Abstract

Corrosion-related failures in electric power plants often stimulate research aimed at understanding the cause of the failures and at developing cost-effective corrosion control options. This paper describes some of the success stories. Over the last few years, EPRI has helped solve several aqueous corrosion problems using the following approaches: materials selection, coatings, water chemistry control, residual stress modification and corrosion monitoring. These approaches were applied successfully to flue gas desulfurization systems, low pressure steam turbines and boiling water reactor piping. A measure of the success of these corrosion control options is the cost savings of over $570 million documented by only seven of EPRI's over 700 utility members after applying these techniques.
