摘　　要：以田湾核电站(TNPS)2×5排列的贮存格架构成的乏燃料水池为例,研究采用燃耗信任制技术的密集贮存和临界安全问题。采用MONK9A程序计算分析不同富集度、不同燃耗的乏燃料装载情况下系统的keff。根据系统keff随不同初始富集度燃料的燃耗变化情况给出了水池的参考装载曲线。采用燃耗信任制技术的密集贮存方案能提高贮存能力31%。Exampled by the spent fuel pool of TNPS which is consist of 2 X 5 fuel storage racks, the spent fuel high-density storage based on burnup credit （BUC） and related criticality safety issues were studied. The MONK9A code was used to analyze koff of dif- ferent enrichment fuels at different burnups. A reference loading curve was proposed in accordance with the system kef s changing with the burnup of different initially enriched nuclear fuels. The capacity of the spent fuel pool increases by 31% compared with the one that does not consider BUC.
