This document describes an analytical method for the electrochemical assay of pure plutonium nitrate
solutions of nuclear grade, with a total uncertainty not exceeding ±0,2 % at the confidence level of
0,95 for a single determination (coverage factor, K = 2). The method is suitable for aqueous solutions
containing more than 0,5 g/L plutonium and test samples containing between 4 mg and 15 mg of
plutonium. Application of this technique to solutions containing less than 0,5 g/L and test samples
containing less than 4 mg of plutonium requires experimental demonstration by the user that applicable
data quality objectives will be met.
For some applications, purification of test samples by anion exchange is required before measurement to
remove interfering substances when present in significant amounts. Refer to Clause 10 for a discussion
of interferences and corrective actions. Purification is also appropriate in situations where the purity
of the test sample is unknown or when it may fluctuate unpredictably in a manufacturing process.
Clause 11 discusses the changes in application of the method and methodology that can be applied and
important considerations when selecting measurement parameters, while still remaining within the
intended scope of this document.
