For France (and I imagine it's similar for other countries), EU contributions are a smidgen under 1% of GDP. I can't imagine that makes the decisive difference here. And in any case, since the EU still gets more of its energy from nuclear than the US does they'd be doing a piss-poor job of it.
In fact, looking at the figures, the only countries worldwide that get more energy from nuclear than the EU _and_ aren't part of the EU are Ukraine (55%), South Korea (28%), Switzerland (29%), and Armenia (25%). And both Switzerland and Ukraine are synchronised with the greater European grid!
