International Nuclear Event Scale. A representation of the INES levels. The International Nuclear and Radiological Event Scale ( INES) was introduced in 1990 [1] by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents .
The Windscale fire of 10 October 1957 was the worst nuclear accident in the United Kingdom's history, and one of the worst in the world, ranked in severity at level 5 out of 7 on the International Nuclear Event Scale. [1] The fire was in Unit 1 of the two-pile Windscale site on the north-west coast of England in Cumberland (now ...

It is one of only two nuclear energy accidents rated at seven—the maximum severity—on the International Nuclear Event Scale, the other being the 2011 Fukushima nuclear accident in Japan. The initial emergency response and subsequent mitigation efforts involved more than 500,000 personnel and cost an estimated 18 billion roubles —roughly ...

- March 28, 1979, (44 years ago)
- 04:00 (Eastern Time Zone UTC−5)
- INES Level 5 (accident with wider consequences)
The severity of the nuclear accident is provisionally rated 7 on the International Nuclear Event Scale (INES). This scale runs from 0, indicating an abnormal situation with no safety consequences, to 7, indicating an accident causing widespread contamination with serious health and environmental effects.
