§8689 Requirements for availability of funds relating to advanced naval nuclear fuel systems based on low-enriched uranium

Title 10 › Subtitle Subtitle C— - Navy and Marine Corps › Part PART IV— - GENERAL ADMINISTRATION › Chapter CHAPTER 863— - NAVAL VESSELS › § 8689

Last updated Apr 6, 2026|Official source

Summary

Only money from the Department of Energy’s defense nuclear nonproliferation account may be used for activities involving low-enriched uranium. Money from Navy shipbuilding accounts or from any other DOE atomic energy defense account (other than defense nuclear nonproliferation) cannot be used for those activities. That ban can only be changed by a law that clearly says it is changed; an appropriation must specifically cite this section to override it. Low-enriched uranium activities mean planning or doing research and development on an advanced naval nuclear fuel system based on low-enriched uranium, and buying ships that would use low-enriched uranium in their naval reactors.

(a)Low-enriched uranium activities may only be carried out using funds authorized to be appropriated or otherwise made available for the Department of Energy for atomic energy defense activities for defense nuclear nonproliferation.
(b)(1)None of the funds described in paragraph (2) may be obligated or expended to carry out low-enriched uranium activities.

(3)The prohibition in paragraph (1) may not be superseded except by a provision of law that specifically supersedes, repeals, or modifies this section. A provision of law, including a table incorporated into an Act, that appropriates funds described in paragraph (2) for low-enriched uranium activities may not be treated as specifically superseding this section unless such provision specifically cites to this section.
(c)In this section, the term “low-enriched uranium activities” means the following:
(1)Planning or carrying out research and development of an advanced naval nuclear fuel system based on low-enriched uranium.
(2)Procuring ships that use low-enriched uranium in naval nuclear propulsion reactors.
