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.

Activation measurements in fast neutron spectra, using detector foils in which the neutron mean-free-path in a resonance is small compared to the foil thickness, are revised by detailed space and energy self-shielding corrections. The experimental data are then comparable with the reaction rate density calculations. The self-shielding factors of individual Doppler-broadened resonances have been calculated with the integral transport theory. A multiple collision technique was required to treat resonance scattering inside the foil because of the small mean-free-path. The foil correction factor at each experimental position is obtained by combining the self-shielding factors of individual resonances with the calculated multigroup reaction rates at the foil locations. This gives a space-dependent foil correction factor for regions with spatially varying spectra. Applications of the foil correction technique to the integral reaction rate measurements of 197Au, 55Mn, 186W, and 232Th in a fast reactor blanket mockup are presented.
