Technology Advances in Fast Reactors and Accelerator Driven Systems

Several countries with nuclear programs are considering ADS systems as a method to implement nuclear waste transmutation in the scope of their nuclear waste management strategies. The proposed CRP will advance the MS efforts towards designing a demonstration facility by providing the information exchange and collaborative research framework needed to ensure that the tools to perform detailed ADS calculations, namely from the high energy proton beam down to thermal neutron energies, are available. The specific objective of the proposed CRP is to improve the present understanding of the coupling of ADS spallation sources with multiplicative sub-critical nuclear systems. In the previous IAEA-CRP on "Use of Th-based Fuel Cycle in ADS to Incinerate Pu and to Reduce Long-lived Waste Toxicities" reactor physics benchmark calculations on ADS with fixed external neutron sources have been performed. Comparison of the results of this CRP shows that large discrepancies exist both related to the use of different methods and data. By including comparisons with integral experiments, the proposed CRP will contribute to the clarification of these discrepancies and validate also those results for which satisfactory agreement was reached in the previous CRP. The proposed CRP will address all major physics phenomena of the spallation source and its coupling to the sub-critical system. Integrated calculation schemes will be used by the participants to perform computational and experimental benchmark analyses.
