Luck is not a safety plan

“We must act now,” said International Atomic Energy Agency director general, Rafael Grossi. But what is his plan? IAEA efforts at creating a “safe zone” around the Zaporizhzhia reactors, where no fighting could then occur, have collapsed. On the geopolitical stage, both Russia and Ukraine appear to harbor the conviction that their side can win the war.

War devastation is bad enough without adding a nuclear disaster

Luck is not a safety plan — Beyond Nuclear International

How much more perilous can the situation at Zaporizhzhia nuclear power plant become?

By Linda Pentz Gunter, 14 May 23

Luck is not a sound basis on which to rely when we are dealing with nuclear risks. But luck is again what me must depend on as we watch and wait for the worst to happen — or not — at the six-reactor Zaporizhzhia nuclear power plant in Ukraine.

The plant, located in the southwestern region of the country — the area most directly embroiled in some of the most intense fighting, and with parts of it already “annexed” by Russia — has already experienced some frightening near-misses. These include shelling and missile attacks and frequent losses of offsite power that, if not restored promptly, could lead to a meltdown.

The plant has been occupied by Russian forces since March 4, 2022. Rumors abound that a severely depleted workforce is laboring under stressful and even violent conditions, while other staff have fled or have disappeared.

Now we learn that mass evacuations are underway from communities close to the nuclear plant. These include residents of Enerhodar, the city that houses most of the plant workers and their families……………………….

Fears of a Ukrainian offensive designed to recapture some or all of the Russian-held territory appear to have prompted the sudden evacuation. But are people evacuating away from the conflict or from the prospect of a catastrophic outcome at the nuclear power plant, should it become fully engulfed by the fighting? And if that does happen, what might the consequences be?

As a precaution, all six Zaporizhzhia reactors are currently shut down — officially their status is called “cold shutdown”, which is not as final as it sounds and does not mean they are out of danger. 

The fuel in the reactor core still requires electricity to power cooling, as do the pumps that supply cooling water to the fuel pools. This means a meltdown is still possible. Cold shutdown just buys workers more time to restore power should it become lost, but a reliable supply of electricity to the site is still essential to avoid disaster…………

The consequences of such an outcome would be drastic not only for the people of Ukraine and neighboring Russia, but for all of Europe, should any or all of these reactors melt down or suffer a fuel pool fire. We only have to look at the fallout map from the 1986 Chornobyl disaster, a single unit with a far smaller radioactive inventory, to understand the potential scale of such a tragedy.

Chornobyl contaminated 40% of the European landmass with long-lived radioactive fallout and created an effectively permanent 1,000 square mile Exclusion Zone around the stricken nuclear site. 

Beyond electrical power, water supply is also essential to keep nuclear power plants out of danger. The thermally and radioactively “hot” irradiated fuel rods sitting in cooling pools, must stay submerged. Electrically powered pumps can maintain a steady water supply. But access to water is critical.

In late March, alarms were raised about a dramatic drop in water levels at the reservoir that supplies cooling water to the plant. Ukrainian officials said the Russians had drained the reservoir, increasing the risk of a meltdown at Zaporizhzhia.

But this month, headlines warned that record high water levels could threaten a dam that, if breached, would send floodwaters pouring onto the nuclear site, inundating the plant’s pumping systems.

War, flooding, and human error are all potential disasters waiting in the wings that could trigger a nuclear catastrophe. But what can prevent it?

“We must act now,” said International Atomic Energy Agency director general, Rafael Grossi. But what is his plan? IAEA efforts at creating a “safe zone” around the Zaporizhzhia reactors, where no fighting could then occur, have collapsed. On the geopolitical stage, both Russia and Ukraine appear to harbor the conviction that their side can win the war. NATO and its allies show no signs of insisting on a diplomatic solution, given the benefit to those countries of a Russian defeat.

All of this brutality already comes at immense cost to the population of Ukraine, but also to Russia, where mothers, too, are losing sons to an unnecessary war. A major strike on Europe’s largest nuclear power plant would extend that tragedy across thousands of miles, affecting hundreds of millions of lives. All we’ve got between us and that disaster is luck, which, like the deadly uranium that fuels nuclear power plants, will eventually run out.

