Background and Relevance of the Central Nuclear Plant in Zaporiyzhia

The Central Nuclear Plant in Zaporiyzhia, Ukraine, is the largest nuclear power station in Europe. Although it is not currently operational, it still requires energy to maintain cooling for its nuclear fuel. The plant’s six reactors are currently shut down, but the spent fuel inside must be continuously cooled to prevent overheating and potential disaster.

Recent Power Disruption

On Friday, all external power lines supplying energy to the occupied plant were cut off for several hours, according to the UN nuclear regulatory body. However, the plant’s local authorities later reported that power supply had been restored.

German Galuschenko, Ukraine’s Energy Minister, announced on Telegram that a Russian attack had left the plant without power. He stated, “The enemy struck the power line connecting the temporarily occupied (Zaporiyzhia Nuclear Power Plant) to Ukraine’s integrated electricity system.”

Response and Current Status

The plant’s electricity distribution operator confirmed that their technicians took measures to restore the power supply.

Following the disruption, the International Atomic Energy Agency (IAEA) reported that the plant had lost all external power “for the ninth time during the military conflict and first time since late 2023.”

The plant is currently operating on diesel generators, as per the IAEA’s update. The agency has repeatedly warned of the risk of a catastrophic accident at Zaporiyzhia, located near the front lines of Ukraine’s war.

Official Statements

The plant’s management, based in Russia, issued a Telegram statement claiming that high-voltage power lines had been restored.

Their statement asserted that there were no disruptions in the plant’s operations, no violations of safety procedures, and no unusual increase in background radiation levels above normal.
