scope:

ISO 15366-1:2014 describes procedures to chemically separate andpurify uranium and plutonium in dissolved solutions of irradiatedlight water reactor fuels and in samples of high active liquidwaste of spent fuel reprocessing plants, prior to their isotopicanalysis by e.g. mass spectrometric method or alpha spectrometry.ISO 15366-1:2014 describes a technique for the separation ofuranium and plutonium in spent fuel type samples based onchromatographic method. The procedure applies to samples containing1 ?g to 150 ?g Pu (IV) and (VI) and 0,1 mg to 2 mg U (IV) and (VI)in up to 2 ml of 3 mol?l-1 nitric acid solution. It is applicableto mixtures of uranium and plutonium in which the U/Pu-ratio canrange from 0 up to 200.
