Kathryn Huff

Deploying a fleet of advanced reactors in the 2030s means deploying high-assay low- enriched uranium (HALEU) infrastructure now.

The future fleet will need more than 40 metric tons of HALEU by 2030, according to Department of Energy projections. Getting to the 5–20 percent fissile uranium-235 content of HALEU involves either enriching natural or low-enriched uranium (LEU) or downblending high-enriched uranium (HEU).

Because downblending the limited stocks of HEU held at the DOE’s Idaho National Laboratory and Savannah River Site is a short-term option at best, the Energy Act of 2020 authorized a HALEU Availability Program to build a sustainable enrichment infrastructure by the time advanced reactors are ready for commercial deployment.

Comments on a request for information reached the DOE in February 2022, just before Russia’s invasion of Ukraine amplified global energy security concerns. While the war in Ukraine didn’t change the DOE’s plans, it “accelerated everything,” said Kathryn Huff, who leads the DOE’s Office of Nuclear Energy (DOE-NE) as assistant secretary. “Our attention is now laser-focused on this issue in a way that it wouldn’t have been in the past.”

David Edsey

This past October, the House Select Committee on the Climate Crisis held a hearing titled “Good for Business: Private Sector Perspectives on Climate Action.” The hearing reviewed perspectives on the importance of the government’s investments in climate action and how these investments would contribute to job creation and economic growth. Those testifying included the founder of a solar energy company, the head of communications and policy for a popular outdoors clothing company, a former deputy energy secretary for the Department of Energy, and an executive from an insurance company.

While the solar company founder and the communications head spoke out against nuclear energy, the former deputy energy secretary, during testimony, was in favor of it. The insurance executive, David Edsey, also talked in support of nuclear during the committee’s Q&A session after testimony.

Hurricane

In 2012, Omar Hurricane, a distinguished member of the technical staff at Lawrence Livermore National Laboratory, was asked by the laboratory director to lead a team to delve into studying the physics and engineering obstacles preventing fusion ignition at the National Ignition Facility (NIF). The team’s efforts led to a new exploratory “basecamp” strategy and the creation of several pivotal experiments that revealed some of the underlying problems with the ignition point design, while also delivering improved fusion performance and the first evidence of significant alpha particle self-heating.

Hurricane was appointed chief scientist of the Inertial Confinement Fusion Program in 2014, a position he has held ever since. He was named a Fellow of the American Physical Society’s Division of Plasma Physics in 2016 and was recently awarded the Edward Teller Medal from the American Nuclear Society for his work on inertial confinement fusion physics.

Delbert

This year’s recipient of ANS’s Darlene Schmidt Science News Award is Caroline Delbert, a contributor to the Popular Mechanics magazine and website. The Schmidt Award seeks out journalists and science writers who demonstrate keen effort to report on the work of professionals in the field of nuclear science and technology. In her writing for Popular Mechanics, Delbert regularly covers nuclear, with a focus on advanced reactor designs, fusion energy, nuclear space technology, and non-energy applications of nuclear technology and radiation. This year alone she has published dozens of articles on those topics, and thanks to Popular Mechanics’ cross-publishing across Esquire, Men’s Health, MSN, Yahoo! News, and other platforms, Delbert’s dispatches on nuclear science and technology have reached a wider audience than a nuclear energy beat reporter at a financial website or trade publication could ever reach.

Metz

A number of years ago, historian and writer Chuck Metz Jr. was at the Bush’s Visitor Center in Tennessee’s Great Smoky Mountains when he ran into former Nuclear Regulatory Commission official Harold Denton and his wife. Metz was at the visitor center, which opened in 2010 and is now a tourist hotspot, because, as he explained to the Dentons at the time, he had overseen the development of its on-site museum and had written a companion coffee-table history book.

