description: Topic of the graduation thesis: "Calculation of the cyclic strength of DN100 regulating valve for the feed and boron control system." This work is dedicated to the calculation of the cyclic strength of DN100 regulating valve for the feed and boron control system. The following tasks were addressed during the research: 1. Provide a description of regulating valve designs. 2. Perform a simplified calculation of the cyclic strength of the regulating valve. 3. Perform numerical modeling of the fatigue damage of the regulating valve. The research was based on the provisions of the regulatory document PNPP G-7-002- 86. A simplified calculation of the cyclic strength was carried out, and the operating modes of the regulating valve were considered. Numerical modeling was conducted using ANSYS software to calculate the fatigue damage of the valve structure. Additionally, the application of the specialized Fatigue tool was examined to assess the cyclic strength of the valve structure. Based on the methodology of simplified calculation of cyclic strength and the operating modes of the regulating valve, the values of the amplitude of the equivalent local stress in the examined areas of the valve structure were determined, and the strength condition was checked. The calculation results were obtained for each individual operating mode as well as for the combined calculation cycle. It was found that the simplified methodology, numerical modeling, and Fatigue tool provided different results. The highest accumulated fatigue damage was obtained using the simplified calculation methodology. Additionally, it was found that the Fatigue tool allows for the evaluation of accumulated fatigue damage only for modes with a cycle count not exceeding 106 . If the cycle count exceeds 106 , the obtained results inaccurately reflect the value of accumulated fatigue damage in the valve structure. Based on the research results, it was determined that the most significant influences on the structure are the hydraulic testing, heating, and cooling modes.
