Preface
Ten papers were presented by invited speakers from overseas and Japan. The foreign invited speakers were from Germany, Italy, Russia, the United Kingdom and the United States. The Japanese speakers were from the Japan Atomic Energy Research Institute, Kyoto University, Nagoya University, Kaken Co., and Toyama University. The meeting was in an appropriate size of about 50 attendants (including ten attendees from overseas), giving a good opportunity to keep close contact for exchanging views and to deepen acquaintance each other.
By focusing attention to the material contamination and the decontamination, up-to-date information were given from both basic and technological viewpoints as kinetics of ad/desorption, trapping/detrapping, diffusion and permeation of hydrogen isotopes on/in metals and non-metals, tritium distributions on/in first walls used in large machines as JET and TFTR, and effectiveness of conventional detritiation techniques and development of new methods.
Each paper commanded strong interest of the attendants and aroused intense discussions. The discussions were liveliest in a very frank atmosphere. The workshop confirmed the importance of further studies on fundamental processes and the development of detritiation techniques. There is a good reason to believe that the tritium management and safety control techniques can be developed extensively through worldwide systematic studies and cooperation.
In closing, thanks should be extended to all of the participants who made the workshop enjoyable and fruitful. Special thanks are due to Drs. Aiello, Bell, Glugla, Livshits and Willms visiting Toyama from overseas for presenting invaluable papers.
