U.N. warns of vulnerability at Ukrainian nuclear plant amidst power outages and Russian conflict.

The Zaporizhzhia Nuclear Power Plant in Ukraine, Europe's largest atomic power station, has lost its external power supply for the seventh time since Russia's full-scale invasion of Ukraine, raising concerns about the plant's safety. The head of the International Atomic Energy Agency, Rafael Grossi, has warned that the plant is "extremely vulnerable" and is planning to propose a protocol to protect it from shelling. The plant's six nuclear reactors have been shut down, but a disruption in the electrical supply could disable cooling systems that are essential for the reactors' safety. Ukraine believes the only way to secure the plant is by returning it to Ukrainian control, with IAEA inspectors present.
