Radioactive Waste Management and Disposal 1985

R. Simon

The European Community's research programme 'Management and Disposal of Radioactive Waste' has the prime objective of finding effective means for ensuring the safety of man and his environment against the potential hazards arising from such wastes. In 1980, the Commission of the European Communities held its first major meeting on the subject, and published the proceedings, discussions and results. This volume presents the proceedings of the second such conference, following the completion of a research and development programme in the five intervening years. The main topics discussed are: treatment and conditioning technology, testing and evaluation of waste forms and packages, geologic disposal, migration, and performance analysis of geologic isolation systems; representing an analysis of the latest results achieved by sustained collaboration of leading laboratories in Europe. Thus, all of the contributions are of a high standard from the major exponents in the field throughout the European Community.
