The RITM-200 is an integrated
generation 3+ pressurized water reactor
A pressurized water reactor (PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary coolant (water) is ...

OKBM Afrikantov and designed to produce 55 MWe. The design is an improvement of
KLT-40 The KLT-40 family are nuclear fission reactors originating from OK-150 and OK-900 ship reactors. KLT-40 were developed to power the ''Taymyr''-class icebreakers (KLT-40M, 171 MW) and the LASH carrier '' Sevmorput'' (KLT-40, 135 MW).[uranium-235
Uranium-235 (235U or U-235) is an Isotopes of uranium, isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile ...]
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 the
Project 22220 icebreakers, the first of which went critical in October 2019.
In November 2020 Rosatom announced plans to place a land-based RITM-200N

. The reactor will replace current coal and oil based electricity and heat generation at half the price.
Technical design for this type of RITM-200 core should be finished in 2022.
