description: The topic of the final qualification work: Â«Calculation of cyclic strength of the control valve DN100 for the feeding system and boron regulation of the Tianwan NPPÂ». This work is the detection of fatigue damage of boron control valve for the 7th and 8th units of the Tianwan NPP. The objectives of the study were: 1. Design of control valves; 2. Simplified cyclical valve design calculation; 3. Numerical simulation of fatigue damage of valve structure. The work was carried out in the computational program Excel and in the computer program Ansys for modeling and analysis of fatigue valve damage. In the result of the study, the cyclic strength of the Tianwan NPP regulating valves of the 7th and 8th power units of DU100 was calculated. To determine the most loaded elements, a simplified method for calculating cyclic strength for PNAE G-7-002-86 was used. Flange studs do not meet cyclic strength requirements. It was therefore recommended to use different materials for flange studs. Numerical simulation was applied in the ANSYS software to characterize accumulated fatigue damage to valve design elements. In addition, the use of the Fatigue tool to assess the cyclic strength of the valve design was considered. According to the results of the studies it can be concluded that the most influence on the design are modes of hydraulic testing, heating and handling.
