Fatigue Analysis on the Internals of Qinshan 600 Mwe Nuclear Reactor in Flow-Induced Vibration Test Using the Extreme Value Distribution Method

摘要

A method analyzing the fatigue life of reactor's internals with extreme value distribution technique is presented in this paper. On the basis of giving the means to calculate the extreme loads, the testing load of Qinshan 600MW Reactor's internals was analyzed. It comes to the conclusion that the effect of the flow-induced vibration on the fatigue life of the reactor's internals during the design service life can be ignored and the valuable data for determination of the minimum record duration of reactor internals' flow-induced vibration test were given.
