Held: 5th - 7th May, 2004 - Meiringen, Switzerland: Workshop on Case Studies of Subsurface Radionuclide Migration. (Full details:  PDF file 904 kb )
Objectives
Understanding the physical and chemical controls on radionuclide mobility in rocks, soils and groundwaters is central to evaluating and remediating contaminated nuclear and other industrial sites. It is also important in developing and assessing the future performance of radioactive waste disposal facilities. This workshop focuses on what can be learned from real case studies of contaminated sites and is intended as a forum to bring together those working in this field to share their findings.
Key case studies will be recent work on Chernobyl in the Ukraine and sites in Russia, where the final results of work carried out in the SCOPES 2000 joint Russian - Ukrainian - Swiss National Science Foundation research project will be reported.
The workshop will provide an opportunity to link Eastern and Western European research activities. An associated visit to the Nagra underground rock laboratory at Grimsel will provide an opportunity to see in situ experimental work on radionuclide movement in fractured rocks.

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.
