Re: Feels a bit late now...
I'd add that without government being on-side and supporting it - by policy, not necessarily funding - it would be a massive risk. Just think if you've just invested [insert large value here] and then the government turns round and bans nuclear as happened in Germany as a knee jerk reaction driven by the greens after Fukashima. I suspect there's been more radioactivity released from the extra coal burned (but it's OK, that happened in Poland so doesn't count) to replace the nuclear.
And over here, we've had a bit of a roller coaster ride in terms of political support for nuclear. Traditionally Labour have been agin it, while the Tories have been "sort of supportive but frightened of the minorities who shout very loudly". But as you point out, there's nothing like a good crisis to persuade people to stop kicking that tin can down the road.
