Energy: towards nuclear breeder installations before the end of this century?

To play an essential role in the energy crisis, the civilian nuclear fission industry urgently requires a large and safe underground deposit for irradiated materials. Breeder reactors should be required to extract more energy, not to eventually reduce the radioactivity of dangerous materials. These two aims still require much work, from the fundamental issue of the mechanics of materials, to large industrial parks for breeder development on an international basis.
