Evaluation of Reliability Indicators of Units of Unified Set of Technical Means at Nuclear Power Plants Using Information About Failures and Defects

Abstract

The article deals with the method of analyzing statistical data on failures to assess the reliability of units of the Unified Set of Technical Means (UCTM) at the Balakovo NPP. The calculations are carried out under a conservative assumption due to the lack of some data in the defect log. The analysis of the obtained data concerned the case of zero failures of some blocks during the observation period. The results show that these blocks are quite reliable to continue their operation.
