<p>Winnipeg, Manitoba--(Newsfile Corp. - April 23, 2026) - Frontier Nuclear and Minerals Inc., d/b/a Frontier Nuclear (NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/FNUC">FNUC</a>)<b> ("Frontier")</b>, a nuclear fuel cycle company, is developing capabilities in the uranium mining, enrichment and reactor sectors of the nuclear fuel cycle.</p><p>Today, Frontier announces that its  portfolio company, Kadmos Energy Services LLC ("<b>Kadmos</b>"), is preparing to initiate its dual experimental validation program at its engineering facility in Idaho Falls - marking a key step in advancing its SMR design forward toward licensing, commercial deployment, and downstream value creation.</p><p><b>Frontier CEO Remarks</b></p><p>"Kadmos represents Frontier's strategic expansion into small modular reactor deployment" said Frank Wheatley, CEO of Frontier.  "With the increasing global demand for nuclear power, Kadmos is building Frontier's capabilities in the SMR sector of the nuclear fuel cycle, and this milestone marks a critical step in converting that strategy into a licensable, commercial, and deployable asset."</p><p><b>Kadmos Engineering Validation Program</b></p><p>Kadmos has established its engineering facility in Idaho Falls to leverage proximity to Idaho National Laboratory, enabling direct access to a deeply specialized nuclear engineering workforce.  Kadmos' facility is equipped to initiate experimental verification and validation of its thermal-hydraulic models for its SMR design.  The data from this program will support SMR design development and regulatory qualification submissions, marking the transition from analytical design to hardware-back validation, a critical step in de-risking the SMR design and advancing toward regulatory licensing.</p><p><b>Kadmos SMR Design Strategy</b></p><p>Kadmos is advancing a light water reactor ("<b>LWR</b>") to materially reduce licensing risk and time-to-market, leveraging decades of operating data already available to the U.S. Nuclear Regulatory Commission ("<b>NRC</b>").  The NRC's newly finalized Part 53 framework reflects a meaningful step toward technology-inclusive licensing, with substantial weight placed on vendors demonstrating safety performance through operational data.  For novel reactor technologies, this creates a structural challenge because the data required to license a reactor can, in practice, only be generated by building and operating one.  Decades of global LWR operational experience provide a deep evidentiary base that Kadmos can directly draw from to accelerate its development roadmap, and avoid over-investment in testing capabilities.</p><p><b>Kadmos Commercial Strategy</b></p><p>Kadmos is developing its SMR technology to address the demand for data centers, industrial energy users, and defense-related applications requiring secure, reliable and scalable power.  Kadmos is advancing engineering, testing, and licensing activities in parallel, with initial commercial operations targeted for the early 2030's.</p><p><b>Kadmos CEO Remarks</b></p><p>"Idaho Falls gives us the talent base and the institutional relationships we need to execute our strategy," said Dr. Youssef Ballout, Kadmos Founder and CEO.  "Initiating experimental validation is a meaningful step forward.  We are focused on delivering a deployable, capital-efficient reactor for customers that need reliable power on a near-term timeline."</p><p><b>About Kadmos Energy Services</b></p><p>Kadmos Energy Services LLC is a U.S. based nuclear energy company focused on the development and deployment of small modular reactors using proven light-water reactor technology.  Kadmos' approach emphasizes low technological risk, established supply chains, and an execution driven model to enable accelerated licensing and near-term deployment.
