Recent Breakthrough in Necsa HALEU Partnership with ASP Isotopes

On February 20, 2026, Quantum Leap Energy South Africa (Pty) Ltd, a subsidiary of Quantum Leap Energy LLC under ASP Isotopes Inc., signed a pivotal Pre-Implementation Services Contract with the South African Nuclear Energy Corporation (Necsa). This agreement marks a significant progression from their initial Memorandum of Understanding (MOU) in November 2024, propelling the Necsa HALEU nuclear research partnership toward practical implementation.

The collaboration focuses on siting, designing, constructing, commissioning, and operating a High Assay Low Enriched Uranium (HALEU) enrichment facility at Necsa's Pelindaba site near Pretoria. Necsa will supply essential facilities, infrastructure, utilities, and services, while a Joint Coordination Committee—comprising representatives from both parties—will oversee progress. This step addresses critical gaps in the global supply of advanced nuclear fuels essential for next-generation reactors.

Ryno Pretorius, CEO of Quantum Leap Energy, emphasized the shift from planning to action: "Gaining access to this internationally-recognized facility is intended to help us move from planning to implementation." Necsa Group CEO Loyiso Tyabashe highlighted the synergy: "Necsa intends to optimize global networks of over 60 years and complementary capabilities on enrichment with QLE."

This development not only revitalizes South Africa's nuclear capabilities but also opens avenues for research collaboration, potentially benefiting higher education institutions involved in nuclear engineering programs.

Understanding HALEU: The Fuel Powering Advanced Nuclear Reactors

High Assay Low Enriched Uranium (HALEU) refers to uranium enriched to between 5% and 20% uranium-235 (U-235), surpassing traditional low-enriched uranium (LEU) at up to 5% but remaining far below weapons-grade levels above 90%. HALEU enables more efficient, compact designs in small modular reactors (SMRs) and Generation IV reactors, offering higher burn-up, longer fuel cycles, and enhanced safety features.

The production process begins with uranium ore mining and milling to produce yellowcake (U3O8), followed by conversion to uranium hexafluoride (UF6) gas. Enrichment then separates U-235 from U-238 using methods like centrifugation, gaseous diffusion, or emerging laser-based techniques. Finally, the enriched UF6 is converted to uranium dioxide (UO2) pellets for fuel rods. ASP Isotopes' quantum enrichment (QE) technology promises lower energy use and scalability for HALEU.

Globally, HALEU shortages hinder SMR deployment. The US Department of Energy projects demand rising from 50 metric tons annually by 2035 to 500 tons by 2050, driven by AI data centers and decarbonization. South Africa's involvement positions it as a key player in diversifying supply chains.

Necsa's Legacy at Pelindaba: Hub of South African Nuclear Research

Necsa, established in 1999 under the Nuclear Energy Act, is South Africa's premier nuclear research and technology entity. Its Pelindaba facility, 33 km west of Pretoria, hosts the SAFARI-1 research reactor, a cornerstone for medical isotope production supplying over 20% of global molybdenum-99 (Mo-99) needs. Pelindaba also features particle accelerators, hot cells, and manufacturing for nuclear components.

Necsa's mandate spans research, development, and commercialization across the nuclear value chain, from fuel fabrication to waste management. Recent MOUs with CSIR for R&D and EWSETA for skills training underscore its innovation drive. The HALEU partnership aligns with Necsa's strategy to re-establish fuel production capabilities dormant since the 1990s uranium enrichment program.

Pelindaba's secure, regulated environment—overseen by the National Nuclear Regulator (NNR)—makes it ideal for sensitive enrichment activities. For researchers, it offers hands-on opportunities in reactor operations, isotope separation, and materials testing.

ASP Isotopes and Quantum Leap Energy: Pioneering Enrichment Innovation

ASP Isotopes Inc. (NASDAQ: ASPI), headquartered in the US with facilities in Pretoria, specializes in isotope enrichment using Aerodynamic Separation Process (ASP) for low atomic mass elements and developing QE for nuclear isotopes. QE employs laser excitation to selectively ionize U-235, enabling precise, efficient enrichment.

Quantum Leap Energy (QLE), ASPI's nuclear fuels arm, targets the full fuel cycle: conversion, enrichment (HALEU/LEU), lithium separation for fusion, and waste processing. Partnerships with TerraPower (Bill Gates-backed) and Fermi America bolster its HALEU ambitions, including a planned US facility. The Necsa deal leverages SA roots—ASP tech traces to 1980s local programs—for global scale.

From MOU to Pre-Implementation: Timeline of the Necsa HALEU Partnership

• Nov 2024: ASP Isotopes SA subsidiary and Necsa sign MOU for HALEU R&D and facility at Pelindaba.
• 2025: Discussions advance; ASP secures TerraPower supply deal, eyeing Pelindaba build.
• Feb 2026: QLE SA-Necsa Services Contract; Joint Committee formed.
• Next: Regulatory approvals (NNR), design/construction, R&D trials targeting market readiness by late 2020s.

This phased approach mitigates risks, building on three years of talks.

Boosting South Africa's Nuclear Research Ecosystem

South Africa's nuclear sector employs over 7,000, with Koeberg generating 5% of electricity. The HALEU project supports IRP 2019 goals for new nuclear capacity, including SMRs. Necsa's revival could create 500+ jobs in engineering, R&D, and operations.Explore research jobs in nuclear fields.

It enhances energy security amid load-shedding, leveraging SA's uranium reserves (6% global). Research outputs may include new materials, safety protocols, fueling publications and patents.

Links to Higher Education: Training the Next Nuclear Generation

Necsa partners with universities like North-West University (NWU), hosting SA's sole Nuclear Engineering Research Chair, and University of Pretoria (UP) via Bakeng se Afrika for radiation sciences. Programs cover reactor physics, materials, safety—essential for HALEU.

The partnership promises internships, theses on enrichment tech, and IAEA-backed training. EWSETA-Necsa MOU targets artisan skills; expect PhD/postdoc opportunities.View university jobs in SA.

This aligns with SA's nuclear human capital push, training 1,000+ scientists yearly.

Global HALEU Landscape and South Africa's Strategic Role

HALEU supply is bottlenecked; Russia dominates, US builds capacity (Centrus), but needs allies. SA's non-proliferation record, uranium, and Necsa expertise make it attractive. ASP's multi-site plans (SA, US, UK) diversify chains.

Benefits: Export revenues, tech transfer. Risks: Proliferation concerns, costs ($billions initial).

Challenges, Regulations, and Safety in HALEU Development

Key hurdles: NNR licensing, IAEA safeguards, capital (~$500M+ facility). QE tech validation needed. SA's history (Y-plant dismantled 1990s) demands rigorous safety.

• Safety: Multi-barrier UF6 handling, seismic designs at Pelindaba.
• Environment: Minimal waste vs. centrifuges.
• Economics: HALEU at $10,000+/kg initially.

Necsa's expertise ensures compliance.

Future Outlook: Jobs, Innovation, and Energy Independence

By 2030, facility could produce 20-50t HALEU/year, supplying SMRs locally/globally. R&D yields spin-offs: Medical isotopes, fusion lithium.
