Lightbridge (Nasdaq: LTBR) announced on April 15, 2026 that the European Patent Office issued a Notice of Allowance for European Patent Application No. 22777419.7, titled “Multi-Zone Fuel Element”.
The allowance covers Lightbridge's multi-zone nuclear fuel element design and associated additive manufacturing methods across 39 contracting states, extending the company's U.S. and international patent portfolio and expanding IP protection for its advanced fuel architecture.
Lightbridge (Nasdaq: LTBR) announced that President and CEO Seth Grae will present at three investor conferences in April 2026: Jefferies Virtual Nuclear Conference (April 8, 8:45 a.m. ET), Gabelli Waste & Environmental Services Symposium (April 9, 2:00 p.m. ET, New York), and The Economist Nuclear Summit panel (April 15, 13:00 BST, London).
Registration and webcast access details are available through each conference organizer.
Lightbridge (Nasdaq: LTBR) received a Notice of Allowance from the USPTO for U.S. Patent Application No. 18/383,668 titled “Fuel Assembly” on April 1, 2026. The allowed 16 claims cover spirally twisted, multi-lobed metallic fuel elements and assemblies for pressurized heavy-water reactors, including CANDU designs, with a moderator-to-fuel ratio of 2.4 or less. The application is a divisional of earlier U.S. filings and extends a patent family that includes four issued U.S. patents.
Lightbridge (Nasdaq: LTBR) will serve on the Industry Advisory Board for a $6 million, four-year DOE-funded nuclear materials research project led by Penn State called BTN2M2.
The consortium will build a radiologically-dedicated dual-beam plasma Focused Ion Beam (FIB) and a Nuclear Materials Micro-Fabrication Facility to enable micro-scale study of radioactive materials, reducing sample radioactivity by up to 17 orders of magnitude and expanding research access. Lightbridge will advise research direction with an emphasis on irradiation behavior of cladding for Lightbridge Fuel.
Lightbridge (Nasdaq: LTBR) presented advanced fuel research at TMS2026 in San Diego on March 19, 2026. Two technical managers delivered talks on metal fuels and U-Zr alloy properties, highlighting a Lightbridge-validated framework that models the company's proprietary UZr2 fuel using measured coupon data.
The presentations were in the metal fuels session chaired by Professor Ericmoore Jossou, reinforcing Lightbridge's technical role in advanced nuclear fuel development.
Lightbridge (Nasdaq: LTBR) entered an initial engineering contract with Stern Laboratories to assess the thermal‑hydraulic (TH) performance of Lightbridge Fuel for light water reactors. The multi‑phase program includes electrically heated fuel simulator design, single‑ and nine‑rod CHF tests (600–2,200 psia), and a multi‑year testing program to support U.S. licensing. Phase 1 is estimated to take approximately one year to complete.
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.
