Lightbridge Fuel™ is Designed to Deliver Power Uprates that Expand the Output from Both the Existing U.S. Reactor Fleet and New Reactors
RESTON, Va., June 18, 2026 (GLOBE NEWSWIRE) -- Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, today participated in the White House launch of the Utility Power Reactor Incremental Scaling Effort (“UPRISE”), a federal initiative to expand U.S. nuclear capacity by maximizing output from the existing reactor fleet. The Company was represented by Chairman and Chief Executive Officer Seth Grae at the event held at the Eisenhower Executive Office Building in the White House complex in Washington, D.C.

UPRISE, launched by the U.S. Department of Energy (“DOE”), targets the addition of approximately 5 GW of nuclear capacity and advances the President’s May 2025 executive orders, which direct DOE to facilitate 5 GW of power uprates at existing reactors. The initiative brings together nuclear utilities, energy off-takers, and other stakeholders to support the expansion of output from the nation’s operating reactor fleet.
Lightbridge Fuel is being designed to deliver among the largest power uprates available to the operating pressurized water reactor (“PWR”) fleet, positioning the technology to directly contribute to UPRISE's objectives. The Company continues to advance Lightbridge Fuel through testing and qualification toward commercial deployment.
“UPRISE recognizes a straightforward reality: the fastest and most cost-effective megawatts we can add to the grid are the ones we draw from reactors already operating today,” said Seth Grae, Chairman and Chief Executive Officer of Lightbridge. “Lightbridge Fuel is being designed to deliver the greatest power uprates available to the existing pressurized water reactor fleet, and we were proud to take part in the launch of an initiative aimed squarely at that opportunity.”
“We are grateful to the Administration and the Department of Energy for convening this event,” Mr. Grae added. “We are advancing our fuel toward delivering additional clean, secure power.”
