Australia fortunately has a political neutral research organisation (CSIRO) whose job is to estimate the net cost benefit for various government programs.
Detail and detail on cost benefit analysis https://www.csiro.au/en/news/All/Articles/2024/December/Nucl...
Needless to say not at all cost effective to go nuclear at this point. There's no reason that wouldn't hold similarly in other nations since the scale of the difference in costs are so huge too.
Hasn't stopped certain parties from doing the same thing as Italy though, the CSIRO being credible really hurt their efforts though, Murdoch press tried & failed to discredit them with ferocity.
Worst part is, even if price comes down I think they further poisoned the idea of nuclear in Australia because their plan was brazenly to keep the coal & gas plants running in the meantime rather than spend money on wind/solar. They didn't even make an effort for their timelines and costs to be remotely believable.
