ASN Report 2018

access to its draft resolution on the EDF action plan concerning the implementation of new containment works on the Civaux site, where the pollution containment strategy was considered to be ineffective. The organisation adopted by the sites to prevent risks resulting from the dispersion of pathogenic micro-organisms by the cooling towers needs to be further improved. The time needed to ensure compliance of the methodical risks assessment document led ASN to serve the Chinon site with formal notice on this point on 14 June 2018. Although ASN has observed progress by some sites that had previously been under-performing on the subject of waste management, it is still waiting for EDF to make significant improvements to the organisation on most sites with regard to this topic. On the whole, discharges are considered to be well-managed on the sites. However, evaluation errors detected by the licensee in 2018, or monitoring equipment unavailability constitute occasional weak points in the control of discharges which need to be remedied.

This for example entails: • keeping the results as-are for the Golfech site, which has two reactors; • dividing by two those of Chinon, which has four reactors (Chinon/2); • dividing by three those of Gravelines, which has six reactors (Gravelines/3). In addition, the discharge data transmitted by EDF to ASN for each site are not representative of the operating time of the installations or of the activities.
