Seventy years ago to the day, President Dwight D. Eisenhower gave his historic address to the United Nations General Assembly in New York City. (See December 2023 Nuclear News's “Leaders” column to read the reflections of Kathryn Huff, the Department of Energy’s assistant secretary for nuclear energy, on the speech’s anniversary.)
This spring, Waste Management Symposia will celebrate its 50th anniversary when the conference convenes in Phoenix, Ariz., on March 10–14, 2024. Since the first international conference in 1974, WMS has grown to nearly 3,000 attendees representing more than 30 countries. The conference is an open forum for the exchange of information and discussion of opportunities related to all aspects of radioactive waste and materials management. As a nonprofit organization, all proceeds from the WMS conference go toward providing education and information on global radioactive waste management.
If you head west out of Idaho Falls on U.S. Highway 20 and make your way across the Snake River Plain, it won’t be long before you’ll notice a silver dome in the distance to the north. One of the most recognizable structures in the history of nuclear energy, Experimental Breeder Reactor-II stands out from the desert landscape. The 890-square-mile site on which EBR-II is located is the former National Reactor Testing Station, now known as Idaho National Laboratory.
The Philippines generates none of its electricity from nuclear energy. Until recently, it was even without a functioning research and training reactor. The lack of a nuclear facility has led to a dearth of scientific expertise in nuclear science and nuclear engineering in this nation of roughly 117 million people. Twenty-nine-year-old Ronald Daryll E. Gatchalian is on a mission to change that.
The Department of Energy’s Office of Environmental Management is responsible for roughly 90 million gallons of radioactive liquid waste at Idaho National Laboratory, the Hanford Site in Washington state, and the Savannah River Site in South Carolina. About 900,000 gallons of waste are stored at INL, 56 million gallons at Hanford, and roughly 36 million at SRS. A further 400,000 gallons of waste from various operations are being stored at the Oak Ridge Site in Tennessee.

Over the past 50 years, the use of nuclear energy has avoided approximately 70 gigatons of carbon dioxide emissions globally and 24 gigatons in the United States.1 Although carbon dioxide is not being released into the atmosphere when generating energy from nuclear, the waste this energy form does produce must be managed and permanently isolated away from people and the environment.

Climate change presents a grave threat, demanding increasing reliance on low-carbon energy over the coming decades. Nuclear power today contributes half of U.S. low-carbon generation, and achievement of climate goals requires the continued operation of existing plants. But there are competitors for low-carbon energy, and nuclear’s further role remains uncertain. The National Academies of Sciences, Engineering, and Medicine (NASEM) conducted a study to explore the challenges that must be overcome for widespread new nuclear deployment.1 This article provides my summary of the study, highlighting and abbreviating some of its principal recommendations. Note that the italicized portions of the article are shortened versions of the recommendations in the report.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.
Researchers at Savannah River National Laboratory (SRNL), in concert with Lawrence Berkeley National Laboratory, Massachusetts Institute of Technology, Pacific Northwest National Laboratory, and Florida International University, are leading the Advanced Long-Term Environmental Monitoring Systems (ALTEMIS) project to move groundwater cleanup from a reactive process to a proactive process, while also reducing the cost of long-term monitoring and accelerating site closure.
The U.S. Army Corps of Engineers is safely cleaning up the former Maywood Chemical Works FUSRAP site in New Jersey.
It is the 1940s in Maywood, N.J. A new residential community has sprouted up, and the homeowners want to beautify their front lawns, so they go to a nearby property to gather some fresh topsoil. Little did they know that they’re helping to plant the seeds for one of the largest and most high-profile environmental cleanup projects in the nation.
Currently, the Nuclear Regulatory Commission is overseeing 17 nuclear power plants that are undergoing active decommissioning. For 10 of those plants, the NRC licenses have been transferred, either through sale or temporary transfer, from the plant owner and operator to a third party, nonutility company for decommissioning. To be profitable, those companies are decommissioning the nuclear plants as expediently as they safely can, while still protecting workers and the environment, using proprietary techniques and processes.
Among the typical bustle of outage activities at the Surry Power Station in Virginia during the fall of 2022, an unfamiliar sound broke through the commotion. Even with hearing protection in place, a faint whir thunk, whir thunk, whir thunk could be heard, announcing the arrival of the latest innovation in nuclear power. Dominion Energy, owner and operator of Surry, had combined new technologies from robotics company Boston Dynamics and radiation detection company Gamma Reality Inc. to provide radiological condition monitoring throughout the plant that could protect technicians from radiation exposure. The result? A quadruped robot with real-time 3D radiation mapping and data fusion capabilities.
Anyone involved in the nuclear power industry could tell you that the operation of nuclear power plants is a demanding and never-ending endeavor. Our machines are complex, our challenges are diverse, and our standards are unyielding. The truth is, however, many of us stay in this field because there’s something at the heart of what we do that makes it all worthwhile.
Operating costs for nuclear units have grown significantly since the start of the commercial nuclear power industry. For nuclear power generation to remain competitive, process efficiencies and innovations will need to be introduced. The challenge for any change is to improve the safe operation of the nuclear unit. An area of opportunity to reduce operating costs while improving operational safety is through upgraded fuel design and manufacturing. At Southern Nuclear, the pressurized water reactor fuel engineering team worked with Westinghouse to implement the PRIME fuel features, where simple improvements would yield safer operation and long-term cost-savings due to a more robust fuel design. Implementing the PRIME fuel ensures that the operator’s burden from fuel performance is minimized while keeping the reactor unit in a safe operating condition.

