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.

A toroidal field coil for a small aspect ratio, high field tokamak Ignition Test Reactor was designed based on compound constant tension coil shapes. Finite element analyses revealed the existence of bending stresses in this coil due to incompatible deformations of the different constant tension shapes at their common joining points. To correct this situation, the deformation equations of constant tension coils were derived and solved analytically. This permitted selection of cross-sectional dimensions for each coil segment that gave compatible deformations and no bending moments at the joining points. Zero moment theory for compound coils was then extended considering nonuniform continuous elastic coil support effects in the governing equations. Analytical and numerical results were obtained for this case as well.
