Abstract
A structural scheme of the algorithm for calculating atmospheric emissions from nuclear power plants is presented. The additive model of the effective scattering area of the emission takes into account different components of the process: air ionization by radionuclides, turbulence and thermal inhomogeneities, aerosol particles, tracks of alpha-particles and meteorological formations of natural origin. Input data for calculations are meteorological data, radar parameters and interference situation in the region. As a result of calculations the field of spatial cross-sections of NPP emission into the atmosphere can be obtained and spatial characteristics of technogenic and natural meteorological formations can be specified (using radar data).
