The EGP-6 is a Russian small nuclear reactor design. It is a scaled down version of the RBMK design. As the RBMK, the EGP-6 uses water for cooling and graphite as a neutron moderator. It is the world's smallest commercial nuclear reactor.[1]

There were only four EGP-6 reactors built which formed the Bilibino Nuclear Power Plant, commissioned in 1974-1977. The plant design was developed by the Ural Division of Teploelektroproekt together with Izhorskiye Zavody and FEI in Obninsk.[2] Each EGP-6 reactor at Bilibino produces 62 MW thermal power, generating 12 MW electrical power (11 MW net capacity). As of 2020, the power plant is ready for decommissioning and awaits to be replaced by the Akademik Lomonosov floating nuclear power plant, which started regular operation in May 2020.[3] The first EGP-6 reactor was shut down in December 2018, and the other 3 EGP-6 reactors were scheduled to follow December 2021, however a decision was made in 2020 to renew the license of one of the three reactors until December 2025.[4][5]
