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.

By making public health and safety a primary criterion in the initial conceptual design, future nuclear power plants could be made inherently safe to the point where they could be legitimately sited nearly anywhere instead of only in the most remote locations. It is found that an unpressurized, “pool-type,” sodium-cooled reactor, which would be controlled by the movement of bottom entry fuel assemblies, would allow a heavy shielding dome to be permanently installed directly over the reactor. This would allow on-line refueling and the continuous removal of the free gaseous fission products from the reactor to a naturally cooled, well-protected site. It would also allow high-temperature decay heat to be transported directly to the ever present atmosphere by a system that is simple enough to preclude fuel melting in a shutdown reactor.
