ISO 9463:2019 Nuclear energy - Nuclear fuel technology - Determination of plutonium in nitric acid solutions by spectrophotometry
standard by International Organization for Standardization, 02/01/2019
Full Description
This document specifies an analytical method by spectrophotometry, for determining the plutonium concentration in nitric acid solutions, with spectrophotometer implemented in hot cell and glove box allowing the analysis of high activity solutions. Commonly, the method is applicable, without interference, even in the presence of numerous cations, for a plutonium concentration higher than 0,5 mgl1 in the original sample with a standard uncertainty, with coverage factor k = 1, less than 5 %.
The method is intended for process controls at the different steps of the process in a nuclear fuel reprocessing plant or in other nuclear facilities.
