Nitride Fueled Accelerator-Driven System with High Source Efficiency

摘要

Accelerator-driven systems (ADS) were proposed[1] and widely investigated for multi-recycling of americium, curium, and plutonium[2-5].rnIn the frame of the EUROTRANS project[6] two composite oxide fuel options for the European Facility for Industrial Transmutation (EFIT) were investigated - with a MgO matrix (ceramic-ceramic, cercer)[7], and with molybdenum matrix (ceramic-metallic, cermet)[8]. Both fuel options have their advantages; however, they both show significantly lower neutron source efficiency compared to the demonstration facility of XT-ADS[9] loaded with MOX fuel. This results in a much higher accelerator current requirement and thereby higher radiation damage in the target area.
