Westinghouse Parts Business (WPB) is proud of the first next generation Motor Generator (MG) Set System fully operational at Palo Verde Generating Station. The team completed a first-of-a-kind (FOAK) implementation and installation at the power plant operated by Arizona Public Service (APS), including the next generation MG Control Power Cabinets and new MG Sets. Additionally, Westinghouse installed the new ARCH (Advanced Rod Control Hybrid) system. These systems were installed in a single outage providing additional synergies and cost savings to operations.

Serving as the world’s first scalable nuclear power plant, Shippingport Atomic Power Station led the way for today’s nuclear generation fleet. Shippingport was centrally located roughly 25 miles from Pittsburgh, Pa., to provide electrical generation for many end-users. Shippingport also served as an experimental reactor that allowed engineers and designers the ability to test different core designs, and as such, the site housed additional testing equipment otherwise not commonly seen. The primary goal of Shippingport was always to generate electricity; however, its ability to function as an experimental reactor served utilities in further development of scalable nuclear generation.

Nuclear power is the single largest source of clean energy in the United States, but how can the value of “clean” be measured? Two recent reports by researchers at the Massachusetts Institute of Technology and Pacific Northwest National Laboratory, respectively, measured the clean energy benefits of nuclear energy in different ways: the benefits to human health from the air pollution avoided and the future economic value of avoided carbon emissions.

Earlier this year, the American Nuclear Society's newly formed Special Committee on Certification started conducting market research with the help of a third party contractor to determine the viability of a nuclear certification program. An initial survey was sent to the membership back in March with the goal of determining what certification programs were already available and what type of certification program ANS could develop to benefit the community.

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?”

Under the Radioisotope Power Systems Program, NASA and the Department of Energy have been advancing a novel radioisotope power system (RPS) based on dynamic energy conversion. This approach will manifest a dynamic RPS (DRPS) option with a conversion efficiency at least three times greater than a thermoelectric-based RPS. Significant progress has recently been made toward this end. A one-year system design phase has been completed by NASA industry partner Aerojet Rocketdyne, which resulted in a DRPS with power of 300 watts-electric (W_e) with convertor-level redundancy. In-house technology development at the NASA Glenn Research Center (GRC) has demonstrated the conversion devices in relevant environments and has shown all requirements can be met. Progress has also been made on the control electronics necessary for dynamic energy conversion. Flight-like controllers were recently upgraded and achieved an 11-percentage-point increase in efficiency. Control architectures have been developed to handle the multiconvertor arrangements in the latest DRPS design. A system-level DRPS testbed is currently being assembled that will experimentally demonstrate the DRPS concept being pursued.

DOWNERS GROVE, ILL – The American Nuclear Society (ANS) CEO and Executive Director Craig Piercy issued the following statement on the connection of Vogtle unit 3 to the grid:

Women including Marie Skłodowska-Curie, Lise Meitner, Chien-Shiung Wu, and Katharine Way were key pioneers in nuclear science and technology, but today the visibility of women in the nuclear sector remains low. Women make up just one-quarter of people employed in the nuclear sector, and for STEM positions in that field specifically, they make up just one-fifth of the workforce. About 8,000 of those women responded to an a survey from the OECD Nuclear Energy Agency, and their responses have been captured in Gender Balance in the Nuclear Sector, a new report from the OECD NEA.

Last year, American Nuclear Society volunteer leadership and ANS staff began the process of investigating the creation of a nuclear certification program to be developed and administered by ANS. Shortly after the Annual Meeting in June 2022, the Certification Committee, chaired by Rebecca Steinman, was formed. Members include ANS President Steven Arndt, Mary Lou Dunzik-Gougar, Chip Lagdon, Christina Leggett, John Mahoney, Craig Piercy, Catherine Prat, Alexandra Siwy, Tracy Stover, Josh Vajda, and Art Wharton.

Dow and X-energy announced today that they have signed a joint development agreement (JDA) to demonstrate the first grid-scale advanced nuclear reactor at an industrial site in North America within a decade. As part of the agreement, Dow is now a subawardee under X-energy’s Advanced Reactor Demonstration Program (ARDP) Cooperative Agreement with the Department of Energy.

LA GRANGE PARK, Illinois – Today, the American Nuclear Society (ANS) released draft recommendations on updating public health and safety standards for the permanent disposal of commercial used nuclear fuel and high-level radioactive waste at future geological repository projects in the United States. The draft report provides a recommended framework for revisiting U.S. Environmental Protection Agency (EPA) geologic repository standards.

