Auxiliary Judgment System and Method for Nuclear Power Plant Emergency State Based on Emergency Action Level

Abstract

The invention discloses a nuclear power plant emergency state auxiliary judgment system and method based on the emergency action level. The nuclear power plant emergency state auxiliary judgment method comprises the steps that the operation state and parameters of a nuclear power plant are automatically obtained by connecting interfaces of a nuclear power plant DSC, a nuclear power plant environment monitoring system and the like and combining an artificial data input module; a logic control module monitors the variation conditions of EAL related parameters in real time, carries out judgment according to built-in logical semantics and gives an EAL logic judgment process and judgment result; through the information such as EAL parameter monitoring, the logic judgment process, the logic judgment result and the suggest emergence state displayed in a visible user interface of the system, a prompt message when a parameter threshold condition is triggered and the emergence state changes is given in time; the system gives emergence state advice, emergence command staff carries out artificial interference, and the final emergence state is determined and issued through a platform. The nuclear power plant emergency state auxiliary judgment system and method based on the emergency action level provide effectively assistance means for correct judgment and decision making of nuclear power plant operators and the emergence command staff.

Description

technical field [0001] The invention relates to an auxiliary judgment system and method for effective emergency action level of a nuclear power plant in an emergency state. Background technique [0002] The possible nuclear accident emergency state caused by human error or failure of mechanical equipment in nuclear power plants cannot be completely avoided. Therefore, a nuclear power plant as an operating unit must have a complete set of management procedures for nuclear accident emergency preparedness and emergency response, and the emergency action level (EAL, Emergency Action Levels), which is one of the important contents of the on-site emergency plan, has been increasing since the 1970s. It has always attracted the full attention of many nuclear power countries and the international community. [0003] Emergency Action Levels (EAL, EmergencyActionLevels) are the basis for nuclear power plants to determine the emergency status level and the starting conditions for imple...

Problems solved by technology

At present, the judgment of the emergency state mostly relies on human judgment, and there is no systematic auxiliary judgment method. This application is developed and designed based on this background
