Electricité de France has been given until 30 September to implement preventative safety measures in steam generators at its French nuclear reactors including plugging tubes affected by an anomaly in anti-vibration measures.
France's Nuclear Safety Authority (Autorité De Sûreté Nucléaire, ASN) has released a letter issued to the utility on 24 April calling for some steam generator tubes to be plugged to prevent the risk of their rupturing. The company must also implement enhanced measures to detect leaks between primary and secondary coolant circuits pending the completion of the plugging work.
