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.

U.S. commercial reactors are designed with excess capacity to allow for a potential uprate. There are three types of uprates: 1) measurement uncertainty recapture power uprates, 2) stretch power uprates, and 3) extended power uprates. Measurement uncertainty recapture power uprates increase the licensed power level by less than 2 percent. They are ...
Since uprates change a reactor’s licensed power level, utilities seek NRC permission to amend their operating license in order to implement a power uprate. The process for requesting and approving a change to a plant's power level is governed by 10 CFR 50.90-92. The applications and reviews are complex and involve many areas of expertise in the NRC...
The NRC has approved 171 uprates and can have several applications for power uprates under review at any given time. Lists of uprate applications approved, under review, and anticipated can be found on the NRC’s website.
The NRC welcomes public involvement in our activities as part of our strong, fair oversight of the nuclear industry. The public’s opportunities to participate in the power uprate arena include: 1. Pre-application meetings, where licensees discuss their uprate plans with NRC staff (some portions of these meetings may be closed to the public to discu...
Feb 19, 2024 · Stretch power uprates are typically between 2 and 7 percent and usually involve changes to instrumentation settings but do not require major plant modifications. Extended power uprates can be as high as 20% and are achieved by significant modifications to major equipment such as high-pressure turbines, condensate pumps and motors, main generators, and/or transformers.
Jan 7, 2022 · For nuclear power plants, uprates are another appealing way to maximize existing economic and political investments and to compound the environmental benefits of carbon-free nuclear power. Reactor uprates fall into two categories: thermal and electrical. Thermal uprates are about getting more power out of the reactor itself.
The process of increasing the licensed power level of a commercial nuclear power plant is called ‘power uprate’. In most cases, this is an economic way of producing more electricity in a nuclear power plant, while maintaining adequate safety, design and operational margins. There are a number of options for uprating the power level and ...

Jan 1, 2013 · Managing power uprates. Power uprating is the process of gaining an increase in the maximum thermal power level of a reactor (therefore, also the electrical output) through regulatory approval, supported by analyses, safety system reviews, system modifications and other actions that may be necessary. 6.3.1.
