21世紀のエネルギ源として期待されている水素製造を主なる目的とした高温高速炉のイメージを構築するために概念を検討を行った。検討は、水素製造装置との取合を考慮した、下記の範囲である。1)原子炉構造2)冷却系3)安全系及び格納容器結果から、コンパクトな原子炉構造、熱交換器等の概念を得ることができた。また、別途、検討した高温高速炉により水素製造の大まかなコスト評価も行い、すでに発表されている高温ガス炉のそれと比較しても十分な経済競争力を持っている可能性のあることを示した。

A conceptual design study has been performed in order to establish an outline image of the High Temperature Fast Reactor (HTFR) which has been aimed to produce the hydrogen as a most promising energy source in 21st century. The study covers the following systems. (1)Reactor system (2)Cooling system (3)Safety system and containment From results of the study, the concepts of the compactized reactor system and the heat exchanging system has been presented. Based on the concept obtained, a preliminary estimate of the cost of hydrogen produced by the HTFR was also conducted in another report. Result revealed that the cost is compatible with that by the High Temperature Gas-cooled Reactor (HTG CR) already published.
