BERKELEY, Calif., April 07, 2026 (GLOBE NEWSWIRE) -- Deep Isolation Nuclear, Inc. (“Deep Isolation” or the “Company”), a leading innovator in nuclear waste disposal technology, today announced that it will exhibit its full-size Universal Canister System (UCS) prototype at Booth 401 during the 2026 ARPA-E Energy Innovation Summit in San Diego, California, April 7–9. The Company will also participate in a technology demonstration showcase on Tuesday, April 7, highlighting how the UCS supports safe, scalable, and flexible disposal of spent nuclear fuel from advanced reactors.
The UCS, designed for storage, transportation, and disposal of nuclear waste across multiple waste forms, was recently featured at Deep Isolation’s groundbreaking event in Cameron, Texas, which marked the launch of the Company’s full-scale, at-depth demonstration program.
Developed through the DOE-funded Project UPWARDS, the UCS was engineered, fabricated, and rigorously tested over a three-year period to manage spent fuel and high-level waste from advanced reactors. Separately, Project SAVANT validated that the materials used in the UCS and borehole systems can resist corrosion and maintain structural performance under realistic deep borehole conditions. Together, these initiatives established integrated safety and performance criteria and produced the world’s first disposal-ready UCS prototype.

Attendees at Booth 401 will have the opportunity to view the full-size prototype and engage with Deep Isolation experts on the engineering, safety, and performance aspects of the UCS. The Deep Isolation team will also present the Universal Canister System and its deep borehole disposal technology on Tuesday, April 7 at 7:00 p.m. PDT during the technical demonstration session organized by ARPA-E.
“The UCS builds on our earlier canister designs to provide a single system capable of storing, transporting and disposing of waste from both advanced reactors and the existing nuclear fleet,” said Jesse Sloane, Executive Vice President of Engineering at Deep Isolation. “At the ARPA-E Summit, we’re showcasing our full-scale UCS prototype, which we plan to deploy as part of our at-depth demonstration program for deep borehole disposal.”
The ARPA-E Energy Innovation Summit brings together nearly 3,000 energy innovators, including leaders from industry, startups, academia, and government, to explore disruptive technologies in nuclear, AI, energy storage, and other advanced energy sectors.
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 99 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 radioactive waste from legacy and 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.
The foregoing is not an exhaustive list of all the factors that may cause any forward-looking statements to prove inaccurate or our actual results to differ materially from our expectations and forecasts.
