In the feasibility studies of commercialization of an FBR fuel cycle system,the targets are economical competitiveness to future LWRs, efficient utilization of resources, reduction of environmental burden and enhancement of nuclear non-proliferation, besides ensuring safety. Both medium size pool-type lead-bismuth cooled reactor with primary pumps system and without primary pumps system are studied to pursue their improvement in heavy metal coolant considering design requirements from plant structures. The design of plant systems are reformed, and the conceptual design is made and the commodities are analyzed. (1)Conceptual design of lead-bismuth cooled reactor with pumping system Electrical output 750 MWe and 4-module system The heat-mass balance is optimized and drawings are made about plant layout, cooling system, reactor structure and cooling component structures. (2)Structural analysis of main components (3)Conceptual design of natural circulation type lead bismuth cooled reactor Electrical output 550 MWe and 6-module system The heat-mass balance is optimized and drawings are made about plant layout, cooling system, reactor structure and cooling component structures. (4)Study of R&D program
