UN: Ukrainian Nuclear Plant "Extremely Vulnerable" After Power Outages; Russia Taking Control

The Zaporizhzhia Nuclear Power Plant in Ukraine lost external power seven times, relying on emergency generators that can fail, the IAEA chief warns.
Russia has occupied the plant, Europe's largest, and cut off its power, threatening catastrophic radiation release.
All six reactors are shut down but cooling systems need power to prevent meltdown; fighting nearby heightens the danger.
Russia is sending more forces to the site, mining the area, and planning to evacuate Russian staff in a takeover of operations.
The IAEA seeks a safe zone around the plant and end to fighting to ensure safety but Russia keeps destabilizing the situation.
