lived near Coldwater Creek as children and who donated their baby teeth beginning in 1958 to measure exposure to radiation from atmospheric nuclear testing. The participants, who lived in the Greater St. Louis area between 1958 and 1972, self-reported incidences of cancer, allowing the researchers to calculate cancer risk in accordance with childhood residence proximity to Coldwater Creek.

The findings showed a dose-response effect-those living nearest to the creek had a higher risk for most cancers than those living farther away. There were 1,009 individuals (24% of the study population) who reported having cancer. Of those, the proportion was higher for those living near the creek-30% lived less than one kilometer away, 28% between one and five kilometers away, 25% between five and 20 kilometers away, and 24% 20 kilometers or more away). 

The researchers estimated that those living more than 20 kilometers away from the creek had a 24% risk of any type of cancer. Compared to this group, among those who lived less than one kilometer away from the creek, the risk of developing any type of cancer was 44% higher; solid cancers (cancers that form a mass, as opposed to blood cancers), 52% higher; radiosensitive cancers (thyroid, breast, leukemia, and basal cell), 85% higher; and non-radiosensitive cancers (all except thyroid, breast, leukemia, and basal cell), 41% higher. The risk went down among those who lived between one and 5 kilometers away from the creek, and then down a little more among those who lived 5-20 kilometers away, but was still slightly higher than those living more than 20 kilometers away.

“Our research indicates that the communities around North St. Louis appear to have had excess cancer from exposure to the contaminated Coldwater Creek,” said corresponding author Marc Weisskopf, Cecil K. and Philip Drinker Professor of Environmental Epidemiology and Physiology.

These findings may have broader implications-as countries think about increasing nuclear power and developing more nuclear weapons, the waste from these entities could have huge impacts on people’s health, even at these lower levels of exposure.”
