为了有效地利用裂变反应堆的热量，人们认为可以通过碘-硫还原反应将水高效地转化为氢。为了有效地做到这一点，有必要根据三个不同的温度进行I-S循环中包括的三种反应，并且从高温反应堆的一次和二次冷却剂循环提供处于它们各自温度的热量。在本研究中，它是分析澄清，I-S循环温度的定义和三个不同温度的热量提供的冷却剂回路。采用吸氢合金填充的热泵系统有效地提高了反应堆的热量。实验研究了Zr（V1-XFeX）2合金在各自温度下的吸氢行为。通过实验验证了其吸氢性能和热强化效果。通过实验和理论分析，证明了热泵循环提高了系统的整体效率。

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.
