MESQUITE, Nev, Nov. 12, 2026 (GLOBE NEWSWIRE) — MESQUITE, Nev., November 12, 2026  (GLOBE NEWSWIRE) – Nuclear Diamond Batteries, Inc. (OTCID: NDBI) (“NDBI”), a developer of betavoltaic nuclear diamond battery technology, today announced that its majority-owned subsidiary, AtomiQ, Inc. (“AtomiQ”), has signed a Memorandum of Understanding (MOU) with Curio Legacy Ventures, Inc., doing business as Curio (“Curio”), a Washington, D.C.-based nuclear technology company developing its patented NuCycle® used nuclear fuel recycling process.

The MOU establishes a framework for the companies to explore technical collaboration and potential future supply of strontium-90 (Sr-90) and americium-241 (Am-241), two radioisotopes with potential applications in long-duration power technologies. Through its NuCycle® process, Curio is developing the capability to recover valuable materials, including radioisotopes, from used nuclear fuel, creating opportunities to establish new domestic supply chains for strategic nuclear materials.

The companies intend to evaluate how Curio’s isotope recovery capabilities could support AtomiQ’s development of diamond and carbon-based nuclear-voltaic power sources. The collaboration will initially focus on assessing technical feasibility, isotope characteristics, potential supply requirements, and the regulatory considerations associated with future commercial applications.

Key areas of potential collaboration include:

  • Radioisotope supply: Exploring a potential domestic supply pathway for Sr-90 and Am-241 recovered through Curio’s NuCycle technology.
  • Technical evaluation: Assessing isotope specifications, characterization requirements, and potential suitability for AtomiQ’s nuclear battery technologies.
  • Regulatory coordination: Evaluating licensing, material handling, packaging, transportation, and end-of-life disposition requirements associated with potential future supply.
  • Commercial opportunities: Identifying potential government, research, and commercial applications that could benefit from domestically sourced radioisotopes and long-duration nuclear power systems.

The MOU provides a preliminary framework for evaluating these opportunities. Any future isotope supply, technical work, material transfers, or commercial arrangements would be subject to separate agreements, successful technical validation, applicable regulatory authorizations, and facility readiness. The MOU does not establish committed purchases, supply volumes, delivery schedules, or a contract value.

“Reliable access to appropriately characterized radioisotopes is an important part of advancing our nuclear battery technology, and domestic sources of strontium-90 and americium-241 have historically been limited,” said Dr. Greg Rubin, Chief Executive Officer of AtomiQ, Inc. “This agreement gives us a structured path to qualify material, align technical requirements and plan supply as our development program progresses, and it addresses the full life cycle of the material, from delivery to take-back. We look forward to working with the Curio team.”

“Curio’s patented NuCycle technology is designed to transform used nuclear fuel into valuable resources, including critical radioisotopes that can support new industries and advanced technologies,” said Edward McGinnis, President and Chief Executive Officer of Curio. “Our collaboration with AtomiQ highlights the growing commercial opportunities for recovered isotopes and the importance of establishing a reliable domestic supply chain. As Curio advances toward commercialization, relationships like this demonstrate the potential for nuclear fuel recycling to strengthen American technological leadership, economic competitiveness, and national security.”

Market Opportunity: Long-Duration Power for Space, Defense, and Remote Systems

Nuclear battery technologies offer the potential to provide long-duration power in environments where conventional batteries are difficult or impractical to replace or recharge. Applications under development across the industry include space exploration, defense systems, remote sensing, subsea infrastructure, and industrial monitoring, where reliable power over extended periods can provide significant operational advantages.

Radioisotopes such as Sr-90 and Am-241 have potential applications in radioisotope power systems, subject to the technical requirements of specific power-conversion technologies. Access to reliable domestic isotope sources could help support future innovation in these fields while reducing dependence on constrained supply chains.

Curio’s NuCycle technology is designed to recover valuable materials from used nuclear fuel, including radioisotopes that could serve emerging commercial markets. By exploring potential collaboration with Curio, AtomiQ seeks to better understand future isotope availability, material qualification requirements, and opportunities to integrate recovered isotopes into its nuclear-voltaic technology development.

The collaboration is non-exclusive, and both companies remain free to pursue other research, commercial, and strategic opportunities. Any future supply or development arrangements will be established through separate agreements.
