重金属冷却炉における有望概念として、炉心性能向上の観点から有望と評価された自然環循及び強制循環冷却方式の中小型Pb-Bi冷却炉について概念設計研究を実施した。その結果、両概念とも経済性、炉心性能目標を達成可能な見通しである。

Focusing on the cover layer materials (as the Radon Barrier Materials), which could have the effect to restrain the radon from scattering into the air and the effect of the radiation shielding, we produced the radon barrier materials with crude bentonite on an experimental basis, using the rotary type comprehensive unit for grinding and mixing, through which we carried out the evaluation of the characteristics thereof.
