In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

On the basis of the simple formalism, numerical results for a set of hexagonal fast reactor lattices are presented. This allows the influence of lattice parameters on the diffusion coefficients and the sodium-voiding effect to be pointed out. Comparisons with calculations based on a cylindrical cell model are also given. They lead to the conclusion that the Wigner-Seitz approximation can underestimate the diffusion coefficients in fast lattices with larger gap widths.
