Calculation and Analysis of Neutron Time-spatial Kinetics in Uncontrolled Withdrawal Accident of Regulating rod in CEFR

  • 1. China Institute of Atomic Energy (China)

Description

Feedback calculation model: – NKF: → reactivity is obtained by the calculation formula of the reactivity; → fuel temperature,coolant temperature and some other parameters are averages over the whole core; → not considering the differences in the various components; → temperature feedback coefficients are given in advance, not change with temperature. – NAS-K: → feedback effects are directly reflected in the cross section; → considering the changes of spatial distribution; → considering the relationship between the rate of various reactivities and the current temperature; → feedback model of the NAS-K is more accurate
