The isolation problem of low-pressure feed water heater occurred in a nuclear power plant.The cause of the isolation problem was analyzed,and it was determined that poor drainage was the main cause of the isolation problem.Based on the actual situation of the equipment pipelines on site,practical and feasible treatment plans have been developed,including adding delayed filtering,adjusting the isolation liquid level of the heater,and adding emergency drainage pipes.After actual debugging and operation verification,the effectiveness of the treatment measures has been proven.
