  • New European Approach for cross-border Emergency Preparedness
    emergency planning has evolved in all states mostly without giving great priority to cross border issues This has led to sometimes significant differences In case of a nuclear emergency in Europe these differences can potentially create significant difficulties in emergency management especially if the location of the emergency is close to a national border Coordinated protective actions along adjacent national borders are therefore highly desirable During the very early phase of a nuclear accident the status of the reactor and the estimation of the amount of radioactivity released the source term are likely to be difficult to assess correctly Thus uncertainties in terms of dose estimation and overall radiological impact cannot be excluded Also in such situations with much uncertainty the decision maker must be able to take appropriate health protection measures This inevitably leaves room for flexibility in decisions even where there is a rigid national framework The HERCA WENRA Approach makes use of this freedom for coordination between neighbouring countries in order to align early decisions across borders As a result the respective national arrangements do not necessarily need to be changed Instead the prevailing differences are respected and taken into account and the response is based on compromise solutions which are understandable and explainable in each given situation The principles The new approach relies on the following principles shared technical understanding coordination and mutual trust It does not propose a uniform cross border framework The main strategy is to aim at an alignment of the response between neighbouring countries or neighbouring territories This is supported by early information exchanges using existing bilateral and international arrangements as far as possible A three step approach The HERCA WENRA Approach is divided into 3 steps the preparedness phase the early phase and the later phase Step 1 The aim of the preparedness step is to achieve and maintain a shared understanding of the existing national emergency arrangements by developing or improving already existing bilateral and multilateral arrangements to test these arrangements and implement improvements Step 2 In the early phase of an accident the proposed HERCA WENRA Approach foresees rapid information exchange through existing bilateral and international arrangements If the response is thought consistent the neighbouring countries can recommend their governments to follow these recommendations i e adopt the principle We do the same as the accident country in the first hours of the accident Step 3 In the later phase a common situation report accepted by all impacted countries including the accident country will further support coordinated protective actions Emergency preparedness for severe accidents The general mechanism of the new approach is independent of the accident scenario and includes severe accidents like Fukushima The Fukushima accident was a reminder that a severe nuclear accident cannot be completely excluded anywhere in the world including Europe Considering the safety level of European nuclear power plants and their improvements resulting from the lessons learned from various events including the Fukushima disaster the probability of such a severe accident is very low But

  • EPR Newsletter n°16
    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 deviations detected and suspended the pre stressing work as a precaution until the causes of the deviations could be determined and a remedial plan of action
