In a statement today the company said Mr Morvan succeeds Laurent Thieffry. His appointment will take effect on 1 January 2020.
Mr Morvan, 52, began his career at EDF in 1993. In 1998, he took a consultancy position at the Vogtle nuclear power station in the US and on his return in 2007 was appointed production manager of the Blayais nuclear power station and then director of Flamanville-1 and -2. In January 2015 he joined the Naval Group in Cherbourg before returning to EDF in the nuclear production division earlier this year.
EDF said on 9 October that its latest estimate for construction costs at Flamanville-3 was now €12.4bn.
Fuel loading at the plant will not be able to begin before the end of 2022 because of repairs to 66 welds. Work on “upgrading” 58 of the welds has already begun.
The faulty welds, discovered in 2018, forced EDF to delay the start-up date for the plant and to announce an increase of the project cost to €10.5bn and then to €10.9bn. An estimate of the cost in July 2011 was €8bn.
When construction of Flamanville-3 started in 2007, the original target launch date was 2012, which means the overall delay is now more than a decade.
