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 transport of heavy particles produced by the 10B(n,α)Li and 235U(n,νn)ff nuclear reactions in a two-region cylindrical geometry is analyzed. Total spatially dependent energy current, power density, and transport efficiency are calculated. These results are significantly different from what would be predicted using a two-region slab model—the model generally used for kinetic analysis of nuclear-pumped plasmas. The calculated transport efficiency for a 0.4 mg/cm2 10B coating was 9% and 16% for a 3.3 mg/cm2 235UO2 coating.
