Conference Article: Design features of BREST reactors and experimental work to advance the concept of BREST reactors

Abstract

Principle design features of BREST-300 (300 MWe) and BREST-1200 (1200 MWe) lead-cooled fast reactors are presented in this paper. Several experimental works have been performed or under way in order to justify lead-cooled reactor design concepts. BREST reactor designs of different outputs have been developed using the same principles. In conjunction with the increased output and the implement of inherent safety concept, a number of new solutions, which may be applied to the BREST-300 reactor design too, have been considered in the BREST-1200 reactor design. The new design features adopted in the BREST-1200 reactor design include: pool?type reactor design not requiring metal vessel, hence, not limiting reactor power; new handling system allowing to reduce central hall and building dimensions as a whole; emergency cooling system using field pipes, immersed directly in lead, which may be used to cool down reactor under normal conditions; by?pass line incorporated in coolant loop allowing to refuse the actively actuating valve initiated in pumps shut down.