The chance meeting turned into a friendship and a fruitful collaboration. Denton, who in 1979 was the public spokesperson for the NRC as the Three Mile Island-2 accident unfolded, had been working on his memoir, but he was stuck. He asked Metz for help with the organization and compilation of his notes. “I was about to retire,” Metz said, “but I thought that exploring the nuclear world might be an interesting change of pace.”

Denton passed away in 2017, but by then Metz had spent many hours with his fast friend and was able to complete the memoir, Three Mile Island and Beyond: Memories of a Life in Nuclear Safety, which was published recently by ANS. Metz shared some of his thoughts about Denton and the book with Nuclear News. The interview was conducted by NN’s David Strutz.

In her career as a chemist, Meredith Angwin headed projects that lowered pollution and increased reliability on the electric grid. Her work included pollution control for nitrogen oxides in gas-­fired combustion turbines and corrosion control in geothermal and nuclear systems.

Angwin, an ANS member, was one of the first women to be a project manager at the Electric Power Research Institute, leading projects in nuclear energy and renewables.

In the past decade, Angwin began to study and take part in grid oversight and governance. For four years, she served on the Coordinating Committee for the Consumer Liaison Group associated with ISO New England, her local grid operator. It was during this time that she realized what a maze of confusion surrounded grid rules and grid management.

John Gilligan has been the director of the Nuclear Energy University Program (NEUP) since its creation in 2009 by the Department of Energy’s Office of Nuclear Energy (DOE-NE). NEUP consolidates DOE-NE’s university support under one program and engages colleges and universities in the United States to conduct research and development in nuclear technology. The two main R&D areas for NEUP funding are fuel cycle projects, which include evolving sustainable technologies that improve energy generation to enhance safety, limit proliferation risk, and reduce waste generation and resource consumption; and reactor projects, which strive to preserve the existing commercial light-water reactors as well as improve emerging advanced designs, such as small modular reactors, liquid-metal-cooled fast reactors, and gas- or liquid-salt-cooled high-temperature reactors.

Ratliff

Harris

When Floyd Harris began working at Duke Energy’s Brunswick nuclear plant about 24 years ago as a radiation protection technician, robotics and remote monitoring were considered tools for radiation protection and nothing more. Now, teams from across the site, including engineering, maintenance, and operations, rely on the system of robots and cameras Harris is responsible for. “If you want to put those technologies under one umbrella,” says Harris, who now holds the title of nuclear station scientist, “it would be monitoring plant conditions.”

That monitoring is critical to effective plant maintenance. As Plant Manager Jay Ratliff explains, the goal is to “find a problem before it finds us” and ensure safety and reliability. Nuclear News Staff Writer Susan Gallier talked with Ratliff and Harris about how robotics and remote systems are deployed to meet those goals.

At Brunswick, which hosts GE-designed boiling water reactors in Southport, N.C., ingenuity and hard work have produced a novel remote dosimetry turnstile to control access to high-radiation areas, an extensive network to handle data from monitoring cameras, rapid fleetwide access to camera feeds to support collaboration, and new applications for robots and drones.

Eric Goldin, president of the Health Physics Society, is a radiation safety specialist with 40 years of experience in power reactor health physics, supporting worker and public radiation safety programs. A certified health physicist since 1984, he has served on the American Board of Health Physics, and since 2004, he has been a member of the National Council on Radiation Protection and Measurements’ Program Area Committee 2, which provides guidance for radiation safety in occupational settings for a variety of industries and activities. He was awarded HPS Fellow status in 2012 and was elected to the NCRP in 2014.

Goldin’s radiological engineering experience includes ALARA programs, instrumentation, radioactive waste management, emergency planning, dosimetry, decommissioning, licensing, effluents, and environmental monitoring.

The HPS, headquartered in Herndon, Va., is the largest radiation safety society in the world. Its membership includes scientists, safety professionals, physicists, engineers, attorneys, and other professionals from academia, industry, medical institutions, state and federal government, the national laboratories, the military, and other organizations.

