“…In particular, high-temperature gascooled reactors (HTGR) are being studied as they constitute interesting innovative GEN-IV concepts (Cerullo and Lomonaco, 2012) for advanced Pu/Th cycles (Mazzini et al, 2008), which may target waste reduction (Cerullo et al, 2015;Bomboni et al, 2008). Thorium resources are indeed abundant enough for a long-term and sustainable development of thorium-based cycles (Warren and De Simone, 2014). In the gap (2030-2050), thorium may be used to save uranium resources, improve spent fuel management and/or plutonium recyclability (Energy Policy Editorial, 2014).…”

Thorium constitutes a natural resource alternative to uranium to fuel nuclear fission power plants. This study explores an original way to benefit from thorium with pressurized water reactors (PWR). It relies on a versatile reactor EPR™ core concept which well circumscribes thorium fuel reprocessing and re-fabrication Fleets representative of what can be deployed at the scale of a small country were simulated using the scenario software COSI6. The cornerstone of this study is here the possibility to multi-recycle plutonium into Pu/Th fuel as plutonium degradation is softened by mixing it with high-grade fissile matters. Plutonium content inside Pu/Th fuel remains then far below the limit existing in PWR for safety reasons. This synergistic effect between U/Pu and U/Th cycles enables a better valorization of fissile elements present in spent fuels. Improved plutonium management makes possible to stabilize spent fuel stocks and the plutonium inventory at the cycle back-end. Thanks to multi-recycling allowed by the U/Pu/Th studied scheme, uranium resource savings exceed 25%. Minor actinides production is also reduced even though production of curium alone increases. These results reveal that thorium introduction in standard PWR may be a sustainable middle-term option, assuming that U/Pu/Th fuel reprocessing and re-fabrication would become available.
