 Design Parameters

Conceptual design of an Accelerator Driven System
(ADS) for energy production in subcritical reactor as
well as for transmutation of nuclear waste.

To achieve this goal we propose a CW proton facility
capable to feed the reactor with 30 MW proton beam
at 1 GeV.

              •   Power the accelerator with “clean”
                  energy
              •   Transmutate French nuclear waste
              •   Return power to the grid
