Unsurprising after the Windscale Fire that nuclear power is unpopular in the UK
Windscale was 60 years ago, in an air-cooled open loop pile who's only purpose was to produce plutonium and other nuclear isotopes as quickly as possible and damn the consequences.
Most people now don't even remember what Windscale was or even recognise the name. Out of those that do, a lot of them understand the different between Windscale and their local nuclear power station.
To the best of my personal knowledge, nuclear power is not unpopular in the UK, Windscale or otherwise. If anything the attitude appears to be "Get on and build the damn things!" and "Why are we letting the French/Chinese build them, I remember when the UK used to build things!".
