RITM-200
Integral 175 MWt marine PWR; two units per Project 22220 Arktika-class nuclear icebreaker.
The RITM-200 is a pressurised water reactor of integral design. It is rated at 175 MWt and uses uranium enriched up to 20%, with a core life of about 7 years. Each unit weighs 147.5 t and measures 7.3 m high by 3.3 m in diameter. It is about half the weight of the KLT-40, more compact, and 25 MW more powerful. Two units power each Project 22220 icebreaker (Arktika, Sibir, Ural and later ships).
