Track; not yet

Why
Vogtle is now a completed, operating asset (claimedReadiness 100) rather than an emerging technology — its register value is as the real-world cost/schedule baseline that the SMR wave is explicitly positioned against, not as something to adopt or replicate directly given its $30-34B cost and ~7-year overrun.
Next
Monitor whether the May 2025 executive order's target of 10 new large reactors with complete designs under construction by 2030 produces an actual second US large-reactor build commitment (e.g. a utility FOAK decision at an existing AP1000 site); re-evaluate Vogtle's role as baseline once a successor project breaks ground or is formally cancelled/deferred.
