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.

For each plane over which foil activation was integrated in the preceding article, the corresponding value was calculated by the DAEDALUS code with an assumed set of D-D, hydrogen, and oxygen cross sections. Account was taken of the foil angular sensitivity and the finite size of the source tube. The experimental and theoretical values agree well at individual planes and yield ages of 126 ± 1 cm2 and 129 ± 1 cm2 respectively. Since this slight discrepancy is opposite in direction to that for fission spectrum neutrons, one might suspect that it was caused by unjustifiably ignoring certain effects in the analysis; however, an account of most of these effects would increase the calculated age still further.