Risks too high at Zaporizhzhia

May 10, 2023  https://beyondnuclear.org/risks-too-high-at-zaporizhzhia/

Beyond Nuclear has put out a press statement warning that the risks of a nuclear catastrophe at Ukraine’s six-reactor Zaporizhzhia nuclear power plant are too high, with rumors of a Ukrainian offensive reportedly prompting mass evacuations of civilians living near the plant. Only an immediate ceasefire — or, better still, a negotiated end to a likely unwinnable war — can protect us from a potentially catastrophic nuclear incident at the plant, which has already endured shelling, missile attacks, and frequent loss of connection to the electrical grid.

The press release begins:

Fears of an imminent Ukrainian offensive that could put the country’s six-reactor Zaporizhzhia nuclear power plant in even greater danger, should prompt immediate efforts to negotiate a ceasefire, if not an end to the Russian war against Ukraine, urged safe energy group, Beyond Nuclear today.

News reports that civilians around the Zaporizhzhia nuclear power plant are being evacuated suggest that the conflict already consuming the southwestern region of Ukraine could be about to escalate, potentially engulfing the nuclear plant.

The Zaporizhzhia nuclear power plant has already escaped close calls, the target of shelling and missile attacks on at least one occasion and with frequent losses of offsite power that, if not restored promptly, could lead to a meltdown. 

The plant has been occupied by Russian forces since March 4, 2022. Rumors abound that a severely depleted workforce is laboring under stressful and even violent conditions, while other staff have fled or have disappeared.

As a precaution, all six Zaporizhzhia reactors are currently shut down, but that does not mean they are out of danger. 

“The fuel in the reactor core still requires electricity to power cooling, as do the pumps that supply cooling water to the fuel pools,” warned Beyond Nuclear international specialist, Linda Pentz Gunter. “A meltdown is still possible. Putting the reactors in what is termed ‘cold shutdown’ just buys workers more time to restore power, but a reliable supply of electricity to the site is still essential to avoid disaster.

“The consequences not only for the people of Ukraine and neighboring Russia, but for all of Europe, should any or all of these reactors melt down or suffer a fuel pool fire are unimaginably dire,” Pentz Gunter said.

Zaporizhzhia nuclear plant facing ‘catastrophic’ staff shortage amid Russian evacuation

Russia plans to relocate thousands of staff from nuclear plant, atomic energy company claims, warning of ‘catastrophic lack of qualified personnel’

Associated Press, 11 May 23

Russia plans to relocate about 2,700 Ukrainian staff from Europe’s largest nuclear plant, Ukraine’s atomic energy company has claimed, warning of a potential “catastrophic lack of qualified personnel” at the Zaporizhzhia facility in Russian-occupied southern Ukraine.

Workers who signed employment contracts with Russia’s nuclear agency Rosatom following Moscow’s capture of the Zaporizhzhia plant early in the war are set to be taken to Russia along with their families, Energoatom said in a Telegram post on Wednesday.

The company did not specify whether the employees would be forcibly moved out of the plant, nor was it immediately possible to verify Energoatom’s claims about Moscow’s plan.

Removing staff would “exacerbate the already extremely urgent issue” of staff shortages, Energoatom said.

The Moscow-installed governor of the region ordered civilian evacuations from the area last Saturday, including from the nearby city of Enerhodar where most plant workers live. The full scope of the evacuation order was not clear.

Russian forces seized the Zaporizhzhia plant days after Russian president, Vladimir Putin, ordered the invasion of Ukraine in February 2022. Russian occupiers left the Ukrainian staff in place to keep the plant running but the exact number of workers currently at the plant is not known.

Fighting near the plant has fuelled fears of a potential catastrophic incident like the one at Chornobyl, in northern Ukraine, where a reactor exploded in 1986 and contaminated a vast area in the world’s worst nuclear accident.

