Multi-risk comprehensive assessment system and method for nuclear power plants based on information fusion

Abstract

The invention discloses a multi-risk comprehensive assessment system for nuclear power plants based on information fusion, which includes a data acquisition module, a risk assessment module, a risk classification and early warning module, and a man-machine display module which are connected in sequence. Also disclosed is a multi-risk comprehensive assessment method for nuclear power plants based on information fusion, including the following steps: first, a data acquisition module collects nuclear power plant risk information, basic information of nuclear power plants, and information about population density and population age composition around the nuclear power plant site; Simulate and evaluate the event information that may endanger the safety of the nuclear power plant, the radiation risk information that may cause radiation leakage, and the personal maximum radiation dose and lethal dose during the life of the nuclear power plant in the future, and send the above calculation results to the risk classification and early warning module for classification and judgment. to the HMI display module. The present invention applies the multi-source information fusion technology in the field of nuclear power plant risk assessment and measurement, so as to evaluate the nuclear power plant risk well.

Description

technical field [0001] The invention relates to the field of safety evaluation of nuclear power plants, in particular to a multi-risk comprehensive evaluation system and method for nuclear power plants based on information fusion. Background technique [0002] Nuclear power is an important part of the power industry system and one of the important energy sources used by human beings. Nuclear power itself has many advantages. In today's increasingly serious international and domestic environmental problems, actively developing and promoting the construction of nuclear power plant projects is of great significance to the adjustment of my country's energy structure. However, nuclear power plants have the characteristics of being very complex and highly difficult. There are many factors that affect the operational risks of nuclear power plants, such as the geological conditions of the site, nearby meteorological conditions, hydrological conditions, and the conditions of the nucl...

AI Technical Summary

Problems solved by technology

However, the current risk assessment of nuclear power plants lacks systematic analysis and demonstration, and most of the nuclear power risk assessments are based on a single factor. There is no in-depth discussion on whether the comprehensive influence of various factors will pose a new threat to the safety of nuclear p
