Safety analysis of HTGR main steam pipe under steam hammer conditions
摘要
针对核电机组主蒸汽阀门突然关闭导致主蒸汽管道产生汽锤力
影响机组安全运行的问题
采用PIPENET软件模拟了高温气冷堆主蒸汽管道产生汽锤现象的过程
从内压、汽锤力及共振等方面分析了汽锤力对高温气冷堆主蒸汽管道安全性的影响。结果表明
汽锤现象发生时
管系应力不会超过许用应力
而且不会导致管系共振
高温气冷堆主蒸汽系统安全
对人员、环境和设备不会造成损坏。
Abstract
Sudden closure of the main steam valve in nuclear power plant will cause steam hammer occurring in the main steam pipeline
which will affect the unit safety operation.To solve this problem
the PIPENET software was employed to simulate the steam hammer process in high temperature gas-cooled reactor(HTGR).The effect of steam hammer force on the pipe safety was investigated
from the aspect of inner pressure
steam hammer force and resonance.The results show that
the main steam pipe of HTGR has adequate security margins when steam hammer occurs
so the steam hammer will not cause the pipes' resonance.Therefore
when the steam hammer occurs
the main steam system of the HTGR is safe
and it will not casue damages on human beings and the environment and the equipments.
