About Sibir

Sibir (Russian: Сибирь; literally: Siberia), built in 1977, is a retired Russian nuclear-powered icebreaker of the Arktika class. She was the only icebreaker of her class that does not feature a red superstructure. The ship was equipped with two OK-900A nuclear reactors, each producing 171 MW of thermal power. The reactors were in operation from 1977 to 1992. The reactors powered two steam turbines to which six generators were connected. The radiation intensity was always monitored using sensors distributed throughout the ship. Sibir was withdrawn from service in 1992 and was reported in 2012 as being moored at Murmansk awaiting scrapping. She had a gross tonnage of 20,655 and a dead weight of 4,096 tonnes.
