Baseload nuclear generation doesn’t get the respect it deserves, if you ask nuclear operators. But the hyperscale data centers that process our digital lives—like the one right next to the Susquehanna plant in northeastern Pennsylvania—are pushing electricity demand up. Clean, reliable capacity now looks a lot more valuable.

Another year, another stellar performance by America’s nuclear plants. We’ve come to expect high capacity factors, and it’s a credit to the men and women of the profession. They’ve made routine something that was unimaginable not so long ago.

The decadal challenge for the nuclear enterprise now is to maintain this high level of operational excellence for the current fleet, while at the same time ushering in a new generation of technologies at scale. It will be a big job—but one that seems more and more likely with each passing day.

It is against this hopeful backdrop that I take the opportunity to update you on our latest steps toward making the American Nuclear Society a class-leading professional society.

The World Nuclear Performance Report 2023 has been released by the World Nuclear Association (WNA), containing a mix of positive and negative news about the global nuclear power industry. On the positive side, according to the report, nuclear energy in 2022 supplied approximately 10 percent of the world’s electricity and roughly 25 percent of low-carbon clean electricity (second only to hydropower). On the negative side, the total amount of electricity supplied by nuclear energy declined by 4.2 percent in 2022 compared with the previous year, and the nuclear industry as a whole is “not growing fast enough to address the challenges of ensuring energy security, tackling climate change, and providing access to clean energy for all,” said WNA director-general Sama Bilbao y León in remarks at the launch of the report.

In the early years of the Nuclear News capacity factors survey, any factor over 70 was deemed excellent; any factor under 50 was considered poor. By that standard, all but two operating U.S. power reactors chalked up excellent performance during 2017–2019. A record 809.4 TWh of electricity was generated in the United States from nuclear energy in 2019, according to the U.S. Energy Information Administration (EIA), besting the record of 807.1 TWh set in 2018.

Nuclear News staff developed the capacity factors survey in the early 1980s as a way to identify the most productive reactors in an expanding fleet. Fleet improvement was the industry’s self-identified goal, but no one could anticipate the startlingly rapid pace of improvement, spurred by the Institute of Nuclear Power Operations (INPO), which boosted fleetwide performance to highs that continue today.
