OBJECTIVES AND CURRENT STATUS OF THE IAEA NETWORK OF CENTERS OFEXCELLENCE: TRAINING IN AND DEMONSTRATION OF WASTE DISPOSALTECHNOLOGIES IN UNDERGROUND RESEARCH LABORATORIES

摘要

Underground Research Laboratories (URLs) to develop and demonstrate technologies for the safegeologic disposal of radioactive wastes have been established for national purposes by severalMember States of the International Atomic Energy Agency (IAEA). Under the auspices of the IAEA,nationally developed URLs and associated research institutions are being offered for use by othernations. These facilities form a Network of Centers of Excellence for training in and development ofwaste disposal technologies. Experience gained in the operation of the facilities, and throughassociated experimentation and demonstrations, will be transferred to participating Member Statesthrough hands-on work at the facilities.The Network consists of Network Members and Network Participants who share co-operativeactivities. Network Members are owners of facilities who have offered them to be part of theNetwork. At this time there are eight Members consisting of six underground facilities, a laboratory,and a university. Network Participants can potentially come from any interested IAEA Member Statehaving spent nuclear fuel for disposal, with or without an established program for geologic disposal.There are presently about 15 Network Participants.A significant Network activity beginning in 2003 will be a Coordinated Research Project (CRP) oncharacterization and evaluation of swelling clays for use in engineered barrier systems of geologicrepositories. At the end of this project, every involved Member State should be able to identify andcharacterize a swelling clay that is suitable for use in a geologic repository. As the Network grows,additional CRPs to be carried out in the Underground Research Facilities of the Network Memberswill be defined.
