标准摘要
[中文适用范围]： 本文件规定了一种通过 X 射线荧光光谱法测定 UO2 燃料芯块中 Gd2O3 含量的方法。波色散 X 射线荧光 (WD-XRF) 或能量色散 X 射线荧光 (ED-XRF) 均适用，但本文件规定了一种使用 Gd Lα 线的 WD-XRF 方法。该方法已针对 2% 至 10% Gd2O3 的质量分数进行了测试。 [外文原描述]： This document specifies a method which covers the determination of Gd 2 O 3 content in UO 2 fuel pellets, by X-ray fluorescence spectrometry. Either wave dispersion X-ray fluorescence (WD-XRF) or energy dispersion X-ray fluorescence (ED-XRF) is applicable, however, this document states a method by using WD-XRF using Gd L α -line. This method has been tested for mass fractions of from 2 % to 10 % Gd 2 O 3 .
