  DE-FOA-0002691 Converting UNF Radioisotopes into Energy (CURIE) Funding Opportunity Announcement (FOA) 4/14/2022 09:30 AM ET 7/21/2022 09:30 AM ET

DE-FOA-0002691: Converting UNF Radioisotopes into Energy (CURIE)

The program goal of Converting UNF Radioisotopes into Energy (CURIE) is to enable commercially viable reprocessing of used nuclear fuel (UNF) from the current light water reactor (LWR) fleet by resolving key gaps/barriers in reprocessing technologies, process monitoring, and facility design. The actinides in LWR UNF would ideally be reprocessed into feedstock that would be used to fuel advanced nuclear reactors (ARs), while other commercially valuable materials would be harvested for industrial and medical uses. Projects funded under CURIE will develop innovative separations technologies, process monitoring techniques for special nuclear material (SNM), and/or equipment designs that will significantly improve the economics and process monitoring of reprocessing technologies while dramatically reducing the volume of high-level waste (HLW) from LWR UNF requiring disposal. Specifically, CURIE is interested in separations technologies, process monitoring to enable predictive material accountancy, innovative equipment designs, and systems analyses that satisfy one or more of the global program metrics without negatively impacting other program metrics: (1) significantly (i.e., at least an order of magnitude) reduce the volume of LWR HLW requiring permanent disposal, (2) maintain disposal costs in the range of 0.1¢/kilowatt-hour (kWh), (3) provide a 1¢/kWh fuel cost for a 200 metric tons heavy metal (MTHM)/yr nth-of-a-kind (NOAK) facility, (4) enable in situ SNM process monitoring approaches that predict, within 1% uncertainty and under representative conditions, the post-process material accountancy, and (5) enable UNF separations that do not produce pure plutonium streams.
