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. 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.
It powers Project 22220 icebreakers, the first of which went critical in October 2019 and is expected to enter service in 2020. and Project 23000E supercarrier.
