JAERI and JNC have begun the cooperative research of novel evaluation techniques of structural material degradation in FBR and LWR. The JNC has been developed the remote-controlled flux density measurement apparatus and set up in the MMF facility in JNC.

JNC has started two off-site (generic) underground research laboratory (URL) projects, one for sedimentary rock (Horonobe URL; Horonobe, Hokkaido) and the other for crystalline rock (Mizunami URL; Mizunami, Gifu). These URLs are those that the Long-term Program for Research, Development and Utilization of Atomic Energy (Long-term Program) by Atomic Energy Commission of Japan states their technical and social importance and expectation of earlier execution. History and current status of the Horonobe URL could give a good case to learn the technical and social aspects of URL projects of Japan.

This paper describes the summary of an interim report of phase II of the Feasibility Study on Commercialized FR Cycle Systems, related to reactor systems. Promising plant concepts (sodium-, lead-bismuth-, helium-, and water-cooled fast reactor) and reactor core concepts are presented. These concepts are quantitatively evaluated from the viewpoint of the suitability to the development targets, such as economic competitiveness, efficient utilization of resources and reduction of environmental burden, with securing safety. As results, sodium cooled fast reactor is well suited to the development targets. LBE cooled fast rector would have a potential to attain the development targets. Helium gas cooled fast reactor would have the great potential for high thermal efficiency and multipurpose energy system. And water cooled fast reactor has the advantage that there are many experiences with LWR. Furthermore the crucial issues for technical feasibility are also clarified as road map of key technology development for each concept.
