The basic conceptof DEMO premised for investigation has been identified and the structure of technological issues to ensurethe feasibility of this DEMO concept has been examined. The Joint-Core Team, which was launched alongwith the request by the ministerial council, has compiled analyses in two reports to clarify technologywhich should be secured, maintained, and developed in Japan, to share the common targets amongindustry, government, and academia, and to activate actions under a framework for implementationthroughout Japan. The reports have pointed out that DEMO should be aimed at steady power generationbeyond several hundred thousand kilowatts, availability which must be extended to commercialization,and overall tritium breeding to fulfill self-sufficiency of fuels. The necessary technological activities, suchas superconducting coils, blanket, divertor, and others, have been sorted out and arranged in the chartwith the time line toward the decision on DEMO. Based upon these Joint-Core Team reports, relatedactions are emerging to deliberate the Japanese fusion roadmap.}, pages = {1318--1325}, title = {Japanese endeavors to establish technological bases for DEMO}, volume = {109/111}, year = {2015} }
