Stress corrosion continues to trouble the French nuclear fleet

 This week EDF updated its expectations for its nuclear fleet for this
winter, downgrading its output forecasts to 275-285 TWh, compared to the
previous estimate of 280-300 TWh.

The main driver of the downgraded
forecasts is a refusal by the French nuclear regulator, Autorité de
Sȗreté Nucléaire (“ASN”) to allow EDF to re-start number of reactors
with stress corrosion problems, in line with the planned schedule: Cattenom
1 (1.3 GW) will be offline for a further three and a half months until 26
February 2023; Chooz 1 (1.5 GW) will remain closed for about three months
until 29 January 2023; Penly 2 (1.33 GW) will be delayed by more than two
months until 29 January 2023; Cattenom 3 (1.3 GW) will be closed for a
further two and a half months until 26 February 2023. A couple of other
reactors are likely to have minor delays to their re-start schedules.
