Wedoany.com Report-May 4, In 2024, the United States operated 94 nuclear reactors across 54 power plants, with a total net generating capacity of nearly 97 gigawatts (GW), making it the world’s largest commercial nuclear power fleet, according to the Energy Information Administration (EIA). The agency reported that France followed with 57 units (63 GW), China with 57 units (55.3 GW), and Russia with 36 units (28.6 GW).

Vogtle-3 began commercial operation in July 2023, Vogtle-4 in April 2024.

Nuclear power contributed 19% of U.S. electricity generation in 2024. The Vogtle nuclear power station in Georgia, the largest in the U.S., operates four reactors with a combined capacity of approximately 4.5 GW. In contrast, the Ginna station in New York, the smallest, has a single 0.6-GW reactor. The EIA noted: “The two reactors at Vogtle and one reactor at Watts Bar in Tennessee are the only new nuclear reactors to come online in the United States since 1996.” Vogtle-3 began operations in July 2023, Vogtle-4 in April 2024, and Watts Bar-2 in October 2016.

Since 2013, 12 U.S. nuclear reactors have permanently closed. However, operational efficiency has improved, with capacity factors rising due to shorter refueling and maintenance outages and enhanced expertise. A spokesperson stated: “US nuclear capacity factors have increased in part because of shorter refuelling and maintenance outages and improved operational experience.”

Recent policies support the continued operation of nuclear facilities. In January 2024, the U.S. Department of Energy (DOE) provided credits to sustain the Diablo Canyon power station in California, which generated 9% of the state’s electricity with its 2.2-GW capacity. The DOE also approved a loan in 2024 to restart the Palisades nuclear power plant in Michigan, potentially marking the first time a retired U.S. nuclear plant resumes operations. The DOE remarked: “If realised, the project would see Palisades become the first previously retired nuclear power plant in the US to return to operating status.”

The U.S. nuclear sector remains a cornerstone of the nation’s energy mix, delivering reliable, low-carbon electricity. The fleet’s high capacity factors and strategic investments reflect efforts to maintain operational excellence. The Vogtle and Watts Bar expansions, along with initiatives like Diablo Canyon and Palisades, demonstrate the industry’s focus on meeting energy demands sustainably.

These developments highlight the U.S. commitment to leveraging nuclear power for energy security and environmental goals. Ongoing support from federal policies and innovative operational strategies position the U.S. nuclear fleet to continue leading globally while adapting to evolving energy needs.
