Despite nuclear power producing 10 percent of energy globally, it seems sometimes that ours is a world in which nuclear does not exist. We all have our own lives, our own passions, and our own separate interests—each of which in turn can feel like a world of its own. For example, I competitively water ski, and rarely does nuclear engineering come up during water skiing tournaments. Nuclear science is a major part of my life and my world—but it is not the only piece. Many of my other worlds have no intersection with nuclear science.

One of my worlds is my involvement in the Miss America Organization. I previously have shared stories about my experience as Miss Wisconsin, including using my platform to talk about nuclear with various individuals. Part of this role was competing for Miss America 2023, a title and position I was honored to win on December 15, 2022.

The African continent is made up of 54 countries and can be broadly divided into North Africa and Sub-Saharan Africa. For global power, Africa is an emerging frontier that holds much promise and could potentially be a new sphere of influence. It has a larger land mass than India, China, the contiguous United States, and Eastern Europe combined, but it can be easy for those unfamiliar with the continent to underestimate its size, influence, and diversity. In the coming years, Africa will play a growing role in global economics and demographics.

Hosted by Waste Management Symposia, the annual Waste Management Conference is widely regarded as the premier international conference on the management of radioactive material and related topics. The theme of this year’s conference, being held February 26-March 3 at the Phoenix Convention Center in Arizona, is “Planning for the Future: Innovation, Transformation, Sustainability.” The featured country for 2023 is France, which will be represented by numerous panels, papers, posters, and exhibits demonstrating the country’s continuous innovation and pragmatism in the management of the nuclear fuel cycle. The featured Department of Energy Office of Environmental Management topic is “EM’s Transformation in Radioactive Liquid Tank Waste Management.”

Each year, the two best oral presentations/papers from the previous year’s conference are recognized. Honoring the highest-quality presentations, the American Nuclear Society and the American Society of Mechanical Engineers each present an award for best presentation/paper. The following are the abstracts for the best ANS and ASME papers of 2022. The full papers are available to 2023 WM Conference participants through the WM Symposia website, at wmsym.org.

The origins of the Nuclear Regulatory Commission’s robust international program date back to 1953, when President Eisenhower, in an address to the United Nations, promised to share U.S. nuclear expertise with the world. This commitment underpins our international programs today.

The NRC’s early focus was cooperating with countries operating U.S. reactor technology to leverage collective operating experience. But requests for assistance grew steadily, and the 1986 Chernobyl nuclear accident made clear that international assistance was vital for global safety. We helped promote development of independent regulators in the former Soviet Union, and in a 1994 report, the independent NRC Office of the Inspector General praised how the NRC assisted Ukraine in establishing laws, regulations, and enforcement capacity.

When it comes to managing nuclear waste, technology is transforming the way some of the most problematic waste is handled. The idea to transform nuclear waste into glass was developed back in the 1970s as a way to lock away the waste’s radioactive elements and prevent them from escaping. For more than 40 years, vitrification has been used for the immobilization of high-level radioactive waste in many countries around the world, including the United States.

As president of ANS, I am frequently asked, if it is the American Nuclear Society, why are you concerned with what is happening outside the United States? I usually start with a simple response: Although ANS is incorporated in the U.S., the Society has local and student sections as well as members in a number of other countries and is involved with key issues throughout the world. Although this is true—we have seven international sections and four international student sections, and about 10 percent of our membership is from other countries—it is only part of the story. From the very beginning, nuclear science and technology has been an international collaboration. The U.S. certainly can claim leadership in a lot of the advances in the research and industrial applications of our technology, but most of our advances have been based on active collaboration both within and across borders.

During my tenure, I have seen this firsthand. As travel has opened up throughout the world in the past year, I have visited the Latin American and French sections of ANS, as well as the University of Puerto Rico student section, and I have attended a number of ANS-sponsored technical meetings throughout the world.

The 1957 amendment to the Atomic Energy Act of 1954 established the Advisory Committee On Reactor Safeguards as a statutory committee with an independent advisory role and the responsibility to “review safety studies and facility license applications” and advise the U.S. Atomic Energy Commission “with regard to the hazards of proposed or existing reactor facilities and the adequacy of reactor safety standards.” With the enactment of the Energy Reorganization Act of 1974, the ACRS was assigned to the newly established Nuclear Regulatory Commission with its statutory requirements intact.

