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.

The neutron total cross sections of 181Ta and 238U have been obtained in the energy range from 24.3 keV to 1 MeV by means of neutron transmission measurements using the Japan Atomic Energy Research Institute Linac, The measurements were carried out with the iron-filtered neutron beam technique and the time-of-flight method, using an NE-110 plastic scintillator as a neutron detector at a 100-m station. For 238U, correction for the resonance self-shielding effect was taken into account below 270 keV by measuring the transmission of four samples of different thicknesses. By fitting average R matrix calculations to the observed total cross sections, the neutron strength functions Sℓ for p and d waves, and distant level parameters for s, p, and d waves were deduced to be: , and for 181Ta, and , and for 238U. The effective s-wave scattering radii were 7.90 ± 0.03 and 9.30 ± 0.04 fm for 181Ta and 238U, respectively.
