TRADE: A full experimental validation of the ADS concept in a European perspective

The three levels involved in the experimental validation of an Accelerator Driven System (ADS) are discussed. TRADE is referenced as the most important step toward the ADS demonstration. The types of measurements required to perform in TRADE are also discussed. The TRADE experiments are preferred as they have the ability of incorporating the feedback effects into the dynamics measurements in ADS and to address ADS operational, safety and licensing issues. The categories of the types of experiments performed are: start-up and shut down procedures, operation and monitoring of the system at steady state, monitoring of the time evolution of the reactivity, and practical coupling of an accelerator, a spallation target and the subcritical core.
