备注

深空探测技术的发展对动力系统提出了更高的要求。传统的太阳能电源与化学电源的适用范围较小,环境适应能力不强,而微型核反应堆电源能量密度高,不依赖太阳光照,可应用于轨道运输、高轨探测多场景任务。在微型核反应堆电源技术路线中,热管冷却核反应堆电源因其系统设备极大简化、模块化设计,高可靠的全固态堆芯、非能动传热及瞬态响应迅速等特性,成为空间核反应堆电源最具可行性的路线之一。通过文献调研总结目前空间热管堆发展现状,从发展历史出发,梳理热管冷却核反应堆电源设计和理论研究,总结热管冷却核反应堆电源发展方向和关键技术。
The development of deep space exploration technology has been restricted by reliable engine power. The traditional solar power source and chemical power source have a small scope of application, and the environmental adaptability is not strong, while the micro nuclear reactor power source has high energy density. It does not depend on sunlight and has strong survivability, which can be applied to multi-scene tasks. In the design scheme of the power supply of the miniature nuclear reactor, the heat pipe reactor has become one of the most promising options for the power supply of space nuclear reactors due to its modular design idea, simplified reactor structure, good inherent safety characteristics and transient response characteristics. This paper summarizes the current development status of space heat pipe reactors through literature research. Starting from the development history, it sorts out the design and theoretical research of heat pipe reactors, summarizes the development directions and key technologies of heat pipe reactors.
