Researchers have been working frantically to develop an array of materials and fibers to economically extract uranium from seawater—and they have succeeded. PNNL scientists exposed this special uranium-sorbing fiber developed at ORNL to Pseudomonas fluorescens and used the Advanced Photon Source at Argonne National Laboratory to create a 3-D X-ray microtomograph to determine microstructure and the effects of interactions with organisms and seawater.

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?

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 tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it.”
Many in the nuclear community are familiar with this sentiment from Admiral Rickover. A generation of stagnation in the industry has underscored the truth of his words. But as economies around the world put a price on carbon emissions, there’s a renewed sense of urgency to deploy clean energy technologies. This shifts the global balance of economic competitiveness, and it’s clear that the best path forward for nuclear requires combining the agility of private innovators with the technology and capabilities of national laboratories.

Small modular reactor developer ARC Clean Technology, Canadian utility New Brunswick Power, and nuclear plant operator Korea Hydro & Nuclear Power have signed a memorandum of understanding to explore opportunities for commercializing ARC technology in Canada, South Korea, and the United States, as well as in other regions where KHNP has business operations.

The development of modern nuclear reactor technologies relies heavily on complex software codes and computer simulations to support the design, construction, and testing of physical hardware systems. These tools allow for rigorous testing of theory and thorough verification of design under various use or transient power scenarios.

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.

A study published recently in the American Physical Society journal Physical Review C reveals new findings about the strong nuclear force, the mysterious fundamental force that holds together the protons and neutrons of the atomic nucleus. Experiments conducted at Argonne National Laboratory have shown how the round, heavy nuclei of the nickel-64 isotope (containing 28 protons and 36 neutrons, making it the heaviest stable Ni isotope) changed into one of two shapes—either like a doorknob or a football—depending on the amount of energy exerted on it. A summary of the research on the Phys.org website compares the nuclei shape change to popcorn kernels changing shape when heated in a microwave.
On December 2, 1942, a group of 49 scientists led by Enrico Fermi created the world’s first controlled, self-sustaining nuclear chain reaction underneath the University of Chicago’s Stagg Field football stadium. Some of those present went on to found Argonne National Laboratory. (Image: Argonne)
At a moment of global crisis, in a windowless squash court below the football stadium bleachers at the University of Chicago, a group of scientists changed the world forever.
On December 2, 1942, a team of researchers led by Enrico Fermi, an Italian refugee, successfully achieved the world’s first human-created, self-sustaining nuclear chain reaction. Racing to beat Nazi Germany to the creation of an atomic weapon, the team of researchers, working as part of the Manhattan Project, split uranium atoms contained within a large graphite pile—Chicago Pile-1, the first nuclear reactor ever built.

The Thermal Hydraulic Experimental Test Article (THETA) at Argonne National Laboratory is now operating and providing data that could support the licensing of liquid-metal fast reactor designs by validating thermal-hydraulic and safety analysis codes. The new equipment has been installed in Argonne’s Mechanisms Engineering Test Loop (METL), and its first experiments are supporting data validation needs of Oklo, Inc., by simulating normal operating conditions as well as protected and unprotected loss-of-flow accidents in a sodium-cooled fast reactor.

Exelon Generation has received a grant from the Department of Energy to explore the potential benefits of on-site hydrogen production and has chosen its Nine Mile Point nuclear power plant as the demonstration site, the company announced on Wednesday. (In 2019, Exelon received a conditional commitment from the DOE to co-fund a hydrogen electrolyzer demonstration at a nuclear plant.) Located in Scriba, N.Y., Nine Mile Point consists of two boiling water reactors—the 620-MWe Unit 1 and the 1,287-MWe Unit 2.

Seventy-five years ago today, on July 1, 1946, the first U.S. national laboratory was chartered with the singular mission of developing the peaceful uses of nuclear energy. Now, the Department of Energy’s Argonne National Laboratory is one of the nation’s largest science laboratories, working on diverse challenges in energy, climate, science, medicine, and national security.
