Nuclear power plant emergency state diagnosis system and diagnosis method

Abstract

The invention discloses a nuclear power plant emergency state diagnosis system and an emergency sate diagnosis method. The system comprises a data input module for receiving data, representing a safety sate of a nuclear power plant, and user input information, a storage module for storing system data of the nuclear power plant, a diagnosis module for performing a logical judgment according to the nuclear power plant state data or the user input information to obtain a diagnosis result of a current state of the nuclear power plant, a guide module for performing a logical judgment according to the diagnosis result to obtain data to which attention should be further payed and then to search a next operation suggestion, and a display module for displaying the diagnosis result, the data to which the attention should be further payed and the next operation suggestion. The system and method can rapidly give a suggestion for the nuclear power plant emergency state grade, other indications and parameters which a user should continuously concern and which represent the nuclear power plant safety sate, and the next operation suggestion; and a more timely, objective and accurate emergency state grade diagnosis result is provided for a nuclear power plant accident emergency command reference.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant emergency planning and preparation, in particular to a nuclear power plant emergency state diagnosis system and an emergency state diagnosis method. Background technique [0002] At present, my country's emergency decision-making system for nuclear accidents in nuclear power plants mainly includes two aspects. The second is an "emergency decision-making support system" that predicts radioactive consequences based on accident radioactive source items and meteorological data, and makes judgments on intervention measures such as concealment, evacuation, taking iodine tablets, and relocation. [0003] Since the initial conditions and emergency action levels of my country's nuclear power plants are basically presented in the form of a matrix table, there are complex logical relationships among the identification categories, initial conditions, and emergency action levels. With the developmen...

Problems solved by technology

[0003] Since the initial conditions and emergency action levels of my country's nuclear power plants are basically presented in the form of a matrix table, there are complex logical relationships among the identification categories, initial conditions, and emergency action levels. The progress of the nuclear accident, this logical relationship is more complicated

When a nuclear accident occurs in a nuclear power plant, the emergency command needs to judge this complex logical relationship in the form of a matrix table to determine the emergency state level that the nuclear power plant should enter. This subjective manual judgment method is likely to make the emergency command Making wrong judgments or missing the best time to announce the level of emergency status leads to the problem of relying too much on the subjectivity of emergency command in the event of nuclear accidents in nuclear power plants, and unable to judge the level of emergency status in a timely, objective and accurate manner
