The accident occurred on October 8, 1957, when a routine heating of the No. 1 reactor’s graphite control blocks got out of control, causing adjacent uranium cartridges to rupture. The uranium thus released began to oxidize, releasing radioactivity and causing a fire that burned for 16 hours before it was put out.

How did the Windscale fire affect the environment?
As a result, nearly 10 tons of radioactive fuel inside the reactor caught fire and burned uncontrollably for two days, polluting the atmosphere with radionuclides such as plutonium, cesium, strontium and iodine. The water that was used to extinguish the fire evaporated, adding to the radioactive emissions.
Do people still work at the Chernobyl plant?
To this day, more than 7,000 people live and work in and around the plant, and a much smaller number have returned to the surrounding villages, despite the risks.
