Lightbridge Commends U.S. Department of Energy’s Launch of UPRISE Initiative to Accelerate U.S. Nuclear Energy Expansion
Rhea-AI Summary
Lightbridge (Nasdaq: LTBR) praised the U.S. Department of Energy’s new UPRISE initiative, announced March 12, 2026, which targets 2.5 GW of additional nuclear capacity by 2027 and 5 GW by 2029 to expand U.S. nuclear output.
The DOE program includes supply-chain assessments, plant upgrades, and reactor restarts, and cites more than $289 billion in available loan authority with up to 80% financing for eligible projects. Lightbridge highlighted its fuel design and ongoing irradiation testing that began in November 2025 as positioning the company to support longer-term uprate goals.
Positive
- UPRISE targets 2.5 GW additional capacity by 2027
- UPRISE aims for 5 GW additional capacity by 2029
- DOE financing: more than $289 billion available, up to 80% project financing
- Lightbridge began irradiation testing in the Advanced Test Reactor in November 2025
Negative
- Initial UPRISE targets through 2027 rely on conventional uprate methods, not advanced fuel
- Lightbridge expects meaningful contribution primarily in the 2030s, delaying near-term commercial impact

24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Historically, LTBR’s moves have mostly aligned with news tone, with notable downside following equity-financed growth updates and stronger upside around visibility and technical milestones.
Over the last several months, Lightbridge has focused on strengthening its balance sheet and advancing its advanced fuel program. Earnings updates on Nov 5, 2025 and Feb 25, 2026 highlighted higher cash balances alongside wider losses. Technical milestones included starting irradiation testing at Idaho National Laboratory on Nov 19, 2025. Investor outreach via multiple conferences in early 2026 coincided with a double‑digit positive reaction. Today’s DOE‑related announcement fits into this narrative of policy tailwinds supporting a capital‑intensive, long‑dated development roadmap.

Lightbridge Fuel is Designed to Provide the Greatest Power Uprates to Existing Pressurized Water Reactors
RESTON, Va., March 16, 2026 (GLOBE NEWSWIRE) -- Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, today commended the U.S. Department of Energy’s (“DOE”) launch of the Utility Power Reactor Incremental Scaling Effort (“UPRISE”), a new initiative aimed at significantly expanding the nation’s nuclear energy capacity by maximizing the output of existing reactors, restarting dormant facilities, and extending reactor operating lifespans.
Announced on March 12, 2026, the UPRISE initiative targets 2.5 GW of additional nuclear capacity by 2027 and 5 GW of total additional capacity by 2029. The initiative directly advances the objectives of executive orders signed by President Trump in May 2025, which call for quadrupling U.S. nuclear generating capacity from approximately 100 GW to 400 GW by 2050 and directing DOE to facilitate 5 GW of nuclear power uprates at existing reactors.
UPRISE consists of a three-pronged approach: establishing the business case through supply chain and equipment assessments, facilitating physical plant upgrades requiring license amendments, and supporting reactor restarts. The DOE’s Office of Energy Dominance Financing has more than
Power uprates represent one of the most cost-effective pathways to expanding nuclear energy capacity in the United States. Historically, 171 approved uprates have added approximately 8.5 GW of electric capacity to the U.S. grid—the equivalent of roughly eight large reactors—at a fraction of the cost of new construction. The Nuclear Regulatory Commission currently anticipates approximately 30 additional uprate applications through 2030, representing roughly 2.5 GW of potential new capacity.
Lightbridge Fuel™ can play a meaningful role in supporting the goals of the UPRISE initiative. Lightbridge Fuel is being designed to provide the greatest power uprates to existing pressurized water reactors. Lightbridge Fuel’s proprietary helical multi-lobe design operates at approximately 1,000°C cooler than conventional nuclear fuel, significantly enhancing safety margins and reducing the risk of hydrogen generation during design basis events.
While DOE officials have indicated that initial UPRISE capacity targets through 2027 are based on conventional uprate methods, we believe advanced fuel technologies can contribute meaningfully to capacity expansion goals in the 2030s and beyond. Lightbridge’s ongoing irradiation testing of enriched uranium-zirconium alloy fuel material samples in the Advanced Test Reactor at Idaho National Laboratory, which commenced in November 2025, positions the Company to support this next phase of generating capacity expansion within the U.S. nuclear reactor fleet.
Seth Grae, President and Chief Executive Officer of Lightbridge, commented, “We commend the Department of Energy for launching the UPRISE initiative, which represents a decisive and practical step toward strengthening America’s energy security. Power uprates at existing reactors are among the fastest and most cost-effective ways to put more clean, reliable electricity on the grid—and they align directly with the President’s executive orders to expand our nation’s nuclear capacity. Lightbridge Fuel is being designed to deliver meaningful power uprates with enhanced safety margins, and we look forward to contributing to this important national effort as our fuel technology progresses through its development program and commercial deployment.”
