Among these, there are the reprocessing of the Plutonium and the insertion of Thorium in thermal reactors. Nevertheless, the proliferation risk is always associated with conventional reprocessing techniques, such as PUREX. Hence, alternative reprocessing methods with low-grade decontamination and uraniumplutonium co-extraction characteristics have been proposed. Besides that, the insertion of Thorium in fuels coming from PUREX has shown good results. Therefore, based in these data, fuels coming from alternative techniques of reprocessing such as Coprocessing and AIROX, have been analysed, with and without the insertion of Thorium. The goal is study fuel options with good neutronic and environmental performance.

This depends on the composition of the fuel and on the irradiation conditions. Previously the insertion in PWR of fuels coming from alternative reprocessing techniques has been proposed and many studies have been developed to evaluate their neutronic viability. This article tries to analyse the waste generated by these fuels when submitted to the same irradiation conditions. To reprocess the fuels alternative techniques were used. Coprocessing and AIROX Multirecycles will be simulated and the eects of the insertion of Thorium in the composition of these reprocessed fuels will be studied. In comparison the standard fuel used UO 2 was also simulated. The goal of this study is to verify the radiological risk associated with the simulated fuels relating the fuel inventory to its radiotoxicity.
