I think it makes a lot of sense to build out if the construction and remediation costs are born by a persistent entity that can amortize all those expenses appropriately. It makes almost no sense to build out if your entire energy market is privatized into small entities and you lack the regulatory willpower to ensure proper cleanup funds are reserved and thus open up a loophole for companies to run with minimal costs after construction and disburse funds internally freely. Such was the case with Vermont Yankee and it is very possible (likely even) that it'd be repeated.

If you have a strong central governance authority that can ensure proper maintenance and remediation then they're wonderful... France and China have these advantages - Japan was often held up as a paragon of this approach until massive internal mismanagement was revealed with Fukushima.

I am excited to see my country (Canada) investing more into Nuclear energy as we have a track record (ignore our uranium mining please) of doing this responsibly. I don't think America could safely manage this especially with the destabilization the current administration and lack of legislative backbone has demonstrated is possible.
