REPORT


Scientific Basis for Nuclear Waste Management XII Held in Berlin 20 Countries Represented The 12th International Materials Research Society symposium on the Scientific Basis for Nuclear Waste Management was held in Berlin, October 10-13, 1988. The meeting was cosponsored with the Hahn-Meitner Institute in Berlin with financial support from the Commission of the European Communities, the U.S. Department of Energy, and private companies in Germany. This was the third time the meeting has been held in Europe (Berlin in 1982 and Stockholm in 1985) as part of a three-year cycle in which the symposium rotates from the MRS Fall Meeting in Boston. In 1991, the meeting will be hosted by the French Commissariat A L'Energie Atomique and sponsored by the European Materials Research Society in Strasbourg. This symposium has become a fine example of international cooperation in organizing international meetings on materials research topics. The meeting was a success by any standard and received prominent coverage in German newspapers. There were over 250 participants from 20 countries. The largest contingents came from the Federal Republic of Germany, United States, France, United Kingdom, Sweden, and Canada. Nearly 190 abstracts were submitted, of which 146 were included in the final program, as well as four invited presentations. The meeting was organized so that there were never conflicting sessions. This was done by having nearly equal numbers of oral and poster presentations. The poster sessions were very effective because they were organized around specific themes. The viewing audience was treated to wine, beer and food; and the poster session chairs assumed the responsibility of organizing discussions around the poster presentations. The audience traveled in small groups from poster to poster—and the discussion was excellent and stimulating. It was great fun to finally have the people who do performance assessments talk to those who generate the laboratory and natural analogue data that go into the performance assessments. One cannot overemphasize the importance of having these diverse groups stand in the same place and explain their work—and its relevance to the problem of the final, safe disposal of nuclear waste. The invited presentations were provocative and enjoyable. Charles McCombie (NAGRA, Switzerland) opened the meeting with "Research Priority: Are We Tack-
