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.

The advanced nodal code SIMULA TE-3 includes the capability to generate detailed pin-by-pin power distributions. Yankee Atomic Electric Company has performed an extensive series of benchmark calculations verifying the accuracy of this capability. Fuel depletion and fuel depletion after shuffling applications were examined. Comparisons were made among SIMULATE-3, higher order transport theory calculations, and calculations performed using fine-mesh finite difference diffusion theory. Detailed pin power data from multiassembly (colorsets) and quarter-core geometries were compared. The results demonstrate the accuracy of SIMULA TE-3 relative to currently accepted methods of generating pin power data.
