LLNL, Ampera partner to develop thorium-based TRISO fuel
Lawrence Livermore National Laboratory has formed a strategic partnership with Ampera to develop the company’s nuclear fuel concept through a project named THUNDER, for Thorium Unimodal Droplet Ejection for Reactors.
The focus of THUNDER is fabricating TRISO made with kernels of thorium rather than the usual uranium. LLNL and Ampera will evaluate and optimize liquid metal–jetting technology to produce highly uniform, spherical kernels of thorium-232 for later processing into TRISO fuel.

Irradiated UO2 fuel elements with multiple and single 0.8-mm-diam artificial defects showed significant diametral increases, bowing, and sheath cracking after <200 h at 250°C in air. An irradiated UO2 element with a natural defect under identical conditions exhibited similar behavior. Fuel oxidation was localized in the vicinity of the defects; behavior was independent of power history.
