Nuclear energy - Determination of Gd2O3 content in gadolinium fuel blends and gadolinium fuel pellets by atomic emission spectrometry using an inductively coupled plasma source (ICP-AES) (ISO 16796:2022)

Scope

This document is applicable to the determination of gadolinium as Gd2O3 in powder blends and sintered
pellets of Gd2O3 + UO2 and ((U, Gd) O2) 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
