Research on Fuel Cycle of Thorium Advanced CANDU Reactor

The fuel cycle model is one of the most important problem in the concept design of Thorium Advanced CANDU Reactor（TACR）. (Th-U)O₂ CANFLEX fuel bundle, with ThO₂ elements in the inner two rings and slightly enriched uranium（SEU）elements in the outer two rings, was used in the design of TACR. According to the research on the lattice physics of this fuel bundle, a feasible direct self-recycle method was researched for this Th-U fuel bundle.
