Problems solved by technology

[0003] However, the existing airborne radionuclide atmospheric diffusion calculation and analysis methods for nuclear power plants lack the comparison method between the regional scale grid airborne radionuclide diffusion characteristics and observation values
At present, the method usually used to compare the atmospheric diffusion characteristics of radionuclides is to obtain the simulated values ​​of observation points for single-point comparison, resulting in comparison results that can only reflect the local characteristics of airborne radionuclides, which is not conducive to the regional scale of airborne radionuclides. The spatial distribution of the atmospheric diffusion characteristics of airborne radionuclides at the regional scale is a key concern in the environmental impact assessment of nuclear power plants
There is no good verification method for regional-scale airborne radionuclide diffusion characteristics of nuclear power plants in the prior art

Abstract

The invention relates to the technical field of the radionuclide atmospheric diffusion environment influence evaluation of the nuclear power plant, in particular to a verification method for the regional scale gas-borne radionuclide diffusion characteristics of a nuclear power plant. The method comprises the following steps that: utilizing a known position nuclide activity value observed by the nuclear power plant to estimate a release point regional grid point nuclide activity value; utilizing an the estimated nuclide activity value to construct a distribution function; and comparing a difference between an estimated nuclide activity distribution function and an observed nuclide activity distribution function, comparing with a distribution function simulated by an atmospheric diffusion mode, and analyzing a matching degree between the simulated gas-borne radionuclide and the observation value. The method is scientific and reasonable and is an important technical means for evaluating the atmospheric environmental impact of the regional scale gas-borne radionuclide of the nuclear power plant.

Description

technical field [0001] The invention relates to the technical field of environmental impact assessment of radionuclide atmospheric diffusion of nuclear power plants, in particular to a method for verifying the regional scale airborne radionuclide diffusion characteristics of nuclear power plants. Background technique [0002] Airborne radionuclides are discharged into the environment through the atmosphere during operation or accidents of nuclear power plants, causing radiation impacts on the environment and the public. A method for calculating the atmospheric dispersion of airborne radionuclides in nuclear power plants is provided in the environmental impact assessment method for nuclear power plants. [0003] However, the existing airborne radionuclide atmospheric diffusion calculation and analysis methods for nuclear power plants lack the comparison method between regional scale grid airborne radionuclide diffusion characteristics and observed values. At present, the met...
