Research methods: 1. Mathematical modeling using the software package HotSpot; 2. Simulation numerical simulation using a three-dimensional geofiltration model built in Visual Modflow 2011.1; 3. Stationary field research; 4. Mathematical statistical analysis of the obtained data. Results and their novelty. 1. The HotSpot software package was adapted to the conditions of the FAQ and the forecast impact of the fire on the territory of the selected RNOs was performed, as well as the calculations of the impact on the environment during the accident during the operation of the NSC were performed. 2. According to the results of the study using the methods of mathematical modeling and capabilities of the software complex Visual Modflow 2011.1, the direction of movement of radioactive substances with groundwater from room 001/3 of the facility "Shelter" ChNPP to the unloading areas; 3. To predict the movement of air in the space under the NSC (distribution of radioactive aerosols) created a computer model that takes into account the existing physical phenomena and processes; 4. To study the state of the hydrogeological environment, a map of hydroisogypsum of the pressureless aquifer within the near zone of the FAQ was created. With the help of this map the directions of distribution of radionuclides with groundwater from PZRV "Pidlisny" are determined; 5. Analyzed and systematized information obtained as a result of research located on the territory of the FAQ, in order to further model their cumulative radiation effects on the environment in the Chernobyl Exclusion Zone and beyond.
