Description
Technical Field

Background
With the implementation of national energy strategy, the nuclear power industry is developing vigorously, and meanwhile, the requirements of the supervision department on nuclear power safety are higher and higher. The operation department, as a direct responsibility department for the safe and stable operation of the power plant, needs to provide safe conditions for the maintenance of the facilities of the power plant by timely and accurately controlling the states of the system, the equipment, the components and the like, so as to ensure the production safety of the power plant in the production preparation and operation stages. This operational behavior of the operation department is called isolation, and specifically includes: operating some kind of running equipment, and cutting off or emptying a working source; closing or opening the equipment facilities and locking and disabling any operations on such equipment; hang tags, alert such devices of special functions and status, etc. The following conditions must be simultaneously fulfilled for the installation of the power plant to be able to serve as an isolation device: firstly, the separation work can be completely carried out; the other is that its isolated state can be forcibly locked. Generally, before a repair job is performed, a job of creating a work environment for the repair is called an isolation listing task; after the maintenance work is completed, the work of restoring the state of the equipment facilities before the maintenance is called an isolation deck-picking task. The isolation listing task and the isolation picking task are used as a preorder task and a postorder task of the work order task and form a complete process of maintenance work together with the work order task.
During the annual overhaul of the power plant, it is usually necessary to complete the implementation of tens of thousands of work orders in a short time, and before the implementation of the work activities, the relevant personnel are clear of the lessons obtained from the operation experience and the risk analysis results of the power plant, and countermeasures have been prepared for the problems which may occur significantly to reduce the potential risks. The information management system is simple and effective and is considered by people to ensure timely contact, coordination, approval and management of work activities. Device state changes to protect personnel, equipment, and the environment during work activities (e.g., hanging security tags) are effectively managed, enforced, and validated. Effective radioactive and pollution work control is implemented to maintain the radioactive dosage to be reasonable and feasible as low as possible, reduce the radioactive pollution of personnel and prevent unnecessary solid radioactive waste from being generated. Prior to work, knowledge of the radioactive environment conditions is sufficient to make appropriate decisions. Good working conditions are kept, industrial safety production management is adopted, and high-standard personal safety is realized.
Most of the work orders relate to equipment isolation, but due to the exclusive characteristic of the equipment facility state in a certain time period, the work orders are determined to be developed according to a certain plan, and the condition that the equipment state conflicts in a certain time period to influence the development of related maintenance work is avoided. The planning of these work orders directly affects the overhaul schedule and thus the production efficiency of the power plant. In order to ensure the reasonability and high efficiency of work order plan arrangement during overhaul, before overhaul, the reasonability of the current overhaul work plan can be checked through an isolation deduction model setting and conflict processing method, the conflict type of the equipment state is identified, and the plan, operation and maintenance departments are guided to optimize the overhaul work plan.
