GB/T 17229-1998大洋多金属结核矿产勘查规程

本标准规定了大洋多金属结核调查的基本内容、方法、样品测试和处理、试验测试技术和调查成果等技术内容。 本标准适用于大洋多金属结核勘查和室内的测试，对某些如铁锰结壳的调查也可参照使用。

DIN EN ISO 15366-1-2016核燃料技术.采用溶剂萃取色谱法对同位素和同位素稀释分析用的硝酸溶液进行铀和钚的化学分离和纯化.第1部分:微克范围内含钚的样品和毫克范围内含铀的样品(ISO 15366-1-2014).德文版本EN ISO 15366-1-2016

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.

DIN EN ISO 15366-2-2016核燃料技术.采用溶剂萃取色谱法对同位素和同位素稀释分析用的硝酸溶液进行铀和钚的化学分离和纯化.第2部分:纳克及以下范围内含钚和铀的样品(ISO 15366-2-2014).德文版本EN ISO 15366-2-2016

ISO 15366-2:2014 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 15366-2:2014 describes a slightly different separation technique from ISO 15366-1, based on the same chemistry, using smaller columns, different support material and special purification steps, applicable to samples containing plutonium and uranium amounts in the nanogram range and below. The detection limits were found to be 500 pg plutonium and 500 pg uranium.
