This is due to the different type of potential energy surface between the two fissioning systems.
Web7 Dec 2024 · The total mass of thorium recovered was 91.32 ± 0.77 mg: 83.67 ± 0.76 mg of 232 Th and 7.65 ± 0.10 mg of 230 Th. The amount of 230 Th present in the ore initially can be calculated from the mass of uranium and 235 U/ 238 U ratio; this gives a result of 10.8 ± 0.8 mg 230 Th, indicating an overall yield of 71.1 ± 5.4% for thorium recovery.
