IAPWS have just released their White Paper on Corrosion Product Sampling, Monitoring and Analysis for Flexible and Fast Starting Plants.
The paper has been written and revised by the Power Cycle Chemistry (PCC) Working Group and is targeted at plants who have historically struggled to profile their corrosion product generation and transport because their operational profile has made understanding the inevitably high corrosion product concentrations difficult to understand.
The document includes the results from two IAPWS International Collaboration Projects conducted by Maja Skou Jensen and Mads Skovbjerg under the guidance of Karsten Thomsen with plant monitoring in Denmark, Australia, UK and the US. It should be noted that this White Paper is a "work in progress" document, so the PCC Group are always on the lookout for more data and comments to help improve before the paper is issued as a formal Technical Guidance Document.
This is a very exciting development which for the first time in power plant chemistry allows plants and operators to not only monitor the corrosion products using proxy techniques but also provides advice and guidance, through the new IAPWS Decay Map, to plants on whether their normal operating chemistry and shutdown procedures are optimum or can be improved.
