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

Embodiment 1

[0044] Nuclear power plant emergency state diagnosis system, including data input module, storage module, diagnosis module, guide module and display module:

[0045] The data input module is used to receive nuclear power plant status data and user input information representing the safety status of the nuclear power plant. External data such as events, analysis results, whether the emergency operation procedures are activated, and other situations that should enter the emergency state; the emergency state diagnosis system of the nuclear power plant has two data input methods, one is to receive the above nuclear power plant state data, and the other is to receive the above-mentioned nuclear power plant state data. The first is to receive the information input by the user on site, so that the system can support the user to directly input the status data of the nuclear power plant for subsequent judgment, which can be used for simulation, training, and research.

[0046] The stor...

Embodiment 2

[0054] On the basis of Embodiment 1, in this embodiment, the nuclear power plant emergency state diagnosis system also includes:

[0055] The alarm module is used to output an alarm signal based on the diagnosis result of the current emergency state level of the nuclear power plant obtained by the diagnostic module, and the alarm signal drives the voice alarm device and / or light alarm device connected to the system to give voice and / or light flashing prompts;

[0056] Recording module, used to record the user's operation on the system, the record can be output and printed in the form of text;

[0057] The data output module is used to output data according to user requirements.

Embodiment 3

[0059] On the basis of Embodiment 1 or Embodiment 2, the diagnostic module in this embodiment further includes: an identification class judgment module, an initial condition judgment module, a search module for emergency action levels, and an emergency state level diagnosis output module:

[0060] The identification class judgment module is used to judge whether the received nuclear power plant status data or user input information belongs to the identification class;

[0061] The initial condition judgment module is used to further judge the initial condition of the received nuclear power plant status data or user input information in the identification category;

[0062] The emergency action level search module is used to further search for the emergency action level corresponding to the received nuclear power plant status data or user input information under the corresponding initial conditions;

[0063] The emergency state level diagnosis output module judges the level of ...

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...
