Standard Test Method for Atom Percent Fission in Uranium and Plutonium Fuel (Neodymium-148 Method)

Journal Article · · Annual Book of ASTM
OSTI ID:7364417
Measurement of 148Nd by mass spectroscopy in irradiated U fuel with initial Pu content of 0 to 50 percent is described as a method for determination of burnup. A blended spike of 150Nd, 233U, and 242Pu is added to the sample, and then the Nd, U, and Pu fractions are separated from each other by ion exchange. The decontaminated Nd is mounted on a Re filament for mass analysis. The atom percent fission is directly proportional to the 148Nd-to-fuel ratio in the irradiated fuel.
