Abstract

Abstract

Nonlinear seismic model for reactor with fuel assemblies of AFA 2G and AFA 3G is established.Using ANSYS software,seismic nonlinear time-history analysis is completed and the effects on seismic loads of reactor system are obtained.The result shows that when the fuel assembly changing from AFA2G to AFA 3G,it is necessary to reevaluate the fuel assembly itself,but not the reactor internal.
