  • Development and implementation of an effective and permanent solution for resolving flow-assisted corrosion problems in high- pressure turbine cross-under piping at the Krsko nuclear power plant
    Pelle, Michael ...
    Under certain conditions, the flow-assisted corrosion process can lead to catastrophic thinning of the walls in low-alloy steel pipes exposed to flowing water or wet steam. The rate of metal loss ... depends on complex interactions between factors such as water chemistry, pipe material composition and fluid dynamics. PCI Energy Services - a WEC Welding and Machining LLC / Westinghouse Electric company, developed a highly effective, reliable welding solution for permanently resolving flowassisted corrosion problems in turbine cross-under piping systems by applying a protective layer of austenitic stainless steel on the inner surface of these components. This technology was successfully implemented at a number of nuclear power plants in the US, and most recently at NEKćs Krško plant in Slovenia. Our paper describes this piping life-extension process, the engineering analysis performed by PCI/Westinghouse in order to support and validate it, and the steps leading to its successful implementation at Krško with a multi-cultural team consisting of American, Belgian, Slovenian and Croatian engineers and technicians.
