Nuclear has its pros and cons. I suggest a small partial role for it, depending on price.
In Europe, new nuclear is probably dead. Why? Capitalism. New nuclear plants cost £100 per unit, but the latest offshore wind prices are below £40 in the UK, while new solar has dropped to below £15 per unit in Spain/Portugal (actual cost, not based on 'maximum capacity'). It is also far easier to build a solar/wind farm compared to a nuclear plant.
This is also true in the USA, but to a different extent. Gas and onshore wind are just far cheaper and less problematic, and there are better govt subidies for the wind power sector.
