Abstract

Abstract:

Since the commercial operation of nuclear units of CGN Yangjiang Nuclear Power Company Limited, there have been 15 cases of excessive oxygen content in the storage tank REA001/002BA for demineralized and deoxygenized water. The water tank is mainly used for water makeup to the primary loop. If the oxygen content exceeds the standard, the makeup water of the primary loop of the nuclear power plant will be unqualified, which will seriously affect the safe operation of the unit. Considering the REA001/002BA water loop equipment, equipment in REA tank room, piping and valves of pump room, and REA sampling equipment, the excessive oxygen content is analyzed and the treatment measures are proposed.

Key words:
