Advanced sodium fast reactor unit concept

The paper presents status of development for 1200 MW power unit with sodium fast reactor for commercial construction in the Russian Federation. General characteristics of the reactor plant (RP) and power unit as well as goals that shall be achieved because of design development are described. The power unit design is based on technical decisions, which have been partially proven during sodium reactor operation in Russia and partially have been validated by R and D work for BN-800 RP. At the same time, new technical decisions are applied that improve safety and technical-and-economic indices. To validate them, the corresponding R and D work shall be performed. It is planned to construct the pilot power unit in 2020 and to put into operation the next commercial power units of this type using plutonium generated in the thermal reactors. (author)
