On 10 March 2023, EDF proposed to the ASN (Nuclear safety authority) an evolution in its stress corrosion control strategy. EDF is accelerating the inspection of the concerned welds of the RIS and RRA systems, in order to include the elements identified on the weld repaired at Penly 1[1].

On 25 April 2023, the ASN announced to consider the schedule proposed by EDF for controls on priority welds to be appropriate[2].

To date, the estimate of nuclear output in France for 2023 remains in the range 300-330TWh.
