ASP Isotopes Inc. (ASPI) announced on Friday that its subsidiary Quantum Leap Energy LLC has signed a memorandum of understanding with a publicly traded U.S. power company that operates nuclear energy plants.
The agreement outlines potential collaboration to strengthen domestic nuclear fuel capabilities and support next-generation reactor technologies in the United States.
Under the preliminary agreement, the unnamed utility will explore ways to support Quantum Leap Energy’s plan to develop advanced nuclear fuel cycle facilities within the U.S.
The planned sites would focus on producing specialized uranium fuels. The proposed facilities are intended to manufacture high-assay low-enriched uranium (HALEU) and low-enriched uranium plus (LEU+).
Both fuels are increasingly viewed as essential for the next generation of nuclear reactors, including small modular reactors that require higher enrichment levels than traditional nuclear plants.
ASP Isotopes stock inched 0.7% higher in Friday’s premarket. On Stocktwits, retail sentiment around the stock changed to ‘neutral’ from ‘bearish’ territory amid ‘low’ message volume levels.

In addition to supporting future reactor designs, the company expects LEU+ fuel could also be supplied to existing nuclear facilities currently using conventional low-enriched uranium.
The agreement reflects a broader push to expand U.S.-based nuclear fuel production capacity. Demand for enriched uranium is rising as developers work on advanced reactors and small modular designs. Industry participants and policymakers have emphasized the need for domestic production to reduce reliance on overseas suppliers.
In May 2024, the United States passed the Prohibiting Russian Uranium Imports Act, which will stop all nuclear fuel imports from Russia beginning in 2028.
ASPI stock has gained over 25% in the last 12 months.
