Construction on a new reactor, Flamanville 3, began on 4 December 2007.[4] The new unit is an Areva European Pressurized Reactor type and is planned to have a nameplate capacity of 1,650 MWe. EDF estimated the cost at €3.3 billion[4] and stated it would start commercial operations in 2012, after construction lasting 54 months.[5] The latest cost estimate (July 2020) is at €19.1 billion, with commissioning planned tentatively at the end of 2022.
Oh wait, that was what Wikipedia said a year ago! Now it continues:
In January 2022, more delays were announced, with fuel loading continuing until mid-2023.[4][5]

Perhaps if we account for an additional unexpected half year of delay for every year that passes, we might see it in operation in Spring 2024?
