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M ONK9A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 ke f 。根据系统 ke f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 × 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 kef 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 .
