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.

Studies have been conducted at the Transient Reactor Test Facility (TREAT) to determine the variation during transient irradiation experiments of the ratio of axial midplane test fuel power to reactor power as measured by ex-core ion chamber current. It is shown that the dependence of this ratio on core temperature is generally small. However, effects due to control rod motion can be substantial. A simple mathematical expression that predicts the dependence of this ratio on control rod position is shown to give good agreement with integral experimental data. This work makes possible refinements in obtaining the desired power-versus-time behavior in test fuel by accounting for the effects of instantaneous position of control rods and core temperature during transient operation.