The United Kingdom’s nuclear renaissance

The United Kingdom’s nuclear industry is expanding, with the U.K. government committed to supporting the build of more civil nuclear power plants (deployments up to 24 GW by 2050)¹ while also undertaking large-scale decommissioning work in parallel.² The defense sector is experiencing growth with the decommissioning, operation, and new build of submarines, plus managing the U.K.’s deterrent.³ Although the civil and defense programs are separate, they draw on the same group of skills and people.

In the 1960s, Alvin Weinberg at Oak Ridge National Laboratory initiated a series of studies on nuclear agro-­industrial complexes¹ to address the needs of the world’s growing population. Agriculture was a central component of these studies, as it must be. Much of the emphasis was on desalination of seawater to provide fresh water for irrigation of crops. Remarkable advances have lowered the cost of desalination to make that option viable in countries like Israel. Later studies² asked the question, are there sufficient minerals (potassium, phosphorous, copper, nickel, etc.) to enable a prosperous global society assuming sufficient nuclear energy? The answer was a qualified “yes,” with the caveat that mineral resources will limit some technological options. These studies were defined by the characteristic of looking across agricultural and industrial sectors to address multiple challenges using nuclear energy.

Next week will mark 25 years since January 31, 1998, a familiar date to most in the nuclear community, and revisited in today’s #ThrowbackThursday post with an article from the March 1998 issue of Nuclear News. “Those in the nuclear power industry are aware of the significance of the date January 31, 1998. ln the Nuclear Waste Policy Act of 1982, that date was set as the deadline for the U.S. government—more specifically, the Department of Energy—to begin taking possession of and responsibility for spent nuclear fuel from nuclear power plants nationwide” (NN, March 1998, p. 59).

Are you an energy genius? It’s hard to tell whether or not Americans are really aware of the energy that controls our lives, so the following quiz should be revealing. Click through the multiple-choice options below to reveal the answers.

Scoring: Zero to five correct answers out of the 23 questions means you may need to read up on energy so you’re not at the mercy of others. A score of 6 to 10 correct answers is a good passing grade. Answer 11 to 15 correctly, and you’re really energy literate. Getting 16 to 19 correct means you should be advising Congress. Twenty or more right answers suggests you’re Spock reincarnated.

In the 1960s, nuclear energy established itself as a mainstay of the electrical grid for its ability to produce carbon-­free, safe, and reliable power. Indeed, nuclear energy currently provides about 50 percent of carbon-­free electricity in the United States, but a major challenge is its cost.

Since the inception of commercial nuclear power in the United States, every control room in every nuclear plant has looked essentially the same. You will see fixed alarm tiles, red and green lights, rows of switches, and analog meters. Until about a decade ago, you would even have seen paper charts (now replaced by digital versions of those same charts). Licensed operators have shown through a proven operating history that this control room design is safe and effective. Genius definitely went into the complexity of circuits and placement of switches and indications in the design, but things have come a long way over the years, and new technology, updated plant designs, and the need to improve efficiency and maintain reliability have impacted staffing and the role of operators. A control room update is long overdue. So, what lies ahead for the future of nuclear control room design? What possibilities exist for the next generation of plants?

Meteorological winter is here, and a chill is gripping northern Europe. Predictably, renewable generation has entered a seasonal lull and heating demand is up, despite a push to conserve natural gas, which means electricity and gas bills are up too. With a grudging nod to reality, German chancellor Olaf Scholz ensured in October that Germany’s three remaining nuclear power reactors will provide a few more months of clean, reliable power. Their premature closure, once scheduled for December 31, is now expected by April 15, 2023.

Mobile unmanned systems, also known as MUS, encompass a range of robotic devices, including drones, ground vehicles, crawlers, and submersibles. They are used for a wide range of industrial and defense applications to automate operations and assist humans or completely remove human workers from hazardous conditions. Robotics are ubiquitous in industrial manufacturing. Military robots are routinely employed in combat support applications, such as reconnaissance, inspection, explosive ordnance disposal, and transportation. Drones are used in many industries for security and monitoring, to conduct aerial inspections or surveys, and to capture digital twins. Wind and solar farms use MUS technologies for day-to-day operations and maintenance.

Nuclear energy is no longer on the fringes of the international climate conversation. At COP27, the United Nations climate change conference held in Sharm el-Sheikh, Egypt, from November 6 to 18, pronuclear advocates were everywhere—and they were talking to everyone. They populated the International Atomic Energy Agency’s #Atoms4Climate pavilion, the first-ever nuclear pavilion in the 27-year history of the negotiations. Echoing such strong representation, the final statement issued by the conference used language that included nuclear power.
