Hybrid reactor demonstration facility
Reactors coupled with an accelerator could be used solely and specifically for incinerating radioactive waste. These hybrid systems combine a high-intensity proton accelerator (not shown in the figure), from which the protons enter the top left part of the reactor and generate fast neutrons, with a 'subcritical' fast neutron reactor. The possible use of these Accelerator Driven Systems or ADSs is still a long way off. The first demonstration facilities or prototypes such as the European MYRRHA project are envisaged for the middle of the next decade at the earliest
