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 sample of (U,Pu)-mixed oxide was fission heated along the saturation line and into the compressed liquid regime. The density of the sample at temperatures around 7000 K was determined from the onset of the liquid-phase pressure signal. Values for the compressibility of the (U,Pu)-mixed oxide were determined from the slope of the measured pressure/time signal. Based on these results and earlier measurements, new relations are proposed for the following properties: the density/enthalpy, density/temperature, thermal expansion/temperature, and isothermal compressibility/temperature relations. The ranges of validity are 1400 to 3600 kJ/kg and 3120 to 7600 K, respectively. The property relations are recommended for both liquid UO2 and (U,Pu)O2 with yPu ≤ 0.25. The measured data strongly suggest that the critical temperature of (U,Pu)O2 is well above 8000 K.
