The atomic icebreaker Sibir ( Russian Сибирь , Siberia) was a Russian nuclear-powered icebreaker of the Arktika- class , which was designed to keep ice-free in the northern polar region.

The ship was equipped with two OK-900A nuclear reactors, each with a thermal output of 171  MW . The reactors were in operation from 1977 to 1992. The reactors drove two steam turbines, to which in turn six generators were connected. The radiation intensity was always checked by means of sensors that were distributed over the entire ship.

In May / June 1978, the atomic icebreaker only needed 18 days to travel from Murmansk to the Bering Strait . In 1987 the Sibir embarked on a voyage that was unique in the history of Arctic seafaring: first, members of the Russian research station North Pole-27 were picked up by a drifting ice floe, then the station North Pole-29 opened and then the North Pole was reached for research purposes.

The Sibir has been out of service since 1993. All fuel elements have been removed. At the end of 2016 it was announced that the Sibir will be towed to Murmansk and will be scrapped there by the Nerpa shipyard from the beginning of 2017.
