Determination of uranium in reactor fuel solutions and in uranium product solutions — Iron (II) sulfate reduction/potassium dichromate oxidation titrimetric method

Dosage de l'uranium dans les solutions de combustibles pour réacteurs et dans les solutions de produits à base d'uranium — Méthode titrimétrique par réduction par le sulfate de fer (II) et oxydation par le dichromate de potassium

Abstract / scope

Specifies an analytical method for the accurate and precise determination of uranium in solutions of reactor fuels fed to reprocessing plants and in the uranyl(VI) nitrate product solutions from such plants. The method can be used directly for the analysis of nitric acid solution of most uranium and uranium/plutonium oxide reactor fuels, either irradiated or unirradiated. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere.
