The physical hazards of nuclear energy
Mark Diesendorf: The debate about the economics of nuclear energy versus
renewable energy has distracted politicians, the media and members of the
public from the physical hazards of nuclear energy. The three principal
hazards are its contribution to the proliferation of nuclear weapons, the
risk of nuclear accidents, and the impossible task of managing nuclear
wastes for 100,000 years. This article offers a concise review, drawing
attention to some issues that are not widely known, including a fourth
hazard, radiation exposure of the unborn child. I write wearing the hat of
a physicist.

United States: White House Threatens Nuclear Regulatory Commission’s Independence

Energy Intelligence Group, Jessica Sondgeroth, Washington, 21 Feb 25,
The Trump administration’s expansive assertion of presidential power now threatens the independence of the US Nuclear Regulatory Commission (NRC) after the White House this week issued an executive order (EO) claiming control over federal agencies that were established to be independent of politics. The Feb. 18 EO tasks the White House’s Office of Management and Budget (OMB) with the authority to manage independent agencies’ obligations and spending to ensure they align with “the President’s policies and priorities.” These agencies will also have to submit for review to an OMB office “all proposed and final significant regulatory actions.” The extent to which this erodes the NRC’s independence may vary depending on how NRC responds and on OMB actions taken, but nuclear energy sector veterans, critics and advocates are nonetheless waving red flags.
The White House decision “to meddle in safety regulation” is “devastating,” former NRC chair Allison Macfarlane, now a policy professor at the University of British Columbia, told Energy Intelligence. “The US NRC used to be referred to as the ‘gold standard’ for nuclear regulators. No longer. Now other countries can take that mantle.” Macfarlane said that as NRC chair, she spent years championing regulatory independence “to ensure national security and economic security. A nuclear accident, as happened in Japan, can devastate a country’s economy, not to mention its nuclear industry. I guess the folks at the White House have never learned this lesson?”
The EO, titled “Ensuring Accountability for All Agencies”, is only the latest White House challenge to the independence of various executive agencies and to Congressional lawmaking, from science and health research to environmental oversight to public education. This particular EO seeks to broaden the White House’s authority over independent regulatory agencies, including the Federal Trade Commission, Federal Energy Regulatory Commission, Federal Communications Commission and Securities and Exchange Commission. The EO does make some exceptions, but the NRC is not among them.
……………………………………………Given “the blatant and unmitigated conflicts of interest in the White House, and the newfound love among Trump and Elon [Musk]’s tech bro friends for nuclear power,” Ed Lyman, a nuclear regulatory watchdog at the Union of Concerned Scientists, warned in an email that the agency “could be turned into a mere rubber stamp for whatever projects are favored by the President at the moment.” This could override the NRC’s “public health and safety mandate in the name of ‘consistency with the President’s policies and priorities.'”
The NRC was established as an independent agency by Congress in the Energy Reorganization Act of 1974. That law took the NRC’s predecessor, the Atomic Energy Commission, and split its regulatory and promotional roles into the NRC and what is today the US Department of Energy (DOE), respectively. “The NRC was explicitly created to be independent of energy system policy goals under the Atomic Energy Commission that Congress perceived as too political and influenced by the industry,” Adam Stein, nuclear energy innovation director, noted. “Shifting from an independent agency to an agency under direct control of one party under the President creates the same problem from a different influence.”
……………………The nuclear industry lobbies Congress for favorable policies but also communicates directly with the NRC through filings and public meetings to advocate for its interpretation of Congressionally-mandated regulatory reforms.
…………………….For agencies as specialized as the NRC, mass layoffs or buyouts threaten to undermine core competencies and training activities — particularly given the recent hiring of 600 staff, a growing workload of new reactor licensing activities and concerns over the aging workforce.

