2226 実用化戦略調査研究におけるナトリウム炉概念検討(小型炉)

抄録

In the "Feasibility Study on Commercialized Fast Reactor Cycle Systems", attractive concepts of sodium-cooled small-scale reactor have been studied from standpoints of utilizing inherent and passive safety, attaining long lived core, simplifying operation and maintenance. The tank and forced sodium circulation-type concepts were proposed (electricity output of 150MWe), which had circular IHX and EMP inside reactor, with parameter of reactivity control method (reflector or control rod). And it was clarified that this concept had potential to produce hydrogen by changing system specification.
