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.

A source iteration scheme and associated diffusion-synthetic acceleration scheme are defined for the even-parity Sn equations with anisotropic scattering. The spatially analytic versions of these schemes are shown to be completely equivalent to their counterparts for the first-order form of the equations. Thus, in the limit as the spatial mesh is refined, each even-parity iteration scheme must asymptotically converge at the same rate as its first-order counterpart. The equivalence of the even-parity and first-order source iteration processes implies that any synthetic acceleration scheme for the first-order Sn equations has an even-parity counterpart that is equivalent for the spatially analytic case. Theoretical and computational results are given that demonstrate the properties of the even-parity source iteration and diffusion-synthetic acceleration schemes.
