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.

Two discrete ordinates methods, the Sn and streaming ray methods, are applied to electron transport problems. Calculational results in the form of energy deposition profiles are compared with those obtained by the method of moments for the case of a 200-keV plane perpendicular source embedded in infinite aluminum. In a second set of calculations, Sn and streaming ray flux data are compared with results of a recently developed analytical benchmark technique applied to the solution of the energy-independent form of the Spencer-Lewis equation for electron transport. Satisfactory agreement with moments and analytical benchmark calculations is found. Areas of divergence among the various calculational methods are examined.
