design. As the RBMK, the EGP-6 uses water for cooling and graphite as a
neutron moderator. EGP is a Russian acronym but translated into English stand for Power Heterogenous Loop reactor. It is the world's smallest running commercial nuclear reactor, however smaller reactors are currently in development. The EGP-6 reactors are the only reactors to be built on
perma-frost.
There were only four EGP-6 reactors built which formed the
Bilibino Nuclear Power Plant, commissioned in 1974-1977, with a reactor becoming operational each year.
The reactors were responsible for supplying

can supply Bilibino's power grid despite being located approximately 200km away from the town.
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.
Sosny Spent Fuel Decommissioning
Spent fuel of the EGP-6 reactors were troublesome, as the remote location of the
Bilibino Nuclear Power Plant was difficult to get to with the small amount of transport infrastructure available
.The Sosny R&D Company gained access to the spent fuel produced by the reactors in 2010 and began reviewing optimal strategies for containing the nuclear waste product.
Spent fuel was often kept in reactor cooling pods or dry storage pools once they were depleted of useful energy, such as at the
Bilibino Nuclear Power Plant, the only location where EGP-6 reactors were commissioned.
The Sosny company performed diligent research on how to economically and safely move the spent fuel from the reactor site to a decommissioning location.
The optimal solution developed involved remote robotic arms which were used to delicately cut up the spent fuel and encapsulate the pieces into transport casks.
New transport infrastructure was designed specifically to remove the fuel from the reactor's remote location to Russia's mainland.
