ASP Isotopes’ UK Subsidiary, Quantum Leap Energy Ltd., Enters Early Engagement Process with UK Nuclear Regulators

WASHINGTON, Nov. 05, 2025 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. (NASDAQ: ASPI) (“ASP Isotopes” or the “Company”), an advanced materials company focused on developing technologies and processes for the production of isotopes for multiple industries, today announced a regulatory progress update in its initiative to produce High-Assay Low Enriched Uranium (“HALEU”) in the United Kingdom. The Company’s UK subsidiary, Quantum Leap Energy Ltd (“QLE Ltd”), has formally commenced early engagement for regulatory pathways (“Early Engagement”) with the UK’s regulators on new nuclear projects.

Following successful completion of national security due diligence, the Department for Energy Security and Net Zero (“DESNZ”) confirmed QLE Ltd’s eligibility to enter Early Engagement with the Office for Nuclear Regulation (“ONR”), the regulator for the nuclear industry in the United Kingdom. HALEU is required to fuel most advanced modular reactor designs and this development sets ASP Isotopes’ subsidiary, Quantum Leap Energy, on the path to be the first commercial producer of HALEU in the UK.

Bill Eden, President of QLE Ltd, commented:

“By producing the HALEU required to fuel the next generation of advanced modular reactors, QLE Ltd will contribute directly to the UK’s clean power, energy security, and economic growth agendas. Our early engagement with ONR is a vital step in establishing the safety, security, and safeguarding standards that will underpin our responsible uranium enrichment in the UK.”

Next steps include continued engagement with the ONR and environmental regulators while QLE Ltd selects an optimal site for its UK operations. The company is also preparing its nuclear site licence and environmental permit applications and will work closely with DESNZ to obtain permission to enrich uranium for civil and commercial purposes. While definitive regulatory timelines have not yet been confirmed, internal estimates indicate a potential pathway to full licensing is achievable within this decade, subject to regulatory and site-specific progress.

In addition, Rich Deakin joined QLE Ltd this week as Senior Vice President and Managing Director, UK Strategic Projects. Rich brings more than 35 years of experience across civil and defence nuclear sectors in the USA, UK, and Japan. He has previously held senior roles at Rolls-Royce, NuScale Power, Sellafield Ltd, and most recently directed UK Research and Innovation’s Low-Cost Nuclear Challenge. He is also a director and trustee of the Nuclear Institute.

Rich Deakin, Senior Vice President and Managing Director UK Strategic Projects, commented:

“I am delighted to be joining QLE Ltd at this pivotal moment for both the company and the wider UK nuclear industry. Establishing a sovereign HALEU production capability is a strategic national objective, and QLE Ltd’s mission aligns perfectly with the UK’s ambition to deliver clean, secure, and competitive energy. I look forward to helping build the partnerships and technical capability that will enable QLE Ltd to play a leading role in the global HALEU supply chain.”

This initiative further reinforces ASP Isotopes’ global strategy to expand its enrichment capabilities across multiple regions and applications - from advanced nuclear fuels to next-generation materials - supporting the transition to cleaner and more secure energy systems worldwide.

About ASP Isotopes Inc.

ASP Isotopes Inc. is a development stage advanced materials company dedicated to the development of technology and processes to produce isotopes for use in multiple industries. The Company employs proprietary technology, the Aerodynamic Separation Process (“ASP technology”). The Company’s initial focus is on producing and commercializing highly enriched isotopes for the healthcare and technology industries. The Company also plans to enrich isotopes for the nuclear energy sector using Quantum Enrichment technology that the Company is developing. The Company has isotope enrichment facilities in Pretoria, South Africa, dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes).

There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing, and Molybdenum-100, Molybdenum-98, Zinc-68, Ytterbium-176, and Nickel-64 for new, emerging healthcare applications, as well as Chlorine-37, Lithium-6, and Uranium-235 for green energy applications. We believe the ASP technology (Aerodynamic Separation Process) is ideal for enriching low and heavy atomic mass molecules. For more information, please visit .
