15 YEARS OF RESEARCH-AND-DEVELOPMENT ON DIRECT DISPOSAL IN GERMANY - AN OVERVIEW

Studies on direct disposal of spent fuel started in Germany in 1979. F rom 1985 to 1995, a research and development (R&D) project was conduct ed, the objective of which was to develop direct disposal to technical maturity. The main results of this project are presented. As a conseq uence of this R&D effort, the German Atomic Energy Act was amended in 1994, eliminating the priority of reprocessing and recycling over dire ct disposal. The judgment of direct disposal by politicians and the nu clear community was subject to change during the period from 1980 thro ugh 1995. While initially technical feasibility was the dominating iss ue, the picture changed after the Act had been amended. Evidence of gu aranteed Entsorgung, meaning all steps at the back end of the fuel cyc le and which is provided by foreign reprocessing contracts, turned out to be an important decision criterion.
