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.

Absolute cross-section measurements for reactions among light-mass nuclei (A < 10) are important in feasibility studies of controlled thermonuclear reactor systems. For a 6Li-d fueled fusion reactor, the 6Li (p,3He)α reaction is of particular interest. The absolute cross sections for this reaction are incomplete and poorly known and have accordingly been remeasured in the range Ep = 3 to 12 MeV. The results support recent measurements below 3 MeV in finding the cross section to be higher in this region than previously supposed. Additional results for the 6Li(p,p)6Li and 6Li(p,p′)6Li* reactions imply the cross sections for these reactions are ∼40% higher than earlier measurements. A plot of the Maxwell-averaged reaction rate parameter, , for the 6Li(p,3He)α reaction is presented as a function of kT, the temperature of a p – 6Li plasma.
