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.

Helium trapping and release are studied for the nickel-rich amorphous alloys Ni75.1 Cr14.0-P10.1C0.08, Ni63.5Zr36.5, and Ni87.7P12.3. Helium-3 is introduced into the samples by implantation at 150-keV energy. The depth distribution of the implanted helium is observed by neutron depth profiling employing the reaction 3He(n, p)3H. Two implantation doses are used: 1 × 1016 and 5 × 1016 3He/cm . Both implantation doses were chosen to be low enough to avoid blistering or flaking of the surface of the samples. The helium release behavior of the samples is studied by taking depth profiles after each annealing stage. At the same time, electron diffraction is used on parallel samples to observe the microstructure of the samples as a function of annealing. The annealing sequence for each material is broken off when electron diffraction indicated the existence of relatively large crystals in a sample. Only a small fraction of the implanted helium is released in most cases, and a clear correlation between helium release and recrystallization can be found in only one case.
