, Jan. 3 -- Rosatom has completed the manufacture and commissioning of the first reactor core for 'Rossiya', the lead nuclear icebreaker of the next-generation "Leader" project (Project 10510). The fuel for the reactor was produced by the Machine Manufacturing Plant, part of Rosatom's Fuel Division, and located in Elektrostal.

The Rossiya will be powered by two RITM-400 reactors, which are 1.8 times more powerful than the RITM-200 reactors used on Project 22220 universal nuclear icebreakers such as Arktika. Together, two RITM-400 reactors will deliver a total shaft power of 120 megawatts, making Rossiya the most powerful icebreaker ever built.

Unlike universal icebreakers designed to operate in both deep and shallow waters, the "Leader"...
