Research coordination meeting of the coordinated research project on analytical and experimental benchmark analyses of accelerator driven systems. Working material

The Technical Meeting hosted at the Belarus National Academy of Sciences in Minsk by the Joint Institute of Power Engineering and Nuclear Research 'SOSNY' from 5-9 December 2005 was the kick-off Research Coordination Meeting (RCM) of the IAEA Coordinated Research Project (CRP) on 'Analytical and Experimental Benchmark Analyses of Accelerator Driven Systems (ADS)'. The CRP had received proposals for research agreements and contracts from scientists representing the following 25 institutions: Centro Atomico Bariloche, SCK CEN Mol, Instituto de Pesquisas Energeticas e Nucleares Sao Paulo, Joint Institute of Power Engineering and Nuclear Research SOSNY Minsk, China Institute of Atomic Energy, CEA Cadarache, CNRS Paris, FZ Rossendorf, FZ Karlsruhe, Budapest University of Technology and Economics, Politecnico di Torino, Japan Atomic Energy Agency, Nuclear Research and Consultancy Group (NRG) Petten, Pakistan Institute of Nuclear Science and Technology, AGH-University of Science and Technology Krakow, Institute of Atomic Energy Otwock/Swierk, ITEP Moscow, MEPHI Moscow, Kurchatov Institute, JINR Dubna, Universidad Politecnica de Madrid, CIEMAT Madrid, Royal Institute of Technology Stockholm, National Science Center 'Kharkov Institute and Technology', and Argonne National Laboratory). These institutions represent 18 IAEA Member States (i.e., Argentina, Belarus, Belgium, Brazil, China, France, Germany, Hungary, Italy, Japan, Netherlands, Pakistan, Poland, Russia, Spain, Sweden, Ukraine, USA), and one International Organization (JINR Dubna). The overall objective of the CRP is contributing to the generic R and D efforts in various fields common to innovative fast neutron system development, i.e., heavy liquid metal thermal hydraulics, dedicated transmutation fuels and associated core designs, theoretical nuclear reaction models, measurement and evaluation of nuclear data for transmutation, and development and validation of calculational methods and codes. Ultimately, the CRP's overall objective is to make contributions towards the realization of a transmutation demonstration facility. The specific objective of the CRP is to improve the present understanding of the coupling of the ADS spallation source with the multiplicative sub-critical core. As outcome, the CRP aims at advancing the efforts under way in the Member States towards the proof of practicality for ADS based transmutation by providing an 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 CRP will address all major physics phenomena of the spallation source and its coupling to the sub-critical core. The participants will perform computational and experimental benchmark analyses using integrated calculation schemes and simulation methods. Apart from analytical benchmark exercises, the CRP will integrate some of the planned experimental demonstration projects of the coupling at power between a sub-critical core and a spallation source (e.g., YALINA Booster in Belarus and SAD at JINR, Dubna). The estimated duration of the CRP is 5 years. Following the establishment, during 2004, of the international CRP team by putting in place research agreements and contracts, and after convening this kick-off research RCM, the implementation plan of the CRP foresees three more RCMs (in 2007, 2008, and 2009, respectively), and the publication of the final report in 2010.
