核电厂堆芯补水箱抗震鉴定分析
Seismic Qualification of Core Makeup Tanks Used in Nuclear Power Plants
摘要
Abstract
The acceleration of construction of nuclear power plants in China has made the qualification problem of corresponding nuclear equipment become salient.For some specific nuclear equipments,it is only possible to adopt analytical methods for seismic qualification of nuclear equipment due to the condi -tion limitations of existing test bench or the requirements of its own characteristics.With respect to this problem,this paper gives the service conditions,methods and steps for seismic qualification of nuclear equipment by analytical method;adopts analytical method to carry out seismic qualification and analysis of the core makeup tank:build the finite element analysis model;give the load combinations and stress limits related to seismic analysis;apply the finite element software ANSYS to carry out static analysis,prestress modal analysis and response spectrum analysis of the core makeup tank;and assess the safety performance of core makeup tank under seismic condition according to the stress limits,which provides references for seismic qualification of nuclear equipment by analytical method.关键词
