Nuclear fuel technology — Controlled-potential coulometric measurement of plutonium

This document specifies an analytical method for the electrochemical measurement of pure plutonium nitrate solutions of nuclear grade, with an expanded uncertainty not exceeding ±0,2?% at the confidence level of 0,95 for a single determination (coverage factor, k?=?2). The method is applicable for aqueous solutions containing plutonium at more than 0,5?g/l and test samples containing plutonium between 4?mg and 15?mg. Application of this technique to solutions containing plutonium at less than 0,5?g/l and test samples containing plutonium at less than 4?mg requires experimental demonstration by the user that applicable data quality objectives will be met.
