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.

Equipment that is one-tenth the size of the steam generators for the Westinghouse 900-MW(electric) nuclear power plants is used to study the swell and shrinkage of the water level. The cyclic aspect of level swell and shrinkage occurring during low-power operation of the nuclear power plants is realized by sequential steam dump valve control. Experimental results show that a simple mathematical model based on the amount of steam generated during depressurization provides a good approximation for predicting level swell and shrinkage. Steam generation also causes water movement between the downcomer area and the inner part of the vessel, the effect of which during the initial steam dump period is estimated and applied to adjust this model.
