Nuclear power plant in-service inspection activity management method and system

Abstract

The invention relates to a nuclear power plant in-service inspection activity management method and system, and the method comprises the steps: S1, obtaining the basic information of all to-be-executed personnel, so as to build the corresponding relation between in-service inspection activities and the to-be-executed personnel; s2, obtaining inspection items of the in-service inspection activity to obtain corresponding execution personnel; s3, monitoring the execution process of the execution personnel for timing; s4, monitoring the radiation dose of the executor to obtain the corresponding radiation dose of the current day, judging whether the radiation dose exceeds the standard or not, if so, executing S5, and if not, executing S7; s5, generating a stopping instruction to trigger an executor to stop the current inspection process and end timing; s6, obtaining a new executor and executing the step S3; s7, monitoring the progress of the inspection item so as to end timing when the inspection item is completed; and S8, obtaining the sum of timing of all the execution personnel as the effective working hours of the in-service inspection activity and the sum of the radiation doses of all the execution personnel as the total radiation dose of the in-service inspection activity. By means of the method, it can be effectively guaranteed that the in-service inspection process is safely and smoothly carried out.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, and more specifically, to a method and system for managing in-service inspection activities of nuclear power plants. Background technique [0002] In-service inspection is one of the important maintenance activities during refueling and overhaul of nuclear power plants. Its function is to check the systems and components of nuclear power plants and confirm their safety status. The in-service inspection of nuclear power plants has the characteristics of a large number of work tickets, high risk in the working environment, high pressure on working hours, and a large number of inspectors. However, there is currently a lack of applicable management methods and systems to manage the overall project and the working hours of each job, Dose sharing situation, resulting in redundant or insufficient manpower arrangement, personal dose exceeding the standard and so on.
