description: Topic of the final qualification work: "Probabilistic safety analysis of the emergency core cooling system (passive part)". This work is an analysis of the theoretical and practical aspects of the PSA - the emergency core cooling system (passive part). Research objectives: Study of methods of nuclear safety analysis; Considering the concept of probabilistic safety analysis; Considering and analyzing and analyze the emergency core cooling system (passive part); Comparison of analysis results. The work was carried out on the basis of the Leningrad NPP, where a significant part of the data was collected. Calculations were made to show failure probabilities. TopEvent FTA Express and PTC Mathcad Softwares were used to create mathematical models and analysis. As a result, the data that were obtained as a result of the calculations were interpreted by the method of quantitative and qualitative synthesis, comparative analysis, collection and processing of information on problematic issues.