The IAEA comments on the state of Ukraine’s Nuclear Power Plants

The Zaporizhzhya Nuclear Power Plant has been relying on a single off-site power line for more than a week now after the other 9 have been taken offline due to the war – this single power line is critical to prevent massive radioactive releases at the site.
At the Chornobyl plant, firefighters are continuing to put out small fires that keep smouldering and spreading on the roof of the reactor shield hit by a Russian drone.
Ukraine’s other nuclear plants have continued to report frequent air raid alarms over the past week due to the presence of drones around the sites.
5.0-magnitude quake strikes off Japan’s Fukushima: JMA
TOKYO, Feb. 21 (Xinhua) https://english.news.cn/20250221/1a62306993674102b4bf547c66308416/c.html?fbclid=IwY2xjawInSGJleHRuA2FlbQIxMQABHaLmlIJlO8LIDD4_tC9mDYzpZnPQTSalQEzW0hj-j5vNUxWQ8hVw_Wrelw_aem_JSAQL14AGKbnrwbZ10cXPA
— An earthquake with a preliminary magnitude of 5.0 struck off the northeastern Japanese prefecture of Fukushima on Friday, the country’s weather agency said.
The temblor occurred at around 10:01 p.m. local time at a depth of 50 km, measuring 4 on the Japanese seismic intensity scale of 7, according to the Japan Meteorological Agency (JMA).
The epicenter was located at a latitude of 37.5 degrees north and a longitude of 141.5 degrees east.
There was no tsunami warning, the JMA added
Trump just assaulted the independence of the nuclear regulator. What could go wrong?

By Allison Macfarlane | February 21, 2025
President Trump, through his recent Executive Order, has attacked independent regulatory agencies in the US government. This order gives the Office of Management and Budget power over the regulatory process of until-now independent agencies. These regulatory agencies include the Federal Elections Commission, the Federal Trade Commission, the Securities and Exchange Commission, the Federal Energy Regulatory Commission—and my former agency, the Nuclear Regulatory Commission, which I chaired between July 2012 and December 2014.
An independent regulator is free from industry and political influence. Trump’s executive order flies in the face of this basic principle by requiring the Office of Management and Budget to “review” these independent regulatory agencies’ obligations “for consistency with the President’s policies and priorities.” This essentially means subordinating regulators to the president.
In the past, the president and Congress, which has oversight capacity on the regulators, stayed at arm’s length from the regulators’ decisions. This was meant to keep them isolated, ensuring their necessary independence from any outside interference. Trump’s executive order implies there are no longer independent regulators in the United States.
Independent regulators should not only be free from government and industry meddling; they also need to be adequately staffed with competent experts and have the budget to operate efficiently. They also need to be able to shut down facilities such as nuclear power plants that are not operating safely, according to regulations. To do this, they need government to support their independent decisions and rulemaking.
Independence matters. When I was chairman, I traveled the world talking about the importance of an independent regulator to countries where nuclear regulators exhibited a lack of independence and were subject to excessive industry and political influence. It is ironic that the US Nuclear Regulatory Commission—often called the “Gold Standard” in nuclear regulation—has now been captured by the Trump administration and lost its independence. So much for the Gold Standard; the Canadian, the French, or the Finnish nuclear regulator will have to take on that mantle now.
To understand what is at stake, one needs to look no further than the Fukushima accident in March 2011, which showed the world how a country’s economic security is vulnerable to a captured regulator………………………………………………………..
An independent investigation by the Diet (Japan’s house of parliament) into the cause of the Fukushima accident concluded unequivocally that: “The TEPCO Fukushima Nuclear Power Plant accident was the result of collusion between the government, the regulators and TEPCO, and the lack of governance by said parties. They effectively betrayed the nation’s right to be safe from nuclear accidents.” Japan’s government and nuclear industry continue to struggle with the clean-up of the Fukushima site, and it purposely began in 2023 to release still-contaminated water into the Pacific Ocean. Nearby countries responded by banning fishing products from the region.
As the industry often says, a nuclear accident anywhere is a nuclear accident everywhere. …………………… more https://thebulletin.org/2025/02/trump-just-assaulted-the-independence-of-the-nuclear-regulator-what-could-go-wrong/?fbclid=IwY2xjawImRopleHRuA2FlbQIxMQABHXcsEIvbsR7x3_k1wSvr8EHSizxiqUnLBb42mZ2YJGeOYLxrftrY4-5HVg_aem_Q1k1WJJnpyqw6WEHOuvZ2Q
Efforts continue to eliminate fires in Chernobyl shelter’s roof
In an update on Thursday at 17:00 local time, the Chernobyl nuclear power plant operator said thermal imaging monitoring of the New Safe Confinement was continuing and parts of the exterior cut into “for the final elimination of smouldering areas”.
Workers from the State Emergency Service of Ukraine have been working at the site since the drone strike on Friday 14 February damaged the roof of the giant structure built to cover Chernobyl’s unit 4.
The Chernobyl plant company (ChNPP) said that the external cladding of the arch-shaped New Safe Confinement (NSC) had a 15 square metre area of damage from the drone, with further damage in areas up to 200 square metres. It said there was also damage to the internal cladding filler and to some bolted connections in the structure.
It says that radiation levels remain within their normal levels at the site – the NSC was built to cover a wide area, including the original rapidly built shelter over the remnants of unit 4 following the accident in 1986.
In its update on Thursday, the International Atomic Energy Agency, which has experts based at Chernobyl, said: “Firefighters are continuing to put out small fires that keep smouldering and spreading on the roof of the New Safe Confinement.” It added that agency staff’s “measurements continue to show normal gamma radiation dose rate values near the NSC compared to those recorded by the IAEA since it established a continuous presence at the site just over two years ago”………………………………………….

