Lightbridge Joins White House UPRISE Initiative to Boost U.S. Nuclear Capacity

  • Lightbridge participated in the White House launch of UPRISE, a federal initiative to add 5 GW of nuclear capacity by uprating existing reactors.
  • Seth Grae, Lightbridge CEO, represented the company at the event held on June 17, 2026.
  • Lightbridge Fuel is designed to deliver significant power uprates for pressurized water reactors, aligning with UPRISE objectives.
  • The initiative supports the President’s May 2025 executive orders directing the DOE to facilitate 5 GW of power uprates.

The UPRISE initiative reflects a strategic shift toward maximizing output from existing nuclear infrastructure, aligning with broader U.S. energy security and decarbonization goals. Lightbridge’s participation underscores the growing emphasis on advanced nuclear fuel technologies to enhance reactor efficiency and grid stability. The initiative’s success could set a precedent for similar efforts globally, particularly in regions with aging nuclear fleets.
