# §6123. Acceleration of depleted uranium manufacturing processes

- (a) **Acceleration of Manufacturing.—** The [Administrator](/usc/10/2700.md?p=3) shall require the nuclear security enterprise to accelerate the modernization of manufacturing processes for depleted uranium by 2030 so that the nuclear security enterprise—
  - (1) demonstrates bulk cold hearth melting of depleted uranium alloys to augment existing capabilities on an operational basis for war [reserve](/usc/10/101.md?p=c-6) [components](/usc/10/3011.md?p=13);
  - (2) manufactures, on a repeatable and ongoing basis, war [reserve](/usc/10/101.md?p=c-6) depleted uranium alloy [components](/usc/10/3011.md?p=13) using net shape casting;
  - (3) demonstrates, if possible, a production [facility](/usc/10/2700.md?p=2) to conduct routine operations for manufacturing depleted uranium alloy [components](/usc/10/3011.md?p=13) outside of the current perimeter security fencing of the Y-12 [National Security](/usc/10/801.md?p=16) Complex, Oak Ridge, Tennessee; and
  - (4) has available high purity depleted uranium for the production of war [reserve](/usc/10/101.md?p=c-6) [components](/usc/10/3011.md?p=13).
- (b) **Annual Briefing.—** Not later than March 31, 2023, and annually thereafter through 2030, the [Administrator](/usc/10/2700.md?p=3) shall provide to the [congressional defense committees](/usc/10/101.md?p=a-16) a briefing on—
  - (1) progress made in carrying out [subsection (a)](#a);
  - (2) the cost of activities conducted under such subsection during the preceding fiscal year; and
  - (3) the ability of the nuclear security enterprise to convert depleted uranium fluoride hexafluoride to depleted uranium tetrafluoride.
