description: This work is devoted to the assessment of the optimal testing period of the EPS channels in order to reduce the probability of system failure, as well as to identify those parameters that most significantly affect the determination of the optimal frequency of testing. Tasks that were solved during the research: 1. Study of materials with initial data on the reliability of NPP equipment and the principles of operation in BARS software; 2. Creation of a logical-probabilistic model of the system and assessment of its reliability; 3. Analysis of the sensitivity of the evaluation results to the values of the parameters used and the simulated events; 4. Analysis of the results obtained. Modeling of the channels of the system was carried out in BARS software. Calculations of the probability of system failure were performed at the specified parameters of equipment and personnel reliability. Based on the results of the work, the optimal period for testing the EPS channels was obtained, and the sensitivity of the probability of system failure to equipment reliability parameters and personnel errors was revealed.
