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.

Cerium-141 and cerium-144 are determined in the presence of each other by performing a suitable cerium chemical separation and then measuring the radiation from each nuclide. Cerium-144 is determined by counting the 3.0-Mev Pr144 beta ray; cerium-141 is determined by integrating beneath the 145-kev gamma-ray peak observed with a sodium iodide gamma-ray spectrometer. In the later case correction for contributions from cerium-144 must be made. The gamma/beta branchings for the 145-kev gamma ray in cerium-141 and the 134-kev gamma ray in cerium-144 were determined.
