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.

Correlations of experimental data on heat transfer from nonboiling, horizontal fluid layers with internal heat generation have been cast into a form suitable for analysis of postaccident heat removal in fast reactors. Available data on layers with equal boundary temperatures indicate that the downward heat transfer rate can be accounted for by conduction alone, while the upward heat transfer rate is largely controlled by convection. A new correlation is presented that applies to evaluation of upward and downward heat fluxes from an internally heated layer with unequal boundary temperatures. Analysis techniques are illustrated in an example calculation pertaining to layers of molten mixed-oxide fuel.
