Abstract :
The ®nal disposal of the spent fuel implies an associated environmental impact. 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 gener-
ated 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 UO2 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.
