Summary The purpose of the work is to create a mathematical model of radiohydrogeological conditions of the Chernobyl Exclusion Zone using the Visual Modflow software package. The mathematical model that was created covers area 25 km long and 28 km wide. With the help of this model, predictions of the distribution of radionuclides with groundwater from radiation-hazardous objects to the areas of unloading into surface waters — the riverbeds of the Pripyat and Uzh rivers were made. With the help of a mathematical model the substantiation of the system of observation wells of radiohydroecological monitoring during construction and operation of SNFSF and ISF-2 spent nuclear fuel storage facilities and storage facilities located on the industrial site of ChNPP was performed. Also, the mathematical model allowed to perform the inverse hydrogeological problem — to determine the filtration parameters of soils according to the simulation of the distribution with groundwater of the Brion indicator, which was specially introduced into the aquifer. Forecasting is necessary to substantiate design, and management decisions to protect groundwater and surface water from radioactive contamination. |
