Aims and objectives
The objectives of the workshop were:
- To present the regulatory background and latest guidance and
- standards regarding radiation protection for decommissioning and site remediation; both in the nuclear and the non-nuclear sectors.
- To examine the conceptual and the practical aspects of the optimisation (ALARA) principle in these fields for workers and the public. The workshop aims at gathering a large array of experience and feedback from work performed in nuclear installations, installations outside the nuclear fuel cycle (ex. research facilities) and legacy sites.
- To discuss and investigate selected key themes and overriding issues with regard to ALARA; to identify remaining needs and perspectives.
The workshop was jointly organized with the ISOE Working Group on Decommissioning (WG-DECOM).
Programme
The final programme is available here. As part of the programme, time was devoted for discussions in working groups between participants. A technical visit of Marcoule installations was organized.
