Abstract
Uranium nitride is considered to be a possible fuel for fast reactors. Much of the research to date has targeted synthesis of uranium nitride. This work developed and optimized destructive assay procedures for fresh fuel characterization of trace impurities and isotopic analysis for chemical quality control of uranium nitride. Uranium nitride was completely digested followed by optimized column separations for 47 analytes quantified and percent recoveries calculated via ICP-MS. The strip solution containing uranium was isotopically measured along with a certified reference material to determine accuracy and precision of the isotopic measurement.
