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.

A test rig was built to run steady-state experiments with air/water mixtures at low pressure (42 kPa), and to determine the performance characteristics of two-phase flow through a centrifugal pump. Application is to a loss-of-coolant accident situation in nuclear reactor power plants if a large break in one of the primary pump legs took place. Two feasible accident conditions were tested; first- (forward flow and rotation) and third-quadrant (reverse flow and rotation) conditions. A significant head-pump degradation process was observed in the first-quadrant operation for increasing amounts of gas supplied, whereas in the third quadrant no difference in performance was detected with respect to single-phase flow and up to an inlet volumetric quality of 20%. The data gathered have been correlated in terms of a defined head-loss ratio, flow coefficient, and volumetric quality, which facilitates its use in predicting pump performance in similar designs of different scale.
