‘Very serious’ nuclear situation could happen ‘at any moment’ in Ukraine, says IAEA chief

Cathy Newman, Presenter 4 News 20 Aug 24

We spoke to Rafael Grossi, Director General of the International Atomic Energy Agency.

Cathy Newman: Let’s start with Zaporizhzhia, because earlier you said that safety was deteriorating there after this drone strike. How critical would you say it is?

Rafael Grossi: Well, we could have a very serious situation any moment. Because when you see the amount of military activity surrounding the plant………………………….The physical integrity of the facility is being challenged. So, this is why we say that what we see is a deterioration. The condition of the plant, I should say, is that it’s not producing energy at the moment, is in jargon what we call shut down. But there’s a lot of material there, a lot of nuclear material there. There’s a lot of spent fuel there. Fresh fuel. So, things that if impact could trigger the release of radioactivity.

Cathy Newman: So the risk has been minimised, but it hasn’t been removed, clearly. I mean, in theory, another Chernobyl is possible?

Rafael Grossi: ………………………………………… I would say, as I was just mentioning, you have all of this material around and you could have a situation theoretically where because of the loss of external power, which has occurred, we had nine episodes of complete blackouts of the plant. So no cooling function. So if you lose all that, you could eventually have a meltdown.

Cathy Newman: So it’s perilous, clearly. I wonder whether you think the risk of the Kursk plant, ……………. Russia is now fortifying around that plant. I mean, is that potentially more risky because it’s a much more volatile situation.

Rafael Grossi: It is certainly serious and we should take it very, very seriously. We are taking it, the agency at the IAEA, very, very seriously. This nuclear power plant is, I would say, within artillery range already. You have just informed that the incursion of the Ukrainian troops, is a few miles, a couple dozen kilometres into Russian territory and just a few miles, in kilometres is about between 20 and 30 km from the plant itself. And there is a technical aspect here. You were just mentioning Chernobyl. The reactors here, you have six reactors in Kursk. You have two reactors that are being decommissioned. You have two reactors that are operating. No shutdown, operating when you have hot reactors. Anything that could happen there could be maximised in this sense.

And then two other units being built. The two reactors that are operating are of a type called RBMK, which is exactly the type of reactors, an old model type of reactor was the one, like the ones that were in Chernobyl. These reactors have a particularity. Normally when you look at a nuclear reactor is a dome. There is a concrete and metal protection. These two reactors don’t have that, don’t have any of that. The core of these reactors is open. Is like, as if you were here and you could see the fuel elements there. So, God forbid, was there an impact on the plant, we could have a very serious situation…………………………………………………………………………………. https://www.channel4.com/news/very-serious-nuclear-situation-could-happen-at-any-moment-in-ukraine-says-iaea-chief

What Happens if Ukraine Seizes the Kursk Nuclear Power Plant?

Moscow Times, By Dmitry Gorchakov, Aug. 16, 2024

From the very beginning of Ukraine’s offensive into Russia’s Kursk region on Aug. 6, there has been much discussion about the possible objectives of this operation. Simply glancing at the map begs the question of whether one objective of the Ukrainian incursion might be the seizure of the Kursk nuclear plant, located just 60 kilometers from the border. 

It is a scenario the Russian side is taking seriously. Already Rosatom, Russia’s state nuclear corporation, had begun withdrawing staff from the plant and Russian troops are hastily digging trenches around it. 

The mere possibility of a nuclear plant being seized during a war is a nightmare scenario for any nuclear and radiation safety specialist. But after the almost two-and-a-half-year-long Russian occupation of the Zaporizhzhia nuclear plant and the seizures (again, by Russia) of the Chernobyl exclusion zone and the research reactor in Sevastopol during the occupation of Crimea in 2014, such scenarios have become more possible. The longer Russia’s aggression against Ukraine continues, the more common the threat of an accident will become.

While we do not know how events will unfold, our analysis at Bellona and recommendations from the IAEA make clear that should nuclear plants be enveloped by war, every effort should be made to avoid a direct assault on them with heavy weapons. The defending side should not deploy troops at nuclear plants, which would turn them into military targets. Should a nuclear plant be surrounded, it is better to surrender it through negotiations rather than have the facility be attacked or used as a staging ground for attacks. 

Having considered these principles, there are a few hypothetical plans that Ukraine could have for the Kursk nuclear plant as its incursion into Russia continues. These scenarios have repeatedly surfaced in the media, and it makes sense to address them in detail.

One theory is that Ukraine may connect the Kursk nuclear plant to its own energy system. I think this is the least likely objective. Should the plant be seized, the safest course of action for its operators would be to put all of its reactors into cold shutdown mode, which stops electricity generation……………………………………………………………..

