Development of fabrication technologies for advanced breeding functional materials for DEMO reactors

Hoshino, Tsuyoshi; Nakamichi, Masaru

DEMO reactors require advanced tritium breeder and neutron multiplier that have higher stability at high temperature. Li $_{2}$ TiO $_{3}$ with added Li (Li $_{2+x}$ TiO $_{3+y}$ ) have been developed such as advanced tritium breeder. Li $_{2+x}$ TiO $_{3+y}$ have higher stability at high temperatures with reduction atmosphere. We have been promoting the development of fabrication technique of Li $_{2+x}$ TiO $_{3+y}$ pebbles by the emulsion method, one of the sol-gel methods. The average diameter and the sphericity of pebbles by the emulsion method were 0.95 mm and 1.02, respectively. On the other hand, beryllium intermetallic compounds (beryllides) are promising material for advanced neutron multipliers. In this study, trial fabrication examinations were carried out. The formation of Be $_{12}$ Ti intermetallic was identified using a mixture of Be and Ti particles for the plasma sintering method.
