Civil Nuclear Export Act of 2023

This bill modifies the Export-Import Bank's operations to facilitate nuclear energy exports. It expands the "Program on China and Transformational Exports" to include civil nuclear facilities, materials, and technologies, and allows such financing to count toward the Bank's lending cap (up to $50 billion). The bill also adds nuclear liability coverage, requiring the Treasury to pay claims from nuclear incidents involving Bank-supported projects, up to a statutory limit, with presidential authority for larger claims. These changes directly affect the Export-Import Bank, nuclear exporters, and U.S. government liability for nuclear-related export financing.
