Technology and Components of Accelerator-driven Systems

First International Workshop


Karlsruhe, Germany
15-17 March 2010

Presentations (password required)




The OECD Nuclear Energy Agency (NEA) is organising the first international workshop on Technology and Components of Accelerator-driven Systems (TCADS-1). The meeting was held in Karlsruhe, Germany on 15-17 March 2010, hosted by the Karlsruhe Institute of Technology (KIT) and co-sponsored by EUROTRANS.


The accelerator driven system (ADS) is a potential option of a transmutation system in terms of the partitioning and transmutation strategies for the radioactive waste in the advanced nuclear fuel cycle. Following the success of the workshop series on the utilisation and reliability of high power proton accelerators (HPPAs), the scope of the new workshop series has been extended to cover sub-critical systems as well as the use of neutron sources. This workshop provides experts with a forum to present and discuss state-of-the-art developments in the field of ADS and neutron sources.


The workshop covers: R&D status on ADS including accelerators, neutron sources and sub-critical systems for current facilities and future experimental and power systems; technology, engineering and research aspects of the above components; system optimisation for reducing capital and operational costs; and the role of ADS in advanced fuel cycles.

Proposed topics and subjects discussed are:

  • Specific aspects of ADS accelerators
    • Continuous mode and operational control
    • Reliabilities and fail safety
    • High beam power and low losses
    • Safety systems
  • Neutron sources
    • Current and future intense neutron sources
    • Spallation and non-spallation targets
    • Design concepts and required technologies (e.g. coolant, materials, performance, instrumentation, etc.)
    • Operational characteristics and related technical issues (e.g. window/windowless, solid/liquid, interface between accelerator and target, etc.)
  • Sub-critical systems
    • Design concepts and performance parameters (e.g. transmutation, energy production, etc.)
    • ADS fuel/target design options
    • Sub-critical reactor physics (e.g. reactivity monitoring, etc.)
    • Materials, coolant technology and thermal-hydraulics
    • Unique ADS auxiliary systems (e.g. target replacement, refuelling machine, etc.)
    • Related safety issues
  • Current ADS experiments and test facilities
    • Low power coupling experiments
    • Zero power physics simulators