Zaporizhzhia is one of the 10 biggest nuclear plants in the world. While its six reactors have been shut down for months, it still needs power and qualified staff to operate crucial cooling systems and other safety features…………………. more https://www.theguardian.com/world/2023/may/11/zaporizhzhia-nuclear-plant-facing-catastrophic-staff-shortage-amid-russian-evacuation

Ukraine war: ‘Mad panic’ as Russia evacuates town near Zaporizhzhia plant

BBC 8 May 23

Russia has sparked a “mad panic” as it evacuates a town near the contested Zaporizhzhia nuclear power plant, a Ukrainian official says.

Russia has told people to leave 18 settlements in the Zaporizhzhia region, including Enerhodar near the plant, ahead of Kyiv’s anticipated offensive.

The Ukrainian mayor of Melitopol, Ivan Fedorov, said there were five-hour waits as thousands of cars left.

The UN’s nuclear watchdog warned a “severe nuclear accident” could occur.

Speaking to the BBC’s Newshour programme Rafael Grossi – the director of the International Atomic Energy Agency (IAEA) – said the evacuation of residents near the nuclear facility indicated the possibility of heavy fighting between Russian and Ukrainian forces around the plant.

Although its reactors were not producing electricity they were still loaded with nuclear material, he said.

Mr Grossi added that he had had to travel through a minefield when he visited the plant a few weeks ago.

Earlier, the IAEA warned in a statement that situation at the Zaporizhzhia facility was “becoming increasingly unpredictable and potentially dangerous”.

Operating staff were still at the site but there was “deep concern about the increasingly tense, stressful, and challenging conditions for personnel and their families”.

It said IAEA experts at the plant had “received information that the announced evacuation of residents from the nearby town of Enerhodar – where most plant staff live – has started”.

On Friday, the Russian-installed regional head Yevgeny Balitsky said that “in the past few days, the enemy has stepped up shelling of settlements close to the front line”.

“I have therefore made a decision to evacuate first of all children and parents, elderly people, disabled people and hospital patients,” he wrote on social media. .

The IAEA has issued warnings previously about safety at the plant – which Russia captured in the opening days of its invasion last year – after shelling caused temporary power cuts.

In March the IAEA warned the plant was running on diesel generators to keep vital cooling systems going, after damage to power lines.

Since Russia launched its invasion in February 2022 the number of staff at the plant has declined, the IAEA says, “but site management has stated that it has remained sufficient for the safe operation of the plant”.

Russian forces occupy much of the Zaporizhzhia region but not the regional capital Zaporizhzhia, which lies just north-east of Enerhodar across the Dnipro reservoir.

On Sunday, the Ukrainian general staff said civilians were being evacuated to the cities of Berdyansk and Prymorsk, further inside Russian-held territory……………………….. https://www.bbc.com/news/world-europe-65515443

Disaster Fears After Explosives Found Inside Zaporizhzhia Nuclear Plant

NewsWeek, BY BRENDAN COLE ON 5/4/23

Observers from the United Nations nuclear energy watchdog have found explosives inside Zaporizhzhia Nuclear Power Plant, Ukrainian media has reported.

A small team from the International Atomic Energy Agency (IAEA) is at the nuclear plant, which is Europe’s biggest and was seized by Moscow early in its invasion of Ukraine.

Operated by Ukrainian staff working under Russian forces and the Russian nuclear company Rosatom, the hostilities at the site, in which both sides accused the other of shelling, have sparked international alarm at what might happen if the reactors were impacted.

Operated by Ukrainian staff working under Russian forces and the Russian nuclear company Rosatom, the hostilities at the site, in which both sides accused the other of shelling, have sparked international alarm at what might happen if the reactors were impacted.

……………………………… Mark Nelson, an adviser on nuclear energy, said that the sites’ reactors were close together but have independent safety features. “Even the Chernobyl blast at Reactor 4 in 1986 did not prevent Reactor 3 from continuing to run and indeed sharing a turbine building until 2000,” he said.  https://www.newsweek.com/russia-ukraine-nuclear-zaporizhzhia-iaea-explosives-1798382

This week, Ukraine’s nuclear operator Energoatom said that Russian-installed managers at the plant were trying to leave the site in south-eastern Ukraine over concerns about Kyiv’s anticipated counteroffensive.

