description: The subject of the graduate qualification work is "Safety analysis of a research reactor with natural circulation at the maximum design accident".The given work is devoted to studying an accident with loss of coolant (LOCA). Tasks that were solved during the study: 1. Studying the calculation code RELAP5. 2. Consideration of the formation of leaks on the lowering and lifting section in the above-pool space. 3. Selection of the test problem and its analytical solution. 4. Writing a program that simulates emergency processes. 5. Conducting a security analysis. The work was carried out on the basis of information provided by the chief process engineer of the RIK JSC "NIIAR" Uzikov Vitaly Alekseevich, who proposed the concept of a heat removal system without pumping and shut-off valves. For the study, a program was compiled in the calculation code RELAP5, simulating the first circuit of the research reactor, as well as an emergency situation with a rupture of the main circulation pipeline. The local hydraulic resistance coefficients of the core were obtained in a preliminary calculation using SolidWorks Flow Simulation. The coefficients of uneven energy release over the core were obtained in a preliminary calculation using the MCU-PTR. As a result, the operation of the hull research reactor in an emergency situation was analyzed. The rate of establishment of stable natural circulation for the removal of residual heat release from the core, the temperature of fuel rods in the maximum heat-stressed fuel assemblies is investigated.
