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.

Experimental measurements of the gamma-ray pulse-height distributions due to the products of fast-neutron-induced fission of 235U and 238U are presented. The measurements were made at nine selected times, ¼, ½, 1, 2, 5, 10, 24, 48, and 72 h after fission. Irradiation times and counting intervals were chosen to minimize saturation and decay effects. The experimental data were used to calculate 100 energy bin distributions of the absolute number of photons/(fission sec) by means of absolute calibrations of the collimated NaI(Tl) detector. The number of fissions in each sample was determined radiochemically. Machine computation was used extensively.
