Abstract

According to the RCC-M rule,1/4 scale model of the nozzle of pressurizer surge lines in Qinshan Phase II project is established,and the elastoplastic analysis is conducted.10 cycles of loads is calculated firstly,and then the response of pipe after which endured 100 cycles is calculated by extrapolation.The assessment results show that the plastic instability of pressurizer surge line will not occur under the most severe cyclic load of load case II.
