Saying it's vital is not going to help. the question is : how much time and money do we have to be carbon free. Is nuclear power helping to reach that target or not ?

Saying it's vital is equivalent to saying "do we really really really want it ?" And of course, a lot of uniformed opinions will come up...

let me remind you that 1/ nuclear is bad when it breaks 2/ solar/wind is hyper expensive to build in quantities large enough to cover our needs

So which evil will we choose ?
