On 11 July 2025, Rosatom started the preparatory work for the construction of BN-1200M reactor at the Beloyarsk Nuclear Power Plant. The reactor will be the 5th unit at the site.

The reactor at Beloyarsk NPP is the first of several fast neutron reactor units Rosatom is planning to build in the coming years. The long-term plan also envisions the development of reactors of a different, not yet specified type.
