Embodiment Construction
[0040] A method for supervising the performance of a main water supply system of a nuclear power plant, the method specifically includes the following steps:
[0041] Step 1. Determine the supervision scope of the main water supply system of the nuclear power plant;
[0042] According to the system equipment of the main water supply system of the nuclear power plant, the scope of supervision is determined to include the feedwater pump in the main water supply system, the main regulating valve of the main water supply pipeline, the auxiliary circuit regulating valve, the containment isolation valve, the hydraulic turbine inlet electric regulating valve, the main feedwater pump lubricating oil pump, The heater heats the steam condensation feed water pump;
[0043] Step 2. Monitor the main water supply system of the nuclear power plant to be supervised, and divide the supervision target level of the system or equipment to be monitored according to the monitoring data;
[0044] S...

Relating to the technical field of nuclear power station main water supply system reliability management, the invention particularly discloses a nuclear power station main water supply system performance supervision method. The method includes: step 1, determining a nuclear power station main water supply system supervision range; step 2, monitoring a to-be-supervised nuclear power station main water supply system, and grading the supervision goal of the to-be-supervised system or equipment according to monitoring data; and step 3, according to the supervision goal grade of the detection system or equipment, carrying out corresponding action plan. The method provided by the invention provides powerful data support for cause analysis by collecting and recording the historical data of the main water supply system and equipment performance, ensures system engineers continuous grasp of the system state and performance as well as the change condition through long-term tracking and evaluation of the main water supply system health condition, and at the same time provides input for continuous improvement of the main water supply system equipment reliability, thus being important basis forcontinuous improvement of equipment management.
Description
technical field [0001] The invention belongs to the technical field of reliability management of the main water supply system of a nuclear power plant, and in particular relates to a method for supervising the performance of the main water supply system of a nuclear power plant. Background technique [0002] The main water supply system is equipped with five electric main feed water pump sets (each main feed water pump has a capacity of 25%, and four uses and one standby when running at full power), and each evaporator water supply pipeline is equipped with 1 main water supply regulating valve, 1 One set of main feedwater isolation valve, one set of bypass regulating valve, one set of bypass isolation valve, and one set of containment isolation valve. When the unit is running at full power, 4 main feedwater pumps take water from the deaerator and send it to the water supply manifold before high-power addition. The main feed water enters the main feed water joint before the ...
