Sevmorput is a Russian nuclear-powered cargo ship. The 1988-built vessel is one of only four nuclear-powered merchant ships ever built and, after returning to service in 2016 following an extensive refit, the only such vessel to remain in service as of 2023.

Nuclear marine propulsion
Nuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built.
When the nuclear-powered Arktika class 50 Let Pobedy was put into service in 2007, it became the world's largest icebreaker.

In addition to nuclear-powered aircraft carriers, the United States once operated nuclear-powered cruisers.
