2.7.2 Assessment of worker radiation protection ASN monitors compliance with the regulations relative to the protection of workers liable to be exposed to ionising radiation in NPPs. In this respect, ASN is attentive to all the workers on the sites, both EDF personnel and those of contractors. This monitoring is performed on each NPP during inspections, either on the specific topic of radiation protection, or during maintenance operations carried out during reactor outages, or as a result of specific events. This monitoring is also carried out during examination of the worker radiation protection files (significant event reports, design, maintenance or modification files, documents implementing the regulations produced by EDF, etc.). During inspections carried out in 2023, in particular during tightened inspections performed on the Tricastin, Cruas-Meysse and Bugey NPPs, ASN found that the operation of the radiation protection competence centres approved at the end of 2022 on all the NPPs, was on the whole satisfactory. The approach used in preparing for work and optimising doses is also considered to be satisfactory on most of the NPPs. Nonetheless, on several NPPs, ASN observed deviations concerning compliance with the particular prevention rules for risks of exposure to ionising radiation applicable to the most vulnerable workers (young workers aged under 18, personnel on short-term contracts) and will be vigilant with regard to how they are dealt with.
