Lenin (nuclear icebreaker)
''Lenin'' ((ロシア語:Ленин)) is a decommissioned Soviet nuclear-powered icebreaker. Launched in 1957, it was both the world's first nuclear-powered surface ship〔 and the first nuclear-powered civilian vessel. ''Lenin'' entered operation in 1959 and worked clearing sea routes for cargo ships along Russia's northern coast. From 1960 to 1965 the ship covered over 85,000 miles during the Arctic navigation season, of which almost 65,000 were through ice.〔 She was officially decommissioned in 1989.〔 She was subsequently converted to a museum ship and is now permanently based at Murmansk.
==Propulsion==
In its late-1960s configuration, at full capacity the ship used five to six pounds of uranium-235 per 100 days.〔
In the later configuration (two nuclear reactors), the reactors provided steam for four steam turbines. These were connected to generators, which powered three sets of electric motors to drive the ship's three propellers.
