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 recycle value of the fuel discharged from light water reactors has been determined from the viewpoint of recycle in pressurized water reactors. It is concluded that no economic advantage can be gained unless both uranium and plutonium are recycled and only if the reprocessing cost remains below $366/kg. A value based on initial substitution method has also been calculated for plutonium having different concentrations of fissile and fertile isotopes. It has been estimated that under the self-generated recycle option, the neutronic worth of recycled plutonium is reduced to ∼70% of the worth of no-recycle plutonium in 3 to 4 recycles and decreases very slowly after that.
