Title 42 › Chapter 23— DEVELOPMENT AND CONTROL OF ATOMIC ENERGY › Subchapter VIII— UNITED STATES ENRICHMENT CORPORATION PRIVATIZATION › § 2297h–10a
The United States bans, starting 90 days after May 13, 2024, most imports of unirradiated low-enriched uranium made in Russia or brought in to get around the ban. The Secretary of Energy, after talking with the Secretaries of State and Commerce, may give a temporary waiver if no other fuel can keep a reactor running or if it is in the national interest. Any waiver ends by January 1, 2028. If a waiver is given, the Energy Secretary must tell four Congressional committees (Senate Energy and Natural Resources, Senate Finance, House Energy and Commerce, and House Ways and Means). The ban does not apply to uranium imports for the Department of Energy for national security or to non-uranium isotopes. Before and after the Russian downblending deal is finished, the law sets specific yearly import limits for Russian low-enriched uranium (these limits include uranium bought as separative work units and include amounts for processing and reexport). Before the deal finishes the limits are: 16,559 kilograms total for 2008–2011, 24,839 kilograms for 2012, and 41,398 kilograms for 2013 and each year until the deal is finished. After the deal is finished the yearly caps are: 2014 — 485,279 kg; 2015 — 455,142 kg; 2016 — 480,146 kg; 2017 — 490,710 kg; 2018 — 492,731 kg; 2019 — 509,058 kg; 2020 — 514,754 kg; 2021 — 596,682 kg; 2022 — 489,617 kg; 2023 — 578,877 kg. If Russia agrees to downblend an extra 300 metric tons of weapons-origin HEU after the deal, the United States may allow an extra 4 kg of imports for each 1 kg of Russian HEU downblended in the prior year, up to 120,000 kg per year, but the Energy Secretary must verify origin and U-235 content using agreed transparency measures. The Commerce Secretary enforces the limits, must follow the Suspension Agreement rules, and must try to impose a minimal burden on the nuclear industry. Commerce can change the yearly limits if, after consulting Energy, U.S. supplies are too low, but it must tell Congress at least 45 days before the change. The import amounts are measured as if the uranium has 4.4% U-235 with a 0.3% tails assay. Downblending of non-weapons HEU may count for incentives if the Energy Secretary finds it poses a U.S. security risk; such amounts are converted into equivalents based on 90% U-235. The rules that applied before the 2024 ban end when the 2024 ban starts. The 2024 ban rules end on December 31, 2040. Defined terms in one line each: "completion of the Russian HEU Agreement" — import of uranium from downblending at least 500 metric tons of HEU weapons-origin; "downblending" — making HEU into uranium with less than 20% U-235; "highly enriched uranium (HEU) of weapons origin" — HEU that is 90% or more U-235 and verified by the Energy Secretary; "low-enriched uranium (LEU)" — uranium product with less than 20% U-235; "uranium-235" — the isotope 235U; "Russian entity" — an organization under Russian law; "Russian HEU Agreement" and "Suspension Agreement" are defined elsewhere in law.
