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.

Information from the Evaluated Nuclear Data File (ENDF/B) has been used to construct energy-exchange kernels describing the energy transfer probabilities between neutrons and material lattice atoms. The kernels correctly incorporate all the available information on elastic scattering and inelastic scattering contained in ENDF/B. Their use removes much of the uncertainty in the calculation of primary-recoil spectra. Primary-recoil atom spectra for several elements in different reactor spectra have been generated. The influence of inelastic scattering on the recoil spectra is discussed. Results obtained with the ENDF/B data are compared with previously published information.
