Technology and Components of Accelerator-driven Systems

Introduction

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

Background

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. Followed by 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 will provide experts with a forum to present and discuss state-of-the-art developments in the field of ADS and neutron sources.

Scope

The workshop will cover: 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 to be 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

Programme

The meeting will include special sessions on national ADS programmes and the EURATOM integrated project EUTROTRANS on the first day, together with technical sessions covering all important scientific and technical aspects of R&D activities related to ADS and neutron sources.

	1st day	2nd day	3rd day
Morning session 1	Opening + plenary	Current ADS experiments and test facilities	Neutron sources
Morning session 2	National ADS programmes	Accelerators	Sub-critical systems
Afternoon session 1	EUROTRANS session	Accelerators	Sub-critical systems
Afternoon session 2	Current ADS experiments and test facilities	Neutron sources	Summary session - panel discussion

The proposed topics for the technical sessions are:

1. current ADS experiments and test facilities;
2. accelerators;
3. neutron sources;
4. sub-critical systems.

At the summary session, future needs, controversial results and key experiments will be discussed by experts in the field of ADS.

If necessary, a poster session will be organised on the second day, covering all the technical subjects.
