RITM-200
The RITM-200 is an integrated generation 3+ pressurized water reactor being developed by OKBM Afrikantov and is 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.[3] 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.[4]
It powers Project 22220 icebreakers, the first of which went critical in October 2019[5] and is expected to enter service in 2020.[4] and Project 23000E supercarrier.
