This legislation, known as the International Nuclear Energy Financing Act of 2025 , aims to significantly increase support for nuclear energy development through international financial institutions. It instructs the Secretary of the Treasury to direct U.S. Executive Directors at entities such as the World Bank and the European Bank for Reconstruction and Development to advocate for the removal of prohibitions against financial and technical assistance for nuclear energy. This advocacy specifically targets nuclear technologies that meet or exceed the quality standards prevalent in the United States or its allies, while also building internal capacity within these banks to assess and deliver such assistance. A key provision of the bill is the establishment of Nuclear Energy Assistance Trust Funds at these international financial institutions. These trust funds are designed to provide financial and technical assistance for the generation and distribution of nuclear energy in borrowing countries. Their purposes include ensuring competitive financing terms to counter credit extended by non-OECD countries and exclusively supporting nuclear energy technologies that adhere to high quality standards. Both the advocacy mandate and the trust fund provisions are set to sunset 10 years after the act's enactment. Furthermore, the bill requires the Chairman of the National Advisory Council on International Monetary and Financial Policies to include in its annual report a description of progress made in promoting nuclear energy assistance by multilateral development banks and in establishing or operating these new trust funds for a seven-year period.
