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.

An experimental test of several equivalence relations for effective resonance integrals is obtained from measurements of U238 resonance escape probability for lattices of the TRX critical facility, and measurements of the U238 resonance integrals of isolated rods of UO2 and uranium metal. The TRX lattices were H2O-moderated and composed of cylindrical, aluminum-clad fuel rods of slightly enriched uranium metal or UO2. The measurements are in agreement with two forms of equivalence among lattice and isolated rod resonance integrals for a given fuel composition. The equivalence between resonance integrals for fuel rods of different compositions (IT and UO2) does not appear to be as good.
