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.

The Tramex Process for separating the transplutonium elements from ionic impurities and fission products, including the rare earths, was developed and tested in laboratory scale experiments. This process is based on tertiary amine extraction of transplutonium elements from concentrated lithium chloride solutions. Single-stage separation factors between the transplutonium and the lanthanide elements were found to be ≧100. Extraction positions were found to be Cf > Fm > Es > Bk > Am > Cm ≫; lanthanides. Extraction coefficients were directly proportional to the square of the amine concentration in the solvent, directly proportional to the 17th power of the LiCl concentration in the aqueous phase, and inversely proportional to the 1.3 to 2.0 power of the acid concentration in the aqueous phase. Extraction coefficients were affected by the presence of various contaminant anions and were also dependent upon the solvent used to dilute the amine.
