3 Act of 2023’’. 

4 SEC. 2. U.S. NUCLEAR FUEL SECURITY INITIATIVE. 

5 (a) SENSE OF CONGRESS.—It is the sense of Con6 gress that— 

7 (1) the Department should— 

8 (A) prioritize activities to increase domes9 tic production of low-enriched uranium; and 

10 (B) accelerate efforts to establish a domes11 tic high-assay, low-enriched uranium enrich12 ment capability; and 

13 (2) if domestic enrichment of high-assay, low14 enriched uranium will not be commercially available 

15 at the scale needed in time to meet the needs of the 

16 advanced nuclear reactor demonstration projects of 

17 the Department, the Secretary shall consider and 

18 implement, as necessary— 

19 (A) all viable options to make high-assay, 

20 low-enriched uranium produced from inven21 tories owned by the Department available in a 

22 manner that is sufficient to maximize the po23 tential for the Department to meet the needs 

24 and schedules of advanced nuclear reactor de25 velopers, without impacting existing Depart26 ment missions, until such time that commercial

•S 452 RS

1 enrichment and deconversion capability for 

2 high-assay, low-enriched uranium exists at a 

3 scale sufficient to meet future needs; and 

4 (B) all viable options for partnering with 

5 countries that are allies or partners of the 

6 United States to meet those needs and sched7 ules until that time.

4 partnering with countries that are allies or partners 

5 of the United States if domestic options are not 

6 practicable; 

7 (5) to ensure that, in the event of a supply dis8 ruption in the nuclear fuel market, a reserve of nu9 clear fuels is available to serve as a backup supply 

10 to support the nuclear nonproliferation and civil nu11 clear energy objectives of the Department; 

12 (6) to support enrichment, deconversion, and 

13 reduction technology deployed in the United States; 

14 and 

15 (7) to ensure that, until such time that domes16 tic enrichment and deconversion of high-assay, low17 enriched uranium is commercially available at the
