Design Improvement for Spacer Column Assembly

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 通过分析反应堆堆内构件上支承柱在制造过程中由于对中不好导致焊接变形以及上支承柱组件内热电偶安装不到位的原因,提出对上支承柱组件增加止口设计和端塞等设计改进,有效地避免了同类问题的再次发生,为后续核电厂堆内构件上支承柱组件的设计提供技术参考。

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.
