Nuclear power plant system supervision method based on ERDB

Abstract

The invention relates to the technical field of nuclear power plant equipment reliability management, and specifically discloses a nuclear power plant system supervision method based on ERDB. The supervision method comprises the steps that 1 the supervision scope of a nuclear power plant system is determined to form a system supervision list; 2 the performance target level of the system supervision list is classified according to the health status of the nuclear power plant system or equipment; 3 a system notebook module is used to automatically generate and query the supervision data of the system; and 4 system supervision is carried out on the nuclear power plant system or equipment. According to the method, system and equipment important for nuclear safety and power generation are identified through system function analysis; through failure mode and effect analysis (FMEA), the degradation mechanism and monitoring parameters of the equipment are identified; the degradation of the equipment is found and predicted in advance through monitoring and trend analysis of the parameters; and corresponding corrective actions are taken in time to improve the reliability of the equipment toensure the safe operation of a power station.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant equipment reliability management, and in particular relates to an ERDB-based nuclear power plant system supervision method. Background technique [0002] Nuclear power is a clean, efficient and high-quality modern energy source. China adheres to the principle of attaching equal importance to development and safety, implements the policy of safe and efficient development of nuclear power, and adopts the most advanced technology and the strictest standards to develop nuclear power. By the end of 2015, the number of nuclear power plants under construction in my country ranked first in the world, and it is estimated that the installed capacity of nuclear power plants in operation in mainland China will reach 58 million kilowatts by 2020. While nuclear power increases energy for the development of the national economy, its safety performance cannot be ignored. A nuclear power plant is a h...
