Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0035] refer to figure 1 The invention provides a nuclear reactor accident mode identification and safety parameter estimation system, the system includes an accident mode identification module and an accident parameter estimation module, and the accident mode identification module is connected with the accident parameter estimation module. There are many types of reactor accidents (ie, accident 1, accident 2, etc.). The accident pattern recognition model first identifies the accident type, and then the accident parameter estimation model can call the accident parameter estimation model da...

Abstract

The invention belongs to the technical field of nuclear reaction accident analysis, specifically provides a nuclear reactor accident pattern recognition and safety parameter estimation system, and provides a nuclear reactor accident pattern recognition and safety parameter estimation method based on the system. The system response parameters of nuclear reactor accident sequences are used as training samples to train the accident pattern recognition model and the accident parameter estimation model respectively. The invention uses the artificial intelligence technology Logistic regression and BP neural network to scientifically, objectively, accurately and quickly identify the type of nuclear accident and estimate the safety-related parameters of the nuclear reactor system.

Description

technical field [0001] The invention belongs to the technical field of nuclear reaction accident analysis, and specifically provides a nuclear reactor accident pattern recognition and safety parameter estimation system, and a nuclear reactor accident pattern recognition and safety parameter estimation method based on the system. Background technique [0002] The nuclear reactor system has a complex structure. When a nuclear accident occurs, a series of complex physical and thermal responses will occur in the reactor core, the primary loop system, the secondary loop system and the specially designed safety system, and the change trend of system parameters has complex nonlinear characteristics. . In nuclear accident emergency or emergency drills, relying on human experience to manually judge the type of accident will not only be too subjective, but also fail to meet the requirements of rapid identification, and it is even less possible to use it in a relatively short period of...
