Development and Application of an Information-Analytic System on the Problem of Flow Accelerated Corrosion of Pipeline Elements in the Secondary Coolant Circuit of WER-440-Based Power Units at the Novovoronezh Nuclear Power Plant

摘要

Specific features relating to development of the information-analytical system on the problem of flow-accelerated corrosion of pipeline elements in the secondary coolant circuit of the WER-440-based power units at the Novovoronezh nuclear power plant are considered. The results from a statistical analysis of data on the quantity, location, and operating conditions of the elements and preinserted segments of pipelines used in the condensate-feedwater and wet steam paths are presented. The principles of preparing and using the information-analytical system for determining the lifetime to reaching inadmissible wall thinning in elements of pipelines used in the secondary coolant circuit of the WER-440-based power units at the Novovoronezh NPP are considered.
