1. • • These “uprates,” when we’re satisfied they’ll be done safely, can involve changes to a reactor’s instruments, controls and power generation systems. Over the past 20 years, we’ve approved uprates that have given the nation’s electricity grid an additional six gigawatts, the equivalent of six large reactors.

   What is a power uprate?

   • The process of increasing the maximum power level at which a commercial nuclear power plant may operate is called a power uprate. Did you know U.S. nuclear power plants can ask the NRC for permission to increase their power output?

   What are extended power uprates?

   • Extended power uprates are greater than stretch power uprates and have been approved for increases as high as 20 percent. These uprates require significant modifications to major balance-of-plant equipment such as the high pressure turbines, condensate pumps and motors, main generators, and/or transformers.

   How many nuclear uprate requests have been approved?

   • The Nuclear Regulatory Commission (NRC) reviews uprate requests from a nuclear utilities to assure the continued safe operation of these plants; uprates may not be implemented without NRC approval. Since the first requests in 1977, the NRC has approved 144 uprates.

   What is an extended uprate?

   • Extended uprates increase electrical output by more than 7% and can be as large as 20%. Extended uprates generally involve significant plant modifications and may take years to fully implement. To date, the NRC has approved 26 extended uprates, totaling about 2,883 MWe.

   What is a nuclear uprate?

   • Uprating generally involves physically modifying the plant to increase its generating capacity. Since 1977, more than 6,500 megawatts-electric (MWe) of nuclear uprates have been approved, and most of these have already been implemented.

   Nov 20, 2013 · Occasionally, a nuclear plant will request an “ uprate ” as a way to increase the amount of electricity the unit is allowed to produce. An uprate, however, must be approved by the NRC. Approximately 139 uprates, resulting in a net gain of more than 18,000 MW have been approved by the NRC.
