In order to utilize fission reactor heat effectively, it is considered that water is converted with high efficiency to hydrogen by using the iodine-sulfur reduction reaction. In order to do thateffectively, it is necessary that three kinds of reactions included in the I-S cycle proceed in accordance with three different temperatures and heat at their respective temperatures is supplied from the primary and secondary coolant cycle of high-temperature reactor. In the present study, it is analytically clarified that the I-S cycle temperature is defined and heat of three different temperatures is supplied from the coolant loop. Heat pump packed with hydrogen-absorbing alloys is utilized to enhance reactor heat efficiently. In experiment, hydrogen absorbing behavior of Zr(V1-XFeX)2alloys is experimentally investigated at their respective temperatures. The hydrogen absorbing performance and heat enhancement are proved experimentally. It is proved experimentally and analytically that the overall efficient is improved by the heat pump cycle.

为了有效地利用裂变反应堆的热量，人们认为利用碘-硫还原反应可以高效地将水转化为氢。为了有效地做到这一点，I-S循环中的三种反应必须按照三种不同的温度进行，并且在各自温度下的热由高温反应堆的一次循环和二次循环提供。在本研究中，解析地阐明了I-S循环温度的定义，以及从冷却剂回路提供三种不同温度的热。利用吸氢合金填充的热泵有效地提高了反应堆的热量。在实验中，对不同温度下的吸氢行为进行了实验研究。通过实验验证了该材料的吸氢性能和热强化效果。实验和分析表明，热泵循环提高了系统的整体效率。
