中国铅基研究反应堆概念设计研究

摘要

The conceptual design of 1 0 MWt China Lead-based Research Reactor (CLEAR-I) had been finished, which has critical and subcritical dual-mode operation capability for validation of ADS transmutation system and the Generation-IV lead-cooled fast reactor technology.Lead-bismuth eutectic was selected as primary coolant.The mature fuel and material technology was preferred,and the fuel assembly can be loaded by remote refueling system.CLEAR-I has excellent safety reliability,technology feasibility,experiment flexibility and technical continuity.The overview of reference scenario design, safety characteristics analysis and R&D status of the CLEAR-I was presented.%针对加速器驱动次临界系统预研装置和第四代铅冷快堆的技术发展目标和实验要求，完成了具有临界和加速器驱动次临界双模式运行能力的10 MW中国铅基研究堆CLEAR-Ⅰ概念设计.CLEAR-Ⅰ采用铅铋合金冷却，利用相对成熟的燃料和材料技术，通过全堆芯遥操自动更换燃料组件实现不同的实验目标，反应堆具有良好的现实可行性、安全可靠性、实验灵活性和技术延续性.本文简要介绍了CLEAR-Ⅰ概念设计参考方案，并总结了反应堆的安全特性和技术研发进展.
