Flamanville Nuclear Power Plant Unit 3
France
This state-of-the-art reactor at the Flamanville Nuclear Power Plant was supposed to start in 2007 and be fully operational in 2012.
It’s still unfinished. Several setback, including issues with welding, steel strength and explosions on site have upped the costs. Now, they’re looking at a 2022 operational date, and a bill of $12 billion+.
