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.

Criteria for nonlinear asymptotic stability of nuclear reactor systems repre-sentable by point reactor kinetics are derived. The reactor system model includes all delayed neutron precursors and linear feedback. The results are also extended to systems where the feedback is not linear., A procedure is outlined for the interpretation of the criteria by means of small-amplitude perturbation tests. The procedure is illustrated by using experimental transfer function measurements from Experimental Boiling Water Reactor.
