Held : Las Vegas 4th-8th May 2006
Venue : MGM Grand Hotel, Las Vegas, Nevada USA
Course Programme:  pdf file 112 kb
Course outline
This course covers international experience in key aspects of deep geologic disposal of spent fuel and high level radioactive waste that are needed to form the components of a national program, with a special emphasis on the current US HLW program.
The course program (attached) is designed so that the participants can reconfirm and update their present knowledge - from evaluating the wastes to be disposed of, right through all the technical stages of identifying and implementing geological disposal, to the societal interactions required of repository development projects.
The course is considered ideal for professionals working in the implementation, regulation or technical support areas at every stage in their national programs. It will be particularly valuable for those who may just be starting their management-level career on geological disposal projects who need to see geological disposal in its widest context.
The programme consists of 4 to 6 lectures per day in an informal classroom atmosphere with sufficient time allocated for participants to raise questions and answers. Participants will be encouraged to introduce the relevant issues from their own national program and discuss the issues with the tutors and the other participants from around the world.
The course will spend the last day at the Yucca Mountain (planned repository) Site to learn directly about the site investigations to demonstrate the feasibility and safety of geological disposal.
Course organisers
The course is organized by the ITC School of Underground Waste Storage and Disposal with the support of the United States Department of Energy (USDOE, one of the Member organisations of ITC).

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.
