Greenfield nuclear is (probably) not economically relevant.

Refurbishing existing NPPs has a LCOE on-par with renewables and gives breathing room for variability issues that will otherwise be absorbed by fossil fuels until that eventual transition to storage/smart grid.

Any discussion of nuclear's costs/profitability that does not distinguish between greenfield and existing/refurbished is agendaposting since most of the costs of a NPP are upfront.