“Radioactive Russian Roulette” at San Onofre: Exposing Critical Safety Failures.
Charles Langley of Public Watchdogs has exposed a critical issue that demands immediate attention: the Nuclear Regulatory Commission (NRC) has granted Southern California Edison (SCE) sweeping exemptions from emergency planning and safety requirements, putting millions of lives at risk. These alarming exemptions—despite strong objections from state officials—leave the public dangerously unprotected in the event of a nuclear emergency.

NFLA Policy Briefing 313: Correspondence with the Nuclear Regulator over AGR Extensions
We note the recent EDF press release stating that a decision to life-extend
all four remaining AGR stations has been taken by EDF with Heysham 1 and
Hartlepool extended to 2027 and Heysham 2 and Torness extended to 2030.
The ONR site says for Heysham 1 and Hartlepool that: ‘EDF have recently
communicated their decision [March 2023] to extend the generating lifetime
of the station to March 2026, subject to an adequate demonstration of
safety.’ But there is no further information on whether an adequate
demonstration of safety has been submitted and assessed, and no mention of
extension to 2027.
For the other two AGR stations, no mention is made on
the ONR site of EDF’s intention to life-extend the plants, and the EDF and
the ONR sites give a forecast end of generation as 2028 for the two AGRs.
On your questions regarding EDF’s press release, the results of the EDF
inspections indicated that the graphite cores remained within the
limitations of the current safety cases.
The results of these inspections
have not been published by EDF. These inspections informed EDF’s commercial
judgement to pursue lifetime extensions; it is not within ONR’s scope of
regulation to consider the commercial viability of the life extension of
these reactors.
It is likely that EDF will require new safety cases to
justify operation to the specified end of generation dates and these will
be considered by ONR as part of normal regulatory activities.

