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.

Interactions of neutrons with sodium have been studied by measuring gamma-ray-production cross sections. Spectra were obtained for incident mean neutron energies En = 4.85, 5.4, 5.9, 6.45, 7.0, and 7.5 MeV. Data were obtained at angles of 125 and 55 deg using Ge(Li) detectors. Time-of-flight was used to discriminate against pulses due to neutrons and background radiation.Absolute cross sections for production of gamma rays were obtained for the incident neutron energies quoted above. The data have been compared with previous inelastic neutron scattering results and evaluated cross sections, with good agreement. The spectra were studied for gamma rays which could be associated with deexcitation of nuclear levels having unknown decay modes. Gamma rays were found having energies appropriate for decay of levels at excitation energies Ex = 5762, 5934, 5967, 6115, 6576, and 6866 keV.
