Nuclear trivia—reveal

The answer: Coming in at 62.98 percent, Unit 2 at Sequoyah nuclear power plant had the lowest DER net capacity factor in the U.S. fleet from 2023 to 2025. That number stands in sharp contrast to the rest of the fleet’s capacity factors. More than half of U.S. reactors come in above 90 percent, and all but five come in above 80 percent. So, what accounts for Sequoyah-2 coming in so far below its peers? A major clue can be found in another dataset. Sequoyah-2 also comes in at the bottom of capacity factor change from 2020–2022 to 2023–2025, having decreased by 26.85 percent. Prior to a significant setback, Sequoyah-2 had a respectable 2020–2022 capacity factor of 89.82 percent, placing it closer to the middle of the pack. However, on July 30, 2024, the reactor unexpectedly shut down. According to the first letter the Tennessee Valley Authority sent to the Nuclear Regulatory Commission on the incident, this automatic reactor trip was “due to an electrical trouble turbine trip,” which was itself the “result of a generator neutral resistor overvoltage relay actuation.” At the time, TVA reported that the root cause for the event was still under investigation. That investigation evolved into an extensive main generator refurbishment that kept the reactor off line for almost a year. After getting back to 100 percent power on June 30, 2025, Sequoyah-2 performed well for the rest of the year, but the time it spent not generating pulled it to the bottom of the fleet in terms of net capacity factor. Go deeper: This story zooms into one small piece of data among dozens upon dozens of figures gathered into this year’s annual Nuclear News feature on the U.S. fleet’s capacity factors.
