Access authorization management system and management method of nuclear power plant control area

Abstract

The invention relates to an access authorization management system and management method of a nuclear power plant control area. A control area access authorization platform of the access authorizationmanagement system is respectively connected with a training center database server, a medical evaluation database server, a dose declaration information server, and a WBC measurement information server and obtains staff reference data of the training center database server, the medical evaluation database server, the dose declaration information server and the WBC measurement information server,and the control area access authorization platform is connected with a personnel information acquisition terminal and obtains personnel information collected by the personnel information acquisition terminal; and the control area access authorization platform calculates the authorization validity period for the corresponding staff to enter and exit the nuclear power plant control are according tothe obtained reference data and thee personnel information, and the authorization validity period is sent to a control area access control system. According to the access authorization management system, intelligent control of access of the nuclear power plant control area is realized, the efficiency of authorization is improved, the enterprise production cost is reduced, interconnection and interworking of personnel, authorization information and abnormal information are realized, and authorization safety management and the control level in the nuclear power plant control area is improved.

Description

technical field [0001] The invention relates to the field of nuclear power plants, and more specifically relates to a management system and a management method for access authorization in a control area of ​​a nuclear power plant. Background technique [0002] The authorization management of passage in the control area of ​​the nuclear power plant is mainly aimed at the authorization management for the radioactive staff in the nuclear power plant to enter and exit the control area of ​​the nuclear power plant. For the conditions of the four permits for dose declaration, the power plant has passed the audit, and the control area is authorized to pass, and the pass is printed, and the verification personnel are verified at the entrance and exit of the control area. [0003] The application, approval and granting of access authorization for the existing nuclear power plant control area are all controlled by manual entry and review, and paper access. On-site abnormal situation ...
