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.

Potential-pH diagrams are reported for uranium and plutonium in water containing carbonate, chloride, fluoride, phosphate, sodium, and sulfate ions at 25, 100, and 200°C Complexation was considered in deriving the diagrams and the potential-pH relationships were calculated for various total dissolved ion concentrations. The diagrams are used to analyze the general features of the thermodynamic behavior of uranium and plutonium in geological systems and to help identify processes that might be expected to occur in the vicinity of a deep underground vault for nuclear fuel waste.
