Abstract

CRDM anti-seismic ring is one of the most important parts of pressurized water reactor vessel closure head upper assembly,and this paper gives the example of anti-seismic ring welding deformation,analyzes the principle and mechanism of the deformation,and puts forward the control measures,such as structure optimizing,welding process control,and machining craft optimizing;Proved by the practical application,these measures could effectively control the deformation of anti-seismic ring.
