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.

The importance of waste categories other than high-activity waste in the context of long-term risk potential has been increasingly stressed over the last few years. Particular emphasis has been placed on the need for improved techniques for alpha waste reduction, conditioning, and disposal. One way to achieve this is based on an oxalate precipitation technique that recovers the actinides from all liquid alpha waste stream sources. As a result, a fully integrated alpha waste management is conceived that provides a rework unit for plutonium recovery, operating on line with reprocessing and with added incentives, such as savings in fissile material, reduced downtime, reduced medium level liquid waste volumes, and the possibility of confining neptunium and its precursors to a single stream.
