I must admit I haven't read all the comments but I have been watching the news and regardless of what is being said here on estimates to build nuclear power plants and their cost, you only have to look at real world costs and timelines. They are simply extraordinary. Extremely long times to get up and running, sometimes more than double the time originally estimated and cost blow-outs of more than 100%.
I'd accept that having them as a back-up in times of need is acceptable but not at the expense of getting more wind and solar/battery online.
