This presentation will discuss the Fast Chloride-Molten Salt Reactor (FC-MSR) at a high level to support fuel cycle discussions. The presentation will discuss different processes for the FC-MSR for: FC-MSR Front End from LWR Backend of the fuel cycle A) Converting SNF to Start Up Fuel for a FC-MSE, 1) (prefered) as a method of denaturing weapons grade Plutonium as the primary fissile, 2) as a method of consuming separated reactor grade Plutonium fissile, 3) fissile from SNF without Plutonium separations, 4) SNF Zirconium clad recycling, 5) fissile from HALEU Main Lifetime Fuel Cycle 3kg/day of SNF B) Converting SNF to Feed-In Fuel for the all fuel additions following Start Up without added fissile. C) FC-MSR on-line Purification Purification & Waste D) 40-60yr periodic purification to remove excess fission products, actinide & chloride recycling E) Options for FC-MSR waste product stabiliztion & disposition Conclusions/Opportunies relative to DGRs
