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.

An electrocatalyzed process has been described for the dissolution of plutonium from the contaminated neoprene gauntlets used during the fabrication of plutonium-bearing fuels. Agents Ag(II) and Ce(IV) were used as catalysts. The results indicated that it was possible to leach out plutonium satisfactorily from such contaminated neoprene gauntlets. The problems involved in processing with Ag(II) and the limitations of the process are also discussed. Further, plutonium was separated from the leached solution by solvent extraction using di-2-ethylhexyl phosphoric acid as the extractant.
