Operators Seek Higher Output by Upgrading Decades-Old Nuclear Reactors
Companies are turning to power uprates—modifying existing nuclear plants to boost electricity output.
Facing long construction times, many operators are opting for power uprates, which involve retrofitting components such as controls, turbines and pumps to increase generation capacity. This approach promises faster, cheaper capacity gains than building new reactors. The trend reflects a shift toward maximizing existing infrastructure.
Why it matters
Boosting output from existing reactors can lower costs and help meet energy and climate targets faster.
