How to generate energy from nuclear waste

The medieval alchemists sought to transmute lead into gold. Today, inside nuclear reactors something similar happens: uranium bombarded with neutrons becomes other lighter elements such as technetium.

The problem is that these wastes are radioactive for thousands or millions of years.
What to do with them? One possibility is used as fuel for another type of reactor, called subcritical because the nuclear reaction is not maintained by itself, as in conventional power plants. The new, the neutrons provides a particle accelerator added to the reactor.

This is achieved by reducing the mass of waste and radioactive shorten their lives just a few hundred years.
Kyoto University has set up the laboratory KART, which will study the feasibility of this idea, whose creator was Cario Rubbia, Nobel Physics and former director of the Research Center for Particle Physics CERN in Switzerland.
It is the third time that seeks to promote this project was tried in 2004 in Italy and in 1997 at Aragon. On both occasions was canceled for political reasons: it does not sell nuclear.