It’s late March 2023, and freshman state Rep. Stephanie Barnard (R., 8th Dist.) moves quickly through the halls of the capitol building in Olympia, Wash. She enters a room packed with state legislators—both Democrats and Republicans—who are waiting for a meeting to begin.
The event is part of the recently formed Nuclear Energy Caucus, and the featured speaker is Carol Browner, director of the Office of Energy and Climate Change Policy under President Obama and the administrator of the Environmental Protection Agency during the Clinton administration. The meeting is a success, with animated discussion following Browner’s address.
A couple of years ago, my wife and I were looking to purchase a new car. But just as we made that decision, major pricing inflation and supply constraints became an issue. So, we decided to wait. We also knew that we would need new tires before we could sell our current vehicle. Instead of buying the best quality (and expensive) tires, we got the much cheaper ones, knowing we would only use them for a brief period. Why invest in an asset that won’t be serving its purpose for you that much longer, right?

Do you remember the days when nuclear was a contractor’s dream? When craftworkers could work outages every fall and spring at a high wage and make enough to take summers off? When companies had to turn down craftworkers looking for outage work because there were more people than positions? Well, those days are far behind us. How many of us struggle every year to fill our outage billets for pipefitters, boilermakers, and electricians? How many of us see return rates of less than 50 percent for some sites?
Industrial growth and demand in the United States have skyrocketed over the past 10 years in no small part due to our ability to provide reliable and low-cost power. The Tennessee Valley region’s population is growing at three times the national average. Nashville is growing at the rate of one Chattanooga—that is, 180,000 people—every four years.
Maintenance can mean no more than keeping the status quo. But plant maintenance programs at U.S. nuclear power plants do that and then some. Even the programs are themselves maintained and improved—and so a long-lived nuclear fleet has improved with time. Read on.
A digital twin is a virtual replica of a real system or physical asset. It is a trusted data source containing vital information about an asset, which could include dimensions, relevant manufacturer information, operations history, and maintenance records. To realize the maximal benefit from a digital twin at a nuclear power plant, for example, it must evolve as the facility is designed, constructed, and operated. Some general attributes and the resulting benefits of a digital twin follow:
It integrates information to a single location | → | Ease of access |
It connects to the physical asset | → | Continuous monitoring |
It dynamically learns and updates | → | Evolves with the asset |
The American Nuclear Society is pleased to celebrate Mehdi Sarram on the 60th anniversary of his membership. He joined the Society in 1963 when he was an undergraduate in nuclear engineering at the University of Michigan and has since served the nuclear energy industry as a nuclear engineer, reactor operator, professor, and mentor. Over the years, Sarram has been active in several local ANS sections and has made remarkable contributions to the peaceful uses of nuclear energy, including bringing Iran’s first nuclear reactor to full power.
