Workshops
Feed back experience shows that there is in Europe a need for Workshops which are neither a big congress nor a collection of working groups with lots of different meetings, but which over a few days provide a forum for a few dozen experts to exchange feedback experience and to identify problems that need further research or development. Therefore the Network has organised and will continue to organise such type of Workshop once a year.
The subject is selected in order to cover domains where the Network Steering Committee Group estimates that many improvements in terms of ALARA implementation may be found. All papers are invited presentations. To promote discussions, appropriate time is made available for work in small groups and the number attending the workshop is limited to a few dozens experts. The language of the Workshops is English.
At the end of each Workshop the chairpersons and the working groups propose to the participants some recommendations to the EC and national regulatory bodies and other stakeholders corresponding to the feedback from the sessions of the Workshop. These recommendations are validated by the Network Steering Committee Group and send to the Commission and to other appropriate stakeholders.

18th European ALARA Network Workshop [organized in collaboration with ISOE], Marcoule, France, 11 – 13 March 2019
"ALARA in Decommissioning and Site Remediation"
____
The participants (ICSM Marcoule, 11th March 2019).
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.
