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.

The tritium production cross section of 7Li was measured between 5 and 14 MeV by irradiating LiOH pellets with monoenergetic neutrons. The neutron fluence was determined using a calibrated NE-213 liquid scintillator and the tritium produced by β counting in a liquid scintillation spectrometer. The technique for determining the amount of tritium produced was confirmed by a measurement of the 6Li(n, t)α cross section at thermal energies using irradiations in the GLEEP reactor. The results for the 7Li(n,n′αt) cross section are ∼25% lower than the ENDF/B-IV values with a mean uncertainty of 6%. The results are close to a recent evaluation below 11 MeV, but are 23% lower at 14 MeV.
