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.

Electron-photon cascade calculations and photoneutron-production calculations have been carried out for 150-MeV electrons on thick targets of Be and Ta. In the energy region of the giant resonance an evaporation model was used to calculate the production spectrum, and at higher energies (25 MeV) an intranuclear-cascade model was used. The calculated photoneutron-production spectra cover the energy range 0.01 to ∼100 MeV and are given for target thicknesses of 1 and 20 radiation lengths in both Ta and Be. A method is described and sufficient information is given so that estimates of the photoneutron-production spectra in targets of intermediate thicknesses may be obtained. Results on the photoproton-production spectra are also given. The spectra from the Ta and Be targets are compared and are found to have very different characteristics in that the number of low-energy (< 1 MeV) neutrons produced in the Ta target is much greater than that produced in the Be target and the number of high-energy ( a few MeV) neutrons produced in the Be target is larger than that produced in the Ta target.
