Experience acquired in developing and efficiently using information-and-analytical computer systems on the erosion-corrosion problem at the power units of the Balakovskaya nuclear power plant

The authors describe the structure and functional capabilities of the information-and-analytical computer systems used for monitoring and control of the erosion-corrosion state of elements of equipment and pipelines of the secondary circuit at the nuclear power plant (NPP) that have been developed and installed at the Balakovskaya NPP (BalNPP). This paper presents the results of estimating the erosion-corrosion categorization and determining the service life of elements of equipment and pipelines until they exhibit inadmissible thinning, as well as data obtained from the statistical analysis of the effectiveness of the in-service control (thickness gauging) of elements of pipelines of a secondary circuit by example of the power unit No. 1 of the BalNPP.
