Deep Isolation Launches Full-Scale Demonstration Program for Nuclear Waste Disposal

Groundbreaking Event officially kicks off deep borehole demonstration program, the first full-scale, at depth test of technology for safely and permanently disposing of nuclear waste deep underground

CAMERON, Texas, Feb. 02, 2026 (GLOBE NEWSWIRE) -- Deep Isolation Nuclear, Inc. (“Deep Isolation”), a leading innovator in nuclear waste disposal technology, today announced the launch of its multi-year, full-scale, at-depth deep borehole demonstration program (the “Demonstration Program”), in collaboration with the Deep Borehole Demonstration Center (“DBDC”), Halliburton (NYSE: HAL), Amentum (NYSE: AMTM), NAC International, and Occlusion Nuclear Solutions, to conduct testing of its deep borehole technology for safely and permanently disposing of nuclear waste.

Deep Isolation, in collaboration with Halliburton and the DBDC, hosted a Groundbreaking Event to officially launch the Demonstration Program on January 28, 2026. The event, held at the Deep Borehole Demonstration Center facility, located at the Halliburton Drilling Technology Facility near Cameron, Texas, brought together project partners and key stakeholders from across the nuclear industry, the U.S. Department of Energy, and officials from the State of Texas, Milam County, and City of Cameron.

The Groundbreaking Event marked the beginning of this critical demonstration project, which is aimed at building stakeholder and regulatory confidence in the Company’s deep borehole disposal technology. The Demonstration Program, which does not utilize radioactive material, will provide crucial data and operational experience to further the commercialization strategy for Deep Isolation’s deep borehole disposal technology.

“The groundbreaking marks the start of a historic program that will allow us to advance on the path to the commercialization of our deep borehole disposal technology and Universal Canister System,” said Rod Baltzer, Deep Isolation’s President and CEO. “We are thrilled to have brought together this extensive collaboration of leading organizations in nuclear technology, drilling services, and waste management to address one of the nuclear industry's most pressing challenges: developing a safe and permanent solution for nuclear waste disposal. We believe our technology, once commercialized, has the potential to revolutionize the nuclear industry with a long-term solution for disposing of spent nuclear fuel.”

“We value our collaboration with Deep Isolation on this important initiative,” said Duane Sherritt, vice president of Low Carbon Solutions for Halliburton. “Together with Deep Isolation and other collaborators, we will show how directional drilling plays a critical role in delivering subsurface storage locations.”

Deep Isolation’s nuclear waste disposal technology is being designed to leverage directional drilling to isolate spent nuclear fuel and high-level radioactive waste in deep boreholes located underground in suitable rock formations. Deep Isolation believes that directional borehole disposal could provide robust and deep isolation for many types of radioactive waste, provide flexibility in repository siting, as well as allow for modular implementation adaptable to specific waste management programs and inventories.

Deep Isolation’s Universal Canister System will be utilized in the Demonstration Program, has been extensively tested, and is engineered to contain various types of spent fuel and high-level radioactive waste from legacy and advanced reactors for long-term storage, transportation, and disposal.

About Deep Isolation

Deep Isolation is the first company to undertake development of technologies for nuclear waste disposal in deep boreholes. When commercialized Deep Isolation’s solution will offer a uniquely tailored solution to help countries identify, plan for and complete the necessary steps to dispose of their nuclear waste inventories. With 91 patents issued to date, Deep Isolation’s technology is being designed to leverage proven drilling practices to allow safe isolation of waste deep underground in horizontal, vertical, or slanted borehole repositories. Deep Isolation’s Universal Canister System was developed through a three-year project funded by the U.S. Department of Energy’s Advanced Research Projects Agency—Energy and is engineered to support integrated management of spent fuel and high-level waste from advanced reactors across storage, transportation and eventual disposal.

Forward-Looking Statements

Statements contained in this news release that are not historical facts are “forward-looking information” or “forward-looking statements” (collectively, “forward-looking statements”) within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include, but are not limited to, statements regarding our plans, objectives and expectations for our business, the future growth of our business and the nuclear energy and nuclear waste disposal industries as a whole, and future benefits expected to arise from our strategic partnerships. In certain cases, forward-looking statements can be identified by the use of words and phrases or variations of words and phrases or statements such as “may,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “will,” “could,” “project,” “target,” “potential,” “continue” and similar expressions. Forward-looking statements are based on management’s belief and assumptions, including current expectations and projections about future events and trends, and on information currently available to management.

Forward-looking statements in this or any other news release are subject to a number of risks, uncertainties, and assumptions that could cause actual results to be materially different from those expressed or implied by such forward-looking statements. Such risks, uncertainties, and assumptions are subject to a number of factors, including, among others: the failure of a market to develop for our deep borehole disposal solutions as quickly as we expect or at all; a failure of demand for our solution to develop sufficiently; regulatory and legal developments, including issues relating to obtaining regulatory approvals or permissions on the timelines we expect or at all; our lack of profitability; delays or failure in our initiative to complete a full-scale, at-depth demonstration of our Universal Canister System and our deep borehole solution; our failure to enter into contracts with customers or, once we do enter into contracts, to continue such contractual relationships or to receive new contract awards; our dependency on governmental contracts and awards; our  failure to manage our growth effectively or to execute our business plan; a failure to sustain and expand relationships with governmental entities and strategic partners; failure in the assumptions or analyses we have used in supporting forecasts or plans; our inability to commercialize our products at scale; the development or deployment of other technologies or solutions supplanting or competing with our technologies; challenges to our intellectual property; failures to protect, maintain, enforce, and enhance our intellectual property, and claims by others of intellectual property infringement; political and public perceptions of nuclear energy, including perceptions as to accidents or other high-profile events involving nuclear power facilities or radioactive materials; our liquidity and ability to raise capital; any inability to control operating and project costs and project delays or other project-related problems; security (including cybersecurity) breaches or disruptions; geopolitical, macroeconomic, domestic events or crises, including supply chain disruptions and other risks and uncertainties outside of our control; weather and effects of climate change; and litigation or legal proceedings that may be brought against us.
