Contrary to the picture that may be portrayed generally, the situation across Europe is very much more nuanced probably appears to be the case. Thus whether one is fighting nuclear or promoting it, one needs an objective listing of the countries involved in considering their energy policy with regards to nuclear, somewhat dispassionately presented, so as better to access the politics of each country's energy plans.
This doesn't include polls or votes done in the immediacy of Fukushima or generally popular sentiment.
Presented below is a static listing of all European countries of note -- taking the major European countries running east-west:
Spain - currently run by an anti-nuclear/pro-renewables socialist government - but all indications are that that will lose the forthcoming election very heavily. The "Partido Popular" opposition is notably quiet on nuclear, but will remove most of the subsidies for renewable generation (apart from anything else, the country's broke!)
Portugal - committed to renewables, but in deep budgetary crisis - hard to see how subsidies can continue
UK - committed to new build; just confirmed 8 sites will be permitted new build, with approx 16,000 MW of development schemes planned for five of them.
Ireland - anti-nuclear
Denmark - anti nuclear, but seems to be swimming back from wind subsidies
Sweden - notably quiet; had just lifted a moratorium on new build before Fukushima. Heavily nuclear dependent
The Netherlands - has confirmed plans to issue permits to build at two sites; six months before Fukushima had largely scrapped it's renewables targets and subsidies. Notably, no green representation in Government
Belgium - no government at the moment (actually, for the last year)- heavily nuclear dependent
France - appears to remain strongly committed to nuclear (1 under construction, another approved, another proposed).
Italy - The recent referendum will have them retaining a long-standing referendum on no nuclear, but heavily dependent on imports from France and Switzerland
Germany - "about turn" takes them back to where they were 18 months ago - no new build, and no life extensions. Very quietly, building 14,000MW of gas and coal (including lignite) plant.
Austria - as Germany
Switzerland - as Germany - heavily dependent on nuclear (50% of generation)
Czech Republic (and Slovakia) - heavily committed to new nuclear - seeking tenders for up to 8-9,000MW of new build (probably, mostly to supply Germany)
Poland - see article, appears to be building up to 6,000MW.
Finland - completing Olikuoto, and seeking tender for another 1500MW range plant.
Lithuania - seeking tenders for new build - ABWR and AP1000 in play.
Bulgaria - building Belene.
Romania - Cernavoda
Greece - anti-nuclear (and broke)
And not part of the EU, but seeking tenders for up to 8(!) reactors - Turkey.
No doubt this will change, but as of now, this is the future.
