摘要
应用于大型先进压水堆CAP1400的灰控制棒吸收体材料,需要在中国实验快堆(CEFR)内进行辐照实验,获得辐照数据。该文对辐照方案进行设计介绍,从反应堆中子学、热工流体力学以及堆芯整体安全等方面进行研究论证,证明辐照组件入堆后对原有堆芯改变很小,不增加反应堆的原放射性物质释放总量,实验可行,也对后续同类辐照工作的开展提供了具体参考。
The gray control rod absorber material used in the large-scale advanced pressurized water reactor CAP1400 needs to be irradiated in the China Experimental Fast Reactor(CEFR)to obtain radiation data.This paper designs and introduces the irradiation scheme,and studies and demonstrates from the aspects of reactor neutronics,thermo-hydraulics and overall core safety,which proves that the original core is changed little after the irradiation module is put into the reactor,the total release of original radioactive material is not increased,and that the experiment is feasible,and also provides specific reference for the development of follow-up similar irradiation work.
