Nosaukums<p class="MsoBodyText"><span lang="EN-GB">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 <em style="mso-bidi-font-style: normal;">k</em> = 1 of about 5 %, 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 sample from the process containing a concentration of neptunium between 10 mg·l<sup>-1</sup> and 400 mg·l<sup>-1</sup> and uranium concentrations of up to 300 g·l<sup>-1</sup>.</span></p>
