Performance of Multi-Probe Corrosion Monitoring Systems at the Hanford Site

Between 2007 and 2009, several different multi-probe corrosion monitoring systems have been designed and installed in high-level nuclear waste tanks at the U.S. Department of Energy’s Hanford Site in Washington State.  The corrosion monitoring systems have been installed in wastes with different chemistry types.  An ongoing effort during the same time period has generated non-radioactive simulants that are tested in the laboratory to establish baseline corrosion monitoring system performance and characterize data to allow interpretation of readings from the multiple corrosion monitoring systems.  Data collection from these monitoring systems has reached the point where the results allow comparison with the laboratory testing.  This paper presents analytical results from the corrosion monitoring system development program.