Damage to Chernobyl shelter being assessed after drone strike

World Nuclear News 17 February 2025, https://www.world-nuclear-news.org/articles/damage-to-chernobyl-shelter-being-assessed-after-drone-strike
Firefighters worked across the weekend to tackle smouldering roof insulation in the giant protective shelter which covers Chernobyl’s unit 4 following the drone strike on Friday. Radiation levels in the area remain normal – the original protective shelter inside the giant structure did not suffer any damage.
The State Emergency Service of Ukraine said on Monday morning there were three groups of climbers tackling three smouldering areas of the roof insulation on the New Safe Confinement. According to SSE ChNPP – which runs the Chernobyl site and decommissioning activities – radiation levels have remained normal throughout, with 84 people working at the scene as of Saturday afternoon, as they sought to wet the smouldering insulation and stop the spread.
It reported that a 15 square metres area of the external cladding of the arch-shaped New Safe Confinement was damaged at a height of about 87 metres, as well as wider “sheathing defects” for an area of about 200 square metres. Damage to both the outer and inner shell of the structure was identified.
The International Atomic Energy Agency, which has experts stationed at Chernobyl, said that the efforts to “put out and prevent the spread of any remaining fires – apparently fuelled by inflammable material in the roof cladding” had delayed work to start repairing the damage to the New Safe Confinement.
IAEA Director General Rafael Mariano Grossi said: “This was clearly a very serious incident, with a drone hitting and damaging a large protective structure at a major nuclear site. As I have stated repeatedly during this devastating war, attacking a nuclear facility is an absolute no-go, it should never happen. It is especially concerning as it comes as we are also seeing an increase in military activity in the area around the Zaporizhzhia nuclear power plant. The IAEA remains committed to doing everything we can to help prevent a nuclear accident.”
The IAEA said their team “confirmed that both the outer and inner cladding of the NSC arch had been breached, causing a hole measuring approximately six metres in diameter and also damaging some equipment as well as electrical cables. However, the structural support beams did not appear to have suffered major damage”.
The European Bank for Reconstruction and Development, which oversaw the shelter project and which together with 45 donors helped fund the EUR2 billion (USD2.1 billion) construction costs of the New Safe Confinement, said it “stands ready to support the government of Ukraine and partners” to ensure Chernobyl remains an environmentally safe and secure site.
What is the New Safe Confinement?
Chernobyl Nuclear Power Plant’s unit 4 was destroyed in the April 1986 accident (you can read more about it in the World Nuclear Association’s Chernobyl Accident information paper) with a shelter constructed in a matter of months to encase the damaged unit, which allowed the other units at the plant to continue operating. It still contains the molten core of the reactor and an estimated 200 tonnes of highly radioactive material.
However it was not designed for the very long-term, and so the New Safe Confinement – the largest moveable land-based structure ever built – was constructed to cover a much larger area including the original shelter. The New Safe Confinement has a span of 257 metres, a length of 162 metres, a height of 108 metres and a total weight of 36,000 tonnes and was designed for a lifetime of about 100 years. It was built nearby in two halves which were moved on specially constructed rail tracks to the current position, where it was completed in 2019.
It has two layers of internal and external cladding around the main steel structure – about 12 metres apart – with the IAEA confirming that both had been breached in the incident. The NSC was designed to allow for the eventual dismantling of the ageing makeshift shelter from 1986 and the management of radioactive waste. It is also designed to withstand temperatures ranging from -43°C to +45°C, a class-three tornado, and an earthquake with a magnitude of 6 on the Richter scale.
According to World Nuclear Association, the hermetically-sealed New Safe Confinement allows “engineers to remotely dismantle the 1986 structure that has shielded the remains of the reactor from the weather since the weeks after the accident. It will enable the eventual removal of the fuel-containing materials in the bottom of the reactor building and accommodate their characterisation, compaction, and packing for disposal. This task represents the most important step in eliminating nuclear hazard at the site – and the real start of dismantling”.
