Alva Uprate adds generating capacity to existing nuclear plants through standardized steam and turbine upgrades.
Alva Uprate is a turnkey capacity-upgrade offering for operators of existing nuclear power plants. Its design replaces steam generators and adds a second turbine plant outside the protected area, converting additional steam into electricity. Alva states a current design target of 250–300 MWe of additional generating capacity per reactor.
The offering combines engineering, licensing, procurement, construction, and commissioning in a standardized delivery package. A dual-redundant digital control system coordinates the reactor and both turbine systems. Utilities and large electricity customers are its stated target buyers.
