- 17 - EDF plans to reinforce the heat sink safety frame of reference by early 2013. 4. With regard to electrical power supplies, the ASN inspectors judged the EDF sites to be on the whole satisfactory but nonetheless there was room for improvement on the following points: rigour in utilisation of the operating and maintenance documents (filling out of operational documents, updating of maintenance programmes); physical condition of certain fuel storage equipment (piping corrosion, water infiltration); management of fluids needed by the electricity generating sets (periodic analyses); periodic inspections associated with the TAC (combustion turbine) on certain sites. 5. Operations in an accident situation could be improved. The PUI (on-site emergency plan) arrangements implemented by the sites are satisfactory. ASN finds that EDF needs to improve management of the fallback stations and certain agreements with outside organisations.
