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.

Gamma-ray transition probabilities intended for use in the preparation of gamma-ray production cross sections have been calculated for four odd-A nuclei and compared with experiment. Wave functions used in the calculation of M1 and E 2 transition matrix elements were generated with a deformed shell (Nilsson) model code which allows for asymmetric quadrupole deformations. Inverse moments of inertia and deformations were treated as adjustable parameters. The collective gyromagnetic ratio was assumed to be a constant for all levels. The results suggest in the context of the simplified model an angular momentum dependence of the nuclear deformation.
