Direct spectroscopic investigations of metal oxide solubility and metal transport in supercritical water
FY 2010-11
Summary
The objective of the proposed research is to experimentally derive a consistent set of thermodynamic properties for transition metal solutes which can be used to predict corrosion product transport and deposition in supercritical water reactors. To this end, in situ x-ray absorption spectroscopy (XAS) will be used to obtain new data on the stability and structure transition metal species in supercritical water. The XAS data will be combined with solubility measurements obtained by direct x-ray fluorescence (XRF) spectroscopic measurements of selected metal oxide-water systems at elevated temperatures. This research seeks to gain a fundamental understanding of the physical and chemical mechanisms at the molecular scale in high temperature water systems. The anticipated results of the project are needed to specify appropriate chemistry control strategies or to develop other methods to mitigate the effects of corrosion product transport in GEN IV supercritical water reactors.
