The Olkiluoto 3 plant in Finland was planned to open in 2011. It's still not running, massive cost overrun. https://en.wikipedia.org/wiki/Olkiluoto_Nuclear_Power_Plant

Flamanville in France was planned to open in 2012. Still not running, massive cost overrun. https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...

Hinkley C in UK only could start construction because it got promised massive overpriced payment for electricity by the government. Speculation is this largely happens to cross-subsidize UKs nuclear weapons program.

This is all in countries that are politically relatively pro nuclear, this isn't because environmentalists are blocking the efforts.
