摘　　要：针对核热推进反应堆核燃料的制备与考核问题,回顾了美国与苏联/俄罗斯在核热推进方面的研究,通过各种耐高温核燃料的热物性比较,给出了潜在可行的核燃料类型,并对未来最有潜力的钨基金属陶瓷燃料(CERMET燃料)与(U、Zr)C固溶体燃料进行了热物性参数、氢腐蚀考核等性能参数的研究对比分析。可为未来核热推进反应堆设计提供参考。Nuclear thermal propulsion(NTP)is one of the key technologies for the future deep space exploration missions.The production and research of the nuclear fuel are very important for the design of the NTP reactors.The researches of NTP in USA and Russia(USSR)were reviewed in this paper,and the potential NTP reactor fuel types were given after comparing the thermophysical parameters of various high temperature resistance nuclear fuels.Moreover,the CERMET fuel and(U、Zr)C solid solution fuel were compared on some key-physical parameters including the thermal physical parameters,the hydra corrosion,and the CTE parameters.This paper may provide useful references for the design of NTP reactors in the future.
