Critical Update: IAEA Director General on Ukraine Nuclear Facilities

Nuclear Safety Imperiled: International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi has issued a critical update expressing deep concern over the increasing military activity around Ukraine’s nuclear facilities. For nearly three years, the IAEA has maintained a continuous presence at the Zaporizhzhya Nuclear Power Plant (ZNPP), with teams regularly reporting on military actions and air raid alarms affecting ZNPP and other Ukrainian nuclear power plants. The situation presents escalating risks to nuclear safety and security, demanding immediate attention and mitigation strategies.

Escalating Military Activity: A Clear and Present Danger

Director General Grossi’s update underscores the precariousness of the situation at Ukraine’s nuclear facilities, particularly the ZNPP. The IAEA teams, consistently present at the plant, have observed a marked increase in military activities, including drone operations, in close proximity to the site. These activities heighten the risk of damage to critical infrastructure and could potentially trigger a nuclear incident. The IAEA’s ongoing monitoring and reporting are crucial for maintaining awareness and facilitating international efforts to ensure nuclear safety.

The Cooling Water Channel: A Critical Vulnerability

A significant concern highlighted by Director General Grossi is the construction of a new dam intended to isolate one of ZNPP’s channels from its cooling pond. This channel serves a vital function, supplying cooling water to several plant systems, including unit transformers essential for the operation of safety systems. According to the IAEA report, the potential depletion of water in this channel, and the resulting loss of cooling, represents a severe nuclear safety risk. The IAEA teams are actively monitoring the situation and seeking access to investigate the construction and its potential impact. The loss of cooling could lead to a reactor meltdown, similar to the Fukushima disaster, making it imperative to safeguard this critical water supply.

Precarious External Power Supply

Adding to the vulnerabilities, the ZNPP has been operating with only a single off-site power line for over three months. This prolonged reliance on a single power source is the longest such period without a backup, making the external power supply extremely vulnerable. The IAEA has repeatedly stressed the importance of a stable and reliable power supply to ensure the safe operation of nuclear power plants. Interruption of external power can lead to a station blackout, disabling essential safety systems and increasing the risk of a nuclear accident. The prolonged absence of a backup power line significantly elevates this risk, demanding immediate action to restore redundancy.

IAEA’s Call for Restraint

Director General Grossi has consistently reiterated his call for maximum military restraint around nuclear power plants to avert a nuclear accident. The IAEA emphasizes that nuclear facilities should never be targeted or used as shields during military operations. Previous reports from the IAEA have detailed drone attacks that damaged vehicles near the ZNPP’s cooling pond and shelling incidents near the plant’s transportation department, further illustrating the ongoing threats to nuclear safety amidst the conflict. These incidents underscore the urgent need for all parties to adhere to international norms and exercise utmost caution to protect nuclear facilities from military actions.

Ongoing Monitoring and Reporting

The IAEA’s continuous presence at the ZNPP and other Ukrainian nuclear power plants is essential for providing timely and accurate information about the evolving situation. The IAEA teams regularly report on military activities, air raid alarms, and other developments that could impact nuclear safety and security. This ongoing monitoring and reporting are crucial for maintaining international awareness and facilitating coordinated efforts to mitigate risks. The IAEA’s impartial and objective assessments provide a valuable basis for informed decision-making and targeted interventions.

The Path Forward: Ensuring Nuclear Safety and Security

The situation at Ukraine’s nuclear facilities remains highly precarious, demanding sustained attention and concerted action. The IAEA’s Director General Grossi’s repeated warnings and the agency’s ongoing monitoring efforts highlight the urgent need for maximum military restraint and the protection of critical infrastructure. Addressing the vulnerabilities related to the cooling water channel and the external power supply is paramount to preventing a nuclear accident. International cooperation and adherence to international norms are essential for ensuring the safety and security of nuclear facilities amidst the ongoing conflict.
