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.

Operations are performed on the neutron transport equation in general form to obtain an exact multigroup Fick’s Law formalism consistent with the standard multigroup conservation equation. The inherent accuracy of the transport equation is maintained in the derived form of the spatially dependent “diffusion coefficient,” which is shown to be highly dependent on the angular flux spectra. Numerical investigations on fast reactor configurations substantiate the feasibility of incorporating a transport calculated diffusion coefficient in existing diffusion theory codes for reactor design and analysis with dual utility: (a) the errors in diffusion calculations due to incorrect diffusion coefficients can be separated from boundary-condition errors, and (b) the diffusion calculations of certain parametric design studies can be improved to accuracy approaching that of transport theory using spatially averaged diffusion coefficients obtained from a single transport calculation.
