Abstract

Abstract

The origin for welding deformations induced by unbefitting alignment,of spacer column assembly and thermocouple placed in improper position in Reactor Vessel Internals,is analyzed,and the design improvement of the front edge and the conduit nozzle is proposed,to effectively avoid the reoccurring of similar problems and provide the technical reference for the follow-up design of the spacer column assembly.
