  • Supervision of the EPR reactor: Information notice No. 14
    verified the technical and organisational measures taken by EDF for performance of these operations In particular the removal of the dam during this third step entails the dispersion of suspended solids sand earth etc into the water of the channel from the structure EDF must minimise the dispersion of these solids in order to limit their impact on the reactors in operation The licensee must in particular avoid a malfunction of the reactor cooling water filtration systems The measures taken by EDF were inspected by ASN and found to be satisfactory ASN remains attentive to the satisfactory performance of this phase of the construction site which will require the use of heavy site machinery in order to achieve the final elevation of the channel bottom Manufacture of the polar crane supports During the inspection of 14th December 2011 on the Flamanville 3 site ASN was informed of a number of deviations that occurred during the manufacture of the polar crane supports 2 EDF discovered defects in the support welds in the factory before painting then again on the Flamanville site during complementary inspections ASN asked EDF to inspect a larger number of supports in order to identify the scale of the defects These additional inspections demonstrated the presence of defects on a large number of supports so EDF decided to replace them all and have new polar crane supports manufactured At ASN s request EDF presented ASN and its technical support organisation the Institute for Radiation Protection and Nuclear Safety with the work undertaken to understand the origin of these numerous defects and to prevent identical defects occurring on other components intended for the Flamanville 3 reactor On 10 October 2012 ASN carried out an inspection to check that the steps actually taken by EDF to prevent defects of the same type on the new supports were implemented in good conditions The inspectors also examined the steps taken by EDF to analyse whether other equipment intended for Flamanville 3 was affected by similar defects The analysis did indeed reveal defects on certain items especially on several handling cranes or their carriages so EDF returned some of the equipment concerned to the factory for repair while dealing with other items in situ At the end of January 2013 EDF had completed the installation of all the new supports in the reactor building Repair of the reactor vessel closure head Since the end of 2010 AREVA NP has been involved in a process to repair deviations on the Flamanville EPR reactor vessel closure head These repairs consist in removing and then completely re doing all the welds and buttering on all the closure head adapters 3 During the second half of 2012 AREVA NP completed the welds and buttering removal phase and carried out a complete inspection of the closure head base metal In December 2012 ASN carried out checks on these inspection operations and in January 2013 conducted an exhaustive examination of the results of these operations No deviating indication was
