RITM-200N
Under construction Rosatom
Output
55MWe
RITM-200N is a light water-cooled reactor design from Rosatom rated at 55 MWe. Nuclear construction has begun.
The land-based version of the icebreaker reactor Rosatom has been building and operating at sea for years. That operating heritage is a real advantage over Western designs that exist only on paper, and commissioning is expected in 2028.
