Rosatom has manufactured the world's most powerful RITM-400 ship reactor plant for the Russia nuclear icebreaker of Project 10510. The newest reactor plant has been named Ilya Muromets, it has a thermal power of 315 MW and is the most powerful ship reactor plant in the world.
The design and layout of the RITM-400 is based on maximum unification with the RITM-200 reactor, which has proven itself well on the nuclear icebreakers of Project 22220. The RITM-200 is also designed according to a two-circuit scheme, with four steam generators integrated into the core.
The main difference between the RITM-400 reactor plant is a twofold increase in reactor power, which allows the Project 10510 nuclear-powered ship to break through ice up to 4 meters thick for piloting large-capacity vessels. The planned power on the shafts with two reactor plants is 120 MW.
