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.

As a result of experiments with the Upper Plenum Test Facility and the 1400-MW(electric) Advanced Power Reactor (APR1400), sweepout in the downcomer has been identified as playing an important role in the depletion of the core coolant inventory during a large-break loss-of-coolant accident. In order to identify the sweepout mechanism and estimate the amount of coolant discharged during sweepout, separate-effects tests were performed in a rectangular-type test apparatus 1/5 the scale of the APR1400 downcomer. The experimental results showed that the sweepout was dominantly influenced by the hydraulic behaviors of coolant and steam near the intact cold leg. A sweepout model was developed by correlating the experimental results to analytically derived nondimensional parameters. The developed model showed applicability to the prototype, as the experimental results of the counterpart tests were in good agreement, within <25.0% of the uncertainty band.
