Energodar, Ukraine, August 2024 – The recent fire at the Russian-occupied Zaporizhzhia nuclear power plant in eastern Ukraine has reignited international fears of a potential nuclear disaster at the war-torn facility.
The incident on August 11 has drawn renewed attention to the precarious situation surrounding the plant, which has been caught in the crossfire since Moscow captured it shortly after its 2022 invasion of Ukraine.
Conflicting Accounts and Rising Tensions
As with many incidents in the ongoing conflict, the fire at the Zaporizhzhia plant has been the subject of conflicting narratives. Ukrainian authorities claim that Russian forces deliberately set automobile tires on fire in the plant’s cooling towers, creating an illusion of danger to stoke fear and uncertainty.
In contrast, Moscow has blamed the fire on Ukrainian shelling, though it has not provided any evidence to support this claim.
Regardless of the cause, the incident has heightened concerns among international observers who worry about the safety of the facility, which is Europe’s largest nuclear power plant.
The Zaporizhzhia plant has been a focal point of anxiety for both Ukrainian and international authorities since it fell under Russian control, with fears that any damage to the plant could lead to a catastrophic nuclear disaster.
However, experts have sought to reassure the public that the likelihood of such a disaster remains low, even amidst ongoing hostilities.
Expert Reassurances Amid Fears
“There’s no possibility that the plant could explode as a result of these attacks,” said Robert E. Kelley, former chief nuclear inspector at the International Atomic Energy Agency (IAEA). “The reactors at Zaporizhzhia are designed with far more stringent safety standards than those at Chernobyl.”
Kelley emphasized that the Zaporizhzhia plant uses pressurized water reactors (PWRs), which are much safer than the Soviet-era graphite-moderated reactors used at Chernobyl. PWRs do not contain the flammable graphite that contributed to the devastating fire and radioactive release at Chernobyl in 1986.
“The Chernobyl disaster occurred when the reactor was suddenly turned to full power, causing the water in the reactor to turn to steam in a fraction of a second, resulting in a massive explosion,” Kelley explained.
“In contrast, PWRs like those at Zaporizhzhia are built inside massive concrete and steel domes designed to contain such explosions and prevent radioactive leaks.”
In addition to the robust design of the reactors, Kelley pointed out that several factors further mitigate the risk of a disaster at Zaporizhzhia. Most notably, all the reactors at the plant are currently shut down, reducing the chances of overheating or a major accident.
The International Atomic Energy Agency’s current director general, Rafael Mariano Grossi, confirmed that the recent fire had not affected nuclear safety at the plant. “There is no immediate danger to nuclear safety as a result of the incident,” Grossi stated earlier this week, urging all sides to exercise restraint in the conflict.
Power Outages and Contingency Plans
Despite the reassurances, the plant has experienced power outages during previous incidents, which are technically dangerous. Without power, nuclear reactors cannot be cooled down properly, potentially leading to overheating and even an explosion, reminiscent of what happened at Chernobyl.
However, experts maintain that the chances of such a scenario unfolding today are “essentially zero.” According to Kelley, during previous blackouts at Zaporizhzhia, electricity was diverted from other sources, including the nearby Zaporizka Coal Fired Power Plant and diesel generators. These measures have limited the chances of a critical power failure at the plant.
The Human Factor: Heroes in a War Zone
Another factor reducing the risk at Zaporizhzhia has been the continued presence of Ukrainian personnel at the plant.
Despite the facility being under Russian control, much of the original Ukrainian staff has remained in place, operating the reactors and managing the plant’s safety systems under extremely difficult conditions.
“The Ukrainian citizens forced by the Russians to stay in Zaporizhzhia and run the plant for two years should be treated as heroes,” Kelley said. “They have gone through hell to ensure the safety of this facility, and their efforts deserve recognition.”
Kelley warned against labeling these workers as collaborators, emphasizing that they should be celebrated for their dedication to preventing a nuclear disaster in such a volatile environment.
Europe’s Preparedness for a Nuclear Disaster
While the situation at Zaporizhzhia remains a cause for concern, experts believe that Europe is well-prepared to respond to any nuclear incident. Across the European Union’s 27 member states, more than 150 nuclear reactors are in operation, and each country has its own agency dedicated to nuclear preparedness.
“Coordination among European countries has significantly improved since the Fukushima disaster in 2011,” said Jan Johansson, an emergency preparedness specialist at the Swedish Radiation Safety Agency.
Johansson highlighted that nuclear safety guidelines are usually established internationally by the IAEA, while European coordination is handled by organizations such as HERCA (Heads of European Radiological Protection Competent Authorities).
“HERCA has been quite active in terms of Ukraine, working to harmonize and discuss what to do in the event of a nuclear accident,” Johansson explained.
Emergency Response Plans: A Layered Approach
In the event of a nuclear incident, response plans are designed to minimize harm to the public. According to Johansson, preparation is the most important aspect of any nuclear emergency response.
“Whatever happens, even a meltdown, will take some time before it occurs. If something goes wrong, we generally know before the actual radiation leak,” he said.
In the worst-case scenario — a nuclear explosion with radiation release — an area within a five-kilometer radius of the incident would be immediately evacuated. Citizens within a 25-kilometer radius would be alerted through alarms, sirens, and text messages, advising them to shelter indoors.
Johansson emphasized that in Sweden, homes near nuclear power plants are equipped with radio receivers that go off in case of danger, ensuring that residents receive timely warnings. Additionally, all citizens are issued iodine tablets every five years to prevent thyroid cancer in the event of radiation exposure.
“The next steps depend on the amount of radioactive material leaked and meteorological factors,” Johansson added. “We practice these procedures several times a year to ensure that our systems are effective and that authorities know what to do.”
Global Stakes in a Local Conflict
As the conflict in Ukraine drags on, the Zaporizhzhia nuclear plant remains a flashpoint in a war that has already claimed thousands of lives and displaced millions. While experts continue to downplay the likelihood of a nuclear disaster, the potential for a catastrophic event looms large, underscoring the global stakes involved in this local conflict.
For now, the international community remains on high alert, closely monitoring the situation at Zaporizhzhia and urging restraint from all parties involved. But as long as the war continues, so too will the risks surrounding Europe’s largest nuclear power plant.
