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 using an idealized model, the reduction in potential radiation risks, as a function of increasing distance between nuclear power plant and load center, was compared to the corresponding increase in power transmission costs. Based on the U.S. Nuclear Regulatory Commission guideline of $1000/man-rem, remote siting was not found to be a cost-effective risk-reduction method. However, this guideline applies only to the biological risks of radiation exposure, explicitly excluding measures of the relevant social values. It is suggested that methodologies from many disciplines can be applied within the risk assessment framework to allow the inclusion of value measures in public decisions that regulate the integration of technological and social systems.