The HPS’s activities include encouraging research in radiation science, developing standards, and disseminating radiation safety information. Its members are involved in understanding, evaluating, and controlling the potential risks from radiation relative to the benefits.

Goldin talked about the HPS and health physics activities with Rick Michal, editor-in-chief of Nuclear News.

Penfield

Enos

Energy Harbor’s Beaver Valley plant, located about 34 miles northwest of Pittsburgh, Pa., was one of many nuclear sites preparing for a scheduled outage as the coronavirus pandemic intensified in March. The baseline objective of any planned outage—to complete refueling on time and get back to producing power—was complicated by the need to prevent the transmission of COVID-19.

While over 200 of the plant’s 850 staff members worked from home to support the outage, about 800 contractors were brought in for jobs that could only be done on-site. Nuclear News Staff Writer Susan Gallier talked with Beaver Valley Site Vice President Rod Penfield and General Plant Manager Matt Enos about the planning and communication required.

Beaver Valley can look forward to several more outages in the future, now that plans to shut down the two Westinghouse pressurized water reactors, each rated at about 960 MWe, were reversed in March. “The deactivation announcement happened in the middle of all our planning,” Enos said. “It’s a shame we haven’t had a chance to get together as a large group and celebrate that yet.”

While the focus remains on safe pandemic operations, the site now has two causes for celebration: an outage success and a long future ahead.

Smith: “We look at these changes as very positive for our business and the industry, as tapping into these technologies will drive down costs and improve efficiencies.”.

VanTassell: “Why should the experience of buying nuclear parts be any different from the online experience of buying household items? We all want to get what we need quickly, efficiently, and at a good value.”.

In February of this year, Paragon acquired Nuclear Logistics LLC to form a third-party supplier of equipment solely focused on the nuclear industry. Engineering, design, manufacturing, testing, and qualification are performed in Paragon’s three facilities, located in Fort Worth, Texas, Oak Ridge, Tenn., and Schenectady, N.Y.

Its work includes decommissioning nuclear power plants and safely containing, transporting, recycling, processing, and disposing of nuclear material.

Dempsey talked about the company’s cask and container activities with Nuclear News Editor-in-Chief Rick Michal.

David Gandy, the senior technical executive for nuclear materials at the Electric Power Research Institute, is charged with leading a project to lower the costs and manufacturing time for small modular reactors and advanced reactors. The Department of Energy–funded project is led by EPRI, and its collaborators include the United Kingdom–based Nuclear Advanced Manufacturing Research Center and Oregon-based reactor developer NuScale Power. The testing has focused on producing the upper and lower pressure vessel assemblies for NuScale’s 60-megawatt SMR.

Gandy said that the project team has already produced a 3,650-pound reactor upper head at 44 percent scale and has made other components as heavy as 7,000 pounds. Over the next two years, if the tests still to be conducted are successful, EPRI plans to transfer the technologies to other reactor manufacturers. Gandy expects these new technologies to be available in about five to seven years, once the testing is completed and the necessary approvals are obtained from the Nuclear Regulatory Commission and ASME.

Gandy talked about the project with Nuclear News Editor-in-Chief Rick Michal.

Winters

Dennis Wilkinson would have celebrated his 100th birthday on August 10, 2018. The life and career of the man who captained the first nuclear-powered submarine and the first nuclear-­powered surface ship and was the first president and chief executive officer of the Institute of Nuclear Power Operations (INPO) have been captured in Ann Winters’s book, Underway on Nuclear Power: The Man Behind the Words, Eugene P. “Dennis” Wilkinson, Vice Admiral USN.

Because of his inherent drive, Wilkinson was often called a cowboy, maverick, visionary, innovator, and superb leader. As the first commanding officer of USS Nautilus, he was a major player in revolutionizing underwater warfare. Nautilus and its crew were immensely popular, at home and abroad, and in the 1950s became what we now call “rock stars.” Nautilus gave nuclear power celebrity status at a time when the United States and the world were grappling with Cold War issues.
