Complete equipment and method for nuclear power station identity recognition and electronic dosimeter gating

Abstract

The invention belongs to the field of nuclear power station radiation control area personnel access control and management. The invention particularly relates to complete equipment and method for nuclear power station identity recognition and electronic dosimeter gating. The equipment comprises an identity recognition module, a control screen, an electronic dosimeter read-write module, an interface module, a power supply module, a gate and a data management storage module, the identity recognition module is connected with the control screen, and the other end of the control screen is connectedwith the electronic dosimeter read-write module and the interface module. According to the invention, automatic personnel identity identification can be realized, the radiation control area personnelaccess entity isolation control is realized, and before entering the radiation control area, management and control personnel must start a portable electronic dosimeter to enter the radiation controlarea, so that a personal dose file is established, the personnel passing rate, the radiation dose management level, dose statistical analysis and subsequent radiation dose optimization management areimproved, and personnel radiation irradiation accidents are avoided.

Description

technical field [0001] The invention belongs to the field of personnel access control and management in a radiation control area of ​​a nuclear power plant, and in particular relates to a complete set of equipment and method for nuclear power plant identification and electronic dosimeter gate control. Background technique [0002] Nuclear power plants need to control and manage personnel entering and exiting the radiation control area. At present, the electronic dosimeter is activated and exited by the electronic dosimeter reading and writing device for manual management and control. The process of entering and exiting the radiation control area is: Long-term authorized personnel entering the radiation control area can enter the dressing room at the entrance of the radiation control area with a valid certificate. After changing and wearing the protective clothing in the radiation control area, they can insert their personal electronic dosimeter into the existing electronic do...

AI Technical Summary

Problems solved by technology

[0003] The existing radiation control area entry and exit management process relies on personnel consciously implementing the radiation control area entry and exit management system to achieve the purpose of control, but there are the following problems: personnel do not have any physical restrictions when they do not wear electronic dosimeters and do not activate electronic dosimeters , personnel can enter the radiation control area, which may cause the dose of personnel exposure to be unable to be counted and archived or cause radiation exposure events; personnel with long-term authorization to enter the radiation control area, who currently do not need to perform work tasks, can also enter without physical restrictions Radiation control area may cause unnecessary personnel dose exposure and personnel radiation exposure incidents may occur, and omissions in personnel dose management may occur; after the staff enters the radiation control area, if the previous work is over and the next work task needs to be performed, - It is impossible to change the work ticket number conveniently and in time, so that the radiation dose received by the personnel of each work cannot be counted separately. For the follow-up, the actual dose received by the personnel of each work cannot be counted, and the follow-up work dose sharing cannot be realized. and work dose optimization; by manually entering the 7-digit personnel certificate number and the ticket number for performing the work, the speed of starting the electronic dosimeter is slow and error-prone, which affects the pass rate when there are many people, and then affects the work progress; personnel enter and exit radiation The time and working hours in the control area cannot be counted, and it may also cause the information of personnel staying in the radiation control area to be unable to obtain, and there is a risk of personnel safety; the information of personnel entering and leaving the radiation control area is not stored in the database, and subsequent statistical analysis and dose optimization management cannot be performed
