ASP Isotopes Inc. Completes Construction Phase of Ytterbium-176 Enrichment Facility

- The Company has completed the construction phase of the first Quantum Enrichment plant for Ytterbium-176, approximately nine months ahead of the original schedule.

- The Company expects to offer highly enriched Ytterbium-176 for commercial sale during 2025 after completion of the commissioning phase.

- The Company announces the hiring of Lt. Col. William (Bill) Eden, MBE, who will lead the Company’s nuclear fuel operations in the United Kingdom.

WASHINGTON, Sept. 03, 2024 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. NASDAQ: ASPI (“ASP Isotopes” or the “Company”), an advanced materials company dedicated to the development of technology and processes for the production of isotopes for use in multiple industries, today announced advances in its construction program and the hiring of key staff.

Ytterbium-176 Enrichment Facility

The Company’s Ytterbium-176 enrichment facility will be the Company’s third enrichment facility in South Africa and its first isotope enrichment facility to utilize Quantum Enrichment, a novel laser method of enrichment. The Company believes that this novel laser-based enrichment method promises affordability, lower production costs, and efficient construction, relative to other older generation methods of isotope enrichment. Construction of the Ytterbium-176 facility was originally planned to conclude during mid-2025; however, the team has managed to accelerate its construction timeline by approximately nine months.

Following a commissioning phase, this facility is expected to produce commercial quantities of highly enriched Ytterbium-176 for sale during 2025. Ytterbium-176 (176Yb) is a key stable isotope used in the production of Lutetium-177 (177Lu). Lutetium-177 is an emerging beta emitting radiopharmaceutical used in oncology drugs such as Novartis’ Pluvicto. There are currently two FDA approved drugs and more than 66 ongoing clinical trials for drugs that require Lutetium-177.

Consensus forecasts for Novartis’ Pluvicto exceed $4 billion and the beta emitting radiopharmaceutical market is expected to exceed $15 billion per annum in the next decade.(1) The supply chain for this radioisotope has been particularly challenged with recent industry reports highlighting over two months treatment delay due to lack of drug availability.(2) The Company believes that the only supplier of commercial quantities of Ytterbium-176 is Rosatom, the Russian state-owned entity. The Company is in discussions with multiple potential customers and aims to offer commercial supplies of Ytterbium-176 during 2025.

“Currently, there exist significant supply-side challenges for many essential radioisotopes used in various oncology treatments. We have received a considerable amount of interest from customers in North America, Europe and Asia for Ytterbium-176 and we look forward to easing supply chains and improving the quality of life of thousands of patients every year”, said Paul Mann, ASP Isotopes Inc.’s Chairman and CEO.

Global Leader of ASPI’s U.K. Nuclear Strategy

The Company has recruited Lt. Col. William (Bill) Eden, MBE to lead the Company’s U.K. nuclear strategy. Bill’s 27-year career in the U.K. Army has involved serving two tours in Afghanistan, as well as serving as the British Army’s strategic liaison officer at The Pentagon, U.S.A and as a planning officer at NATO. He is currently serving within Land Command in the U.K. and expects to retire from the U.K. Army during 4Q 2024. Prior to joining the U.K. Army, Bill graduated from Cambridge University with an M.A. (Cantab) in Natural Sciences. Lt. Col Eden is expected to assume his responsibilities during the fourth quarter 2024.

“Bill’s leadership skills, experience in managing operations, ‘complex projects and programmes, supply chains, logistics and security, as well as his experience of interacting with multiple governments and stake holders, makes him the ideal person to advance our nuclear strategy in the United Kingdom”, said Paul Mann, Chairman and CEO of QLE.

“Following a highly fulfilling and exciting career in His Majesty’s Armed Forces, I look forward to moving onto new challenges. The world is currently suffering from a great many supply chain issues that might prevent us from meeting 2050 climate goals. I look forward to helping solve some of these, improving energy security and assisting the U.K. in expanding its leadership position in nuclear energy”, said Lt. Col. Bill Eden.

The U.K. is one of many countries that have pledged to triple the amount of nuclear power by 2050. The U.K. has committed to deploy up to 24GW of nuclear power by 2050.(3) Basic nuclear fuels (e.g., low-enriched uranium) are currently supplied by a limited number of companies, and supply chains have been challenged for numerous years. Recent geopolitical events have highlighted the urgent need for additional investment into the nuclear fuel supply chain. For example, in May 2024, Russia’s state-owned uranium supplier, Tenex, notified its US customers of a potential force majeure event following a law recently signed by President Biden that bars imports of Russian nuclear fuel.

The Company is evaluating the potential opportunity to construct an advanced nuclear fuel plant in the United Kingdom, which would likely result in the inward investment of hundreds of millions of dollars from Quantum Leap Energy LLC and its partners and customers. The advanced nuclear fuel plant would likely create hundreds of permanent jobs in the United Kingdom. ASP Isotopes has previously announced that it has entered into two MOUs with U.S.-based Small Modular Reactor (SMR) companies that contemplate the SMR companies making capital investments into the development of high-assay low-enriched uranium (HALEU) enrichment facilities. Potential customers, with whom ASP Isotopes has been in discussions, have indicated their requirements of over $37 billion of HALEU by 2037.

We believe HALEU will be required for the nuclear fuel component for the new generation of nuclear reactors, such as SMRs (small modular reactors), that are now under development for commercial and government uses. Currently, there are no Western producers of HALEU in commercial quantities, and many SMR companies worldwide face substantial delays until this fuel supply issue is resolved. The Nuclear Energy Institute estimates that there may be a HALEU supply shortage of approximately 3,000 metric tons by 2035. (4) However, based on discussions with and the interest received from potential customers, the Company believes this figure may be significantly larger.
