This part of ISO 15366 describes procedures to chemically separate and purify uranium and plutoniumin dissolved solutions of irradiated light water reactor fuels and in samples of high active liquid wasteof spent fuel reprocessing plants, prior to their isotopic analysis by e.g. mass spectrometric method (seeISO 8299[1]) or alpha spectrometry (see ISO 11483[2]).This part of ISO 15366, describes a technique for the separation of uranium and plutonium in spent fueltype samples based on chromatographic method. The procedure applies to samples containing 1 μg to150 μg 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. Itis applicable to mixtures of uranium and plutonium in which the U/Pu-ratio can range from 0 up to 200.
