Data from the African Development Bank shows that Africans have an electricity access rate of 40 percent—the lowest in the world. This statistic is one I have been hoping to bring more awareness to and positively impact. Since stepping into my role at the Department of Energy’s Office of Nuclear Energy, I have prioritized focusing on Africa, leveraging the opportunity to deepen existing relationships and forge new ones.

Developments in advanced reactor technology are opening the door to all nations and promise to be critical to attaining climate and energy security goals. As we engage various countries on the African continent regarding their desire to pursue nuclear as an important part of their energy mix, Ghana has emerged as a nation that offers a unique partner profile that is aligned with our mission to support emerging markets and build regional leaders while also being motivated by its own sense of urgency in deploying new nuclear.

The development of nuclear power is one of the pillars of Poland’s energy transition, which involves construction of safe and modern Generation III+ pressurized water reactors.

Polskie Elektrownie Ja˛drowe (PEJ) is the company responsible for, among other things, preparing the investment process for the construction of the first Polish nuclear power plant with a capacity of up to 3,750 MWe. PEJ’s goal is to build six nuclear reactors (for a total capacity of 6–9 GWe), securing 25 percent of the electricity needed in Poland by 2043 and guaranteeing a stable supply of clean energy to millions of homes across the country.

The revitalization of nuclear energy policy in Japan began on August 24, 2022, with Prime Minister Kishida’s address at the second Green Transformation (GX) Executive Meeting. He said, “It is urgent to resolve the present deadlock in energy policy; in order to overcome the current crisis in power supply and demand . . . we will take all possible measures to prepare for unforeseen circumstances. In particular, regarding nuclear power plants (NPPs), the government will take all possible measures to restart the suspended NPPs already licensed for operation.” Kishida emphasized that nuclear power is an indispensable decarbonized energy source for the advancement of the green transformation. The cabinet in February 2023 approved the Basic Policy for the Realization of GX (hereinafter referred to as the GX Basic Policy).

After decades of false starts, U-turns, and stasis, the United States has arrived at a de facto solution for its high-level nuclear waste: Leave it in storage where it was produced, no matter how many tens of billions of dollars it costs, what impediments it raises for nuclear expansion, or what burdens it creates for the reuse of old reactor sites.

Dumb as it sounds, this is keeping all the major players happy. And it avoids alternative pathways, each of which has problems.

The Nuclear Engineering Department Heads Organization (NEDHO) has been sponsoring Diversity Panels since October 2022, when the inaugural meeting was hosted by the University of Tennessee Department of Nuclear Engineering. The panels were established as a distinguished speaker series by a working group led by Wes Hines, head of the UT Department of Nuclear Engineering, and Todd Allen, a former NEDHO chair and the current chair of the Department of Nuclear Engineering and Radiological Sciences (NERS) at the University of Michigan.

Allen explained that the panels are meant to be “a first step toward improving the diversity of the talent entering the nuclear science and engineering fields.” The idea came from a presentation by Andreas Enqvist, director of the nuclear engineering program at the University of Florida, at the November 2021 NEDHO meeting. According to Allen, Enqvist described “ASEE [American Society for Engineering Education] data on how poorly the nuclear engineering field was doing at getting black students to study nuclear at the B.S. level and, even worse, how few moved from B.S. to graduate programs.”

The year 2024 is shaping up to be a historic one for Posiva, the waste management organization owned by Finland’s two nuclear power plant utilities, Fortum and Teollisuuden Voima. The company is looking to receive regulatory approval of its operating license for the Onkalo deep geological repository for high-level radioactive waste by the end of the year.

For many Americans, the word “radiation” is often associated with fear of the unknown, yet the medical and scientific reality is that radiation is ever present in nature and is beneficial to human life. The truth behind radiation historically has been distorted and stigmatized—even the U.S. Nuclear Regulatory Commission recognizes that “radiation is naturally present in our environment, as it has been since before the birth of this planet.”

To embrace a responsible, low-carbon energy future, the American public should be aware of the beneficial applications of radiation instead of fearing it due to unsubstantiated hysteria generated by opponents of responsible nuclear energy.

In February 1957, construction was completed on the Sodium Reactor Experiment (SRE), a sodium-cooled, graphite-moderated reactor with an output of 20 MWt. The design of theSRE had begun three years earlier in 1954, and construction started in April 1955. On April 25, 1957, the reactor reached criticality, and the SRE operated until February 1964.

