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-section ratios for production of the 0.478-MeV gamma ray by the 7Li(n, n′γ)7Li reaction relative to fast-neutron fission of 235U have been measured from 0.57 to 4 MeV with an estimated error of ±8%. The measurements were made using a shielded Ge(Li) detector, a fission detector, and time-of-flight techniques. The measured ratios and ENDF/B-IV fission cross sections were used to compute cross sections for the 7Li(n, n′γ)7Li reaction. These values are compared with corresponding reported experimental values and with the ENDF/B-IV evaluation for this reaction. The available data tend to fall into two distinct groups that disagree by as much as 25% at some energies. The results of the present work are consistent with the group that favors smaller cross sections at most energies.
