description: This work is devoted to optimizing the program of non-destructive testing of pipelines of the primary coolant system of nuclear power plants using a risk-oriented approach within the framework of probabilistic safety analysis. During the work, the following tasks were solved: 1. Analysis of primary circuit pipelines for dominant degradation mechanisms and areas subject to non-destructive testing. 2. Definition of safety systems involved in emergency scenarios and their success criteria. 3. Analysis of the reliability of safety systems. 4. Modeling of emergency scenarios using the method of event trees and fault trees. 5. Categorization of pipelines according to the degree of risk of a severe accident. 6. Issuing recommendations on the mandatory number of non-destructive testing zones. 7. Analysis of risk changes. 8. Creation of a methodology for managing risk changes. As a result of the work, recommendations were issued on the minimum required number of control zones for pipelines of the first circuit of the NPP, considering the changing risks of core damage and a large emergency release. A method for managing risk changes was also proposed and a program was created in Python to automate risk analysis and implement multivariate calculations of the optimal number of control zones based on it.
