description: The final qualification work is devoted to modeling the temperature state of spent fuel assemblies using the KORSAR calculation code. The design of the spent fuel pool and fuel assemblies is considered. The scenario of the development of a category 3 accident with a leak from the spent fuel pool or a rupture of the pipeline, leading to a decrease in the water level in the pool, was considered, thermal hydraulic calculations were carried out for the spent fuel pool, the main geometric parameters of the rack cell were determined, the temperature distribution by height and cross-section of the fuel element for different water levels in the spent fuel pool was obtained. The time during which the fuel assembly with maximum energy release is drained was determined. The process in the KORSAR RC was modeled, the results were analyzed and a conclusion was made on the applicability in further calculations of the time to eliminate the accident.
