Ukraine announced on Saturday that a grave risk of a nuclear accident loomed over the Zaporizhzhia nuclear plant after two critical power lines were severed overnight. This dramatic development placed the plant in a perilous situation, relying on diesel generators for emergency power.

Restoration of Power Lines Averts Disaster

Kyiv’s nuclear operator reported that the plant switched to powering its own needs from 20 diesel generators due to the complete blackout. Fortunately, the power lines were restored later, preventing a possible nuclear catastrophe. The energy ministry confirmed that power to the plant, which had been occupied by Russia since March 2022, was restored on Saturday.

Plant’s Fragile State Amidst Conflict

The Zaporizhzhia nuclear power plant, no longer generating power since the Russian occupation, requires a continuous electricity supply to cool one of its four reactors in ‘hot conservation’. The last 750 kW line was disconnected early Saturday, raising alarms over the plant’s stability.

Critical Response to Power Disruption

The ministry stated that the plant’s 20 backup generators were activated following the loss of grid connection. Ukrainian specialists worked tirelessly, successfully repairing the 750 kW line by 7 a.m. (0500 GMT), thus restoring power to the plant and averting a major nuclear crisis.

Ongoing Concerns for Nuclear Safety

This incident marks the eighth blackout at the Zaporizhzhia plant, each time inching dangerously close to a nuclear catastrophe. The swift response and restoration of power this time highlight the ongoing challenges and high stakes in maintaining nuclear safety amidst the Russia-Ukraine conflict.

The near-crisis at Ukraine’s Zaporizhzhia nuclear plant underscores the fragility of nuclear facilities in conflict zones and the importance of robust emergency response mechanisms.
