Plans by EDF to build new nuclear reactors in Britain came under fresh scrutiny after it admitted ﬁnding serious quality control failings that could affect the safety of a prototype project in France. The French state-controlled energy group, which is leading construction of the Hinkley Point C plant in Somerset, said that defects in the welding in pipework of the European pressurised reactor it is building at Flamanville in Normandy threatened to further delay the project and to increase its costs. It is said that the welding had been signed off by contractors, but since then it had detected “quality deviation” that had forced it to alert the French nuclear regulator to what it called “a significant event”.
It comes weeks after Britain’s nuclear regulator raised concerns about sub-standard quality control checks on EDF’s supply chain for Hinkley Point C warning, too, that improvements were needed to ensure safe construction.
