Outline Goal Existing Facilities Solution Overview Components Reliability Location Summary

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.
