Akademik Lomonosov  is a non-self-propelled power barge that operates as the first Russian floating nuclear power station. The ship was named after Academician Mikhail Lomonosov.

Akademik Lomonosov has a length of 144 metres (472 ft) and width of 30 metres (98 ft). It has a displacement of 21,500 tonnes and a crew of 69 people.

For the power generation, it has two modified KLT-40 naval propulsion reactors together providing up to 70 MW of electricity or 300 MW of heat. Reactors were designed by OKBM Afrikantov and assembled by Nizhniy Novgorod Research and Development Institute Atomenergoproekt (both part of Atomenergoprom).

The reactor vessels were produced by Izhorskiye Zavody. The turbo-generators were supplied by Kaluga Turbine Plant. 

Construction started at the Sevmash Submarine-Building Plant in Severodvinsk. It cost 6 billion rubles ($232 million). Originally, Akademik Lomonosov was supposed to supply power to Severodvinsk town and Sevmash itself.

However, in August 2008, the Russian government approved the transfer of work from Sevmash to the Baltic Shipyard in Saint Petersburg. Akademik Lomonosov was launched on 30 June 2010. Akademik Lomonosov is deployed at Pevek, in the Chukotka region in Russia's Far East. Now, it is the world’s first floating nuclear power plant.
