The overall objective of the Fifth Worldwide Review (WWR-5) Workshop is to summarize the experience and lessons learned documented in the Fifth Worldwide Review Report, and to establish future cooperation/collaboration between the participating countries pursuing geological disposal programs.

The Workshop will include oral presentations of the countries, followed by group discussions of the materials. The materials of the group discussions will be summarized as individual chapters and included in the final edition of the Fifth Worldwide Review report, which will be issued after the workshop (see all Worldwide Review reports). The Fifth Worldwide Review report will be published as an e-book, and the Oxford Research Encyclopedia (ORE) will publish an article-summary of the report which will feature links to individual chapters of the report.

In particular, the presentations will include the following types of information: the current status of the deep geological repository programs for high nuclear waste and low- and intermediate nuclear waste and in each of the countries, concepts of siting and radioactive waste and spent nuclear fuel management in different countries (with the emphasis of nuclear waste disposal under different climatic conditions and different geological formations), progress in repository site selection and site characterization, technology development, buffer/backfill materials studies and testing, support activities, programs, and projects, international cooperation, and future plans, as well as regulatory issues and transboundary problems.
