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.

Cross sections have been measured for the 19F(n, p)19O and 19F(n, α)16N reactions from near threshold to 9 MeV. The 238U(n, f) reaction was used as a standard for determining neutron fluence, and a cyclic activation technique enabled measurements to be made on the short half-life activities of the reaction products. The results from this work are compared with corresponding data sets from the literature. These measurements support, qualitatively, the previously reported structure in the excitation functions for these reactions.
