Abstract

Two dimensional centrosymmetrical mathematical models and solving algorithm for interval differential equations of radioactive pollution transport in geological layers and biosphere with uncertainty consideration were developed for the purpose of radioactive waste depository (RWD) depressurization. There was developed the program system “DERAP” (Design of Radioactive Pollution), used for analysis of radioactive pollution (RP) transport in environment with uncertainty consideration. The program system was used for analysis of RP transport after RWD depressurization. Numerical assessments of forecast levels of radioactive biomass pollution have shown that the value of radiation dose significantly depends on the following factors: periods of half-decay of radioactive pollutions; ratio of diffusion of radioactive pollutions from the store; advection of pollutions along the Earth surface, depending on hydrodynamic characteristics of underground waters. Computing experiments were made to establish functional relations between model prediction and model parameter values.