Used nuclear fuel and high-level radioactive wastes are by-products of nuclear energy production and other applications of nuclear technology, and the consensus approach to disposing of those wastes safely is to encapsulate them and emplace them in stable geologic formations (geologic repositories) where they will be isolated from people and the environment for very long periods of time. The federal government has established environmental standards for waste isolation that any proposed geologic repository must meet.

In July 2021, the American Nuclear Society established a special committee to consider possibilities for revised generic environmental standards for disposal of spent nuclear fuel and high-level radioactive waste in the United States. The committee developed a number of recommendations, which are contained in a draft report that was to be issued in February for review and comment by stakeholders. The draft report can be found on the ANS website, at ans.org/policy/repositorystandard/.

The committee’s draft recommendations are based on two underlying assumptions. First, that the relevant legislative framework for regulation defined in the Nuclear Waste Policy Act (NWPA) remains unchanged. Specifically, it is assumed that the Environmental Protection Agency will be charged with promulgating environmental standards for disposal and that the Nuclear Regulatory Commission will be charged with reviewing applications for disposal facilities using licensing requirements and criteria consistent with the EPA standards. Second, that existing generic disposal standards will be updated or replaced.

In March 1949, the Atomic Energy Commission selected a site in Idaho for the National Reactor Testing Station (NRTS), known today as Idaho National Laboratory. Idaho’s Snake River Plain was selected because of the rural nature of southern Idaho. The site would go on to be the most remarkable proving ground for today’s nuclear industry. Experiments at this world-class facility have continually paved the way for nuclear innovation.

In remote southeastern Washington you will find the sprawling Hanford Site, which was constructed to produce plutonium for the Manhattan Project. Within this complex is the first plutonium production reactor, the Hanford B Reactor. The DuPont Corporation was responsible for construction and operation of the B Reactor. Due to the urgency of the Manhattan Project, construction was completed in just over a year, and The B Reactor went critical on September 26, 1944. After the needs of the Manhattan Project were satisfied, the reactor was briefly shut down and then restarted to produce plutonium for roughly another 20 years, supporting Cold War efforts. In addition to plutonium production, the B Reactor also pioneered the process to produce tritium for the first-ever thermonuclear test.

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.

The Department of Energy’s commitment to breaking down market barriers with initiatives, programs, and access to facilities is making it simpler and more efficient than ever for industry to partner with national laboratories. It is especially timely, as the country continues to face evolving security, economic, and clean energy challenges. Partnering opportunities via the DOE’s Cooperative Research and Development Agreements (CRADAs) and Strategic Partnership Projects (SPPs) are particularly prevalent in the commercial nuclear community and have seen a tremendous amount of funding and support dedicated to advancing the development, demonstration, and deployment of new reactor technologies.

Say “decarbonize” and people think about electricity. But the U.S. industrial sector emits nearly as much carbon dioxide and other global warming gases as the electric sector, which rank at 25 and 24 percent of the problem, respectively, according to the U.S. Environmental Protection Agency. The commercial and residential sectors account for another 13 percent, the EPA says, most of it for space heating. How do we decarbonize that? More specifically, how do nuclear reactors decarbonize that?

In a former farm field just outside the historic town of Janesville in south-central Wisconsin, a large concrete-and-steel building is taking shape. Dubbed the Chrysalis, the building will eventually house eight accelerator-based neutron generators, which start-up company SHINE Technologies will use to produce molybdenum-99. As the precursor to the medical radioisotope technetium-99m, Mo-99 is used in tens of millions of diagnostic procedures every year, primarily as a radioactive tracer.

At the heart of the Chrysalis will be the high-flux neutron generators, being supplied by SHINE’s sister company, Phoenix. The compact accelerators use a deuterium-tritium fusion process to produce neutrons, which in turn induce a subcritical fission reaction in an aqueous low-enriched uranium target (19.75 percent uranium-235) to produce Mo-99.
