Under the auspices of the IAEA, nationally developed Underground Research Facilities (URFs) and associated laboratories are being offered for use by other nations. The URFs and laboratories form a “Network of Centres of Excellence” for training in and development of waste disposal technologies. If your organisation is from a participating country in the IAEA training network scheme you may be able to request financial support from the IAEA for courses run as part of the Network scheme.

An international conference and workshop in the framework of the European Commission TIMODAZ and THERESA projects to be held from 29 September to 1 October 2009, in Luxembourg.
Jointly organised by the European Commission and EIG EURIDICE (Belgium), KTH (Sweden), ITC (Switzerland)
Sponsored / supported by Hosted by the European Commission The disposal of radioactive waste in deep geological formations has been a subject of intensive research activities in the last decades. Three main host rock formations are generally found to be the most suitable formations for deep geological disposal of these wastes: crystalline rocks, clay formations and salt. In all these formations, an important item for the long-term safety of underground disposal is the assessment of the combined effect of excavation, buffer emplacement and thermal output on the host rocks around the repository. More specifically, the extent of the associated damaged or disturbed zone (DZ/dZ) and their evolution with time are the focus of intensive research. The early THMC disturbances (thermal-hydrological-mechanical-chemical) created by the excavation, the operational phase and the thermal load might be the most severe transient processes that a repository will undergo on a large spatial scale. This is why experimental (laboratory and in-situ in Underground Research Laboratories) and numerical studies are on-going around the world to better understand the coupled THMC processes in the context of the long-term evolution and safety of repositories. In November 2003, a European Commission CLUSTER Conference and Workshop on "Impact of the excavation disturbed or damaged zone (EDZ) on the performance of radioactive waste geological repositories" was successfully held and reflected well the state of the art of the EDZ at that time. The coming conference/workshop intends to go one step further from this EDZ CLUSTER conference by specifically addressing the DZ and buffer evolutions with time and temperature. The objectives for the conference and workshop are to update, synthesize and work towards a consensus on:
Main Topics Present understanding of the nature, properties & evolution of the damaged zone
Present understanding of the THMC processes in host rocks
THMC behaviour at the interfaces host rocks – seal / buffer
Performance assessment & modelling
Significance and integration in Safety Case?
Structure of the conference (29.9.09) and workshop (30.9.09 - 1.10.09) The whole event will last 2½ days and will consist of:
followed by a 1½ days of workshop (upon invitation only) which will consist of:
Workshop Participation in the workshop will be open to individuals and organisations involved in the workshop specific topics (upon invitation only). Three working groups will be set-up based on the different host rocks: one for Crystalline rocks & Buffer (Chairman : A. Gens), one for Clays (Chairman : F. Bernier) and one for Salt (Chairman : T. Rothfuchs). The following topics will be discussed:
As a guideline for the discussions, the following questions will be addressed in the working groups:
Participation to the workshop will be limited to enhance discussion. Each working group will be chaired by a representative of the Organization Committee, who will be assisted by a rapporteur in charge of preparing the working group summary and to produce a written contribution for the proceedings. Closure of workshop on 1st October at around 12:30. Preliminary Conference Programme
Official Language All oral and written communications of the conference and workshop will be in English. Publication Available for download : Book of abstracts - PDF 2.6 MB The final proceedings will be published and distributed by EC after the Conference and Workshop. They will include a synopsis of the conference, a workshop summary, working group discussion summaries, the peer reviewed papers of the invited lectures (15 pages including figures), the extended abstracts for the oral presentations (10 pages maximum including figures) and for the posters (5 pages including figures).