The wider context
Chernobyl nuclear power plant lies about 130 kilometres north of Ukraine’s capital Kyiv, and about 20 kilometres south of Belarus. A 30-kilometre exclusion zone remains around the plant, although some areas have been progressively resettled. Three other reactors at the site, which was built during Soviet times, continued to operate after the accident, with unit 3 the last one operating, until December 2000.
When Russia launched its invasion of Ukraine in February 2022 it rapidly took control of the Chernobyl plant. Its forces remained there until withdrawing on 31 March 2022 and control returned to Ukrainian personnel. The IAEA has had experts stationed at the site as the war has continued, seeking to help ensure the safety and security of the site.
IAEA teams are also in place at Ukraine’s three operating nuclear power plants and the Zaporizhzhia nuclear power plant, which has been under the control of Russian forces since early March 2022.
Ukraine has blamed Russia for the drone strike, while Russia denied it was responsible and blamed Ukraine. The IAEA has not attributed blame to either side during the war, with Director General Grossi explaining in a press conference at the United Nations in April last year that this was particularly the case with drones, saying “we are not commentators. We are not political speculators or analysts, we are an international agency of inspectors. And in order to say something like that, we must have proof, indisputable evidence, that an attack, or remnants of ammunition or any other weapon, is coming from a certain place. And in this case it is simply impossible”.
Nuclear expert issues Chernobyl update after it emerges fires are still burning.
Luke Alsford and Gergana Krasteva, Metro UK, February 16, 2025
Flames are still raging inside the Chernobyl nuclear station after multiple fires yesterday.
Three smoldering fires were detected earlier this morning, forcing teams to jump into action to prevent a disaster at the power plant.
Ukraine’s state agency on exclusion zone management confirmed that no release of radioactive material has been reported yet.
The plant was hit on Friday by a drone carrying a high-explosive warhead, according to Ukraine, 38 years after the nuclear explosion at the site…..
Firefighters continue to battle the blaze round the clock in challenging weather conditions, admitted the International Atomic Energy Agency.
The plant’s fourth reactor now has a 314 square foot gash after the drone strike.
Although no rise in radiation has been reported yet, an expert issued a frightening warning about how Russia’s attack will soon affect nearby radioactivity
Dr Olga Kosharna, founder of the Anti-Crisis Expert Nuclear Centre of Ukraine, said: ‘The hermetic seal has been broken.
‘It is clear that the ventilation systems will [work] differently and the radiation level will increase.
‘But I think that it will not go beyond the industrial site and the exclusion zone.
Chernobyl’s reactors are covered by an outer dome to prevent radioactive leakage after the 1986 disaster – the world’s worst civilian nuclear accident – which sent pollution spewing across Europe.
Video footage shows how the explosion blew a hole in the dome at 1.50am on Friday, before a fire then broke out.
An open fire on the roof structure – officially called the New Safe Confinement (NSC) – was swiftly put out by first responders.
However smouldering fires remain inside the 20ft diameter hole.
The International Atomic Energy Agency [IAEA] said: ‘The ongoing efforts to put out and prevent the spread of any remaining fires – apparently fuelled by inflammable material in the roof cladding – have delayed work to start repairing the damage.’
The organisation’s director Rafael Mariano Grossi added: ‘This was clearly a very serious incident, with a drone hitting and damaging a large protective structure at a major nuclear site.
‘As I have stated repeatedly during this devastating war, attacking a nuclear facility is an absolute no-go, it should never happen.’
Grossi also warned of an ‘increase in military activity in the area around the Zaporizhzhia Nuclear Power Plant.
‘The IAEA remains committed to doing everything we can to help prevent a nuclear accident. Judging by recent events, nuclear safety remains very much under threat.’…………………………….

