We built a lot of nuclear back in the 70s and 80s which we still rely on with long term operation upgrades.

For modern nuclear power the only nuclear reactor under construction in France is Flamanville 3 which is 6x over budget and 12 years late on a 6 year construction timeline.

Hinkley Point C in the UK is in a similar quagmire and Olkiluoto 3 finally got finished last year after a near 20 year construction timeline.

Politically there's some noise from conservative politicians who can't hold a climate change denial position anymore, but still need to be contrarians.

The problem is the horrendous economics.
