标准摘要
[中文适用范围]: ISO 15366 的这一部分描述了在通过质谱法(参见 ISO 8299)或α能谱法(参见 ISO 11483)进行同位素分析之前,对辐照轻水堆燃料溶解溶液和乏燃料后处理厂高活性废液样品中的铀和钚进行化学分离和纯化的程序。ISO 15366 的这一部分描述了一种基于色谱法分离乏燃料类样品中铀和钚的技术。该程序适用于在最多 2 ml 的 3 mol/L 硝酸溶液中含有 1 ng 至 150 µg Pu(V) 和 (VI) 以及 0.1 mg 至 2 mg U(V) 和 (VI) 的样品。它适用于铀和钚的混合物,其中 U/Pu 比值的范围为 0 至 200。 [外文原描述]: ISO 15366-1:2014 describes procedures to chemically separate and purify uranium and plutonium in dissolved solutions of irradiated light water reactor fuels and in samples of high active liquid waste of spent fuel reprocessing plants, prior to their isotopic analysis by e.g. mass spectrometric method or alpha spectrometry. ISO 15366-1:2014 describes a technique for the separation of uranium and plutonium in spent fuel type samples based on chromatographic method. The procedure applies to samples containing 1 μg to 150 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. It is applicable to mixtures of uranium and plutonium in which the U/Pu-ratio can range from 0 up to 200.
