| Abstract: | Containment sump is an important and safety injection system of PWR NPP. Strainer part of safety features of containment spray system clogging of containment sump will impact the normal operation of containment spray system and safety injection system, and challenge the safety of NPP. Many countries with NPP have researched the issues of sump strainer clogging. The regular bodies have also issued bulletins that status and development o requ f the ired the licensee of NPP resolved the problem. This paper introduces the issues of containment sump strainer clogging. |
