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.

As part of a comprehensive project to investigate the validity of pulsed-neutron measurements in small systems, we have measured the extrapolation length in a pulsed light-water system with B2 = 0.11/cm2. Space- and time-dependent flux distributions were obtained with a miniature fission chamber and were analyzed by least-squares techniques. Special attention was paid to the extraction of the fundamental mode and to the overall internal consistency of the results. The thermal-neutron extrapolation length, corrected to 20°C, was found to be 0.300 ± 0.015 cm.
