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]. 

The ASN announced today to have taken note of this evolution in the strategy, and to continue the technical dialogue with EDF to ensure the relevance of the planned schedule[2]. 

To date and on the basis of the control strategy proposed by EDF, the estimate of nuclear output in France for 2023 remains in the range 300-330TWh.
