A power plant isolation operation system and method for preventing human errors

Abstract

The invention relates to the technical field of human factor fault prevention of power plants, and particularly discloses a human factor fault prevention isolation operation system and method for a power plant, and the method comprises the following steps: (1) preparing isolation operation; (2) carrying out isolation operation; and (3) finishing the inspection and acceptance of the isolation operation. Technical prevention means for preventing human errors can be provided for on-site isolation operation, the probability of accidents caused by the human errors is reduced, meanwhile, monitoringof the management layer on on-site personnel behaviors is enhanced, and human resource management is enhanced.

Description

technical field [0001] The invention belongs to the technical field of preventing human errors in power plants, and in particular relates to an isolation operating system and method for preventing human errors in a power plant. Background technique [0002] In recent years, among various accidents in power plants, the probability of accidents caused by human error has always remained high. Strengthening human error management and standardizing employee behavior have become the focus of safety production in power plants, especially nuclear safety in nuclear power production. At present, there is a high probability of human error in the current implementation of isolation operations and release of isolation procedures. [0003] The main operations of the on-site implementation part of the isolation operation are setting positions, changing equipment status, and hanging / unlocking isolation card locks, which have the following defects: [0004] 1. The prevention of human errors...

AI Technical Summary

Problems solved by technology

[0004] 1. The prevention of human errors during the operation mainly depends on the conscious use of human error prevention tools by operators, which is highly subjective and cannot guarantee the strict use of human error prevention tools;

[0005] 2. There is a lack of management personnel monitoring the on-site isolation operation and monitoring the behavior of the operators;

[0007] 4. The current isolation operation needs to hang a paper isolation card. The paper isolation card may be damaged, lost, stained, or damaged or blurred in complex environments such as high temperature and high humidity on site, resulting in unreadable information on the isolation card Pick-up or paper separation cards are not recyclable, which will affect the work process;

[0008] 5. The label information of the isolation card cannot be updated. When a device is to serve as another isolation boundary, it needs to be hung with multiple isolation cards, which increases the risk of misinterpretation of the isolation card;

[0010] 7. Unusual equipment is difficult to locate. On-site operators need to spend a lot of time in the process of locating the equipment, which seriously affects the work progress. In the process of searching for equipment in the radiation control area of ​​the nuclear power plant, the on-site personnel may also be exposed to unnecessary exposure.
