GB/T 44389-2024
ActiveIce plug isolation of piping in nuclear power plant
核电厂管道冰塞冷冻隔离
Application Summary AI generated
This standard specifies the technical requirements, operational procedures, and safety verification methods for creating ice plugs to isolate sections of piping in nuclear power plants. It is applied during maintenance, repair, or modification work on reactor coolant systems and auxiliary pipelines, where temporary isolation is needed without draining the entire system. The standard ensures the ice plug maintains structural integrity and leak-tightness under nuclear safety conditions.
