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 “spring model” belongs to the class of single bubble models in the sense that it is based on the concept of a vapor bubble bounded by an upper and a lower plane interface across which mass, energy, and momentum are transferred. It is characterized by the hypothesis that the bubble transformations occur under adiabatic conditions. From the numerical point of view, it is very simple and requires a very short computing time. The model and its name were suggested by the analysis of the damped oscillations of the pressure observed during one of the single-pin boiling tests performed on the ENA-2 loop. Pressure, temperatures, and void fractions calculated by the spring model were compared with the experimental ones and very good agreement was observed in this case.
