Lightbridge Advances Nuclear Fuel Testing with Idaho National Lab Access
Event summary
- Lightbridge secures access to Idaho National Laboratory's Advanced Test Reactor Loop Facility for irradiation testing of its clad Lightbridge Fuel™ rodlets.
- Testing will simulate commercial reactor conditions, providing critical data for regulatory approval and utility adoption.
- Project scope includes experiment design, irradiation, and data collection over approximately 60 months.
- Fuel rodlets will be tested in both cylindrical and multi-lobe geometries, fabricated from enriched uranium-zirconium alloy.
- Data from this testing will benchmark Lightbridge's models and inform further testing in INL’s Transient Reactor Test Facility (TREAT).
The big picture
Lightbridge's access to the Advanced Test Reactor Loop Facility marks a critical step in the commercialization of its nuclear fuel technology. The ability to test under conditions mimicking commercial reactors is essential for gaining regulatory approval and securing utility contracts. This development comes as the nuclear industry seeks advanced fuels to enhance reactor safety, economics, and proliferation resistance, aligning with broader trends toward zero-emission energy solutions.
