description: The topic of the final qualifying work: "Substantiation of the thermal reliability of the core of a research reactor with natural circulation of a coolant". This work is devoted to determining the temperature fields of the most energetically stressed fuel assemblies of the VVR-KN type and the reserve before the boiling crisis in the research reactor with a capacity of 25 MW in nominal conditions. Tasks that were solved during the work: 1. Analysis of the design of a 25 MW research reactor with natural coolant circulation. 2. Determination of the flow rate of the natural circulation of the coolant. 3. Calculation of temperature fields of the most energetically stressed fuel assembly. 4. Determining the reserve before the boiling crisis. The initial data were obtained during an internship at the research reactor complex of JSC "SSC RIAR". The work is based on the innovative concept of a reactor research facility proposed by the Russian specialist Uzikov V. A. As a result of the work, the thermal reliability of the active zone of the research reactor with natural circulation of the heat carrier was substantiated.
