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 activation measurements are reported for 44 reactions from 14 materials irradiated in a well-characterized neutron field produced by 40-MeV deuterons impinging on 9Be at the Oak Ridge Isochronous Cyclotron. Foil packets were located at 0 and 15 deg to the beam at 7.62 cm from the source, and additional foil materials were located directly on the deuteron beam stop 6.25 mm from the source. Integral tests were made for 30 reactions using previously measured time-of-flight (TOF) spectra and neutron cross sections, primarily from ENDF/B-IV, extrapolated to 44 MeV. The integral results are excellent, with an overall standard deviation of ±11% for 25 recommended reactions (±14% for 30 reactions), and neutron spectra unfolded with the SAND II code show excellent agreement with TOF measurements.
