description: This work addresses the determination of the stress-strain state and strength of the filtering equipment of the backup pump at a nuclear power plant using the finite element method. The first chapter presents the problem statement, defines the components of the structure, and describes all necessary material characteristics and strength evaluation criteria. The second chapter includes the calculations for hydraulic test pressure and the selection of the main dimensions of the body. In the subsequent chapters, force calculations, static strength calculations, and the determination of the temperature field of the filter element for all modes of operating conditions are conducted. Additionally, natural frequencies were determined, and the vibration strength of the equipment was assessed.
