Thorium-based mixed oxide fuel in a pressurized water reactor: A feasibility analysis with MCNP
… Using a three-dimensional MCNP model of a Westinghouse-type 17x17 PWR, several fuel compositions and configurations of a one-third ThMOX core were compared to a 100% UO<sub>2</sub> core. A blanket-type arrangement of 5.5 wt% PuO<sub>2</sub> was determined to be the best candidate for …
