GB/T 17229-1998大洋多金屬結核礦產勘查規(guī)程

本標準規(guī)定了大洋多金屬結核調查的基本內容、方法、樣品測試和處理、試驗測試技術和調查成果等技術內容。 本標準適用于大洋多金屬結核勘查和室內的測試，對某些如鐵錳結殼的調查也可參照使用。

DIN EN ISO 15366-1-2016核燃料技術.采用溶劑萃取色譜法對同位素和同位素稀釋分析用的硝酸溶液進行鈾和钚的化學分離和純化.第1部分:微克范圍內含钚的樣品和毫克范圍內含鈾的樣品(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核燃料技術.采用溶劑萃取色譜法對同位素和同位素稀釋分析用的硝酸溶液進行鈾和钚的化學分離和純化.第2部分:納克及以下范圍內含钚和鈾的樣品(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.
