The pursuit of returning two of the country’s retired nuclear plants into service is not only unusual—it is unprecedented and promises to make history.

That’s according to a piece coauthored by former assistant secretary for nuclear energy Katy Huff in the Bulletin of the Atomic Scientists regarding plans from Holtec and Constellation to restart Michigan’s Palisades plant and Pennsylvania’s Three Mile Island Unit 1, respectively.

On the company’s earnings call this month, Constellation CEO Joe Dominguez was asked if there is a possibility of restarting the shuttered Three Mile Island plant—as is being proposed for the Palisades nuclear plant in Michigan.

“We’re not unaware that opportunity exists for us,” Dominguez said. “We’re obviously seen what’s happened with Palisades and I think that was brilliant. Brilliant for the nation. … We are doing a good bit of thinking about a number of different opportunities, and that would probably certainly be one of those that we would think about.”

Remembering ANS Past President Joseph Hendrie

January 11, 2024, 3:01PMNuclear News

Joseph Hendrie, Brookhaven National Laboratory physicist, NRC chair, and ANS past president (1984–1985), passed away in his home in Bellport, N.Y., on December 26 at the age of 98.

Hendrie, an American Nuclear Society member since 1956, was a leader in the nuclear community for much of his 45 years in nuclear reactor safety research. He served as the deputy director for technical review of the Atomic Energy Commission’s Directorate of Licensing from 1972 to 1974 and then was appointed chair of the NRC in 1977 (serving a second stint as chair in 1981—the only person to serve two nonconsecutive terms in that role).

U.S. nuclear capacity factors: Credits where due

April 28, 2023, 3:03PMNuclear NewsSusan Gallier

Forty years ago, Nuclear News published an analysis of U.S. nuclear plant operations over the three years that followed the Three Mile Island-2 accident in 1979, scrutinizing capacity factors as a measure of how well a reactor was performing compared to its potential. The purpose: “To call attention to the units that have had the best results, and to explore the question: What have the personnel at these top units been doing right?”

Nuclear energy is uniquely poised to create reliable, carbon-free, domestically produced baseload electricity to meet our rising energy demands. It must be a central part of our energy mix in order to have sustainable development, competitiveness, and independence as global energy demand continues to grow. There is also a growing need to address national security challenges like nuclear proliferation resistance and nuclear threat reduction. The fastest and most efficient way to realize the full potential of nuclear power and address nuclear security challenges is to draw on the strengths of our universities, national laboratories, and industry.

U.S. universities are well equipped to be the preeminent providers of nuclear science and engineering education at the undergraduate, graduate, and postgraduate levels and to perform world-class research across all nuclear science and engineering disciplines, utilizing the resources available across the higher education network and through unique national laboratory partnerships.

Freakonomics podcast focuses on nuclear energy and climate change

October 10, 2022, 7:01AMANS Nuclear Cafe

On a recent Freakonomics Radio podcast, host Stephen J. Dubner and his guests explored the topic of nuclear power. The episode, “Nuclear Power Isn’t Perfect. Is It Good Enough?” was teased on the podcast website with this thought: “Liberals endorse harm reduction when it comes to the opioid epidemic. Are they ready to take the same approach to climate change?”

Lake Barrett’s reality-grounded perspective on Netflix’s drama Meltdown: Three Mile Island

June 10, 2022, 7:00AMANS News

In an ANS-sponsored online event held on June 8, independent energy consultant Lake Barrett shared his perspective on the Netflix docudrama series Meltdown: Three Mile Island. Barrett, who was the Nuclear Regulatory Commission’s on-site director and senior federal official for the cleanup of the TMI Unit 2 accident in the early 1980s, countered inaccuracies in the series during an interview with ANS Executive Director/CEO Craig Piercy.

Meltdown: Drama disguised as a documentary

June 3, 2022, 7:02AMANS Nuclear CafeJohn Fabian
The cooling towers of Unit 2 at Three Mile Island Nuclear Generating Station, closed since the accident in 1979.

The Three Mile Island accident in 1979 was the most-studied nuclear reactor event in the U.S. There is a plethora of research about the accident available to the general public, including the president-appointed Kemeny Commission report and the Nuclear Regulatory Commission’s Rogovin inquiry report (split into volume one, and volume two, parts one, two, and three), which are the two detailed government-sponsored investigations into the accident. There are also thousands of documents in the NRC’s ADAMS database available to the public, an excellent overview by NRC historian Samuel Walker Three Mile Island: A Nuclear Crisis in Historical Perspective, as well as the Nuclear News special report from April 1979, and articles written by ANS members like William Burchill about the accident and the many changes it forced on the industry. If the producers of Meltdown: Three Mile Island—available on Netflix—had read any of those documents instead of relying mostly on input from antinuclear activists, their “documentary” might have been presented with at least some sense of balance and credibility.

Instead, similar to a recent Science Channel documentary on the Three Mile Island accident, Meltdown focuses on drama instead of science. This four-part miniseries does not attempt to provide a balanced set of facts from the technical community and instead relies heavily on nonexpert opinions and anecdotal statements to tell a story that easily falls apart under even the faintest scrutiny.

Nuclear News reached out to multiple ANS members who were involved with either the accident response or the clean up to help provide a critical look at some of the more egregious statements made in the documentary.

The Kemeny Commission Report from the pages of Nuclear News

May 26, 2022, 3:15PMNuclear News

This week’s Throwback Thursday post is again about Three Mile Island—this time looking at the coverage from the pages of the December 1979 issue Nuclear News about the Kemeny Commission. The twelve-person commission, announced by President Carter immediately after the accident in April 1979, was headed by John Kemeny—then president of Dartmouth College—with orders to investigate the causes and any consequences of the accident.

Part one of this article, published in the May 2019 issue of Nuclear News[1] and last Friday on Nuclear Newswire, presented insights from the 1979 accident at Three Mile Island-­2 and addressed several issues raised by a previous Nuclear News piece on the accident[2]. Part two discusses safety improvements that have been made by both the industry and the Nuclear Regulatory Commission over the past 40 years.

Insights from the Three Mile Island accident—Part 1: The accident

April 29, 2022, 3:59PMNuclear NewsWilliam E. Burchill

The accident at Unit 2 of the Three Mile Island nuclear power plant on March 28, 1979, was an extremely complex event. It was produced by numerous preexisting plant conditions, many systemic issues in the industry and the Nuclear Regulatory Commission, unanticipated operator actions, previously unrecognized thermal-­hydraulic phenomena in the reactor coolant system (RCS), and the unprecedented challenge of managing a severely degraded core.

In focus: The Three Mile Island special report

April 28, 2022, 3:00PMNuclear News

This week’s #ThrowbackThursday post features the special report published by Nuclear News in April 1979—one month after the accident at the Three Mile Island nuclear power plant. Titled “The ordeal at Three Mile Island,” the report provides readers with a quick review of the accident, how it happened (as much as was known at the time), its immediate effects on the general public, and the public discourse that followed. It should come as no surprise that the report covers some negative responses from the public and politicians of the time, but it concludes with the responses of some policy leaders who tried to put the accident into perspective.

Looking back at coverage of TMI
