3. Advanced Concrete
"We spent a lot of time looking at concrete," Petti said. "There are all sorts of innovations in the world of concrete."
Nuclear plants could benefit from innovations such as self-consolidating concrete, which eliminates the need to consolidate concrete mechanically, and new forms of concrete that are framed by steel plates and reinforced through means other than rebar.
"Pouring concrete is one of the most cost-intensive activities on the site," Petti said. "The guys who build the form works—it’s the largest single craft on the light water reactor build."
