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 23Na(n,2n) reaction produces the radioactive product 22Na, with a half-life of 2.61 years. For sodium-containing systems this reaction can result in a radioactive contamination problem. Currently available experimental cross sections for this reaction are in strong conflict. Comprehensive nuclear model calculations performed as part of the sodium evaluation for ENDF/B-V are in agreement with one of the experimental data sets. Acceptance of this data set results in an (n,2n) cross section larger than was given in ENDF/B-IV by ∼37% at 15 MeV and by as much as a factor of 4 at 20 MeV.