Newsweek has emailed Energoatom and the Russian defense ministry for comment.

Record high water levels threaten dam near Zaporizhzhia nuclear plant.

Dam water threat near Ukraine nuclear plant: Russia By David Ljunggren, May 5 2023  https://www.canberratimes.com.au/story/8184463/dam-water-threat-near-ukraine-nuclear-plant-russia/

Record high water levels could overwhelm a major dam in southern Ukraine and damage parts of the Russian-controlled Zaporizhzhia nuclear power station, a Russian official has told Tass agency.

Renat Karchaa, an adviser to the general director of nuclear energy firm Rosenergoatom, said if the Nova Kakhovka dam did rupture, the power cable line for the Zaporizhzhia plant’s pumping stations would be flooded.

“This (would create) functional problems for the operation of the plant and risks for nuclear safety,” he told Tass.

Last November, after Russian forces withdrew from the nearby southern Ukrainian city of Kherson, satellite imagery showed significant new damage to the dam.

Both sides have accused each other of planning to breach the dam using explosives, which would flood much of the area downstream and would likely cause major destruction around Kherson.

Karchaa’s comments represent a significant contrast from those made in late March by Ukrainian officials, who said they feared the Zaporizhzhia facility could face a shortage of water to cool reactors by late summer because Russian forces had let water out of a reservoir that supplied the plant.

Russian troops took over the plant as they invaded parts of Ukraine last year.

It is at the centre of a nuclear security crisis due to near-constant shelling in its vicinity which Kyiv and Moscow blame on each other.

Zaporizhzhya Nuclear Power Plant: a Catastrophe Waiting to Happen

BY CAROL WOLMAN CounterPunch 1 May 23

A meltdown at Zaporizhzhya Nuclear Power Plant grows more likely with every passing day.  With a meltdown, radioactive water from the plant would flow into the Dnieper River, which empties into the Black Sea, and thence to the Mediterranean.  See below for map.   The consequences would be catastrophic for Europe, North Africa, and the Middle East.  Clearly this is an international problem.  It calls out for an international solution.

Perhaps it is time to send in UN Peacekeeping Forces.

ZNPP has been at risk for a Fukushima-type meltdown since the Russians occupied the plant in March 2022.  It sits on the front line of the war, the south side of the Dnieper River.   The Russians quickly occupied the south side early in their invasion; the Ukrainians still occupy the north side.

The International Atomic Energy Agency was able to establish a presence at ZNPP after months of lobbying by its Director- General Mariano Grossi.  He has personally visited twice and gets daily updates from the IAEA personnel on site.  His latest report can be found here.

Grossi has been trying for almost a year to negotiate a safety zone around ZNPP.  After his visit to the plant on 3/29/23, Grossi stressed that the increasing combat makes it urgent to find a way to prevent a potentially catastrophic nuclear accident.

He complains that he is not getting support from the UN, and even from his own agency.   The EU issued a statement a few months ago but is not keeping the pressure on.  Given the potential for catastrophe, it is astounding that more attention is not being given to the need to support Grossi’s efforts.

Instead, the media publishes reassuring articles about how many safety features ZNPP has.

Safety features are useless if the cooling water stops circulating around the nuclear material.  The reactors have been shut down, so the pumps need an external power source.

The main power lines cross the Dnieper to the Ukraine energy grid on the north side of the river.  The back up lines connect to conventionally fired plants in Ukrainian territory.  They are right on the front line, and mortar fire from either side can cut them.

Since the invasion, all the external power lines to the plant- 4 major lines and 2-4 backup lines- have been cut simultaneously at least SIX times, forcing the pumps to rely on emergency diesel generators.  As Grossi says ““Each time we are rolling a dice…And if we allow this to continue time after time, then one day our luck will run out.”

Without the constant circulation of cooling water, the nuclear fuel would overheat, resulting in a chain reaction and meltdown.   This is what happened at Fukushima Daiichi 1:

; the earthquake and tsunami cut off the power and the pumps stopped working.  A huge discharge of radioactive water into the vast Pacific Ocean continued for several years, until an ice wall was built around the damaged reactors.

