The nuclear pressure equipment regulation requires that the manufacturer limits the risks of heterogeneity in the materials used for manufacturing the components most important for safety. In order to address this technical requirement, AREVA carried out chemical and mechanical tests on a vessel head similar to that of the Flamanville EPR. The results of these tests, in late 2014, revealed the presence of a zone in which there was a high carbon concentration, leading to lower than expected mechanical toughness1 values. Initial measurements confirmed the presence of this anomaly in the reactor vessel head and reactor vessel bottom head of the Flamanville EPR. ASN received a proposal from AREVA for a further detailed test campaign on a representative vessel head, starting in April 2015, in order to precisely identify the location of the zone concerned and its mechanical properties. ASN will make a decision on the acceptability of the test programme, check its correct performance and examine the file to be submitted by AREVA to demonstrate the robustness of the Flamanville EPR reactor vessel. It will also call on the services of its technical support organisation, IRSN (Institute of Radiation Protection and Nuclear Safety), and the Advisory Committee of Experts for Nuclear Pressure Equipment.“If the weakness of the vessel is confirmed, I wouldn’t hold out much hope for EPR’s survival,” a former nuclear safety official told Le Parisien. We discovered with the Rafale deal that India will simply succumb to an agreement against our interest if the other side holds out. We now seem to be discovering that India under Modi is so eager to claim credit for opportunities started but left incomplete by the previous regime that it does not even care for practical considerations for cost or safety. All this, of course is apart from the staunch opposition of locals at the site of the proposed plant – which neither government cared or cares much about, though I suppose the new Land Grab Ordinance (also known as the Land Acquisition Ordinance) will leave the locals with little right over their own land to refuse “development”. It is unclear what exactly Modi claims to be proud of in concluding such a deal.
