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.

It is well known that for a large reactor a diffusion calculation of the system eigenvalue (criticality) is weakly dependent on the linear extrapolation distance γ. We characterize this weak dependence by a smallness parameter ϵ, and show that the complete neglect of γ leads to an error in the computed eigenvalue of the order of ϵ, whereas the use of an extrapolated endpoint introduces an error of the order of ϵ2. An explicit formula, which preserves the ϵ2 error characteristics, is derived which gives an energy independent extrapolated endpoint in terms of the energy-dependent linear extrapolation distance.
