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.

Neutron total and scattering cross sections of 238U have been interpreted in terms of a local, energy-dependent spherical optical potential with spin orbit coupling. Total cross sections to 10.0 MeV and scattering cross sections to 1.5 MeV, at 2.0 MeV and at 7.0 MeV were calculated and compared with reported experimental results and with values measured explicitly for support of these calculations. The statistical model was used in calculating elastic and inelastic scattering processes, and capture and fission reactions were taken into account. The effects of resonance width fluctuations and correlations and of deformation were examined. Satisfactory agreement was achieved between calculation and experiment.