Within three years after the Fukushima disaster, there were massive die-offs throughout the Pacific.  Mollusks in particular suffered, and the result went up the food chain, so that sea mammals were starving and mutated.  The sea bird population was decimated.

A meltdown at ZNPP would release large amounts of radioactive water into a much smaller body of water than the Pacific Ocean.  The Dnieper River empties into the Black Sea and eventually into the Mediterranean.  All the countries which border the Mediterranean would be affected.  The consequences are unthinkable.

The circulation of cooling water could fail for another reason.  It cycles through a holding pond nearby.  Because of the constant influx of warm water from the reactors, still hot even in shutdown mode, the pond is prone to algae growth, which could clog the intake valves and stop the water flow.  It is stocked with tropical fish, which eat the algae and keep the water clear.

The cooling pond is at risk. Global warming may cause the pond to overheat this summer, killing the scavenging fish…………………………………………………

Clearly this is an international problem.  The danger of a meltdown at ZNPP is real; the consequences would be catastrophic for Europe, North Africa, and the Middle East……………………………………………………………..  https://www.counterpunch.org/2023/05/01/znpp-a-catastrophe-waiting-to-happen/

Russia fixing power line from Zaporizhzhia nuclear plant to land it controls, IAEA says

VIENNA, April 28 (Reuters) https://www.reuters.com/world/europe/russia-fixing-power-line-zaporizhzhia-nuclear-plant-land-it-controls-iaea-says-2023-04-28/– Russia has informed the U.N. nuclear watchdog that equipment spotted at Ukraine’s Zaporizhzhia nuclear power plant, which Russia controls, will be used to fix a power transmission line that leads to Russian-held territory, the watchdog said on Friday.

The planned restoration of the downed power line could heighten Ukrainian fears that Russia is preparing to connect Zaporizhzhia, Europe’s largest nuclear power plant, to the power grid of territory that it controls.

A small number of International Atomic Energy Agency officials are present at the Zaporizhzhia nuclear power plant (ZNPP), which is operated by Ukrainian staff working under the orders of Russian forces and the Russian nuclear company Rosatom.

“The (IAEA) Team observed, and following questions were subsequently informed, that a large piece of equipment being transported into the turbine hall of Unit 3 was a transformer to replace the damaged ‘Kakhovka’ node in the ZNPP open switchyard,” the IAEA said in a statement.

“The Kakhovka line is one of the four 750 kV (kilovolt) lines that were operational before the military conflict. This line is linked to the currently Russian-controlled electrical grid, to the south of the ZNPP site,” it added.

Only one of those four power lines is currently working and is the only source of external power to the plant, which it needs to keep cooling the fuel in its six reactors even though they are shut down. Failing to cool that fuel could lead to a potentially catastrophic nuclear meltdown.

The IAEA said it also had not had access to the switchyard at a nearby thermal power plant (TPP) that can supply backup power to Zaporizhzhia. The IAEA last visited that switchyard in December, when damage from shelling was observed.

“Two weeks ago the team was informed that access would be granted in the coming days. It is important that ISAMZ (the IAEA Support and Assistance Mission to Zaporizhzhia) gets the necessary access to the ZTPP open switchyard given the implications on nuclear safety and security at ZNPP.”

Chernobyl anniversary offers a bleak look at what may await other Ukrainian nuclear plants

A huge steel and concrete sarcophagus covers the site of the meltdown. Under its dome, called the New Safe Confinement, lie 200 tons of lava-like nuclear fuel, 30 tons of highly contaminated dust and 16 tons of uranium and plutonium that continue to release high levels of radiation.

April 26, 2023 by Charles Digges  https://bellona.org/news/nuclear-issues/2023-04-chernobyl-anniversar

A little over a year ago, Russian troops abandoned Chernobyl after briefly occupying it during the grim opening days of Moscow’s invasion of Ukraine. The takeover of the site where the world’s worst nuclear disaster happened thirty-seven years ago this week offered a preview of the reckless disregard for nuclear safety that has characterized so much of this war.

