The Andreev Bay nuclear accident took place at Soviet naval base 569 in February 1982. Andreev Bay is a radioactive waste repository 55 km northwest of Murmansk and 60 km from the Norwegian border, on the western shore of the Zapadnaya Litsa. The repository entered service in 1961. In February 1982, a nuclear accident occurred in which radioactive water was released from a pool in building #5. Cleanup of the accident took place from 1983 to 1989. About 700,000 tonnes of highly radioactive water leaked into the Barents Sea during that time. About 1,000 people took part in the cleanup effort. Vladimir Konstantinovich Bulygin, who was in charge of the naval fleet's radiation accidents, received the Hero of the Soviet Union distinction for his work.
