Edf: Update on Framatome’s deviation from technical standards
governing the manufacture of nuclear-reactor components
PRESS RELEASE18 September
2019
Update on Framatome’s deviation from
technical standards governing the manufacture of nuclear-reactor
components
On the 9th of September 2019, EDF informed
France’s nuclear regulatory authority of its initial investigations
concerning the deviation from a post-weld detensioning
heat-treatment process applied to certain nuclear-reactor
components.
EDF and Framatome have since identified 16 steam
generators installed on six operating reactor units: reactors no. 3
and 4 at Blayais, reactor no. 3 at Bugey, reactor no. 2 at
Fessenheim, reactor no. 4 at Dampierre-en-Burly and reactor no. 2
at Paluel.
At this stage of the technical investigations
being carried out on these components, EDF believes that the
observed deviations do not adversely affect the components’ fitness
for service and do not require immediate action.
The components that are not yet in service are
the 4 steam generators and the pressuriser at the Flamanville-3
EPR, as well as 3 new steam generators that have not yet been
installed and that were manufactured for the purpose of replacing
the steam generators on reactor units no. 5 and 6 at
Gravelines.
EDF and FRAMATOME are continuing to conduct
their technical investigations with extreme diligence and will keep
the nuclear regulatory authority informed on a regular basis.
