Method for constructing working safety boundary of nuclear power plant

Abstract

The invention relates to the technical field of nuclear power plant operation management, and particularly discloses a method for constructing a working safety boundary of a nuclear power plant. The method specifically comprises the following steps: establishing isolation classification models of different systems and equipment of the nuclear power plant; establishing an isolation boundary of each system according to equipment characteristics of different systems of the nuclear power plant; determining isolation boundary priorities of different types of systems and the same type of systems; and according to isolation boundaries of different systems of the nuclear power plant, performing automatic isolation area demarcation and establishing an isolation instruction. According to the method, a nuclear power plant equipment isolation boundary model and an isolation boundary priority sequence are established, and equipment with defects is prevented from being used as an isolation boundary; meanwhile, the working safety boundary of the maintenance equipment or system is automatically formed according to the isolation boundary model and the isolation boundary sequence relation, the accuracy and integrity of the working safety boundary are improved, human errors are reduced, and the personnel safety, the equipment safety and the working safety of a nuclear power plant operation site are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant operation management, and in particular relates to a method for constructing a nuclear power plant working safety boundary. Background technique [0002] During the production and operation of the nuclear power plant, in order to ensure the reliable and stable operation of the equipment, some regular preventive maintenance work will occur, and some equipment defects will also occur. The completion of the preventive maintenance work and the elimination of defects need to be realized through on-site operations; These on-site works need to establish a clear safety boundary and delineate a safe environment to ensure the safety of personnel, equipment, and operations. The work safety boundary established is isolation. Isolation is to establish a clear breakpoint (that is, an isolation boundary) for a system or equipment from its associated process system, electrical system, and instrument c...
