As for the nuclear power safety, a variety of non-destructive testing on the production of nuclearfuelassembly is required during the manufacturing operation in NPIC.
FITLINK is one of main programs of NDFMPS that is core nuclear design and fuel management program system, and is a treatment program of cross section parameter of fuel assembly.
The reload strategy is from 12 months to 18 month of GNPS, the fuelassembly changed from AFA 2g to AFA 3g and core nuclear data been changed, thus many accidents need to be reanalyzed.
大亚湾核电站由年换料改为18个月换料，燃料组件由AF A 2g改为afa 3g，堆芯中子学参数发生了较大变化。因此，需要对许多事故重新进行分析。