High-Explosive Drone Pierces Shell Of Chernobyl Nuclear Plant At Very Moment Trump Pushes Ukraine Toward Peace

by Tyler Durden, Saturday, Feb 15, 2025, https://www.zerohedge.com/geopolitical/high-explosive-drone-pierces-shell-chernobyl-nuclear-plant-very-moment-trump-pushes
On Friday just prior to high-level meetings among Western security officials and Ukrainian leadership commencing in Munich, including US Vice President J.D. Vance and Zelensky, there was a dangerous incident at the Chernobyl Nuclear Power Plant in Ukraine’s Kyiv oblast.
Ukraine’s President Zelensky accused Russia of launching a drone equipped with a high-explosive warhead at the historic, defunct power plant, site of the April 1986 nuclear disaster and meltdown. The drone reportedly hit the protective containment shell of the Chernobyl plant.
Zelensky’s office released footage showing an impact to the giant concrete and steel shield protecting the remains of the nuclear reactor. BBC writes that “The shield is designed to prevent further radioactive material leaking out over the next century. It measures 275m (900ft) wide and 108m (354ft) tall and cost $1.6bn (£1.3bn) to construct.”
And WaPo details further of the looming potential dangers:
In 2019, construction was completed on the New Safe Confinement — a $1.7 billion arch-shaped steel structure, which would contain the destroyed reactor. The site still contained some “200 tons of highly radioactive material,” according to the European Bank of Reconstruction and Development, which helped finance the project.
Thus the situation is deeply alarming given the potential for a new radiation leak at the site which could impact the region, or even Europe. An IAEA team on the ground said it heard an explosion at around 01:50 local time coming from the New Safe Confinement (NSC) shelter. Photos showed flames at the top of the huge structure.
The UN agency is on high alert, but issued a statement saying the drone strike did not breach the plant’s inner containment shell. The IAEA also did not attribute blame, not identifying who sent the drone.
The Kremlin strongly rejected that it was behind the incident:
“There is no talk about strikes on nuclear infrastructure, nuclear energy facilities, any such claim isn’t true, our military doesn’t do that,” Peskov told reporters in a call.
Russian state media has meanwhile been warning of efforts by bad actors to sabotage Trump’s peace plan for Ukraine, after he held a 90-minute phone call with President Vladimir Putin this week.
Serious damage to the protective shield remains, which could present an ongoing serious safety issue at the site:
Simon Evans from the European Bank for Reconstruction and Development (EBRD) was head of the Chernobyl Shelter Fund, which oversaw the construction of the protective dome in the 2010s.
He described the apparent strike as “an incredibly reckless attack on a vulnerable nuclear facility”.
The shield “was never built to withstand external drone attack”, he told the BBC.
Given this, why would Russia at this very moment while Trump and Putin are trying to line up peace talks launch a high-explosive drone at the Chernobyl Nuclear Power Plant?
Cui bono?…
Zelensky has asserted that Putin is not actually ready for or seeking legitimate negotiations, contradicting recent statements coming from the Trump White House.
On Friday, he claimed: “The only country in the world that attacks such sites, occupies nuclear power plants, and wages war without any regard for the consequences is today’s Russia.”
Meanwhile, Ukraine’s State Nuclear Regulatory Inspectorate has in a fresh statement said that while the drone damaged “the external integrity” of the New Safe Confinement “and equipment in the crane maintenance garage” – it remains that there are no observable radiation spikes. “Firefighting efforts and damage assessment are ongoing,” it added.
Was this a desperate CHERNOBYL 2.0 ATTEMPT? Whodunnit?
Given that Chernobyl is a name that has captured popular imagination for decades since the apocalyptic historic disaster left the vicinity basically a radiation death zone, it could present the perfect false flag opportunity for anyone wishing to prolong and escalate the war.
A dramatic development in the Ukraine situation.
18 February 2025 https://theaimn.net/a-dramatic-development-in-the-ukraine-situation/
The shut-down Chernobyl nuclear reactor was hit by a drone on 14th February, and its outer covering was breached. The International Atomic Energy Agency (IAEA) was quick to gloss over the impact from the latest incident involving the wrecked Chernobyl nuclear reactor – ” Radiation levels inside and outside the so-called New Safe Confinement building “remain normal and stable,”….. and there are no reports of any casualties or radiation leak.”
To be fair, the IAEA did not attribute blame to Russia. Le Monde stated that the cause was a Russian Shahed drone, armed with a high-explosive warhead. So, it actually does look as if the offending drone came from Russia. But that is not certain. However, as far as the Western media goes – the issue is being covered as a deliberate attack by Russia. Youtube after Youtube video, article after article, blames Russia, and repeats Zelensky’s claims –“This is a terrorist attack for the entire world.” Zelensky spoke at the Munich Security Conference accusing Russia of a deliberate attack. Even if it was a Russian drone, there remains the possibility that this was a mistake, rater than intentional. What would Russia have to gain by this? Cui bono?
This event is significant in two ways – First – it could throw a spanner in the works of the current discussions on ending the war in Ukraine . These peace discussion are a whole nother story. Donald Trump is no doubt looking for a way for USA business interests to grab Ukraine resources as one large part of a peace deal in which Russia keeps its invaded territory. Zelensky’s presidency sort of ended on 20 May 2024 – he stays in power because it is war-time – which may well be part of his desire to keep the ear going, no matter what the cost. Zelensky seems to have cast some sort of mesmerising spell over Europe – depicting the Russian bear salivating to gobble up Europe. Good loyal Westerners seem pretty much obligated to oppose Donald Trump on all matters. However a plan to allow some concessions to Russia is a militarily reasonable way to end this war.
Secondly, it could really demonstrate the hypocrisy of the IAEA and its Director Rafael Grossi about nuclear safety

Does anyone really think that this Chernobyl incident is over? All sorted?
“Flames are still raging inside the Chernobyl nuclear station after multiple fires yesterday.” – Luke Alsford and Gergana Krasteva, Metro UK, February 16, 2025
Alsford and Krasteva set out in chilling (perhaps that’s not the right word) detail, the efforts going on, in extreme weather conditions, to prevent a disaster at the power plant, firefighters battling the blaze around the clock. The reactor’s containment shell. now has a 314 square foot gash. With the hermetic seal broken, the ventilation system is affected, and the radiation level will increase.
Those courageous workers at the wrecked Chernobyl nuclear power plant will probably get those fires out before it all gets much, much worse. And mend the hole in the containment shell. And the IAEA and everyone else will breathe sighs of relief. Until the next nuclear near-miss.

