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 attenuation cross sections of the elements copper, zirconium, silver, and tin have been measured experimentally in a narrow beam good geometry set up by employing a high-resolution hyperpure germanium detector in the energy range 5 to 85 keV. The data have been used to derive the K-shell photoeffect cross sections at the K-edge, the oscillator strength gK, and the K-jump ratio of the elements copper, zirconium, silver, and tin. The photoeffect cross sections at the K-edge and the oscillator strengths of the element have been calculated by making use of a method that eliminates the requirement of subtracting the theoretical scattering contribution. The best-fit coefficients for the cross sections and the relations so obtained for the jump ratios and oscillator strengths facilitate a speedier E- and Z-wise interpolation of the data on total attenuation cross sections as well as JK and K-shell photo effect cross sections at the K-edge, respectively, in the range 5 to 85 keV, for elements in the atomic number range 25 to 55.
