    the defects appeared to be 10 cm high 40 cm deep and about 10 centimetres long except for one of them which was 4 m long The analysis sent by EDF to ASN identified the fact that rain which was heavier than expected at the time of pouring had created run off leading to an accumulation of water and fine particles in certain areas as the accumulated water could not drain away owing to the small diameter of the orifices made in the formwork These areas did not therefore receive the expected density of aggregate EDF presented ASN with a repair strategy involving the injection of microconcrete comprising aggregates of smaller dimension so as to optimise following of the contours of the removed concrete volumes To prevent this deviation from happening again EDF has reinforced the measures to allow the drainage of run off water and to this end it improved the concreting procedure used ASN issued no observation on this strategy and its implementation by EDF was considered by ASN to be satisfactory The EPR double wall containment Enlarge the visual Deviations concerning pre stressing of the reactor building inner containment The building housing the EPR reactor comprises a double wall containment The function of the outer containment made of reinforced concrete is to protect the equipment from the effects of an external hazard The inner containment is made of pre stressed concrete which enables it to withstand the pressure rises liable to occur in an accident situation This pre stressing is by means of cables inserted into sheaths incorporated into the concrete then tensioned so as to apply a compression force to the concrete which would counter any internal over pressure Finally a cement grout is injected into the sheaths so as to protect the cables from corrosion Strands oilig Enlarge the visual In early 2014 EDF informed ASN of two deviations which had occurred during the pre stressing operations The first concerned the injection of grout into the sheath of a horizontal cable The quantity of grout prepared in the injection device was insufficient and an incorrect decision was taken to use water to push the grout into the injection device This then led to the injection of a mixture of water and grout into the pre stressing sheath giving rise to risks of long term corrosion of the strands 1 The second deviation concerned the tensioning of a vertical cable the various strands making up the cable were tensioned to significantly different values which reduces the effectiveness of the pre stressing The Caen division carried out an inspection on 17 th July 2014 to examine how EDF dealt with these deviations The inspectors found that the incidents which affected the pre stressing work were mainly the result of documentary inadequacies and non compliance with procedures by an outside contractor They did however observe that EDF s management of these deviations was appropriate and in accordance with its internal procedures EDF in particular informed ASN of the
