摘　　要：为提高核动力航天器关键技术的可继承性与可扩展性,缩短核动力航天器研发周期,降低研发成本,本文通过总结国外核动力航天器发展现状,梳理核动力航天器研制特点,结合模块化航天器概念及设计原则,首次提出模块化核动力航天器概念。将核动力航天器分为核电源模块、平台中心模块、载荷模块3大独立模块,并针对体系架构设计提出3层建设方案,针对模块化核动力航天器梳理关键技术难点,为后续项目研究提供应用参考。In order to improve the inheritance and extendibility of the key technologies of nuclear powered spacecrafts and reduce the cycle and cost for the research and development,combined with the concept and design principle of modular spacecrafts,the concept of modular nuclear powered spacecrafts is proposed for the first time based on the summarized development status and characteristics of nuclear powered spacecrafts abroad.In the concept,a nuclear powered spacecraft is divided into three independent modules,i.e.,nuclear power module,platform module,and load module,and a three-level development scheme is proposed for the architecture design.Finally,the key technical difficulties of modular nuclear powered spacecrafts are analyzed and concluded,which could provide reference for the further research.
