Nuclear chiefs say 22 components in the pressure vessel “heart” of the Sizewell B power station were made at a discredited French forge – but all are safe and will not be removed. The parts have been operating satisfactorily since 1995 and have now been thoroughly inspected by EDF Energy and independent experts and given a clean bill of health. Concerns arose following the revelation from engineering firm Areva that information on the safety of the reactor pressure vessels it has been manufacturing for nuclear plants for the past 50 years at Creusot Forge in France was either missing or wrong, and the company could not rule out falsification. Andrew Holt, of the Office for Nuclear Regulation (ONR), told the Sizewell Stakeholder Group (SSG), that confirmation had been sought from Areva to identify all the components in Sizewell B that might have been affected by the anomalies.; There were 22 components in the reactor pressure vessel and steam generator but Areva had said that it had not identified any anomalies with any of those elements. The ten-year inspection carried out of the pressure vessel in the past few weeks as part of a planned shutdown of the power station had inspected every part and found no reportable defects.
