International nuclear safeguards verification relies on a precise count of isotope particles collected on swipes during International Atomic Energy Agency inspections of nuclear facilities and isolated through a series of lengthy chemical separations that can take about 30 days to complete. On October 15, Oak Ridge National Laboratory—a member of the IAEA’s Network of Analytical Laboratories (NWAL)—announced that analytical chemists at the site have developed a faster way to measure isotopic ratios of uranium and plutonium collected on swipes, which could help IAEA analysts detect the presence of undeclared nuclear activities or material.

Using a specialized radiation detector, Department of Energy cleanup contractor UCOR is characterizing a hot cell at Oak Ridge National Laboratory in preparation for its demolition. The detector overlays a radiation-intensity color-map on a picture of the environment and identifies gamma-emitting nuclides and their locations.

Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.

The Transformational Challenge Reactor (TCR) program was launched in 2019 to demonstrate that highly improved, efficient systems can be created rapidly by harnessing the major advances in manufacturing, materials, and computational sciences that have emerged since the end of the first nuclear era. The Department of Energy’s Oak Ridge National Laboratory leads the TCR program, which includes contributing partners from other DOE national laboratories and the U.S. nuclear industry. The program leverages some of the nation’s leading scientists and engineers and draws from ORNL’s lengthy history, institutional knowledge, and capabilities in high--performance computing, materials science development, advanced manufacturing techniques, and nuclear science and engineering.

At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.

The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.

Weinberg

Alvin M. Weinberg, a founder, Fellow, and fifth president (1959–1960) of the American Nuclear Society, was a Manhattan Project physicist who studied at the University of Chicago before building a celebrated career in Oak Ridge, Tenn., where he influenced the development of peaceful uses of nuclear energy in the United States. Weinberg’s personal files tell the story of his decades of work in Oak Ridge from the 1940s to the 1980s, and the Alvin Weinberg Archive Project was created to digitize the archive, ensuring that it would be accessible to researchers and the public.

A place in time: Weinberg arrived in Oak Ridge, Tenn., in 1945, and soon became head of the Physics Division of Clinton Laboratories. In 1948, the laboratory was renamed Oak Ridge National Laboratory, and Weinberg was appointed director of research, a role he held until 1955, when he was named laboratory director. In 1974, Weinberg moved 17 file cabinets from ORNL to Oak Ridge Associated Universities (ORAU), where he founded the Institute for Energy Analysis (IEA) and served as its director until his retirement in 1985. Under Weinberg’s guidance, the IEA studied atmospheric carbon dioxide and its effect on global warming, as well as alternative energy sources.

An Oak Ridge National Laboratory researcher has built a device that can speed up the separation of the medical radioisotope actinium-225 from irradiated thorium targets and withstand the high-radiation environment of a hot cell. In July, ORNL announced that Kevin Gaddis, a chemistry technician at the lab, had built and tested a prototype and was working to secure a patent for a device that cut separations time by 75 percent.

Several lead test rods of Westinghouse’s EnCore accident tolerant fuel recently arrived at Oak Ridge National Laboratory for post-irradiation examination over the next year in support of the Nuclear Regulatory Commission’s licensing process. The rods were installed in 2019 in Exelon’s Byron-2, a 1,158-MWe pressurized water reactor, and were removed in fall 2020 and prepared for shipment to ORNL.

Molten salt reactor technology first gained popularity in the 1960s, through the Molten Salt Reactor Experiment program at Oak Ridge National Laboratory. Now, decades later, a technology known as the molten salt nuclear battery (MsNB) is being developed to support the growing need for carbon-free, reliable, independent, and compact sources of small-scale heat and electrical power.
