| Abstract: | 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 keff of different enrichment fuels at different burnups. A reference loading curve was proposed in accordance with the system keff’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. |
