Possible scenarios for the transition to thorium fuel cycle in molten
Conclusions This work focuses on giving a solution to achieve the transition from enriched uranium to thorium fuel cycle in a MSR. With support of an in-house developed computing tool, the B&B scenario and the Pre-breeding scenario are both put forward and discussed. Some parameters, including the nuclides evolution and net 233U production, are ...

Nature, Sources, Resources, and Production of Thorium
Thorium is a naturally occurring, slightly radioactive element. It is widely distributed in nature with an average concentration of 10.5 ppm Th in the upper earth's crust. In general, thorium occurs in relatively small number in Th-enriched minerals: thorite, thorianite, monazite, bastnaesite, and thorogummite. However, the main world resources of thorium are coupled …

Neutronic design performance of 100 MWe MSR with thorium-enriched
Since U-233 is a virtual fissile that must be breeded from the Th fuel cycle on the reactor (C. Zou et al., 2018), the utilization of enriched Uranium becomes an option as MSR starting fuel.Some studies reported that utilizing low-enriched uranium and thorium in the reactor system can reduce plutonium production by about 75% (Bromley et al., 2019).
