DEMO Activities in the Broader Approach and Beyond

In the Broader Approach (BA) activities, cooperated work on the DEMO design is undertaken with the IFERC project team and home teams in the EU and Japan. System code benchmarking to establish the common design tools and the definition of critical design issues have been progressed so far. The BA DEMO design work is focusing on the common critical issues such as divertor design, remote maintenance scheme, and blanket design. In parallel, safety research for the fusion power plant started re-analyses, which include severe events such as total loss of coolant without any electric power. In the DEMO R&D activities, five R&D tasks related to blanket materials and technology are carried out intensively according to the common interests of the EU and Japan for DEMO. A neutron source using the IFMIF/EVEDA prototype accelerator and the IFMIF/EVEDA lithium target test loop is under discussion as one of the major activities after 2017.
