NUMERICAL MODELING OF THE DISTRIBUTION OF RADIONUCLIDES IN PORUS MEDIA FOR STRONG DAMAGE TO UNDERGROUND UNCLEAR POWER STATION

摘要

The distribution of radionuclides in the ground during the hypotheticla serious damage to an underground nuclear power station os considered. A set of filtration gas equations and convective diffusion equations are used to describe the transport of radionuclides. Processes of nuclear decay and nonequilibrium adsorption are taken into account. The results of mathematical modeling of the distribution of 90 and 137 isobaric radionuclide chains, and zones of probable pollution of the environment by these radionuclides, are presented.
