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.

The Special Measurements Group at the Brookhaven Alternating Gradient Synchrotron has conducted detailed experiments to evaluate and understand radiations emanating from the accelerator. As a part of this group study, skyshine and attenuation through Long Island sand was measured. Attenuation 90° from the apparent line source followed a half thickness of about one foot of sand through at least four decades. This corresponds to an attenuation length in sand of 80 g/cm2., Skyshine was measured out to 1000 m from the target. The empirical results fit the following expression for 4.2 × 1011 protons/sec on target: I = (3000/r2) exp(-r/600) [1 - exp(r/47)] where I is the dose rate in mrem/h and r is the source detector distance in meters. The source luminosity was determined, and a skyshine function was derived, based on the luminosity and the expected attenuation in air based on sand results. The empirical function was found to be within 25% of the derived expression.
