Abstract
The concentration and isotopic composition of uranium were determined in a solution of burnt WWER reactor fuel. The isotopic composition was determined by mass spectrometry, whereas for determining the concentration of uranium various methods were used. The interlaboratory mean square errors of the determination of uranium concentration by isotopic dilution analysis and by chemical methods were 0.37 and 1 rel.%, respectively, the content being 2.06 mg U/g fuel solution. The mean uranium concentrations obrained by both methods differ from each other by 1.04 rel.%.
