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.

Measurements of the spectra of delayed neutrons from the thermal fission of 235U are reported over the energy range 30 to 1500 keV. The resolution is sufficient to identify locations of peaks in the spectra. Spectra for three different count-irradiation cycles are reported with the shortest representing a near equilibrium spectrum for delayed neutrons from 235U. Comparisons with existing data show relatively good agreement to the spectral peaks. A correction for the shield of the detector is introduced and applied to the current and previous work with reasonable results. In general, the new spectra are softer than previously reported and show more detailed structure.
