摘要
探究RAFM钢作为偏滤器靶板热沉的替换材料,验证其在3种不同工况下的结构强度并预测其在交变载荷下的疲劳寿命。得出3S_m法则下W/RAFM钢偏滤器靶板最大可承受热负荷为8MW·m^(-2)。结合中国聚变工程实验堆(CFETR)的设计目标,如果以ITER偏滤器两年运行周期为设计准则,最大承受热负荷为7MW·m^(-2)。考虑到偏滤器靶板区域呈现高热负荷低中子辐照、挡板和DOME板区域低热负荷高中子辐照特性,可以采用W/Cu和W/RAFM双路偏滤器靶板的结构设计。
The possibility of W/RAFMs divertor target using the RAFMs as the heat sink,and prediction of fatigue life under different operation condition were investigated.The maximum tolerable heat load is 8MW·m^-2. The magnitude will be reduced to 7MW·m^-2if considering the 2years operational cycle time.Taking into account the profile of heat load and neutron irradiation,the structural design of W/Cu and W/RAFM dual divertor target plates can be used.
