BN-1200 reactor power unit design development

In February 2010, the RF Government has approved the Federal Target Program "New Generation Nuclear Power Technologies for the Period of 2010-2015 and for the long-term up to 2020". Within this Program, the R&D work for new generation 1200MWe sodium fast reactor is provided. The BN-1200 design is based on the combination of approved and innovative technical decisions, which allow: – reliable power unit with large BN reactor to be developed in a short period of time for commercial construction as a part of closed nuclear fuel cycle; – qualitatively new technical level of power unit to be provided according to generation 4 NPP requirements. The paper characterizes the activities performed now for the power unit design in various areas: – power unit design; – reactor plant (RP) detailed design development; – R&D work to validate the RP system and equipment; – code upgrading and verification; – safety validation.
