Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

We study the interaction of fusion-born particles and neutral beams (NBs) with field-reversed configuration (FRC) plasmas. The power deposited and the current generated are calculated for FRC reactors operating with the D-T and D-3He fusion reactions. In the beam studies we specify the beam energy and current, the injection point, and the impact parameter and include an ionization package to determine the position and velocity of the beam particles when they become ionized. In the case of fusion-born particles, we consider a large number of isotropic particle sources distributed inside the FRC. The plasma equilibria are obtained by solving the Grad-Shafranov equation with a pressure that contains linear and quadratic terms in the flux function. A Monte Carlo code that includes particle drag and diffusion is then employed to follow the exact trajectories of the fusion or beam particles and calculate the resulting current and deposited power. The effect of a rotating magnetic field and a toroidal field on the current and deposited power is also studied. In D-T reactors the current generated by the alpha particles is small, but the deposited power fraction is large, and NBs can produce significant currents with reasonable input powers. In D-3He reactors the fusion protons can produce large currents, but the deposited power fraction and the NB current drive efficiencies are low. A small toroidal field, compatible with high FRCs, reduces the deposited power fraction and the current.
