Embodiment Construction

[0027] The preferred embodiment of the present invention will be described in detail below in conjunction with accompanying drawing:

[0028] Such as figure 1 The shown auxiliary judgment system for nuclear power plant emergency status based on emergency action level is mainly composed of EAL model 1, real-time data acquisition module 2, manual data acquisition module 3, logic control module 4, visual user interface 5, and EAL real-time database 8. Composition of large modules. The following is a further description of several modules:

[0029] Among them, EAL model 1 is parameters such as measured values ​​of certain instruments, state changes (input, failure) of specific equipment or systems, or severity of specific events (such as fires, security incidents, etc.) set according to specifications. The real-time data acquisition module 2 interfaces with the nuclear power plant digital control system (DCS) 6 and the nuclear power plant environmental monitoring system 7 to col...

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

[0001] technical field [0002] The invention relates to an auxiliary judgment system and method for effective emergency action level of a nuclear power plant in an emergency state. [0003] Background technique [0004] 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. As one of the important contents of the on-site emergency plan, the Emergency Action Level (EAL) Since then, it has always attracted the full attention of many nuclear power countries and the international community. [0005] Emergency Action Levels (EAL, Emergency Action Levels) are the basis for nuclear power plants to determine the emergency status level and the starting conditions for implementing corresponding emergency respons...
