Nuclear-powered icebreakers, at English Russia:

Arktika class:

They are owned by the federal government, but are operated by the Murmansk Shipping Company (MSCO). Of the ten civilian nuclear powered vessels built by Russia (and the Soviet Union), six have been of this type. They are used for clearing shipping lanes north of Siberia as well as for scientific and recreational expeditions to the Arctic.
