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 space-independent reactor kinetics equations with two reactivity feedbacks are analyzed for stability and nonlinear oscillations. Expressions are derived using Fourier series methods for determining the frequency and fundamental amplitudes of the oscillations in reactivity and power. These results are compared with exact solutions of the system equations and agree in all cases for equilibrium power levels near the critical power level. The system of equations is examined for the effect of delayed neutrons on oscillatory solutions. When delayed neutrons are included, unstable limit cycles are found as well as stable limit cycles.
