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 partial 2200-m/sec equivalent neutron capture cross sections (σ2200) and neutron capture resonance integrals (Ic) of 432.7-yr 241 Am to produce 152-yr 242mAm and 16.01-h 242gAm were measured relative to 59Co standards. The number of 242mAm atoms produced per 241 Am target atom was determined by high precision mass spectrometry after chemical purification of americium. The number of 242gAm atoms produced per 241Am target atom was determined by measuring the alpha activity of its 164.4-day 242 Cm daughter. The measured values for 241 Am are as follows: σ2200 (to 242mAm) = 83.8 ± 2.6 b, Ic (to 242mAm) = 208 ± 18 b (0.369-eV cutoff), σ2200 (to 242gAm) = 748 ± 20 b, and Ic(to 242gAm) = 1330 ± 117 b (0.369-eV cutoff). Measured values are compared with those calculated from the ENDF/B-III neutron cross-section library.