While the site has been left to Ukraine to painstakingly restore since the Russian withdrawal on March 31, 2022, the new anniversary of the Chernobyl plant’s original disaster on April 26, 1986, leaves lingering questions about what, exactly, the world can do when Ukraine’s nuclear infrastructure — or indeed any nuclear infrastructure — is attacked by a hostile neighbor.

The answer, at this point?  Not much — aside from trying to pick up the pieces after the damage is already done.

As it stands, the Chernobyl exclusion zone is still dotted with mines planted by Russian troops when they rolled into the territory, churning up clouds of radioactive dust with hundreds of heavily armored vehicles. The mines have made treacherous any efforts to restore the territory.

Russian troops also dug trenches and set fires in an area known as the Red Forest — a gnarled expanse of irradiated trees — and scorched, according to NASA, some 14,000 hectares of land, filling the air with so much radioactive smoke that it was unsafe for firefighters to quell the blazes.

All the while, hundreds of Chernobyl employees — who oversee the site’s sprawling network of spent fuel storage facilities as well as the enormous efforts to dismantle the radioactive remnants of the exploded No. 4 reactor — were held hostage onsite, prevented from rotating out at the end of their shifts. Five workers were kidnapped and nine were killed, according to The Washington Post.

Those who remained said later that they had tried to keep the Russians from the most dangerous areas within the plant’s territory. But in what many called the worst situation they have seen in the decades since the initial disaster, Chernobyl’s power was cut by fighting, leaving them to rely on diesel generators  for nearly a week to support the critical work of circulating water to cool spent nuclear fuel.

The damage the Russian soldiers did wasn’t purely technical. Doors to offices were ripped off hinges, windows smashed, walls spray-painted with graffiti.

“The poop was the icing on the cake,” Aleksander Barsukov, deputy director of the Chernobyl Ecocenter, which keeps samples of radioactive material collected from all over the world, told The Wall Street Journal after the Russian retreat.

By the time Russian troops pulled back from the plant on March 31, 2022 — amid reports of possible radiation poisoning among their ranks — Chernobyl’s technicians had been held at literal gunpoint at their workstations for more than a month.

During the retreat, according to Ukrainian accounts, Russian soldiers ransacked the site and took anything that looked valuable, looting more than 1,000 computers, and spiriting away dosimeters, software, lab tools, firefighting equipment — and in some cases even household appliances — piling them in stolen Ukrainian trucks.

“Whatever they didn’t steal, they broke,” Chernobyl Information Director Vitaly Medved told the BBC at the time.

Russian soldiers then brazenly mailed much of the booty home from across the Belarusian border. They also made off with radioactive instruments used to calibrate personal dosimeters for Chernobyl staff — substances that can cause radiation burns if handled improperly.

According to the European Bank of Reconstruction and Development, which has financed much of Chernobyl’s cleanup work since the original 1986 disaster, the Russian Army’s destructive adventure in the world’s most famous radioactive wasteland will cost some €100 million to repair.

The four RBMK reactors at the enormous nuclear station in Chernobyl no longer produce power, but before the invasion nearly 6,000 workers monitored the lasting effects of the disastrous meltdown that took place in 1986, as well oversaw as processing spent nuclear fuel from other plants in Ukraine. In the days before the invasion, all but a few hundred employees were evacuated.

Located just a few miles from the Belarusian border, Chernobyl was one of the first places occupied by Russian troops. Yevhen Kramarenko, the director of the exclusion zone — the  2,6000-square-kilometer area where radiation levels remain high and public access is limited — told The Washington Post that on the first day of the invasion, a Russian general presented himself as the new leader of the station, and introduced employees from Rosatom, Russia’s state nuclear corporation.

“I believe that at the time when they came,” Kramarenko told the paper, “they planned to be there permanently, they planned to take control for a long time.”

A sign of things to come?

