RIA Novosti cited Rosenergoatom CEO Yevgeny Romanov as saying to the Beloyarsk NPP’s press office that fifth power unit of Beloyarsk will be the first to get a next-generation reactor installed on-site to enable a closed nuclear fuel cycle.

The 1,200MW fast-breeder BN-1200 reactors feature a liquid metal heat-transfer agent as a coolant.

In addition to significantly reducing radioactive waste, the reactors will expand the range of fuel used at NPPs.

Russia’s nuclear plant operator launched the controlled nuclear fission at the BN-800 breeder reactor, which is considered a prototype of the BH-1200, in June 2014.

The controlled nuclear fission is likely to reach the target energy output of 880MW in October.
