The company says this is a critical step in the development of Lightbridge Fuel, a proprietary next-generation nuclear fuel technology for existing light water reactors and pressurised heavy water reactors which the company says can significantly enhance reactor safety, economics, as well as proliferation resistance.

The enriched uranium-zirconium alloy coupon samples were fabricated using the company’s proprietary method, which has previously been demonstrated at the Idaho National Laboratory (INL) using depleted uranium samples with zirconium-alloy cladding.

The enriched coupon samples are to undergo irradiation testing at INL’s Advanced Test Reactor, under an existing Cooperative Research and Development Agreement between Lightbridge and the lab. The irradiation testing programme and post-irradiation examination activities aim to generate critical irradiation performance data which will support the company’s regulatory licensing and commercialisation efforts for deployment of Lightbridge Fuel.

Lightbridge Fuel is also being developed for small modular reactors.
