Extracting efficiency
Craig Piercycpiercy@ans.org
May is a month when we pause—briefly—to recognize something that too often goes unsaid: the extraordinary performance of the existing U.S. nuclear fleet. Capacity factors remain above 90 percent (with a median of 91.29 for the three-year period 2023–2025—see Nuclear News, May 2026, p. 24), an impressive figure delivered at a scale unmatched anywhere else on the globe. That level of sustained output is not an accident of design; it is a daily achievement. It reflects the discipline, professionalism, and pride of the men and women who operate and maintain these facilities, often without fanfare.
In this issue, you will also read about the important work researchers at our national laboratories are doing to extract even greater efficiency from the plants we already have. That effort deserves more attention, because it points to a fundamental truth: the fastest, most reliable way to expand nuclear generation in the United States is not solely through new builds—it is by maximizing the assets already on the grid.
With over 12,000 readers throughout 54 countries, Nuclear News is recognized worldwide as the flagship trade publication for the nuclear community. News reports cover plant operations, maintenance and security; policy and legislation; international developments; waste management and fuel; and business and contract award news. The magazine has been published by the American Nuclear Society since 1959.
