The bill substance matches the promise: directing NRC action on commercial-grade concrete and steel for non-safety nuclear plant structures.

Sen. Lummis formally introduced the Build Nuclear with Local Materials Act (press release dated May 15, 2026) and subsequently chaired/held a Senate EPW committee hearing to examine the bill (May 20, 2026). Those actions satisfy the claim to introduce and support the legislation to direct the NRC to pursue rulemaking on commercial-grade materials in non-safety structures. The bill has committee-level activity but not enactment; however, the promise specified introduction/support, which was met in the same term.
