Workshops

"Decommissioning of Installations and Site Remediation", Arnhem, The Netherlands, October 2003

The 7^th EAN Workshop was devoted to “decommissioning and site remediation”. This was the first time that a workshop re-visited a specific topic: the 1^st EAN Workshop (Saclay, 1997) was devoted to “ALARA and decommissioning”. The main objectives of the workshop were to provide a means of reviewing the recommendations of the first Workshop, progress made in the application of ALARA in decommissioning and the remaining needs both in the nuclear and non-nuclear sectors.

Some 60 participants from 11 European countries attended the Workshop. There were 20 oral presentations, mainly devoted to case studies of work undertaken in a variety of different situations (from accelerators and hot cells, to mineral wool (NORM) facilities and contaminated apartments). In addition to a scene setting session there were sessions on:
