AP300
The one-loop modular version of the AP1000: stated at 900 MWt and 300 MWe, still in basic design and activities preceding a design-certification application.
A one-loop PWR derived from the AP1000. The current developer profile states 900 MWt and 300 MWe without identifying a net or gross basis; ARIS 2024 classified it in basic design and the NRC remains in activities preceding a future design-certification application.
