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.

Modeling was carried out on vapor-liquid equilibria of nitric acid containing highly concentrated fission product nitrates to simulate the evaporation characteristics of a reprocessing plant high-level liquid waste (HLLW) concentrator. Results obtained with the model verified its reliability for prediction of vaporliquid equilibria of nitric acid containing highly concentrated nitrates. The results compared well with experimental data obtained with a pilot plant for HLLW concentration (capacity of 40 dm3).
