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.

Reactor physics calculations were performed with ENDF/B Version-Ill cross-section data for several of the fast-reactor data-testing assemblies specified by the Cross Section Evaluation Working Group. In these calculations, multigroup cross sections were generated using both the Argonne MC2 and SDX codes for comparative purposes. The multigroup cross sections were then used in Sn transport-theory calculations to obtain keff and central activation ratios, and in perturbation-theory calculations to obtain central worths. Results with MC2 and SDX cross sections are in good agreement except when regions containing large amounts of a structure material are involved.
