Power cut to Ukraine’s Zaporizhzhia nuclear power plant; Kyiv blames Russian strike

All external power lines supplying electricity to the Russian-occupied Zaporizhzhia Nuclear Power Plant in Ukraine were down on Friday, the UN nuclear watchdog said, and Ukraine blamed Russian shelling for severing the last power line.

Europe’s biggest nuclear power plant, which is not operating but still requires power to keep its nuclear fuel cool, has switched to running on diesel generators, the International Atomic Energy Agency said.

The IAEA has repeatedly warned of the risk of a catastrophic accident at Zaporizhzhia, which is located near the frontline in the war in Ukraine. Its six reactors are shut down, but the nuclear fuel inside them still needs to be cooled, which requires constant power.

“Ukraine’s ZNPP lost all off-site power at 17:36 today, 9th time during military conflict and first since late 2023,” the IAEA said on X. “The ZNPP currently relies on power from its emergency diesel generators, underlining (the) extremely precarious nuclear safety situation.”

Ukraine’s energy minister, German Galuschenko, wrote on Telegram that a Russian strike had cut the plant off.

“The enemy struck the power line connecting the temporarily occupied (Zaporizhzhia Nuclear Plant) with the integrated power system of Ukraine.”

Neither the IAEA nor the plant’s Russian-installed management initially cited a cause for the cut-off.

“The reasons for the disconnection are being clarified. The equipment at the station is in a safe state and under the control of staff. No violations of safety conditions have been noted,” the Russia-installed management said.
