ASN Report 2020

of pollution, which are the responsibility of the licensee, are regulated by ASN resolution 2013-DC-0360 of 16 July 2013 and the Order of 7 February 2012 and must also comply with the requirements of the European texts. The licensee has obligations regarding the operational management of these substances and the identification of the corresponding potential hazards. It must also be able to take the necessary steps in the event of any incident or accident situations which would lead to pollution. The licensee must thus for instance precisely identify the location of each dangerous substance on its site, along with the corresponding quantities. Drums and tanks must be labelled in compliance with the European Classification, Labelling, Packaging (CLP) regulation and there must be retention areas designed to collect any spills. The NPPs must also adopt an organisation and resources to prevent pollution of the natural environment (groundwater, river, soil). For several years and at the request of ASN, EDF has been carrying out steps to improve its management of the pollution risk by working to improve the confinement of dangerous liquid substances on its sites. Through its field inspections, ASN is closely monitoring the organisational and material provisions adopted by EDF to manage the dangerous substances present in its facilities and to deal with any pollution.

This for example entails: keeping the results as they 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). Moreover, the discharge data for each site, sent to ASN by EDF, are not representative of the operating time of the facilities or activities.
