NuScale Changed the Game
NuScale was the first to offer the market a commerciallyviable modular, scalable light water design Modular factory manufacturing of major components and
systems lowers costs, improves quality, shortens construction Scalable incremental addition of nuclear generating capacity
produces cash flow sooner, places plant in rate base earlier Commercially viable light water technology provides clear path
