Description

To realize fast breeder reactor until 2050, high Cr heat-resistant steel has been developed for materials of the cooling system and fuel cladding. Mod. 9Cr-1Mo steel, precipitation hardening ferritic steel, was used to the cooling system. Chemical compositions, history, the present statue of research activities about Mod. 9Cr-1Mo steel and application to fast breeder reactor are described. 9Cr-ODS (Oxide dispersion strengthened ferritic steel) for the fuel cladding is reported with background, history, the present statue of researches, fine structure, production process, and development plan. Illustrated are the outline of realization of fast breeder reactor in Japan, compactification of fast breeder reactor plant by application of high Cr heat-resistant steel, heat-resistant and irradiation-resistant property of ODS, fine structures of 9Cr-ODS, production process of ODS, improvement of cooling work and strength by controlling the cooling rate, the short-time strength and internal pressure creep rupture strength of 9Cr-ODS, PNC-316 and PNC-FMS, and development plan of ODS.
