ASN notes that difficulties with industrial radiography work observed in 2022 are persisting, in the light of the number of significant events notified with respect to these worksites, despite the action taken by EDF in this field. The inspections were also able to identify points on which improvements are required in controlling the risk of the dispersal of contamination within and outside the installations, in particular in the “auxiliary” premises (such as waste conditioning buildings, units dedicated to contaminated equipment or buildings for final inspection of packages prior to shipment). During the inspections scheduled in 2024, notably as part of a new campaign of tightened inspections, ASN will be particularly vigilant with respect to all of these points. 2.8 LABOUR LAW IN THE NUCLEAR POWER PLANTS 2.8.1 Oversight of work in the Nuclear Power Plants ASN is responsible for labour inspectorate duties in the 18 NPPs, the EPR reactor under construction at Flamanville and 11 other installations, most of which are reactors undergoing decommissioning. 800 to 2,000 people work in each NPP. About 23,000 EDF employees and 11,000 employees from outside contractors are thus assigned to these nuclear sites. The role of the labour inspectorate is to ensure that the Labour Code as a whole is applied by the employers, whether EDF or its contractors.