Restless radioactive remains are still stirring in Chernobyl’s nuclear tomb.


‘It’s like the embers in a barbecue pit.’ Nuclear reactions are smoldering again at Chernobyl https://www.sciencemag.org/news/2021/05/nuclear-reactions-reawaken-chernobyl-reactor
By Richard Stone, May. 5, 2021 , Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world’s worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. “It’s like the embers in a barbecue pit,” says Neil Hyatt, a nuclear materials chemist at the University of Sheffield. Now, Ukrainian scientists are scrambling to determine whether the reactions will wink out on their own—or require extraordinary interventions to avert another accident.
Sensors are tracking a rising number of neutrons, a signal of fission, streaming from one inaccessible room, Anatolii Doroshenko of the Institute for Safety Problems of Nuclear Power Plants (ISPNPP) in Kyiv, Ukraine, reported last week during discussions about dismantling the reactor. “There are many uncertainties,” says ISPNPP’s Maxim Saveliev. “But we can’t rule out the possibility of [an] accident.”
The neutron counts are rising slowly, Saveliev says, suggesting managers still have a few years to figure out how to stifle the threat. Any remedy he and his colleagues come up with will be of keen interest to Japan, which is coping with the aftermath of its own nuclear disaster 10 years ago at Fukushima, Hyatt notes. “It’s a similar magnitude of hazard.”
The specter of self-sustaining fission, or criticality, in the nuclear ruins has long haunted Chernobyl. When part of the Unit Four reactor’s core melted down on 26 April 1986, uranium fuel rods, their zirconium cladding, graphite control rods, and sand dumped on the core to try to extinguish the fire melted together into a lava. It flowed into the reactor hall’s basement rooms and hardened into formations called fuel-containing materials (FCMs), which are laden with about 170 tons of irradiated uranium—95% of the original fuel.
The concrete-and-steel sarcophagus called the Shelter, erected 1 year after the accident to house Unit Four’s remains, allowed rainwater to seep in. Because water slows, or moderates, neutrons and thus enhances their odds of striking and splitting uranium nuclei, heavy rains would sometimes send neutron counts soaring. After a downpour in June 1990, a “stalker”—a scientist at Chernobyl who risks radiation exposure to venture into the damaged reactor hall—dashed in and sprayed gadolinium nitrate solution, which absorbs neutrons, on an FCM that he and his colleagues feared might go critical. Several years later, the plant installed gadolinium nitrate sprinklers in the Shelter’s roof. But the spray can’t effectively penetrate some basement rooms.
Chernobyl officials presumed any criticality risk would fade when the massive New Safe Confinement (NSC) was slid over the Shelter in November 2016. The €1.5 billion structure was meant to seal off the Shelter so it could be stabilized and eventually dismantled. The NSC also keeps out the rain, and ever since its emplacement, neutron counts in most areas in the Shelter have been stable or are declining.
But they began to edge up in a few spots, nearly doubling over 4 years in room 305/2, which contains tons of FCMs buried under debris. ISPNPP modeling suggests the drying of the fuel is somehow making neutrons ricocheting through it more, rather than less, effective at splitting uranium nuclei. “It’s believable and plausible data,” Hyatt says. “It’s just not clear what the mechanism might be.”
The threat can’t be ignored. As water continues to recede, the fear is that “the fission reaction accelerates exponentially,” Hyatt says, leading to “an uncontrolled release of nuclear energy.” There’s no chance of a repeat of 1986, when the explosion and fire sent a radioactive cloud over Europe. A runaway fission reaction in an FCM could sputter out after heat from fission boils off the remaining water. Still, Saveliev notes, although any explosive reaction would be contained, it could threaten to bring down unstable parts of the rickety Shelter, filling the NSC with radioactive dust.
Addressing the newly unmasked threat is a daunting challenge. Radiation levels in 305/2 preclude getting close enough to install sensors. And spraying gadolinium nitrate on the nuclear debris there is not an option, as it’s entombed under concrete. One idea is to develop a robot that can withstand the intense radiation for long enough to drill holes in the FCMs and insert boron cylinders, which would function like control rods and sop up neutrons. In the meantime, ISPNPP intends to step up monitoring of two other areas where FCMs have the potential to go critical.
The resurgent fission reactions are not the only challenge facing Chernobyl’s keepers. Besieged by intense radiation and high humidity, the FCMs are disintegrating—spawning even more radioactive dust that complicates plans to dismantle the Shelter. Early on, an FCM formation called the Elephant’s Foot was so hard scientists had to use a Kalashnikov rifle to shear off a chunk for analysis. “Now it more or less has the consistency of sand,” Saveliev says.
Ukraine has long intended to remove the FCMs and store them in a geological repository. By September, with help from European Bank for Reconstruction and Development, it aims to have a comprehensive plan for doing so. But with life still flickering within the Shelter, it may be harder than ever to bury the reactor’s restless remains.
A drone pierced the outer shell of Ukraine’s Chernobyl nuclear plant. Radiation levels are normal

