From my point of view you have to be pretty 'fundamentalist ' to support nuclear. Every country that has nuclear has accidents.
Why is it that pro-nuclear people always like to ignore the fact that nuclear is the most expensive option and that there is no good place to store the waste. You could sell it to the Italian mafia though, they have disposed of it in the past.
And the dangers are never sufficiently dealt with, luckily terrorists have never attempted to fly plans in to nuclear power stations with the accuracy of the plane that hit the pentagon.
Terrorists, storage, cost, earthquakes, profit motive, tsunamis, large solar flares, disgruntled nut job employees, rogue govt hackers, organised crime, I can't be bothered to go in to all of these in detail but I'm sure there are more reasons why nuclear is a bad idea.
When was the last time a coal fired power station exploded leaving land uninhabitable and the ocean unfishable and with astronomical clean-up costs?
If we put a fraction of what we spend on nuclear in to large scale energy storage R+D and implement it then we could use wind, solar, tidal etc a lot more. UK could be powered from wind alone.
