Uranium and plutonium concentrations and isotopic abundances

Journal Article · · Annu. Book ASTM Stand.; (United States)
OSTI ID:5612335
The method is applicable to the determination of uranium (U) and plutonium (Pu) concentrations and their isotopic abundances in solutions which result from the dissolution of nuclear reactor fuels either before or after irradiation. A minimum sample size of 50 ..mu..g of irradiated U will contain sufficient Pu for measurement and will minimize the effects of cross contamination by environment U. The procedure is applicable to dissolver solutions of uranium fuels containing plutonium, aluminum, stainless steel, or zirconium. Interference from other alloying constituents has not been investigated and no provision has been made in the method for fuels used in the /sup 232/Th-/sup 233/U fuel cycle. The method includes a discussion of significance, apparatus, reagents, materials, instrument calibration, procedure, calculation, reporting, precision, and accuracy. (JMT)
