Participants Kick-off Meeting GTS Phase VI - May 2003


GTS - Future needs

Move from R&D to a programmedriven by planning / implementation of a repository

Raise confidence/acceptance in the key concepts priorto the licensing/construction by full scale engineering projects

Apply state of the art science to confirm key modelsby longer term radionuclide retardation projects; remove conservatism in the modelling approach

Further develop and maintain know-how for key issues like e.g.: handling, emplacement, monitoringretrieval for HLW and SF

Training and knowledge preservation

Grimsel Test Site Phase VI - Concept


After 20 years of operation, ,,Easy R&D‘ has been done (repeatedly); the challenge is to focus more on the needs of the end users (top-down) rather than the interests of researchers (bottom-up)Identified projects are characterized by:

Technical complexity (multi-disciplinary)

Long timescales

Large physical dimensions

Implementation requires

International teams

Phased programmes with clear interim goals (go/no-go decisions)

(Large budgets)

Grimsel Teste Site Phase VI - Aims


Support of repository licensing (construction, operation, closure / decommissioning)

Concept demonstration

Model / database validation

Optimization of repository design, operation, monitoring, closure

Practicality

Safety

QA

Cost

Confidence building (general public & technical stakeholders)

Maintaining state-of-the-art experience in future generations

Grimsel Test Site Phase VI – Key areas & Projects


Engineered Barrier Systems (Long-term behaviour)

Gas migration through the EBS

Long term evolution of the EBS

Near field Processes

Long-term Material Tests

Engineering & operational aspects of repository implementation

Further development of emplacement technologies

Putting UndergroundWork into Practice

5-dayGrimsel, CHMol, Belgium3-7 Nov. 2003


ITC / Grimsel - Resources /1

‘Infrastructure’a long-term perspective to work in / with an URL with an active programmeGTS tunnel sections (TBM drilled, caverns), boreholes, offices &communication tools on-site

‘Networks’benefit from experience gained in crystalline, fractured sedimentary rocks & claykey contractors and institutesfield work, modelling, engineering, technical on-site assistance


ITC / Grimsel - Resources /2

‘Data bases’geological/structural, hydrogeological, geochemical, geophysical, RN-migration data basecharacterised experimental sites & related laboratory programmes access to experimental results, laboratory work (NTB-series)

‘Developed Technology’drilling/sampling, on-site analysis, monitoring systems, special (tracer) test equipment


Outlook Nagra / ITC

ITC / Nagra will further support training courses within the IAEA network Recommendations by the participants / members will help to improve the course structure & contentBeside fundamental courses specialised courses will be organised by the ITC in cooperation with IAEA and Nagra and other member organisations (cf. programme 2005 & 2006)Practical training (in-situ & and class room lessons) will be a focus
