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.

For nodal light water reactor calculations, the reconstruction of local multigroup neutron flux and current distributions within a node is discussed. Interpolation schemes that exploit the typical behavior of multigroup neutron spectra are proposed. These spectral interpolation schemes will be seen to be more accurate than the usual polynomial approaches. They reduce the error of pin power interpolation to that of fast flux interpolation. Thus the accuracy of one node per assembly calculations is considerably enhanced. The improvement is demonstrated by several benchmark problems.