America, Japan, and China are racing to be the first nation to make nuclear energy completely renewable. The hurdle is making it economical to extract uranium from seawater, because the amount of uranium in seawater is truly inexhaustible.

While America had been in the lead with technological breakthroughs from the Department of Energy’s Pacific Northwest and Oak Ridge National Laboratories, researchers at Northeast Normal University in China have sprung ahead. But these breakthroughs from both countries have brought the removal of uranium from seawater within economic reach. The only question is when will the source of uranium for our nuclear power plants change from mined ore to sea­water extraction?

On August 2, 1946, 1 millicurie of the isotope carbon-14 left Oak Ridge National Laboratory, bound for the Barnard Free Skin and Cancer Hospital in St. Louis, Mo.

That tiny amount of the radioisotope was purchased by the hospital for use in cancer studies. And it heralded a new peacetime mission for ORNL, built just a few years earlier for the production of plutonium from uranium for the Manhattan Project.

The roles of nuclear energy as a clean energy source and in space exploration were highlighted at the recent Atoms for Humanity symposium, held October 25–26, 2023. The symposium, which was organized by Purdue’s Center for Intelligent Energy Systems (CiENS) and hosted by the university’s School of Nuclear Engineering, was held on the West Lafayette, Ind., campus in Eliza Fowler Hall.

The American Nuclear Society President’s Special Committee on Certification is making progress toward launching a nuclear certification program later this year. The program outlined to the ANS Board of Directors in 2023 is being designed to help establish industry standards and bridge workforce gaps in the nuclear sector to address the growing demand for qualified professionals in the nuclear industry.

According to the Council on Radionuclides and Radiopharmaceuticals, more than 82,000 nuclear imaging procedures using nuclear medicine are performed throughout the world every day. To administer these vital medical procedures, radiopharmaceutical companies and hospitals rely on a handful of producers of medical radioisotopes.

The adage “a rising tide raises all boats” keeps coming to my mind whenever I think about the work ahead for small modular reactor and advanced reactor development companies. The groundwork being laid by the entire industry is key to moving the whole group forward together. The drive to construct new nuclear will need to include all sizes, designs, and companies, because unlike in many industries, there is no way there can only be one “winner” if we are to meet climate goals.

Recently, at global climate summit COP28, a large portion of the international community announced a joint aim to triple worldwide nuclear power generation by 2050. This is tremendous news and a huge step in the right direction for many reactor developers. It means that the work developers are doing now will lead to a market for their product for years to come. The questions we must all be asking are “How do we get there?” “Who is going to take the leap of faith to build the first-of-a-kind designs?” and “What challenges lie ahead?”

Designs for high-tech products, and the start-ups that offer them, will always outnumber the commercial successes. Ditto: many more power plants are proposed than actually get built, no matter what the technology.

This is an axiom of free-market economies, but in early November 2023 it became painfully obvious in the advanced reactor field. NuScale Power, the only advanced reactor that has made it through the licensing gauntlet, acknowledged that the consortium of utilities that was its intended launch customer had failed to put together a feasible package.

This article is the first in a series that will examine the history of small modular reactors.

Small and medium reactors have been an integral part of the U.S. nuclear power enterprise since the early days of the industry. Many of the designs for the next generation of reactors are rooted in the designs of the 1950s and ’60s, but the development and push for deployment have gained momentum only within the last decade.

This recent momentum led a reader of Nuclear News to suggest an article reviewing the history of small modular reactors. NN staff jumped on this idea, deciding a series of articles would do better justice to such a complex and interesting topic.

Joseph Hendrie, Brookhaven National Laboratory physicist, NRC chair, and ANS past president (1984–1985), passed away in his home in Bellport, N.Y., on December 26 at the age of 98.

Hendrie, an American Nuclear Society member since 1956, was a leader in the nuclear community for much of his 45 years in nuclear reactor safety research. He served as the deputy director for technical review of the Atomic Energy Commission’s Directorate of Licensing from 1972 to 1974 and then was appointed chair of the NRC in 1977 (serving a second stint as chair in 1981—the only person to serve two nonconsecutive terms in that role).
