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.

Theoretical development for the gamma-induced production of conduction band electrons in alumina is presented. Consideration of charge carrier mobility limited investigations to crystals having ionic bonding. Because of the difficulty in evaluating theoretical constants, all were combined and considered to be independent of temperature and radiation. This constant was evaluated experimentally. A model with a single trap depth was developed for predicting conductivity of ionic insulators as a function of temperature and radiation dose rate. The model is , where the first term on the right represents ionic conductivity of material external to a radiation field and the second term describes radiation-induced conductivity. Term P represents gamma dose rate in roentgen per hour, G is an experimentally determined constant, and W represents the energy necessary to raise trapped electrons into the conduction band. The temperature dependence of the mobility is represented by (T)3/2. Evaluation of experimental data for alumina gave W = 0.086 ± 0.014 eV and G = 7.4 × lO−21 (Ω−1cm−1K3/2R−1h).
