Lightbridge Fuel Samples Complete Irradiation at INL
AI Summary
Lightbridge Corporation announced that the first batch of its fuel material samples successfully completed irradiation at the Idaho National Laboratory's (INL) Advanced Test Reactor (ATR). The samples were removed on May 6, 2026, and will undergo a cooling period before post-irradiation examination (PIE) begins later this year. This milestone validates the innovation behind Lightbridge Fuel, with data from the PIE expected to support ongoing fuel performance modeling and regulatory licensing for commercial deployment.
