High performance liquid chromatographic separation of 228,229Th and 232,233U and their estimation by α- and γ-ray spectrometry

Abstract

The activities of 228,229Th and 232,233U from an irradiated ThO2 sample were radiochemicaly separated by using high performance liquid chromatography. Plancheted sources of the separated samples were made and the amount of 232,233U and 228,229Th were estimated by using alpha and gamma-ray spectrometric techniques. These estimations are important for the Th–U fuel reprocessing cycle of advanced heavy water reactor and accelerator driven sub-critical system.
