ASTM C1816-2016 同位素丰度和含量分析前对含铀, 镅和钚的小容量样本进行离子交换分离的标准实施规程
简介：5.1x00a0;Uranium and plutonium are used in nuclear reactor fuel and must be analyzed to ensure that they meet acceptance criteria for isotopic composition as described in Specifications C833 and C1008. The criteria are set by mutual agreement between the manufacturer and end user (or between buyer and seller). This standard practice is used to separate chemically the isobaric interferences from 238U and 238Pu and from 241Am and 241Pu, and from other impurities prior to isotopic abundance determination by TIMS. 5.2x00a0;In facilities where perchloric acid use is authorized, the separation in Test Method C698 may be used prior to isotopic abundance determination. Uranium and plutonium content as well as isotopic abundances using TIMS can be determined by using this separation practice and by following Test Methods C698, C1625, or C1672. 1.1x00a0;This practice is an alternative to Practice C1411 for the ion exchange separation in small mass samples (~5 x03bc;g of plutonium and up to 0.5 mg of uranium in 1 mL of solution) of uranium and plutonium from each other and from other impurities for subsequent isotopic abundance and content analysis by thermal ionization mass spectrometry (TIMS). In addition to being adapted to smaller sample sizes, this practice also avoids the use of hydrochloric acid (HCl) and hydrofluoric acid (HF) and does not require the use of two anion exchange columns as required in Practice C1411. 1.2x00a0;In chemically unseparated samples isobaric nuclides at mass 238 (238U and 238Pu), and mass 241 (241Pu and 241Am) will be measured together thus compromising the accuracy of the results of isotopic composition of Pu. Therefore, chemical separation of elements is essential prior to isotopic analyses. Concentrations and volumes given in the paragraphs below can be modified for larger sample sizes, different types of anion exchange resin, etc. 1.3x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1845-2016 在以电感耦合等离子体质谱法 (ICP-MS)进行的同位素分析中使用高压离子色谱法 (HPIC) 从铀矩阵中分离镧系元素的标准实施规程
简介：5.1x00a0;The measurement of isotopic distributions for the lanthanide series elements is of important to all phases of the nuclear fuels cycle. Examples include the purification of the Nd isotopes from Ce and Sm isotopes for the determination of atom percent fission through the production of 148Nd in irradiated nuclear fuels using Practice C1769, determination of rare earth content and isotopic distribution in Uranium Ore Concentrates (UOC) for source term and production of lanthanide fission products in irradiated nuclear fuels for determination of performance, improvements of depletion codes, and analysis of burnup indicators.3 1.1x00a0;This practice provides instructions for the rapid separation of lanthanide elements using high pressure ion chromatography (HPIC) from dissolved uranium materials such as: nuclear fuels, uranium ores, hydrolyzed UF6, and depleted, natural, or enriched oxides/powders, or metals. When optimized, this technique will produce purified elemental fractions of the lanthanide elements isolated from the bulk uranium matrix allowing for isotopic assay using inductively coupled plasma mass spectrometry (ICP-MS). 1.2x00a0;This practice is most applicable for analyte concentrations of nanograms per gram uranium or higher. For ICP-MS detection and measurement of analyte concentrations lower than this, it would be necessary to perform additional pre-cleanup or concentration techniques, or both, which are not addressed in this practice. 1.3x00a0;When combined with isotope dilution, this practice can also be used for improved precision assays of the lanthanide elements using the principle of isotope dilution mass spectrometry (IDMS). 1.4x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this practice. 1.5x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1769-2015 为测定选定同位素以及评估燃料燃耗的废核燃料分析的标准实施规程
简介：5.1x00a0;This standard practice defines a measure of heavy element atom percent fission from which the output of heat during irradiation can be estimated. 5.2x00a0;This standard practice is restricted in use to samples where accurate pre-irradiation U and Pu isotopic analysis is available. This data should be available from the fuel manufacture. 5.3x00a0;The contribution of 238U fast fission is not subject to measurement from isotopic analysis. For reactors in which the majority of fissions are caused by thermal neutrons, the contribution may be estimated from the fast fission factors, x03b5;, found in each reactor design document. 5.4x00a0;In post-irradiation isotopic analysis, take extreme care to avoid environmental uranium contamination of the sample. This is simplified by using sample sizes in which the amount of each uranium isotope is more than 1000 times the levels observed in a blank carried through the complete chemistry and mass spectrometry procedure employed. 5.5x00a0;Take care to make sure that both the pre-irradiation and the post-irradiation samples analyzed are representative. In the pre-irradiation fuel, the 235U and 236U atom ratio content may vary from lot to lot. 236U is not found in naturally uranium in measurable quantity (<2 ppm of a u basis) but forms during irradiation and increases with each successive pass through the fuel cycle. In the post-irradiation examination of a large fuel element, the atom percent fission normally varies radially and axially. Radial and axial profiles of atom percent fission can be determined by analyzing samples obtained from along the radius or axis of the fuel element. An average value of atom percent fission can be obtained by totally dissolving the fuel to be averaged, and then mixing and analyzing an aliquot of the resultant solution. 5.6x00a0;The burnup of an irradiated nuclear fuel can be determined from the amount of a fission product formed during irradiation. Among the fission products, 148Nd has the following properties to recommend it as an ideal burnup indicator: (1) It is not volatile. (2) It does not migrate in solid fuels below their recrystallization temperature. (3) It has no volatile precursors. (4) It is nonradioactive and requires no decay corrections. (5) It has a low destruction cross section. (6) Formation of 148Nd from adjacent mass chains can be corrected for. (7) It has adequate emission characteristics for mass analysis. (8) Its fission yield is nearly equivalent for 235U and 239Pu. (9) Its fission yield is essentially independent......

