Development of Solid Breeder Blanket at JAERI

Abstract

Japan Atomic Energy Research Institute (JAERI) has been performing blanket development based on the long-term research program of fusion blankets in Japan, which was approved by the Fusion Council of Japan in 1999. The blanket development consists of out-pile R&D, In-pile R&D, TBM Neutronics and TPR Tests and Tritium Recovery System R&D. Based on the achievements of element technology development, the R&D program is now stepping to the engineering testing phase, in which scalable mockup tests will be performed for obtaining engineering data unique to the specific structure of the components, with the objective to define the fabrication specification of test blanket modules for ITER. This paper presents the major achievements of the element technology development of solid breeder blanket in JAERI.
