What inspectors will look for at Ukraine's war-damaged Zaporizhzhia nuclear plant

Inspectors for the International Atomic Energy Agency have been to some of the world's most sensitive nuclear facilities — from North Korean reactors to Iranian uranium plants. But it all seems straightforward compared to what awaits them at the Zaporizhzhia Nuclear Power Station in southern Ukraine.

Since March, the plant has been occupied by Russian forces, and run by a skeleton crew of Ukrainian workers. When they arrive, inspectors will walk past the boarded-up hulk of the main administrative building, which was pummeled by rocket-propelled grenades . A nearby courtyard holds the charred remains in late July. In recent weeks, shells have punched through the roofs of vital support buildings, and wildfires have threatened the plant's power lines.
