Rosatom has completed the first RITM-200 reactor unit, marking a significant step in Russia's initiative to develop a fleet of floating nuclear power plants. This reactor will support energy needs in remote areas, contributing to the country's shift from fossil fuels to nuclear energy.
- 01The new RITM-200 reactor unit has a capacity of 58 MWe and is the first of two for the initial floating nuclear power plant.
- 02The floating power plants aim to provide reliable energy in remote areas, with the first unit set to power a copper mining cluster in Chukotka Autonomous Okrug.
- 03Rosatom's Akademik Lomonosov has already generated over 1.2 billion kWh of electricity since its launch in 2020.
- 04The RITM-200 reactors are designed for Arctic conditions, with a service life of 40 years and refueling intervals of 5-7 years.
- 05Rosatom plans to develop floating power units for international markets with enhanced capacities and longer service intervals.

The Machine Building division of Rosatom, Russia's state-owned nuclear energy company, has successfully completed the first RITM-200 reactor unit, which will be part of the country's pioneering floating nuclear power fleet. This reactor, with a capacity of 58 MWe, is the first of two that will be installed in the initial floating power unit, known as FPU-106, which aims to supply energy to a copper mining industrial cluster in Chukotka Autonomous Okrug. The floating power plants are designed to address energy shortages in remote areas, leveraging the proven effectiveness of the RITM-200 reactors in Arctic conditions. Notably, Rosatom's existing floating facility, the Akademik Lomonosov, has generated over 1.2 billion kWh of electricity and significantly reduced greenhouse emissions. With plans for serial production of floating nuclear plants, Rosatom aims to maintain its leadership in small-scale nuclear technologies and expand its offerings to international markets, including units with capacities of 100 MWe and longer service lives.
