description: This work is devoted to the development of a calculation method to ensure the integrity of concrete structures when exposed to a sodium fire, taking into account fire retardant materials. The object of research is a concrete structure with fire retardant materials. The subject of research is the temperature on the surface of a concrete structure, taking into account fire retardant materials. The non-stationary heat problem was solved by numerical simulation using the Â«ANSYSÂ» software package. The tasks that were solved during the study: 1. Solution of a test heat engineering problem to determine the fire resistance of a reinforced concrete structure by the loss of bearing capacity when exposed to a "standard" fire by numerical simulation; 2. Selection of the temperature distribution function from time to time in a sodium fire; 3. Development of a computational model, calculation of the structure for the effect of a temperature load from a sodium fire in the Â«ANSYSÂ» software, analysis of the results; 4. Analysis of methods of fire protection when exposed to burning sodium; 5. Selection of the optimal configuration of fire protection for the NPP premises. In the work, a numerical simulation of a sodium fire was carried out in the PC Â«ANSYSÂ». The results of the work are graphs of the temperature distribution on the concrete surface and over the section of the structure, depending on time. Conclusions are drawn on the use of various options for fire protection. On the example of the NPP premises, recommendations were given on the choice of materials with the optimal thickness to ensure the resistance of the structure in case of firÐµ.
