The Komsomolets sank in the Norwegian Sea in 1989 after a fire on board killed 42 sailors. A sample showed radioactive caesium leaking from a ventilation pipe, but researchers said it was “not alarming”, as the Arctic water quickly diluted it. The Soviet-era sub is also deep down, at 1,680m (5,512ft), and there are few fish in the area, they added. For the first time a Norwegian remotely-operated vehicle (ROV) examined and filmed the Komsomolets on 7 July, revealing severe damage. The submarine is also known as K-278 in Russia, and it sank carrying two nuclear torpedoes with plutonium warheads.
