A BILL

To require the Nuclear Regulatory Commission to allow the use of

Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,

SECTION 1. SHORT TITLE.

This Act may be cited as the ``Build Nuclear with Local Materials 
Act of 2026''.

SEC. 2. USE OF COMMERCIAL-GRADE STEEL AND CONCRETE.

(a) In General.--Not later than 90 days after the date of enactment 
of this Act, the Nuclear Regulatory Commission (referred to in this 
section as the ``Commission'') shall initiate a rulemaking that 
authorizes the use of commercial-grade steel and concrete in non-
safety-related structures at nuclear power plants, unless, subject to 
subsection (b), the Commission determines that stricter material 
standards are necessary to address a specific safety risk.
(b) Determination.--The Commission may make a determination under 
subsection (a) that stricter material standards are necessary to 
address a specific safety risk if the Commission determines that not 
using a stricter material standard would be contrary to the common 
defense and security and adequate protection of the public health and 
safety (within the meaning of section 182 a. of the Atomic Energy Act 
of 1954 (42 U.S.C. 2232(a))).
