Problems solved by technology

Global warming has led to significant changes in meteorological conditions. The atmospheric diffusion characteristics of airborne radionuclides released by nuclear power plants and the resulting public exposure dose will be the focus of environmental impact assessment of nuclear power plants under future climate change scenarios. Technology does not yet have a good calculation method for nuclide atmospheric diffusion characteristics and public dose prediction under future weather scenarios of nuclear power plants

Abstract

The invention relates to the technical field of nuclide atmospheric environment influence evaluation under the future weather situation of a nuclear power plant, in particular to a prediction method for a public dosage caused by the nuclide under future weather situation of the nuclear power plant. The method comprises the following steps that: utilizing a random sampling method to generate a sitemeteorological factor field; utilizing the future weather situation to generate a regional site meteorological factor field disturbance quantity, and utilizing meteorological station random meteorological field data under current weather and future weather situations to drive an atmospheric diffusion model to generate atmospheric dispersion factors under current and future weather situations; andcomparing the public dosage caused by the nuclide under different orientations and different distances under the current weather and future weather situations. The method is scientific and reasonableand is an important technical means for predicting and analyzing the radionuclide atmospheric environment influence of the nuclear power plant.

Description

technical field [0001] The invention relates to the technical field of nuclide atmospheric environmental impact assessment under the future weather scenarios of nuclear power plants, in particular to a method for predicting public doses caused by nuclides under the future weather scenarios of nuclear power plants. Background technique [0002] Under normal operation or accident conditions of nuclear power plants, nuclides will enter the environment in the form of gases and aerosols. When airborne nuclides are discharged into the environment, they will be transmitted through dilution and diffusion in the atmosphere, thereby causing radiation impacts on the environment and the public. A method for calculating the atmospheric diffusion and dose impact of airborne radionuclides released from nuclear power plants is provided in the environmental impact assessment method for nuclear power plants. [0003] However, the existing atmospheric diffusion and dose calculation methods of ...
