Well, yes and no. Basically LWRs are good enough for the time being. When/if there's a major expansion of nuclear power, we'll need breeders and reprocessing, but right now there's no pressing need. Right now what nuclear power needs (from the technical POV) is to reduce the time and cost of construction. Which, most likely, won't happen by introducing new and unproven reactors and fuels.
