steam generator

The article focused on the development of information technology for the optimization of control over complex dynamic systems at the stage of their design that should realize possibilities of modeling of linear and nonlinear dynamic systems, the analysis and synthesis of such systems, their optimization on various quality criteria. The purpose of this article is to develop the structure and elements of information technology to optimize the control of complex dynamic systems, including automated control systems.

This paper represents the mechanism for corrosion damages of heat exchanging tubes (HET) of a steam generator PGV-1000 for various operational conditions. It was determined that corrosion damages locate mainly at the bottom of the steam generator bundled tubes. An investigation into the corrosion damages of HET was conducted in terms of PGV-1000 steam generator. The results of eddy-current testing (ECT) for steam generator HET performed by two different ECT systems “TEDDY-8”, “MIZ-30” were analyzed and compared to the results of metallographic examination of defects.
