This WSJ podcast looks at the Chernobyl nuclear site, the place where a nuclear disaster happened in 1986. About 200 Ukraine workers are at the plant. The plant was taken over by Russian forces on the first day of the war. WSJ reporters talked to workers at the plant. To protect against the nuclear contamination a giant structure of steel and concrete was built around the plant. Since 1986 the plant is completely closed down. The job of workers is to keep the nuclear waste safe underground. This report says the 12 hour shift crew was not allowed to leave and is working for days under considerable fatigue and stress.
