针对秦山二期乏燃料水池开展采用燃耗信任制技术的密集贮存临界安全分析研究,燃耗计算使用二维组件燃耗计算程序CASMO5,临界计算使用MCNP5程序。分析对象为由6×6排列的贮存槽构成的贮存格架,考虑燃耗信任制的密集贮存池是在原贮存池基础上进行的改进,贮存格架大小数量结构都不变,贮存格架内贮存槽由6×6升级为7×7,如图1所示。
According to the critical safety analysis of intensive storage using the fuel consumption trust system for Qinshan Phase II spent fuel pool, the burnup calculation uses CASMO5, a two-dimensional component burnup calculation program, and the MCNP5 program for critical calculation. The analysis object is a storage rack composed of 6 × 6 storage tanks. The intensive storage tank considering the fuel consumption trust system is an improvement on the basis of the original storage tank. The quantity and structure of the storage rack are the same in number and size, Storage tank upgrade from 6 × 6 to 7 × 7, as shown in Figure 1.