ASTM D7026-2013 通过碳同位素分析测定材料的生物基含量的测定结果的抽样和报告用标准指南
简介：4.1x00a0;The carbon isotope analysis is designed to be an adjunct to other information in determination of biobased content, specifically the manufacturerx2019;s records. It is also a means of verifying the authenticity of a disputed lot of material which may be manufactured by different means, from different raw materials. FTIR or other chemical analysis means will identify the molecule as being ethanol, but not give indication of the source (that is, fossil carbon versus modern carbon). The carbon isotopes will give both indication of source and the presence of a mixture of sources. 4.2x00a0;Representative sampling and handling methods are clearly a prerequisite to obtaining accurate results from the radiocarbon composition determination and any other quantitative analytical method. 4.3x00a0;This guide provides for accurate and complete reporting of the sample collection, handling, chain of custody, sample preparation and treatment that allows any independent party to assess the validity of the reported biobased content of the material. 1.1x00a0;This guide provides a framework for collecting and handling samples for determination of biobased content of materials by means of the carbon isotope method described in Test Methods D6866. Tests for sampling adequacy based on the standard statistical tools are provided. In addition, reporting of the results, including sampling techniques and handling procedures and chain-of-custody issues are discussed. 1.2x00a0;This guide is concerned with collecting representative samples within a given material or a lot, not with lot-to-lot variations such as considered in quality control schemes. 1.3x00a0;Biobased materials often represent sampling problems specific to a given material, such as heterogeneity, and so forth, which require employment of material-specific sampling methods. The use of specialized sampling methods already accepted and validated by industries that manufacture and/or use the biomaterial is encouraged. However, all sampling techniques, especially non-standard techniques developed for specific materials must be reported in sufficient detail to allow critical assessment of the techniques used. 1.4x00a0;Carbon isotope analysis involves thermal processing in presence of oxidants. Compatibility of any given material with Test Methods D6866 must be assessed. Special attention must be given to materials with potential for explosion hazards, such as peroxides, nitrated compounds, azides, and so forth. Examples of peroxide-forming compounds are ethers, some ketones and a number of other compounds. 1.5x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

ASTM C1411-2014 同位素分析前铀和钚离子交换分离的标准操作规程
简介：5.1x00a0;Uranium and plutonium are used in nuclear reactor fuel and must be analyzed to insure that they meet certain criteria for isotopic composition as described in Specification C833 and Specification C1008. This standard practice is used to chemically separate the same mass peak interferences from uranium and plutonium and from other impurities prior to isotopic abundance determination by thermal ionization mass spectrometry. 5.2x00a0;In those facilities where perchloric acid use is tolerated, the separation in Test Method C698 may be used prior to isotopic abundance determination. Uranium and plutonium concentrations as well as isotopic abundances using thermal ionization mass spectrometry can be determined using this separation and following Test Method C1625. 1.1x00a0;This practice is for the ion exchange separation of uranium and plutonium from each other and from other impurities for subsequent isotopic analysis by thermal ionization mass spectrometry. Plutoniumx2013;238 and uraniumx2013;238, and plutoniumx2013;241 and americiumx2013;241, will appear as the same mass peak and must be chemically separated prior to analysis. Only high purity solutions can be analyzed reliably using thermal ionization mass spectrometry. 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3x00a0;This standard may involve hazardous material, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C1428-2011 用单支标准气体源多收集器质谱仪法进行六氟化铀的同位素分析的标准试验方法
简介：Uranium hexafluoride is a basic material used to produce nuclear reactor fuel. To be suitable for this purpose, the material must meet criteria for isotopic composition. This test method is designed to determine whether the material meets the requirements described in Specifications C787 and C996.1.1 This test method is applicable to the isotopic analysis of uranium hexafluoride (UF6) with 235U concentrations less than or equal to 5 % and 234U, 236U concentrations of 0.0002 to 0.1 %. 1.2 This test method may be applicable to the analysis of the entire range of 235U isotopic compositions providing that adequate Certified Reference Materials (CRMs or traceable standards) are available. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety health practices and determine the applicability of regulatory limitations prior to use.

EN ISO 15366-2-2016 核燃料技术-用溶剂萃取色谱法分离和提纯硝酸和铀同位素中的铀和钚同位素和同位素稀释分析-第2部分:在毫微克以下含有钚和铀样品(ISO 15366-2:2014)
简介：Dieser Teil von ISO 15366 beschreibt Verfahren zur chemischen Trennung und Reinigung von Uran und Plutonium in Lösungen von bestrahlten Leichtwasserreaktorbrennstoffen und Proben von hochaktiven Flüssigabfällen aus Brennstoff-Wiederaufbereitungsanlagen, bevor die Isotopenanalyse z. B. durch Massenspektrometrie- (siehe ISO 8299) oder Alphaspektrometrieverfahren (siehe ISO 11483) durchgeführt wird. Dieser Teil von ISO 15366 beschreibt ein Trennverfahren, das sich leicht von dem nach ISO 15366-1 unterscheidet; es basiert auf den gleichen chemischen Grundlagen, aber es werden schmalere Säulen, unterschiedliches Trägermaterial und spezielle Reinigungsschritte verwendet; das Verfahren ist anwendbar auf Proben mit einem Gehalt an Plutonium und Uran im Nanogrammbereich und darunter. Die Nachweisgrenzen liegen bei 500 pg Plutonium und 500 pg Uran. In Anhang A ist die Vorbereitung der Säulen und des Säulenträgermaterials beschrieben. Im Gegensatz zu ISO 15366-1 wird aufgrund der geringen Mengen an Uran und Plutonium eine zusätzliche Reinigung auf einem Anionenaustauschharz durchgeführt.
