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 RETRAN-02 analysis was performed for a loss-of-feedwater transient without scram for a Westinghouse four-loop plant with Series 51 steam generators. A goal of this study was to use the same plant parameters that were used by Westinghouse in a report issued in December 1979. The primary differences in results from the two studies can be attributed to differences in the two methodologies. Sensitivity of the primary pressure response to steam generator nodalization, turbine trip time, moderator reactivity feedback coefficients, and Doppler reactivity coefficients was also studied.
