ASP Isotopes' subsidiary Quantum Leap Energy has signed a binding agreement with South Africa's state-owned Nuclear Energy Corporation (Necsa) to form a joint venture that will produce high-assay low-enriched uranium (HALEU) in South Africa.

What the joint venture covers

The venture will develop, finance, build and operate a test bench and a commercial-scale HALEU production facility at Necsa's Pelindaba site, according to World Nuclear News. Quantum Leap Energy holds 80% ownership of the joint venture.

The binding agreement follows a heads of agreement signed earlier in October 2026, moving the project from framework terms to a committed corporate structure.

TerraPower offtake secured

The venture is supported by off-take agreements with TerraPower, the U.S. developer behind the Natrium advanced reactor. TerraPower's Natrium project received its construction permit from the U.S. Nuclear Regulatory Commission on March 4, 2026, with the first plant targeted for commercial operation in 2030, subject to project schedule.

An offtake from a U.S. reactor developer is significant for a non-U.S. production project: it gives the South African venture a visible customer, and it gives TerraPower a potential supply source outside the small group of countries that can currently enrich to HALEU levels.

A new geography for HALEU

Russia has been the main commercial supplier of HALEU, and China also has large-scale production infrastructure. Since Russia's invasion of Ukraine in 2022, the United States, United Kingdom, Canada, Japan and the European Union have all pursued measures to reduce that dependency. Pelindaba would add a production route outside those established suppliers.

Realism is warranted. A test bench is not a commercial plant, and building, licensing and qualifying a HALEU facility takes years. A centrifuge cascade designed for HALEU must satisfy safety and non-proliferation requirements distinct from those for conventional enrichment, which lengthens authorization procedures independently of an operator's technical capability. Installations able to enrich uranium to these levels have been subject to very strict regulation since the 1970s, and administrative time adds mechanically to construction time.

Still, the combination of a binding joint venture, majority private ownership and a U.S. offtake customer makes this one of the more concrete additions to global HALEU capacity announced this year.
