The Fusion Council of Japan has established the long-term research and development program of the blanket in 1999. In the program, the solid breeder blanket was selected as the primary candidate blanket of the fusion power demonstration plant in Japan. In the program, Japan Atomic Energy Research Institute (JAERI) has been nominated as a leading institute of the development of solid breeder blankets, in collaboration with universities, for the near term power demonstration plant, while, universities including National Institute for Fusion Science (NIFS) are assigned mainly to develop advanced blankets for longer term power plant development. In the long term research and development program, ITER blanket module testing is identified as the most important milestone, by which integrity of candidate blanket concepts and structures are evaluated. In Japan, universities, NIFS and JAERI cover a variety of types of blanket development. This paper presents a plan and strategy for ITER blanket module testing in Japan.

Safety analysis of ITER test blanket module for water cooled blanket with pebble bed breeder

Test module testing in ITER is one of the most important mile-stone for development of the DEMO blanket. In the design of test modules in ITER, it is very important to show that test modules do not cause additional safety concern to ITER. This work has been performed for the evaluation of the substantial safety of Test Module of Water Cooled Solid Blanket, which is the current candidate blanket for the DEMO blanket in Japan. Major issues of the evaluation were establishment of post accident cooling in TM, hydrogen gas generation by Be-steam reaction, and pressure increase and spilled water amount by Loss of Coolant Accident (LOCA) event. The evaluation was performed to derive the upper bound of consequences in significant events, of which scenario can be assumed by the similarity of the safety analysis of Shielding Blanket.

A fusion relevant neutron source is strongly desired for blanket functional tests and material tests toward DEMO. The International Fusion Material Test Facility (IFMIF) is one of the most promising candidates of the fusion relevant neutron source. Here, a plan is presented for a new neuron source using an IFMIF/EVEDA prototype accelerator with 125 mA and 9 MeV D$$^{+}$$ beam and a lithium test loop for the IFMIF target facility. Expected performances of three options (9 MeV and upgrading to 26 or 40 MeV) are discussed. The option of 40 MeV is desirable, however, the option of 26 MeV is acceptable for blanket functional tests and material tests.