Some have also speculated that Ukraine is trying to deprive Russia of a vital energy source — hopefully by shutting it down safely rather than a nuclear accident. But the numbers do not support this. 

One would like to believe that if such a plan exists, it does not involve the loss of the facility due to a nuclear accident, but rather involves its shutdown through standard procedures…………………………………………….

The most rational objective for seizing the Kursk nuclear plant would be to use it in exchange for the Zaporizhzhia nuclear plant in any upcoming negotiations. 

When we consider that Ukraine’s army is not only advancing in the Kursk region, but is also fortifying its position by bringing in reserves and other defenses, it appears that Kyiv intends to hold its gains — possibly until the end of the war and the start of negotiations. The presence of a nuclear power plant within the captured territory would significantly increase its leverage and would confirm the strategic nature of this operation.

Nevertheless, as a representative of an environmental organization, I sincerely hope that we do not see any attack or attempt to seize the Kursk nuclear plant. There is simply no safe way to do it. Any attempt to do so carries risks of a nuclear or radiation accident, to say nothing of damaging the political support Ukraine enjoys from its Western allies.  ………………….

 if ending this war on terms acceptable to Ukraine involves fighting around nuclear plants on both sides of the front, such a process must proceed with minimal risk of a nuclear disaster.  https://www.themoscowtimes.com/2024/08/16/what-happens-if-ukraine-seizes-the-kursk-nuclear-power-plant-a86045

Safety at Ukraine nuclear power plant deteriorating after blast, watchdog warns

The International Atomic Energy Agency said the blast was close to Zaporizhzhia nuclear power plant’s cooling water sprinkler ponds and its only remaining power line

By Brendan McFadden, iNews 17th Aug 2024

Safety at Ukraine’s Zaporizhzhia nuclear power plant is deteriorating following a drone strike that hit an access road on its perimeter, according to an atomic energy watchdog,

Russia has been in control of the Zaporizhzhia site, the largest nuclear power plant in Europe, since soon after it launched a full-scale invasion of Ukraine in February 2022.

The International Atomic Energy Agency (IAEA) said the impact site was close to the essential cooling water sprinkler ponds and about 100 m from the Dniprovska power line, the only remaining 750 kilovolt line providing a power supply to the plant.

It comes after Russia earlier claimed a Ukrainian drone dropped an explosive charge on a road used by staff.

The plant is dormant as Moscow and Kyiv have repeatedly accused each other of trying to sabotage its operations and of endangering safety around it.

The IAEA director general Rafael Mariano Grossi, said “Yet again we see an escalation of the nuclear safety and security dangers facing the power plant.

“I remain extremely concerned and reiterate my call for maximum restraint from all sides and for strict observance of the five concrete principles established for the protection of the plant.”

An IAEA team visited the area on Saturday and reported that the damage seemed to have been caused by a drone equipped with an explosive payload.

The report said there were no casualties and no impact on any nuclear power plant equipment. However, the road between the two main gates of the plant was impacted.

Moscow wants to discuss the attack on the Zaporizhzhia plant with the IAEA, Russia’s RIA news agency reported, citing Roman Ustinov, the acting Russian representative in Vienna.

The attack comes as Ukraine continues an incursion into the Kursk region of Russia.

Kyiv claims to have taken control of 82 settlements over an area of 1,150 square kilometres (444 square miles) in the region since 6 August when its advance began.

Today Ukrainian President Volodymyr Zelensky said his troops are “strengthening” positions in the captured territory in Russia and expanding further.

Russian troops also hit the Ukrainian city of Sumy with an Iskander-K cruise missile, causing extensive damage to buildings.

It was claimed Germany, Ukraine’s second biggest donor, has frozen its military aid to Kyiv because it cannot afford to any longer supply equipment due to a national budget crisis.

Meanwhile, Ukraine denied claims by Russia that it is planning to attack a nuclear plant in Kursk and use ‘dirty bombs’ to attack Russian territory,

Moscow’s defence ministry made the claim and warned there would be a harsh response to any attack on the Kursk power plant, which remains under its control, according to Russian news agency Interfax.

The ministry gave no evidence for its claim, but said the surrounding area could be contaminated by an attack on the plant………………….. https://inews.co.uk/news/world/safety-at-ukraine-nuclear-power-plant-deteriorating-after-blast-watchdog-warns-3232978

Ukraine and Russia trade accusations over fire at occupied Zaporizhzhia nuclear plant

By Reuters, August 12, 2024

• Summary

• Cause of fire unclear
• Both sides trade blame
• Main fire since extinguished
• IAEA head says attacks endanger nuclear safety, must stop

Aug 11 (Reuters) – Moscow and Kyiv accused each other of starting a fire on the grounds of Europe’s largest and now Russian-occupied Zaporizhzhia nuclear power plant in Ukraine on Sunday, with both sides reporting no sign of elevated radiation.

