标准摘要
[中文适用范围]： 本文件规定了通过热电离质谱法测定硝酸溶液中核材料的同位素和元素铀和钚浓度的方法。 该方法适用于辐照Magnox和轻水堆燃料（沸水堆或压水堆）、乏燃料后处理厂的最终产品以及MOX和铀燃料的进料和产品中的铀和钚同位素组成和浓度测量制造。 该方法适用于其他燃料，但如有必要，化学分离和加标溶液可适应每种类型的燃料。 [外文原描述]： This document specifies a method for the determination of the isotopic and elemental uranium and plutonium concentrations of nuclear materials in nitric acid solutions by thermal-ionization mass spectrometry. The method applies to uranium and plutonium isotope composition and concentration measurement of irradiated Magnox and light water reactor fuels (boiling water reactor or pressurized water reactor), in final products at spent-fuel reprocessing plants, and in feed and products of MOX and uranium fuel fabrication. The method is applicable to other fuels, but the chemical separation and spike solution are, if necessary, adapted to suit each type of fuel.
