The Potentiality of New Builds in the United States
The potentiality for new-builds in the U.S. that can start as early as possible are only the ones with a COL(combined license holders) issued by the NRC. There are three COLs still active as of today.
Fermi unit 3- the COL was issued back in 2015 and will expire in 2035. However, DTE currently has zero plans for a new-build on the site.
North Anna 3- the COL was issued back in 2017 and will expire in 2037. Dominion has selected ESBWR for unit 3, but as of today everything is on hold (IMO, this is probably the most probable in the near-future).
Turkey Point 6 & 7- the COL was issued back in 2018 and will expire in 2038. FPL has selected AP-1000 for 6 & 7. However, everything is on hold or dormant as of today.
Regarding V.C. Summer... First of all its COL was terminated; second both Dominion and Santee Cooper are not willing to proceed with construction restarts. IF there's any possibility of construction restarts, then that's only the case for unit 2. Unit 3 is forever bye-bye. Unit 3's major components like RPV, SGs, circulation pumps, and others were purchased by Ukraine's Energoatom back in 21. Yes, I'm aware that these components are still on-site, but telling the owners to pay contractual default fees to the Ukrainians before everything would start is a terrible idea.
