Nuclear energy - Nuclear fuel technology - Determination of neptunium in nitric acid solutions by spectrophotometry
This document specifies an analytical method for determining the neptunium concentration by spectrophotometry, with spectrophotometer implemented in hot cell or glove box allowing the analysis of high activity solutions, with a standard uncertainty, with coverage factor k = 1 of about 5ย %.
The analysis is performed in nitric acid solutions after the dissolution of nuclear reactor irradiated fuels, at different steps of the process in a nuclear fuel reprocessing plant or in other nuclear facilities.
The method is applicable to samples from the process containing a concentration of neptunium between 10 mgยทl-1 and 400 mgยทl-1 and uranium concentrations of up to 300 gยทl-1.
