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 series of simple laboratory experiments was conducted to test the feasibility of separation of plutonium-contaminated soil into plutonium-rich and depleted fractions. The purpose of the separation is to reduce the costs of managing plutonium-contaminated soil by separating a large fraction of the soil that can be disposed of as noncontaminated soil. Water-scrubbing (agitation) and washing of a sample of soil from the Savannah River Plant burial ground separated out a clay-silt fraction containing ∼95% of the plutonium, but comprising only one-third of the total soil; the remaining two-thirds of the soil was a sand that contained only ∼5% of the total plutonium. The technique appears to be adaptable to commercial sand scrubbing and classifying equipment, and should be generally applicable to soils of high quartz sand content such as the clayey sands typical of the coastal plain of the southeastern United States, but verification with other soils will require similar laboratory tests.
