Nuclear Energy shares rallied on Monday. Oklo rose nearly 25%; Lightbridge, NuScale Power rose around 19%; Centrus rose 6%.

Lightbridge touts three technical papers presented at the TopFuel 2024 Conference in Grenoble, France, which it said further validate the enhanced safety and performance of Lightbridge Fuel, particularly its improved performance under extreme conditions.

The company said a study by MIT which simulated the performance of Lightbridge Fuel in NuScale's small modular reactor confirms the fuel operates at significantly lower temperatures compared to traditional fuel, with improved safety margins that can enable power uprate opportunities while maintaining safe operations.

Structural Integrity Associates conducted a study evaluating Lightbridge Fuel in a pressurized water reactor under normal and accident conditions and concluded that Lightbridge's metallic fuel is safer than conventional UO2 fuel, particularly in accident conditions, the company said.

Lightbridge also presented an overview of some of the company's previous fuel development activities, including results from an experimental test, previously conducted in an overseas test reactor, where its metallic fuel rodlets endured ~24 hours in dryout conditions during irradiation.

The company said the studies confirmed the expected performance of Lightbridge Fuel and provided a basis for continued development and future regulatory licensing.
