There are a number of challenges and uncertainties in the field of occupational radiation protection (ORP) during the decommissioning of nuclear power plants The aim of the WGDECOM is to identify and create a network of radiation protection (RP) experts to discuss RP and related issues relevant to decommissioning.  The WGDECOM focuses on practical case studies and expert discussions with NPPs undergoing decommissioning to help identify good practices in the field of ORP during decommissioning. Ideally, this work will help to collect and disseminate operational experiences and lessons learned for NPP decommissioning.
