Why dont USA shut down the gasseous diffusion plants and replace them with gas centrifuge plants that need an order of magnitude less energy? > What I meant here is that the ratio of power produced to power > consumed in a once-through fuel cycle is much smaller than the ratio > of power produced to power consumed in a fuel cycle with > reprocessing or breeding.

I dont think the difference is significant, if it were the fuel cost would already be hurting the nuclear industry. > Just exactly what the ratio is in any case I don’t know, although I > do recall from reading a quote from Jay Hanson’s reference to > "Gever, et al" that it is greater than unity, hence a net energy > producer, even in the case of a once-through fuel cycle.
