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.

Equations, tables, and charts are given which represent the equilibrium distribution of uranyl nitrate and nitric acid between aqueous solution and an organic phase consisting of 30 vol% tributyl phosphate (TBP) in a hydrocarbon diluent at 25°C. These should be useful for prediction of distribution equilibria in the Purex solvent extraction process for recovering uranium from irradiated nuclear fuel. Equations for the aqueous phase represent the activities of water, nitric acid, and uranyl nitrate hexahydrate as functions of the molality of the last two components. These equations were developed by correlating data for the partial pressure of nitric acid over aqueous solutions of nitric acid and uranyl nitrate. Distribution equilibrium data for uranyl nitrate are correlated by an equation representing the ratio of the activity coefficient of the uranyl nitrate-TBP complex to the activity coefficient of uncomplexed TBP as a function of the uranyl nitrate and nitric acid content of the organic phase. This equation was fitted to distribution data for uranyl nitrate observed in the presence of nitric acid and in the absence of nitric acid. The observed molality of uranyl nitrate in the organic phase agrees with the molality predicted by this equation within an average deviation of 5.8%. Distribution equilibrium data for nitric acid in the presence of uranyl nitrate were correlated in analogous fashion.