The U.N.’s International Atomic Energy Agency (IAEA) nuclear watchdog, which has a presence at the vast six-reactor facility, said its experts had seen strong, dark smoke coming from the northern area of the plant in southern Ukraine following multiple explosions.

“These reckless attacks endanger nuclear safety at the plant and increase the risk of a nuclear accident. They must stop now,” IAEA chief Rafael Grossi warned in a separate statement, without attributing blame for the attack.

The fire comes less than a week after Ukraine’s forces launched their largest incursion into Russian territory since the war-start in 2022, a surprise move that has brought conflict into a new phase, after weeks of Moscow’s battlefield gains.

Russian state news agencies, TASS and RIA, cited the country’s nuclear energy company Rosatom as saying the main fire was extinguished shortly before midnight on Sunday.

RIA, citing Rosatom, said a drone attack started the fire at the cooling tower, without providing evidence.

Ukraine’s nuclear power company Energoatom said in a statement on the Telegram messaging app that one of the cooling towers and other equipment were damaged………………………….Ukraine’s Energoatom said Russia’s “negligence” or arson could have sparked the fire. 

Russia’s officials in turn, including Foreign Ministry spokeswoman, Maria Zakharova, accused Kyiv of deliberately trying to destroy the plant and sow “nuclear terror………………………

Will Ukraine’s attack on Russian territory lead to the seizure of the Kursk Nuclear Plant?

Bellona, BY Dmitry Gorchakov, 9 Aug 24

As the Ukrainian army’s cross-border incursion into Russia’s Kursk Region rages into its fourth day, the objectives of the surprise attack have been grist for media speculation. Some have suggested the Ukrainians might target the Kursk Nuclear Power Plant as payback for Russia’s long-running seizure of Ukraine’s Zaporizhzhia nuclear plant.

It’s difficult to say how likely such a scenario is, but should it come to pass, it makes sense to briefly analyze the problems, risks, and dilemmas that would come of such an attack.

The specifics of the Kursk NPP

The Kursk Nuclear Power Plant is the closest Russian nuclear power plant to the Ukrainian border—just 60 km away. The idea that it could be at risk of attacks during a full-scale war became evident in the early months of Russia’s full-scale invasion of Ukraine. The Russia seizure of the Zaporizhzhia plant and territory of Chernobyl, followed by vigorous Ukrainian counterattacks, made clear that this would be a full-scale and potentially prolonged war with consequences for Russian territories.

As the war has dragged on, we have seen the Kursk NPP and its satellite city, Kurchatov, fall under attack by Ukrainian drones. No other Russian nuclear plants, which are much farther from the border and the front line, have been subjected to such attacks.

Currently, only two units are operating at the Kursk NPP, Units 3 and 4, each with a capacity of 1,000 MW. The first two units were shut down in 2021 and early 2024, respectively, after 45 years of operation. Fuel has been unloaded from Unit 1. All of the Kursk NPP’s units are RBMK-1000 reactors, similar to those used at Chernobyl. It’s worth noting that RBMK reactors — unlike the VVER-1000 reactors installed at the Zaporizhzhia NPP — are less protected against external threats. Much of our risk analysis for the Zaporizhzhia NPP during its seizure, presented in our 2023 report “The Radiation Risks of Seizing the Zaporizhzhia Nuclear Power Plant,” was based on a comparison of the characteristics of these reactor types.

Let’s examine some of the technical points and key vulnerabilities of the RBMK design. First, the lack of concrete containment structures (domes) over the reactor compartments makes RBMK reactors more vulnerable to damage from accidental or deliberate attacks by missiles, bombs, and artillery. Small arms or even light drones pose less danger.

Second, RBMK’s are single-circuit, boiling water reactors. This means that the same water and steam that pass through the reactor core go directly to the turbine, without intermediate circuits and heat exchangers. Therefore, depressurization and damage to the machine hall could lead to a radiation release………………………………

The seizure of nuclear facilities during war

Any armed seizure of a nuclear facility is unacceptable and extremely dangerous. Formally, this can be considered nuclear terrorism according to the International Convention for the Suppression of Acts of Nuclear Terrorism. Unfortunately, the reality of recent years in Europe has shown that many of the formulas embedded in international agreements, as well as many international organizations in general, are incapable of addressing, much less preventing, the modern challenges we are facing……………………………………………….   https://bellona.org/news/nuclear-issues/2024-08-will-ukraine-attacks-on-russian-territory-lead-to-the-seizure-of-the-kursk-nuclear-plant
