Public and private sectors are actively advancing research and development and concepts to realize a path to practical, clean, safe fusion energy. New fusion performance records continue to be set around the world, including at the National Ignition Facility (Lawrence Livermore National Laboratory), which demonstrated fusion ignition in 2022 and 2023.

However, significant obstacles for practical fusion remain. One challenge is to create and sustain a fusion power source. That is the mission of the international ITER project and the fundamental reason ITER is so valuable to the United States and the other ITER members (China, Europe, India, Japan, Korea, and Russia). Now under assembly in France, ITER is an experimental facility that will provide essential data and experience while also reducing risk for other fusion concepts. ITER will deliver unprecedented self-heated fusion performance, including fusion gain of up to 10 times greater power out of the plasma than the power into the plasma, fusion power of up to 500 megawatts, and long durations of hundreds to thousands of seconds.

The recent article “How Innovative Is China in Nuclear Power?” published by the Information Technology and Innovation Foundation (ITIF) describes how China has become the world’s leading proponent of nuclear energy. The reason, the article maintains, is because its nuclear industry has been “supported by a whole-of-government strategy that provides extensive financing and systemic coordination.”

Latest electricity cost estimates get new details on nuclear

July 1, 2024, 12:00PMNuclear News

Every year, the National Renewable Energy Laboratory (NREL) puts out a set of technology-specific cost and performance parameters for electricity generation. Now in its 10th year, the Electricity Annual Technology Baseline (ATB) has nearly 100,000 users from 144 countries, according to NREL. Utility planners and grid operators who look to the ATB to assess their investment options in a changing market require complete and accurate information and will be glad to know that the 2024 Electricity ATB, released June 24, includes—for the first time—a range of data on nuclear energy.

Thank you for the opportunity to serve as your American Nuclear Society president. The support from within the Society, academia, professional organizations, and international partners has been heartwarming. Students have expressed joy about what the future holds, and they are ready, as am I, to be part of keeping the industry moving forward.

The year 2001 was pivotal for me; it represented my start in nuclear engineering. My career has centered around precollege and university students. To be cliché, they are our future, and we must continue to support their maturation in the field and in ANS. My cup is full when students thrive, and the Society has made many gains in this arena. We have a robust K-12 STEM program that continues to be refined, and partners among educators and organizations that strengthen the routes into the discipline.

Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

With increasing demand for clean, reliable, and safe sources of energy, the conversation around nuclear energy is changing. And so too is the conversation around nuclear waste, even as the country struggles to find a path for the disposal of its spent nuclear fuel and high-level radioactive waste. From community engagement, to recycling, to existing success around other forms of nuclear waste management, the conversation around nuclear waste has many different angles, and an executive session of the American Nuclear Society’s 2024 Annual Conference in Las Vegas aimed to delve into some of those discussions.

Seabed mining for critical metals: A brilliant idea, or another environmental catastrophe?

Regardless of how you power our grid or how you attempt to decarbonize our economy, we will need many various metals to achieve any future, or even to just continue with business as usual. Critical metals like cobalt, lithium, nickel, and neodymium are essential to a low-carbon-energy future if renewables and electric vehicles are to play a large role.1 Even if nuclear provides 100 percent of our power, just operating the grid and electrifying most sectors will take huge amounts of critical metals like copper, notwithstanding the fact that nuclear power requires the least amount of metals and other materials of any energy source.

Researchers at the Department of Energy’s Oak Ridge National Laboratory want to make the sensors in nuclear power plants more accurate by linking them to electronics that can withstand the intense radiation inside a reactor. Electronics containing transistors made with gallium nitride, a wide-bandgap semiconductor, have been tested in the ionizing radiation environment of space. Now, according to a June 24 article from ORNL, tests carried out in the research reactor at Ohio State University indicate they could withstand neutron bombardment within a nuclear fission reactor.

It was a summer day in 1956 in Berkeley, Calif., when I, a freshly minted Ph.D., left Lawrence Livermore National Laboratory to travel to Pittsburgh, Pa., to join Westinghouse’s Commercial Atomic Power (CAPA) program. We were going to develop a large homogeneous power reactor—the future of energy. A year later, my efforts were diverted to lead what may have been one of the first nuclear safeguards equipment development programs funded by the Atomic Energy Commission.

Argonne National Laboratory’s thermal reactor program in Idaho

In May’s Nuclear News (p. 86), we reviewed Argonne National Laboratory’s comprehensive work on fast reactors in Idaho. In this article, we summarize the light water reactor work there.1

In the early days, there were few data on the behavior of reactor materials under severe neutron bombardment. In collaboration, Oak Ridge National Laboratory and Argonne National Laboratory developed the Materials Testing Reactor (MTR) for the National Reactor Testing Station (NRTS) in Idaho. The materials tested in it over the course of 15,000 experiments were reactor fuel materials, structures, cooling systems, and shields. It operated from 1952 to 1970.

How can SMRs revolutionize industrial decarbonization?

June 25, 2024, 12:04PMNuclear NewsJosé Reyes

José Reyes

Innovations with small modular reactors, which offer a compact, efficient alternative to traditional baseload power plants, are at the forefront of a new era of nuclear energy production that can reshape how we approach industrial decarbonization.

As global energy transition efforts progress, it is essential to examine the potential these advancements hold for reducing carbon emissions. Nuclear energy has long been recognized for its ability to generate vast amounts of electricity without emitting greenhouse gases. The introduction of SMR technology represents a pivotal shift, addressing many previous challenges to nuclear deployment and opening new pathways for the integration of nuclear energy into industrial sectors.

The innovative yet simple design of NuScale’s SMR technology provides a cost-competitive, safe, and scalable solution for a wide range of energy needs.

Political leader ignites nuclear energy controversy in Australia

Dutton

The only nuclear reactor in Australia is a small one in the Sydney suburb of Lucas Heights, which has been used to produce medical radioisotopes since 1958. Recently, the Hon. Peter Dutton, Parliament’s leader of the opposition to the Labor-led government, announced his plan to get the country into the nuclear energy business by building five large reactors and two small modular reactors by 2050.

Criticizing the government’s “renewables-only” energy policy, Dutton promised to have the first nuclear reactor operating by the mid-2030s, should his Liberal–National Coalition win power in the next federal election (to be held on or before September 27, 2025). That promise, which would require overturns of existing federal and state bans on nuclear energy, has generated a great deal of controversy in Australia among government officials, political activists, and nuclear engineers.
