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.

In the separation nozzle process, the enrichment of 235U is achieved by extremely high centrifugal forces in a curved flow of UF6 diluted by a light gas. Remarkable progress has been made in the economy of the process by bringing up the gas pressure and by introducing a nozzle system with double deflection of the jet. While the specific energy consumption is comparable to that of the American diffusion plants, the separation effect per stage is considerably higher than that of the classical technology. Therefore an economical application is possible for smaller and correspondingly cheaper plants. The process finds its first commercial application within the framework of German/Brazilian Cooperation. A so-called First Cascade consisting of 24 separation nozzle stages is under construction in Brazil. The development of components for commercial separation nozzle plants is well under way.
