tv_txt: II 117th CONGRESS 2d Session S. 4242 IN THE SENATE OF THE UNITED STATES May 18 (legislative day, May 17), 2022 Mr. Tuberville (for himself and Mr. Marshall ) introduced the following bill; which was read twice and referred to the Committee on Energy and Natural Resources A BILL To provide for the preservation and storage of uranium-233 to foster development of thorium molten-salt reactors, and for other purposes.

1. Short title This Act may be cited as the Thorium Energy Security Act of 2022 . 2. Findings Congress makes the following findings: (1) Thorium molten-salt reactor technology was originally developed in the United States, primarily at the Oak Ridge National Laboratory in the State of Tennessee under the Molten-Salt Reactor Program. (2) Before the cancellation of that program in 1976, the technology developed at the Oak Ridge National Laboratory was moving steadily toward efficient utilization of the natural thorium energy resource, which exists in substantial amounts in many parts of the United States, and requires no isotopic enrichment. (3) The People's Republic of China is known to be pursuing the development of molten-salt reactor technology based on a thorium fuel cycle. (4) Thorium itself is not fissile, but fertile, and requires fissile material to begin a nuclear chain reaction. This largely accounts for its exclusion for nuclear weapons developments. (5) Uranium-233, derived from neutron absorption by natural thorium, is the ideal candidate for the fissile material to start a thorium reactor, and is the only fissile material candidate that can minimize the production of long-lived transuranic elements like plutonium, which have proven a great challenge to the management of existing spent nuclear fuel. (6) Geologic disposal of spent nuclear fuel from conventional nuclear reactors continues to pose severe political and technical challenges, and costs United States taxpayers more than $500,000,000 annually in court-mandated payments to electrical utilities operating nuclear reactors. (7) The United States possesses the largest known inventory of separated uranium-233 in the world, aggregated at the Oak Ridge National Laboratory. (8) Oak Ridge National Laboratory building 3019 was designated in 1962 as the national repository for uranium-233 storage, and its inventory eventually grew to about 450 kilograms of separated uranium-233, along with approximately 1,000 kilograms of mixed fissile uranium from the Consolidated Edison Uranium Solidification Program (commonly referred to as CEUSP ), divided into approximately 1,100 containers. (9) The Defense Nuclear Facilities Safety Board issued Recommendation 97–1 (relating to safe storage of uranium-233) in 1997 because of the possibility of corrosion or other degradation around the storage of uranium-233 in a building that was built in 1943. (10) In response, the Department of Energy published Decision Memorandum No. 2 in 2001 concluding that no Department of Energy programs needed uranium-233 and directed that a contract be placed for disposition of the uranium-233 inventory and decommissioning of its storage facility. (11) The Department of Energy awarded a contract for the irreversible downblending of uranium-233 with uranium-238 and its geologic disposal in Nevada, which downblending would create a waste form that would pose radiological hazards for hundreds of thousands of years, rather than to consider uranium-233 as a useful national asset. (12) All 1,000 kilograms of CEUSP uranium-233-based material have been dispositioned (but not downblended) but those containers had little useful uranium-233 in them. The majority of separated and valuable uranium-233 remains uncontaminated by uranium-238 and suitable for thorium fuel cycle research and development. That remaining inventory constitutes the largest supply of uranium-233 known to exist in the world today. (13) The United States has significant domestic reserves of thorium in accessible high-grade deposits, which can provide thousands of years of clean energy if used efficiently in a liquid-fluoride reactor initially started with uranium-233. (14) Recently (as of the date of the enactment of this Act), the Department of Energy has chosen to fund a series of advanced reactors that are all dependent on initial inventories and regular resupplies of high-assay, low-enriched uranium. (15) There is no domestic source of high-assay, low-enriched uranium fuel, and there are no available estimates as to how long the development of a domestic supply of that fuel would take or how expensive such development would be. (16) The only viable source of high-assay, low-enriched uranium fuel is through continuous import from sources in the Russian Federation. (17) The political situation with the Russian Federation as of the date of the enactment of this Act is sufficiently uncertain that it would be unwise for United States-funded advanced reactor development to rely on high-assay, low-enriched uranium since the Russian Federation would be the primary source and can be expected to undercut any future United States production, resulting in a dependency on high-assay, low-enriched uranium from the Russian Federation. (18) The United States has abandoned the development of a geologic repository at Yucca Mountain and is seeking a consenting community to allow interim storage of spent nuclear fuel, but valid concerns persist that an interim storage facility will become a permanent storage facility. (19) Without a closed fuel cycle, high-assay, low-enriched uranium-fueled reactors inevitably will produce long-lived wastes that presently have no disposition pathway. (20) The United States possesses enough uranium-233 to support further research and development as well as fuel the startup of several thorium reactors. Thorium reactors do not require additional fuel or high-assay, low-enriched uranium from the Russian Federation. (21) Continuing the irreversible destruction of uranium-233 precludes privately funded development of the thorium fuel cycle, which would have long term national and economic security implications. 