International Nuclear Energy Financing Act of 2023

This bill directs U.S. representatives at international financial institutions (like the World Bank) to use American voting influence to support financing for nuclear energy projects globally. It requires the Treasury Secretary to instruct U.S. executives at these institutions to promote nuclear energy funding, consistent with U.S. national security interests. The law includes a 10-year sunset provision, ending all authority after 2033, and allows Treasury to waive the requirement for specific projects if deemed in the national interest. It does not directly fund projects but shapes U.S. influence over how global banks allocate resources for nuclear energy.
