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.

An experiment to measure the detailed energy, angular, and spatial distribution of neutrons originating from a 14-MeV neutron source in liquid air is presented. The neutron spectra are measured with a proton-recoil NE213 scintillator combined with a collimator. The measurements cover the energy range from 2 to 18 MeV at eight different angles from 0 to 90 deg. The distance between the neutron source and the measurement position varies from 60 cm (52 g/cm2) to 150 cm (130 g/cm2) in liquid air. The results are discussed and compared with known theoretical neutron transport calculations.
