The French have, but in all likelihood any new nuclear capacity is going to go online way too late and cost way too much. Flamanville has a delay of 11 years, Olkiluoto construction is turning 20 this year and is still in evaluations. All have colossal cost overruns too. Nuclear is pretty dead in the water right now in that it's currently not possible to actually get them built.
The US have approved modular nuclear. But might be too little too late for Europe. And it’s nimby approach to certain things. Especially protectionist France. Can’t imagine they’d ever give a nuclear contract to anyone other than EdF
It remains to be seen how that will go. Pro-nuke people were pretty stoked for Olkiluoto/Flamanville/Hinkley Point too and that didn't work out so well despite being a much more proven technology and form factor. I think it's way to soon to consider SMRs a solution to demand for green energy, right now it's more like a big experiment with highly uncertain outcome.