3. Sense of Congress It is the sense of Congress that— (1) it is in the best economic and national security interests of the United States to resume development of thorium molten-salt reactors that can minimize long-lived waste production, in consideration of— (A) the pursuit by the People’s Republic of China of thorium molten-salt reactors and associated cooperative research agreements with United States national laboratories; and (B) the present impasse around the geological disposal of nuclear waste; (2) that the development of thorium molten-salt reactors is consistent with section 1261 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 ( Public Law 115–232 ; 132 Stat. 2060), which declared long-term strategic competition with the People's Republic of China as a principal priority for the United States ; and (3) to resume such development, it is necessary to relocate as much of the uranium-233 remaining at Oak Ridge National Laboratory as possible to new secure storage. 4. Definitions In this Act: (1) Congressional defense committees The term congressional defense committees has the meaning given that term in section 101(a) of title 10, United States Code. (2) Downblend The term downblend means the process of adding a chemically identical isotope to an inventory of fissile material in order to degrade its nuclear value. (3) Fissile material The term fissile material refers to uranium-233, uranium-235, plutonium-239, or plutonium-241. (4) High-assay, low-enriched uranium The term high-assay, low-enriched uranium (commonly referred to as HALEU ) means a mixture of uranium isotopes very nearly but not equaling or exceeding 20 percent of the isotope uranium-235. (5) Transuranic element The term transuranic element means an element with an atomic number greater than the atomic number of uranium (92), such as neptunium, plutonium, americium, or curium. 5. Preservation of uranium-233 to foster development of thorium molten-salt reactors The Secretary of Energy shall preserve uranium-233 inventories that have not been contaminated with uranium-238, with the goal of fostering development of thorium molten-salt reactors by United States industry. 6. Storage of uranium-233 (a) Report on long-Term storage of uranium-233 Not later than 120 days after the date of the enactment of this Act, the Secretary of Energy, in consultation with the heads of other relevant agencies, shall submit to Congress a report identifying a suitable location for, or a location that can be modified for, secure long-term storage of uranium-233. (b) Report on interim storage of uranium-233 Not later than 120 days after the date of the enactment of this Act, the Chief of Engineers shall submit to Congress a report identifying a suitable location for secure interim storage of uranium-233. (c) Report on construction of uranium-233 storage facility at Redstone Arsenal Not later than 240 days after the date of the enactment of this Act, the Chief of Engineers shall submit to Congress a report on the costs of constructing a permanent, secure storage facility for uranium-233 at Redstone Arsenal, Alabama, that is also suitable for chemical processing of uranium-233 pursuant to a public-private partnership with thorium reactor developers. (d) Funding Notwithstanding any other provision of law, amounts authorized to be appropriated or otherwise made available for the U233 Disposition Program for fiscal year 2022 or 2023 shall be made available for the transfer of the inventory of uranium-233 to the interim or permanent storage facilities identified under this section. 7. Interagency cooperation on preservation and transfer of uranium-233 The Secretary of Energy, the Secretary of the Army (including the head of the Army Reactor Office), the Secretary of Transportation, the Tennessee Valley Authority, and other relevant agencies shall— (1) work together to preserve uranium-233 inventories and expedite transfers of uranium-233 to interim and permanent storage facilities; and (2) in expediting such transfers, seek the assistance of appropriate industrial entities. 8. Report on use of thorium reactors by People's Republic of China Not later than 180 days after the date of the enactment of this Act, the Comptroller General of the United States, in consultation with the Secretary of State, the Secretary of Defense, and the Administrator for Nuclear Security, shall submit to Congress a report that— (1) evaluates the progress the People’s Republic of China has made in the development of thorium-based reactors; (2) describes the extent to which that progress was based on United States technology; (3) details the actions the Department of Energy took in transferring uranium-233 technology to the People's Republic of China; and (4) assesses the likelihood that the People's Republic of China may employ thorium reactors in its future navy plans. 9. Report on medical market for isotopes of uranium-233 Not later than 180 days after the date of the enactment of this Act, the Director of the Congressional Budget Office, after consultation with institutions of higher education and private industry conducting medical research and the public, shall submit to Congress a report that estimates the medical market value, during the 10-year period after the date of the enactment of this Act, of actinium, bismuth, and other grandchildren isotopes of uranium-233 that can be harvested without downblending and destroying the uranium-233 source material. 10. Report on costs to United States nuclear enterprise Not later than 180 days after the date of the enactment of this Act, the Director of the Congressional Budget Office, after consultation with relevant industry groups and nuclear regulatory agencies, shall submit to Congress a report that estimates, for the 10-year period after the date of the enactment of this Act, the costs to the United States nuclear enterprise with respect to— (1) disposition of uranium-233; (2) payments to nuclear facilities to store nuclear waste; and (3) restarting the manufacturing the United States of high-assay, low-enriched uranium.
