Les cahiers de l’ASN #02 - Conditions for the continued operation of EDF’s 900MWe reactors

What measures are planned by EDF? The generic phase of the safety review served to define the actions that will be implemented for each reactor to review the control of the environmental impacts . EDF has thus defined the scope of the verifications and studies to carry out, for example on the chemical and radiological status of the soils. N ormal operation of the NPPs has impacts on the environment. These impacts stem in particular from water intakes, effluent discharges, noise and vibrations, airborne dust, odours, the dispersal of pathogenic microorganisms and the production of waste. The environmental impacts are specific to each site. ENVIRONMENTAL IMPACTS OF THE FACILITIES What impacts do the NPPs have on the environment? ASN considers that the analysis and verification programme planned by EDF must be supplemented. • EDF must in particular conduct additional verifications with respect to those performed during standard operation, particularly with regard to the best techniques available. These complements concern in particular the equipment involved in the treatment of effluents and the conditioning and packaging of waste. • Furthermore, ASN has asked EDF to consolidate the facility impact studies in accordance with the form currently provided for by the Environment Code and to identify improvements that will reduce the environmental impacts. These points are set out as requirements in ASN resolution 2021-DC-0706 of 23 February 2021. THE ASN RESOLUTION Conditions for the continued operation of EDF’s 900MWe reactors • 19
