摘　　要：分析了低温供热堆热电联供所提供的热源和冷源的特点，根据５ＭＷ、２００ＭＷ、５００ＭＷ低温供热堆的设计工况，针对氨水朗肯循环、水蒸汽朗肯循环、水蒸汽扩容循环、卡林那循环和氦气循环等动力循环方式，进行了详细计算、分析、比较。结果表明，氨水朗肯循环具有相对较高的发电效率，是一种很有潜力的低温动力循环；水蒸汽朗肯循环对于堆芯进、出口温度差较小的堆型具有明显的优势；而水蒸汽扩容循环却是堆芯进、出口温度差较大堆型的首选循环。This paper analyzes the characteristic of heating source and cooling source offered by nuclear heating reactor cooperation.Based on design parameters of 5MW, 200MW, 500MW nuclear heating reactor,some power cycles,ammonia-water Rankine cycle, steam Ranking cycle;hot water flash cycle; Kalina cycle and helium gas cycle, have been calculated,analyzed and compared. The result shows that ammonia-water Rankine cycle has higher electricity efficiency, with the problem of comrrosiveness and stability overcome to be a widely applicable power cycle; steam Rankine cycle is ripe power cycle for nuclear heating reactor with smaller temperature dif- ference between reactor core input and output; but for larger temperature difference situation, hot water flash cycle has higher electricity efficiency to be a first recommended power cycle.
