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.

A multivariable theory is applied to the design of the recirculation and feed water control systems of a boiling water reactor. The nuclear steam supply system simulation model is represented by a set of 14 first-order nonlinear ordinary differential equations. Linearization about a steady-state operating point leads to a linear model. To reduce the computational effort, a sixth-order model is obtained by an optimal order reduction method. A robust controller is designed so that the regulation and tracking capability holds in the presence of certain perturbations and disturbances to the plant. The controller parameters are obtained by the parameter optimization method. The results of simulation show that the control system performs well and has robust stability.
