Build Nuclear with Local Materials Act of 2026

The Build Nuclear with Local Materials Act of 2026 directs the Nuclear Regulatory Commission to allow the use of standard commercial steel and concrete for non-safety parts of nuclear power plants. This change aims to reduce costs and simplify construction by permitting materials that are widely available in the market rather than requiring specialized nuclear-grade versions. The rulemaking must begin within 90 days of the bill's enactment, but the Commission retains the authority to reject these materials if they pose specific safety risks or threaten public security. Ultimately, the legislation seeks to make nuclear facility construction more efficient while maintaining existing safety oversight.
