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 extended application of the FAPMAN planning model has been made to typical boiling water reactor (BWR) fuel loading and generation planning problems. The additional constraint on reactive fuel loading pertinent to BWRs was implemented, together with some improvements on the back-end fuel cycle economic model and the gradient projection method of searching for better generation plans. The flexibility of the FAPMAN planning tool has been demonstrated in numerical studies made in several degrees of optimization, for disposal or reprocessing options in the back end of the fuel cycle and for the bounded or free refueling cycle length.
