Sealing Behavior Analysis Method of Reactor Pressure Vessel under Asymmetric Preload
摘要
Abstract
For the reactor pressure vessel (RPV) threaded hole damage analysis of sealing performance,a finite element model containing three bolts and surrounding structure was built,compared with which was a 180 degree model.Based on the models,the sealing performance under the asymmetric preload was studied.The key indicators are deduced,include vertical displacement,horizontal displacement,bolt loads,etc.It shows that both models can verify the performance of the seal structure,which used to evaluate the reliability of the RPV sealing structure,and is the basis to solve the sealing problem of main bolt damage cases.关键词
