Human Error Prevention In Nuclear Power Station

In nuclear power industry, more than half of the security accidents are caused by human mistakes. This paper is to analyze the basic rule of human factor events, come about countermeasures to avoid human factor accidents, and minimize human factor accidents of nuclear power station effectively. This paper synthesized some domestic research and those aboard, classified the mistakes in nuclear power plant, and analyzed the characters, to the effect that we could adopt pertinent preventive measures according to different human error types.According the concept of safety management based on multiple-defense and the organizational behavior of safety and quality management, this paper has constructed a basic academic way to prevent the human error in nuclear power station.This paper has collected and analyzed great deal of human events in domestic nuclear plant and on the base of things happened in Daya Bay nuclear power station. To start with the analysis of the human error trend, we have studied on the main causes of human errors such as individual facts, external facts and decision-making facts etc. And the paper pointed out the key facts of human errors in the end. To begin with the study of people's mental behavior, we have found out the root cause of human error, ascertained the mode of human mistakes, and proposed some countermeasures to manage and avoid human errors.This paper concludes that by improving the system equipment, strengthening safety culture construction, deploying corresponding countermeasures, and advancing employees'safety sensitive and professional qualities, the human factor events could be reduced tremendously, and the plant could maintain safe operation.
