実際のシェル構造では何らかの形状不整が存在する。構造の信頼性を確保するためには形状高温高速炉を熱源として利用し得る水素製造法である,熱化学法の1つであるUT-3法と,水を効率良く電気分解する固体電解質高温水蒸気電解法について,検討を行った。前者については水素製造プラントシステムの概念検討を行い,水素製造コストの試算を行った。後者については,研究現状を調査した。前者は高温高速炉の熱の有効利用の点から魅力的な水素製造法であるが,材料問題等実用化迄に解決すべき大きな課題が存在する。後者は改良水電解法の1であり,高温高速炉の熱の有効利用の点からは前者程の魅力に欠けるが,技術的な課題は前者より少ないと考えられる。

Study was performed on UT-3 thermochemical method and a high temperature steam electrolysis method using a solid electrolyte which were hydrogen production methods to use effectively thermal energy from a high temperature fast reactor(HTFR). For the former, the concept of hydrogen production plant system was studied for the first time and hydrogen production cost was calculated by using the concept. Present status of research was studied for the latter. The former is a very attractive hydrogen production method from the point of effective use of the thermal energy produced by the HTFR but it has big problems to be solved before commercialization. The latter, which is one of improved electrolysis methods, does not have attractiveness as large as the former in the point of thermal energy utilization, but it seems not to have unsolved problems as difficult as the former.
