|A large reduction in the radioactive toxicity of waste...|
The reduction in toxicity obtained by transmuting all the minor actinides into fission products is enormous (green area). The actinides are transmuted into much more short-lived fission products (curve C). The curve is obtained by dividing the contribution of the fission products to the spent fuel of a PWR reactor (curve A) by the ratio of the fissile masses: 35 kg per tonne of uranium on the one hand and 800 g of actinides to undergo fission on the other. In principle this reduction is of several orders of magnitude.
