Title
(ZH) 内置式蒸汽稳压器
Abstract
(ZH)

本实用新型公开一种内置式蒸汽稳压器,与压力容器的上封头一体化布置,其包括隔板、电加热管及喷淋设备,隔板设置于上封头的底部以将压力容器的内部分隔成冷却剂空间及稳压器空间,隔板上开设有多个连通冷却剂空间、稳压器空间的波动孔,电加热管设于隔板的上方并位于稳压器空间内,喷淋设备设于上封头的顶部并连通一回路冷却剂系统。将稳压器与上封头一体化布置,结构简单紧凑,制造方便,降低成本;而通过波动孔来代替波动管结构,消除了波动管发生破口的可能性,强化了反应堆与稳压器之间的流量波动;同时,稳压器将上封头与反应堆冷却剂隔开,降低了上封头法兰的热应力,该内置式蒸汽稳压器具有更高的经济性及更高的安全性。
