Fast Reactors and Accelerator Driven Systems Knowledge Base

This publication represents the meeting report of 1st Research Coordination Meeting (RCM) of IAEA’s Coordinated Research Project (CRP) on " Analytical and Experimental Benchmark Analyses of Accelerator Driven Systems (ADS) "

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 objectives of the 1st RCM of the CRP were to :

• Review the status of analytical and experimental work performed in the participants’ organizations in the field of transmutation R&
• Agree upon the topical areas to be covered by the CRP, including the identification of the experiments to be considered for the experimental benchmark exercises
• Identify lead organisations among the CRP participants for each of the topical areas
• Propose, discuss and agree upon the various analytical and experimental benchmark exercises to be performed within the framework of the CRP
• Produce an agreed upon definition of detailed tasks as well as work plans and deadlines for completing the agreed upon analytical and experimental benchmark exercises
• Identify interest and participants in each benchmark task
• Clarify responsibilities for competing tasks

The meeting discussed 17 different benchmark exercise proposals that had been submitted by the participants. Out of these proposals, the meeting decided to retain (at least for a first stage of the CRP) 7 benchmark exercises.
