The RITM-200 is an integrated generation 3+ pressurized water reactor developed by OKBM Afrikantov and designed to produce 55 MWe. The design is an improvement of KLT-40 reactor. It uses up to 20% enriched uranium-235 and can be refueled every 10 years for a 60 year planned lifespan in floating power plant installation.^[1] If installed in a stationary power plant the fuel cycle is 6 years.

The RITM-200 has a compact integrated layout placing equipment within the steam generator casing, halving system weight compared to earlier designs and improving ability to operate in rolling and pitching seas.^[2]

It powers Project 22220 icebreakers, the first of which went critical in October 2019^[3] and entered service in 2020 and the proposed Project 23000E supercarrier.^{[citation needed]}

In November 2020 Rosatom announced plans to place a land-based RITM-200 SMR in isolated Ust-Kuyga town in Yakutia.^[4] The reactor will replace current coal and oil based electricity and heat generation at half the price.^[5]
