description: The subject of the graduate qualification work is Â«Calculation of the hydraulic accumulator of ECCS of the nuclear power plant with VVER-1500Â». This work is devoted to the calculation and development of the ECCS design for nuclear power plants with VVER-1500. Tasks that were solved during the study: 1. Analyze and justify the ECCS scheme. 2. Calculate the NPP thermal scheme. 3. Conduct a thermal calculation of the core. 4. Calculate the actuation pressure of the hydraulic accumulator of ECCS. 5. Develop the design of hydraulic accumulator of ECCS.The work provides the choice of scheme and design of the hydraulic accumulator of ECCS based on various projects. The calculation of the NPP thermal scheme is carried out by the method of mathematical modeling using the CAD software "United Cycle". The main indicators of NPP thermal efficiency are obtained. The geometric characteristics of the reactor and the parameters of the coolant in the reactor circuit are determined. The method for calculating the actuation pressure of the hydraulic accumulator of ECCS in a single-element approximation is given. The change in the parameters of the reactor circuit during an accident with a large leak is analyzed. The strength calculation of the hydraulic accumulator of ECCS is given. Based on the data obtained, the design of the hydraulic accumulator is developed. The method for calculating the hydraulic accumulator given in the paper can be used for similar projects with other reactors.
