核能.使用电感耦合等离子体源（ICP-AES）用原子发射光谱法测定钆燃料混合物和钆燃料芯块中的Gd2O3含量

[中文适用范围]： 本文件适用于质量分数 10 g/kg 至 100 g/kg（即 1 % 至 10 %）的 Gd2O3 + UO2 和 ((U, Gd) O2) 的粉末混合物和烧结球团中以 Gd2O3 形式测定钆。 ，使用合适的 ICP-AES 仪器。 该方法能够证明符合商定的燃料规格和相关的数据质量目标，前提是用户在其既定的测量控制程序下执行了资格测量，以证明测量不确定性要求将满足规范中所需的置信水平。 [外文原描述]： This document is applicable to the determination of gadolinium as Gd 2 O 3 in powder blends and sintered pellets of Gd 2 O 3 + UO 2 and ((U, Gd) O 2 ) from mass fraction 10 g/kg to 100 g/kg (i.e. 1 % to 10 %), using a suitable ICP-AES instrument. This methodology is capable of demonstrating compliance with agreed upon fuel specifications and associated data quality objectives provided the user has performed qualification measurements under their established measurement control program to demonstrate that measurement uncertainty requirements will be met with the desired level of confidence at the specification.
