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.

Depletion perturbation theory was developed within the framework of an advanced hexagonal nodal diffusion method. A similarity transformation method was used to compute the mathematical generalized adjointsfrom the corresponding physical system because it was more convenient to utilize the numerical algorithms and codes developed for solving the real system equations. The methods were implemented using the DIF3D code for the flux solutions and were applied to a sample problem using a hexagonal geometry lattice. In all cases, there was good agreement between the results of direct subtraction and the depletion sensitivities. This work indicates it is feasible to generate depletion sensitivities within the framework of advanced nodal diffusion methods.
