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.

In this paper a new definition is given of the diffusion coefficient as a second-order tensor fully describing the anisotropic character of neutron diffusion in a homogeneous convex body. Numerical values for the diffusion coefficient tensor are reported for some typical geometries.
