Inhibiting radiolysis of BTP molecules by addition of nitrobenzene

摘要

Autoradiolysis of extraction systems sometimes occurs during reprocessing of spent fuel, which may result in a change in the extraction behaviour of the system. In the work reported here, an aromatic heterocyclic nitrogen bearing tridentate extraction agent, 2,6-di(5,6-diethyl-1,2,4-triazin-3-yl)pyridine (a BTP), was irradiated using a Co-60 source. The investigation focused on the effect of changing the organic diluent in the extraction system in order to protect the extracting agent from degradation.
