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 total neutron cross section of 147Pm has been measured from 0.01 to 1000 eV, using compacted oxide samples in the Materials Testing Reactor (MTR) fast chopper. After correcting the data for decay product 147Sm content and water contaminant bias, the total cross section of 147Pm at 0.0253 eV was found to be b. Resonance parameters were determined up to 250 eV by shape-fitting and area analysis, and a negative energy resonance has been postulated to fit the data at thermal. From these parameters a resonance absorption integral of 2192 ± 100 b and a neutron s-wave strength function have been obtained.
