Flow Accelerated Corrosion in Fossil Fuel Power Plants
What is FAC?
A well-known source of problems in fossil fuel and nuclear powerplants is flow accelerated corrosion, also known as FAC. This kind of corrosion can occur when carbon steel piping and its components become degraded through the presence of steam water or flowing water that has low-dissolved oxygen.
FAC occurs when the normally protective oxide layer on the inside surface of low alloy steel and carbon piping dissolves. De-oxygenated water at elevated temperatures removes the naturally-formed iron oxides on the pipe’s exposed surface.
This thins the pipe wall, which can potentially cause leaks and catastrophic ruptures, negatively impacting both plant reliability and personnel safety.

PALO ALTO, Calif., May 25, 2021 /PRNewswire/ The Electric Power Research Institute (EPRI) has launched the new Distributed Energy Resource Value Estimation Tool (DER-VET™) to increase grid flexibility as more distributed energy resources (DER) are integrated into a cleaner electric grid.
The tool provides a free, publicly accessible, open-source platform for calculating, understanding, and optimizing the value of DER based on their technical merits and constraints. DER-VET was developed in collaboration with the California Energy Commission (CEC). DER-VET empowers developers, utilities, and regulators across the electric power industry to make better-informed DER application decisions based on a comprehensive, real-world dataset, said Daniel Brooks, Vice President of Integrated Grid and Energy Systems at EPRI.
