Floating nuclear power stations (Russian: плавучая атомная теплоэлектростанция малой мощности, ПАТЭС ММ - lit. floating combined heat and power (CHP) low-power nuclear station) are vessels designed by Rosatom.

They are self-contained, low-capacity, floating nuclear power plants. The stations are to be mass-produced at shipbuilding facilities and then towed to the destination ports of the cities and towns experiencing deficit of power due to industrialization.

The work on such projects dates back to MH-1A, which was built in the 1960s into the hull of a World War II Liberty Ship; however, the Rosatom project is the first mass-produced floating nuclear power plant. The initial plan was to manufacture at least seven of the vessels by 2015.

The modular power plant is descended from Russia's more than 6500 reactor-years with ship propulsion reactor experience. In 2000 the project for a floating power station began when the Ministry for Atomic Energy of the Russian Federation (Rosatom) chose Severodvinsk in Arkhangelsk Oblast as the construction site, Sevmash was appointed as general contractor. Construction of the first power station, the Akademik Lomonosov, started on 15 April 2007 at the Sevmash Submarine-Building Plant in Severodvinsk. However, in August 2008 construction works were transferred to the Baltic Shipyard in Saint Petersburg, which is also responsible for the construction of future vessels.Akademik Lomonosov was launched on 1 July 2010, at a cost of 6 billion rubles (232 m$). In 2015 construction of a second vessel starting in 2019 was announced by Russia’s state nuclear corporation Rosatom.

The floating nuclear power station is a non-self propelled vessel. It has length of 144.4 metres (474 ft), width of 30 metres (98 ft), height of 10 metres (33 ft), and draught of 5.6 metres (18 ft). The vessel has a displacement of 21,500 tonnes and a crew of 69 people.
