New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

Neutron capture by a sample enriched in 41K and by a natural potassium sample (93.26% 39K) was measured at the Oak Ridge Electron Linear Accelerator as a function of neutron time of flight over a 40-m flight path. Resonance peaks were fitted by a least-squares fitting program to obtain Breit-Wigner resonance parameters. The energy range extended to all resonances below 153 keV. Corresponding average capture at a temperature typical of stars, kT = 30 keV, is calculated as (11.8 ± 0.4) mb for 39K and (22.0 ± 0.7) mb for 41K.
