Combining with the 200MW low-temperature nuclear heating demonstration project in Daqing, the dynamic response analysis model of the interaction between fuel assemblies and fuel assemblies under seismic conditions is proposed according to the specific characteristics of the boxed assemblies. The linear and nonlinear The finite element analysis program ADINA performed a nonlinear dynamic response analysis of fuel assemblies and fuel assemblies on the outside under seismic conditions. The influence of the bearing conditions and the main parameters on the dynamic response was analyzed. The dynamic Response curves and curves of force and displacement of various parts of the model structure with time-history of earthquake acceleration are examined. The structural integrity of the box assembly under 200kW low temperature heating reactor under seismic conditions is verified and the cross- Pluggable
