Shell Safety Analysis of Spray Pumps in Nuclear Power Plants Under Thermal Shock and Seismic Motion
This paper introduces the composition and operating principle of the spray system in a nuclear power plant. Based on the performance requirements of the spray pump in a certain nuclear power plant,Ansys software is used to es-tablish a shell calculation model and analyze the safety of the shell under thermal shock and seismic motion.The results show that under the impact of thermal stress,seismic stress,and their combination,the maximum stress on the shell structure is lower than the allowable stress under seismic motion.The structural design of the spray pump shell is rational and can meet the accidental condition criterion.
