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 solvent extraction process for separating americium and curium from major portions of rare earths has been developed using tracer americium and curium. Rare earth elements are extracted from 10 M LiCl solutions (with HCl varying from 0.5 to 1.0 M) into 0.5 M mono-2-ethylhexyl orthophosphoric acid in xylene carrier. The americium and curium remain in the lithium chloride solution. Americium is separated from all rare earths, and curium from all rare earths except lanthanum by countercurrent extraction. The extractability of the rare earths, americium, and curium in 10 M LiCl is affected by the HCl feed, the rare earth concentrations in the feed, the organic extractant concentration, and the nature of the diluent.
