The International Nuclear Event Scale (INES) is a means for communicating in consistent terms the safety significance of nuclear and radiological events. Events are classified on the scale at seven levels; the upper levels (4-7) are termed 'accidents' and the lower levels (1-3) 'incidents'. The Chernobyl nuclear accident is widely regarded as the worst accident in the history of nuclear power. It is the only nuclear accident that has been classified a "major accident" by the International Atomic Energy Agency and rated 7 on the INES. The Soviet Union was also home to the second-most disastrous nuclear accident, at the Mayak Nuclear Power Plant near the city of Kyshtym, classified as a Level 6 Disaster, which is a "serious accident."
