标准摘要
[中文适用范围]: 本文件规定了大型示踪剂(通常称为'大尺寸示踪剂')的制备和验证方法,其不确定性适合于国际核保障用于同位素稀释质谱法测量钚和/或铀的含量。此测量方法学可用于未辐照的镁诺克斯燃料和轻水反应堆燃料(沸水反应堆或加压水反应堆);在spent-fuel再处理厂中的最终产品;混合氧化物钚和铀(MOX)的进料和产物;以及铀燃料制备。 [外文原描述]: This document specifies a method which applies to the preparation and validation of the standard materials generally called “large size spikes” with an uncertainty suitable for international nuclear safeguards used for measuring the content of plutonium and/or uranium by isotope dilution mass spectrometry. This measurement methodology can be applied to input solutions of irradiated Magnox and light water reactor fuels (boiling water reactor or pressurized water reactor); in final products at spent-fuel reprocessing plants; in feed and products of mixed oxide of plutonium and uranium (MOX); and in uranium fuel fabrication.
