The Defense Waste Processing Facility under construction at the Savannah River Plant will immobilize the radioactive waste generated by nuclear fuel processing in a borosilicate glass matrix. The ferrous-ferric ratio of the glass is a measure of its redox state, and balanced redox conditions in the glass melter are required for proper melter operation. Measurement of the Fe/sup 2 +//Fe/sup 3 +/ ratio by /sup 57/Fe Moessbauer spectroscopy has been a valuable research tool in the development of the DWPF process. The measurement techniques and data analysis will be described. Results on synthetic DWPF glass and on small-scale radioactive glass will be presented.