AP News 14th Feb 2025
CHERNOBYL NUCLEAR POWER STATION, Ukraine (AP) — A drone armed with a warhead hit the protective outer shell of Ukraine’s Chernobyl nuclear plant early Friday, punching a hole in the structure and briefly starting a fire, in an attack Kyiv blamed on Russia. The Kremlin denied it was responsible.
Radiation levels at the shuttered plant in the Kyiv region — site of the world’s worst nuclear accident — have not increased, according to the U.N. International Atomic Energy Agency, which said the strike did not breach the plant’s inner containment shell.
The IAEA did not attribute blame, saying only that its team stationed at the site heard an explosion and was informed that a drone had struck the shell.
Fighting around nuclear power plants has repeatedly raised fears of a nuclear catastrophe during three years of war, particularly in a country where many vividly remember the 1986 Chernobyl disaster, which killed at least 30 people and spewed radioactive fallout over much of the Northern Hemisphere.
The Zaporizhzhia nuclear power plant, which is Europe’s biggest, has occasionally been hit by drones during the war without causing significant damage……………………………………………………………………
Kremlin spokesman Dmitry Peskov denied Russia was responsible. “There is no talk about strikes on nuclear infrastructure, nuclear energy facilities. Any such claim isn’t true. Our military doesn’t do that,” Peskov said in a conference call with reporters.
It was not possible to independently confirm who was behind the strike. Both sides frequently trade blame when nuclear sites come under attack. https://apnews.com/article/russia-ukraine-war-chernobyl-zelenskyy-71d781dbd66754d0a548edd388f3447a
‘Deeply Concerned’ Dems Want to Know If DOGE Can Access Nuclear Weapons Data
Common Dreams, Brett Wilkins, 12 Feb 25
“The nation and the world need to know that U.S. nuclear secrets are robustly safeguarded,” argue Sen. Ed Markey and Rep. Don Beyer.
A pair of Democratic U.S. lawmakers on Wednesday asked the Trump administration to clarify whether any members of Elon Musk’s Department of Government Efficiency have access to classified information about the nation’s nuclear arsenal.
Responding to U.S. Energy Secretary Chris Wright’s admission that he granted DOGE associates access to the Department of Energy, and to reporting that a 23-year-old former intern at Musk’s SpaceX was allowed into DOE’s IT systems without the requisite security clearances, Sen. Ed Markey (D-Mass.) and Rep. Don Beyer (D-Va.)—both members of the congressional Nuclear Weapons and Arms Control Working Group—wrote to Wright to voice their concerns.
“The National Nuclear Security Administration (NNSA), an integral part of the Department of Energy, is entrusted with protecting the nation’s most sensitive nuclear weapons secrets. The nation and the world need to know that U.S. nuclear secrets are robustly safeguarded,” the lawmakers wrote.
“It is, therefore, dangerously unacceptable that Elon Musk’s Department of Government Efficiency—including individuals lacking adequate security clearances—has been granted access to DOE’s information technology (IT) system despite legitimate security concerns inside the agency,” they added………………………………………………… more https://www.commondreams.org/news/doge-nuclear-access?fbclid=IwY2xjawIbZXRleHRuA2FlbQIxMQABHbA6z6FjvC4GlquaoKQ8r8aITLOLFc__JZxKMtuKaj69sCBrQ9lN5_mJ_A_aem_azkG9HYTMg9NxlbYp67XYA
