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 moments method has been used to calculate the flux age at 1.44 ev in D2O and D2O-H2O mixtures of neutrons from various point isotropic sources. For the neutrons from a D-D source averaged overall solid angle and operating at a deuteron energy of 200 kev, the age in 99.8% D2O was computed to be 118.6 ± 1.2 cm2, in good agreement with the experimental value of Spiegel and Richardson. The rate of change of age for this source with very small admixtures of H2O was found to be —4.5% per 1% H2O, which agrees with the results of experiment and other calculations. Flux ages to 1.44 ev were also calculated for seven monoenergetic point sources from 2.00 to 2.98 Mev in energy. The approximate linearity of these ages with source energy is used to show that uncertainties in the angular distribution of the D-D source neutrons have a negligible effect on the averaged age. It is also shown that the 2.4 Mev antiresonance in oxygen is manifested in the age in D2O only as a correction to the first flight term.
