Description

Technical Field

[0001] The present invention relates to the technical field of nuclear power overhaul radiation protection control and management, and in particular to a nuclear power overhaul radiation protection control and management method and device. Background Art

[0002] Ensuring the safety of on-site operations during the overhaul of nuclear power units is the most fundamental requirement, among which radiation protection safety is an important control requirement to protect workers and the environment. For this purpose, nuclear power plants have set up corresponding departments and management systems, and set up radiation protection managers during overhaul to promote radiation protection supervision and management. The distribution, circulation, risk analysis and formulation of protection measures for radiation protection work during overhaul, as well as the circulation and control of the work process of workers, are realized through the nuclear power plant production management information system and the IRP radiation protection management system.

[0003] In order to ensure the safety control and evaluation of radiation protection during overhaul, multiple radiation risk performance assessment indicators have been set. Currently, radiation risk performance assessment indicators are stored in the management procedures and overhaul manuals, and relevant documents need to be consulted each time they are queried. The radiation protection personnel are responsible for querying, counting, and reporting the current actual values ​​of each indicator in the IRP radiation protection management system. Managers cannot understand the current status of the assessment indicators at any time, which is not conducive to management and decision-making.

[0004] Nuclear power plants classify radiation risks for work order tasks in radiation control areas according to the radiation sources that may be involved, adopt different radiation protection management for work order tasks with different radiation risks, and reflect the radiation risk levels and control plans in the work order management system and radiation work permit management system.

[0005] When it is necessary to understand the current approval status of the radiation work license and the status of the work order task with radiation risks, it is necessary to manually enter the corresponding system for manual query, which is not conducive to dynamic grasp of this information, nor is it conducive to centralized and unified management, and it is not possible to deploy personnel management and predict radiation risks in advance.

[0006] In the existing work order management system, there is a corresponding relationship between the maintenance equipment and the system to which it belongs, the site area, the elevation, etc. However, in order to understand the current working status, it is necessary to manually classify and query in the work order management system, which is very time-consuming and wastes human resources. At the same time, it is impossible to grasp the overall situation of radiation risk work in the radiation control area in the first time, which is not conducive to risk management, especially when the radiation level in a certain area changes, the radiation risk of personnel cannot be effectively controlled.

[0007] The information of staff entering and leaving the radiation control area can be reflected in the original software system. Through manual query, the current personnel information and elevation location of the radiation control area can be understood, but this important information cannot be displayed in real time and many staff cannot access it.

[0008] The original management and control method for important radiation protection information notifications was for the radiation protection manager to convey them through meetings or emails. This resulted in problems such as untimely information delivery and failure to cover all overhaul personnel.

[0009] The original radiation protection control methods have many unfavorable factors as mentioned above. The power plant management is unable to promptly identify important radiation control area work and existing important radiation work. Some personnel in the hierarchical control of radiation risk work are unable to pay attention to it, which may lead to ineffective radiation protection supervision and control, and even affect the economic benefits of the nuclear power plant. Summary of the invention
