摘要
千瓦级空间核反应堆电源具有能量密度大、工作寿期长、环境限制少等优点,是低功率深空探测器用电源的理想之选。美国和苏联都曾对千瓦级空间堆电源进行过大量研究,先后提出ROMASHKA、BUK、TOPAZ-1、TOPAZ-2、SNAP-10A和Kilopower等6种典型设计方案。各方案因设计差别而具有不同特点,其中,Kilopower具有质量轻、能量转换效率高、可靠性高、工作寿期长、自主运行等诸多优点,是目前最优秀的设计方案。通过对各方案的对比,可以得出结论,热管冷却式快堆将成为千瓦级空间堆未来的主要发展方向。
Kilowatt space nuclear reactor power system is a ideal power supply for deep space detector, for its advantages such as high energy density, long working life, little environmental restriction and so on. The United States and the Soviet Union did a lot of research on kilowatt space nuclear power systems, putting forward six typical designs named ROMASHKA, BUK, TOPAZ-1, TOPAZ-2, SNAP-10 A and Kilopower. Each scheme has different characteristics, and Kiopower is the best one of them, with advantages such as light weight, high energy conversion efficiency, high reliability, long working life, independent operation and etc. Based on the comparison of these schemes, it is concluded that the heat pipe cooled fast reactor will be the main development direction of the kilowatt space reactor in the future.
