Lightbridge announces first U-Zr fuel rod samples extruded at INL
Lightbridge Corporation announced today that it has reached “a critical milestone” in the development of its extruded solid fuel technology. Coupon samples using an alloy of zirconium and depleted uranium—not the high-assay low-enriched uranium (HALEU) that Lightbridge plans to use to manufacture its fuel for the commercial market—were extruded at Idaho National Laboratory’s Materials and Fuels Complex.

Numerical kinetic model of axial confinement is developed. Simulations show that in semi-collisional regime axial losses are determined by narrow “beam” of cold ions. Analytical treatment is proposed for the case of square-well magnetic field. Simulation of the ambipolar trapping of axial losses in the intermediate collision frequency range shows that essential suppression of axial losses is possible even when ambipolar barrier is of the order of ion temperature.
