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 one-dimensional nuclear reactor kinetics equation with feedback is solved by a perturbation method that gives asymptotically stable solutions for a step input of reactivity. The transient solutions are obtained by expanding each perturbation term in a series of spatial modes and applying Laplace transforms. It is shown that assuming the initial fuel temperature distribution is not equal to the coolant temperature distribution, the asymptotic flux depends on the initial state of the system if the harmonics are taken into account. This conclusion is further reinforced by analyzing the solution of the nonlinear spatial problem representing the final equilibrium state in terms of the solutions of the nonhomogeneous Mathieu equations.
