Description
The determination of uranium in HLLW by double isotope dilution mass spectrometry is described. Uranium is separated from HLLW by TBP/Kel-F reversed-phase partition chromatography. The spikes are enriched in 235U and 238U, respectively. The relative standard error is better than 0.1% for the determination of uranium isotope abundance ratio by mass spectrometry. The blank value of whole procedure is 3 x 10-9 g and the detectable limit of the method is 1 x 10-9 g for uranium. The uncertainty of the determination is 2% for uranium content in HLLW
