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.

A mathematical model for the calculation of kinetic-energy spectra of fragments from the spontaneous fission of 252Cf has been developed. This model predicts the spectra of these fragments after transmission through any absorber whose thickness and composition are known. The model may be applied to other fissioning elements with minor modifications. Agreement between calculated and experimentally observed peak positions agree to within 5%. The energy shifts due to an absorber may be calculated to within 25% for the thicknesses of foils used.
