The Department of Energy's National Nuclear Security Administration (NNSA) is seeking capabilities for the purification and reprocessing of lithium hydride (LiH) material. The objective is to recycle approximately 1,500 to 5,000 kg of LiH annually, which involves a multi-step process including cleaning, purification into lithium chloride (LiCl), conversion to lithium metal, and hydriding to regenerate LiH, while also salvaging lithium from waste streams for weapons-grade material. This procurement is critical for maintaining the supply of high-purity lithium for national security applications. Interested parties can contact Fernando F. Soto-Perez at fernando.soto-perez@nnsa.doe.gov or by phone at 202-586-6681 for further details.
