“…Work since these first papers has focused mostly on automation or optimization for a particular sample type, work environment, or regulatory rule changes. [12][13][14][15][16][17][18][19][20][21] Due to this method's importance to safeguards, performance testing has routinely occurred. [22][23] These reports give an overall "state of the practice" for performing this method regardless of what modifications may have been implemented.…”

This report incorporates experimental and modelling data in support of the uranium UV-vis concentration analysis technique as applied to uranium sulfate solutions, and a short literature survey on the 'Industry Standard' Davies-Gray titration method for uranium analysis. A preliminary screen of a suite of contaminants that could interfere with the UV-vis measurement has revealed ruthenium to be by far the most likely to negatively impact the analysis technique, and this element is worthy of a more detailed study. Other experimental work confirm technique reproducibility and solution uniformity over time, and the potential viability of adaption to online analysis, while the application of the Guide to Uncertainty Measurements (GUM) to the UV-vis technique has been explored for the first time. Preliminary modelling analysis using GUM Workbench indicate 0.5 % technique relative uncertainty at the equivalent of two standard deviations, with an associated uncertainty 'budget' which provides guidance as to where the technique can be further developed to lower uncertainties.
