深海調査用高速炉について用途別に検討を行っている。ここではこれらの動力源のうち,近い将来に需要があると期待される無人基地用動力源(水深8020mを想定,10kWe)および1万m級潜水調査船用動力源(20kWe)について概念を構築した。出力変換方式として前者では熱電気セルおよび密閉ブレイトンサイクルを,後者では密閉ブレイトンサイクルを採用している。このような深海調査用動力源では重量が軽いほど好ましい。構築した概念に基づく計算の結果,この高速炉システム総重量は耐圧殻容器込みで,1万m潜水調査船用動力源でも10トン以下になる見通しを得た。

Fast reactor power systems for deep sea research were studied to some types of usage. Two concepts were figured out to power sources for an uninhibited base (water level 8,020 m, 10kWe) and for a 10 km class research submersible (20 kWe), which are expected to be required in near future. Whereas the power conversion system of the uninhibited base adopted thermoelectric cells and a closed Brayton cycle, that of the submersible used a closed Brayton cycle. It is favorable that the power system for deep sea research is as light as possible. The calculated weight of these power sources showed that the total value including a a pressure shell container will be less than an objected value of 10 tons even in the 10 km class research submersible.
