Study on kinetic parameters of pebble bed reactor with TRISO duplex fuel [PDF]
Nuclear Technology and Radiation Protection, 2023 Thorium, in this case, 232Th has a higher thermal neutron capture cross-section than 238U, which means that more fertile isotopes can be transmuted and could lead to higher fissile isotope 233U.
