Abstract

Near term deployment of fast reactors in the US is inhibited, in part, by the unavailability of plutonium recovered from reprocessing of discharged light-water- reactor (LWR) fuel. There is, however, a way to make a once-through U-235 fueled sodium-cooled fast reactor (SFR) core economically competitive with its LWR counterpart. A principal enabling factor is the use of high- albedo MgO reflectors in lieu of depleted uranium radial and axial blankets (1) (2). The resulting core is then usually limited by cladding fluence rather than reactivity lifetime, leading to a tradeoff between reducing U-235 enrichment to reduce fuel cost versus increasing it to reduce flux, hence fluence. A compromise design is described which has projected once-through fuel cycle costs, in mills/kWhre, comparable to that of current LWRs.
