100kWe月面核电站方案研究

Scheme Research on 100kWe Lunar Surface Nuclear Power Plant

随着太空探索活动的深入开展,在月球表面建立有人基地成为必然选择。与常规化学能或太阳能相比,月面核电源具有诸多优点,是月球基地的最佳能源选择之一。本文提出了电功率100 kWe的核反应堆电源系统方案,给出了该方案的关键系统参数。针对反应堆模块,展开方案选型、参数优化、常规物理参数分析、初步热工分析和特种临界安全分析等工作。计算结果显示:燃料包壳温度小于使用限值,掉落事故工况下有效增值因数均小于0.98。该设计方案满足各项技术指标和设计准则。

With the development of space exploration activities,the establishment of manned bases on moon surface has become an inevitable choice. Compared with conventional chemical or solar energy,lunar surface reactor power source has many advantages,which makes it one of the best energy options for a lunar base. In this paper,a scheme of 100 kWe nuclear reactor power system is proposed,and the key system parameters of the scheme are given.In terms of the reactor modules,much work has been carried out,e. g.,scheme selection,parameter optimization,analyses of the conventional physical parameters,preliminary thermal-hydraulic analysis,and special critical safety analysis. The calculation results show that the temperature of the fuel cladding is less than the use limit,and the effective increment factorsunder drop accident conditions are less than 0.98,which indicates that the scheme meets the technical specifications and design requirements.
