Mayak is a Soviet-era plutonium production and nuclear materials complex near Ozyorsk in Chelyabinsk Oblast, Russia. It was built in secrecy between 1945 and 1948 and was organized as the Mayak Production Association in 1948.

Its first plutonium production reactor, Reactor A, began operation on June 19, 1948, and supplied material for the first Soviet nuclear weapon test in 1949. Between 1949 and 1951, radioactive waste was discharged into the Techa River, and from 1951 Lake Karachay was used as a waste basin. On September 29, 1957, a cooling-system failure caused a chemical explosion in a waste storage tank (the Kyshtym disaster), rated level 6 on the International Nuclear Event Scale.
