Non-proliferating reprocessed nuclear fuels in pressurised water reactors: fuel cycle options

Many alternatives have been studied in the attempt to burn Plutonium produced in the last decades. 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.