Even before the occupation, the Chernobyl station had a post-apocalyptic air. It is situated in a dense forest, swarming with mosquitoes and gnats. Pripyat, the city where employees lived before the disaster, now stands empty and is being reconquered by nature.

A huge steel and concrete sarcophagus covers the site of the meltdown. Under its dome, called the New Safe Confinement, lie 200 tons of lava-like nuclear fuel, 30 tons of highly contaminated dust and 16 tons of uranium and plutonium that continue to release high levels of radiation.

Yet while Rosatom may have failed to keep hold of Chernobyl, the same cannot be said about Ukraine’s embattled Zaporizhzhia nuclear plant — Europe’s largest such facility — which once supplied a fifth of Ukraine’s electricity.

Since October of 2022, Moscow claims that it now controls the plant — a claim not honored by the UN’s International Atomic Energy Association, to say nothing of Kyiv.

From then on, Rosatom has begun flooding the Zaporizhzhia plant with Russian staff that it has transferred from its own Kalinin nuclear plant, 545 kilometers across the front to the northeast.

But while Russia asserts the six-reactor facility has been taken over as a protective measure, there is little to suggest that the joining of Russian and Ukrainian workforces is going smoothly.  Only about 2,000 Ukrainian staff members still work at the plant, out of 11,000 before the war.

Indeed, much of Rosatom’s effort to assert itself at the plant has involved arresting and torturing Ukrainian workers opposed to the occupation as it toils to link Zaporizhzhia with the Russian electricity grid.

The plant, which lies on the south side of the Dnipro River next to the nuclear plant’s home city of Enerhodar, is on the front line of the war. Ukrainian troops are just a few of kilometers to the north, on the far bank of the Dnipro, while Russians are holed up in the power plant.Anxieties are high that the area could see renewed fighting in any Ukrainian counteroffensive.

Ukraine accuses the Russians of using the plant as a shield, hoping that the danger of causing a nuclear accident will keep Ukrainian soldiers from firing on them — the first time an atomic reactor has been put in such a position.

“They know Ukrainian troops would not dare to fire back. The nuclear power plant is a perfect hiding place from Ukrainian artillery,” Oleksiy Melnychuk, a former worker at the plant who fled from Enerhodar last July to Ukrainian-held territory, told Politico.eu. The Russians in turn accuse the Ukrainians of ignoring safety protocols and firing on areas near the plant.

The IAEA has inspectors on site and has been trying to walk a diplomatic tightrope to establish a non-military safety zone around the plant. While Moscow says it is keen to do so, Kyiv is leery of any step that could lend legitimacy to the Russian occupation.

Late last month, IAEA chief Rafael Mariano Grossi dropped the idea, and instead is now pushing for both sides to take steps to ensure that the plant isn’t attacked.

Over the last year, four of the station’s six VVER reactors have been put into a cold shutdown to minimize the risk of an accident, while two have been restarted to produce low levels of power to keep the plant operational. The facility needs access to electricity to ensure reactor cooling and other safety functions. However, its links to the Ukrainian grid have been cut six times since last March, forcing the ZNPP to rely on diesel-powered generators for emergency backup power — a situation that IAEA Director General Rafael Grossi has referred to as “rolling the dice.”

“And if we allow this to continue time after time then one day our luck will run out,” he added.

Still, even as events deteriorate, there is little the world can do but watch.

Even Grossi — who heads the world’s most respected nuclear power diplomacy body — has admitted as much. During a meeting of the IAEA’s  35-member board of governors last month, Grossi castigated his colleagues for “complacency” after the latest spate of airstrikes had again cut off Zaporizhzhia’s access to grid electricity.

“What are we doing to prevent this [from] happening?“ a flabbergasted Grossi asked the board. ”We are the IAEA, we are meant to care about nuclear safety.”

Even so, aspirations of pushing out the Russians among plant workers remain high.

“We still hope de-occupation is possible,” Melnychuk told Politico.eu. “You can’t even imagine how ready we all are to return and let our colleagues, working under tremendous pressure and fear, to finally have some rest.”

Unfortunately, the state of Chernobyl offers the clearest glimpse of what they may find if — or when — that time comes.
