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.

Cross sections and spectra for (n,xp) and (n,xα) reactions on 58Ni and 60Ni at energies of 9.4 and 11 MeV and for 58Ni at 8 MeV have been measured. This energy range spans the threshold for the (n,n’p) reaction. Based on comparison of Hauser-Feshbach calculations with the measured spectra, this reaction provides a large fraction of the proton spectrum at 11 MeV for 58Ni. Both (n,xp) and (n,xα) processes appear to be due largely to compound nuclear processes. Comparison of the measurements obtained here and those previously published at 15 MeV with calculations allows us to infer information about the nuclear level densities. Cross sections for (n,d) reactions are sufficiently small that only upper limits can be derived for them.
