One of the biggest challenges in the nuclear community identified by ANS in 2017 is the continuous availability of radioisotopes. Working to meet that challenge is the ANS-led Source Security Working Group (SSWG), an alliance of industry sectors—including energy, health care, and industrial radiography—that seeks to ensure continued access to radiological sources. The SSWG serves as a strong voice to protect the continued availability of radiological sources, ensuring that laws and policies are risk informed, science based, and support the highest levels of public health and safety.

It has always amazed me how broad and diverse the nuclear science and technology field is. It is one of the things that drew me to the nuclear business in the first place. The American Nuclear Society, with its eighteen technical divisions, embraces this diversity from accelerator applications and space nuclear to isotopes and robotics. We are truly a disparate group of engineers and scientists. Based on this, I guess I should not be surprised by the renewed interest we are seeing in uses of nuclear energy beyond the generation of electricity. In recent years, engineers and scientists from all around the world have focused on reducing the impact of electric energy generation on the environment and on finding ways to also reduce the impact of other industrial processes. What I have been seeing—including at COP27—is a renewed interest in nuclear power not only for electric generation but also for its unique capabilities in a diverse set of applications. To name only a few, I have seen strong interest in desalinization, hydrogen generation, process heat, and district heat.

The Department of Energy held a groundbreaking ceremony on October 24 for the Stable Isotope Production and Research Center (SIPRC) at Oak Ridge National Laboratory in Tennessee. The center is being built to expand the nation’s capability to enrich stable isotopes for medical, industrial, and research applications.

Michigan State University’s Facility for Rare Isotope Beams (FRIB) officially opened yesterday with a ribbon-cutting ceremony attended by Energy Secretary Jennifer Granholm, elected officials, and guests who had supported the project during its planning and construction, including ANS Executive Director/Chief Executive Officer Craig Piercy. They were there to celebrate the completion—on time and within budget—of the world’s most powerful heavy-ion accelerator and the first accelerator-based Department of Energy Office of Science user facility located on a university campus.

This month’s issue of Nuclear News highlights the contributions of university-based programs in advancing nuclear science and technology and preparing the next-generation nuclear workforce.

In addition to the scholarly work they do, our university programs increasingly serve as an important public-facing component of the U.S. nuclear enterprise.

When you think about it, a lot of what goes on with nuclear happens within a security perimeter—“behind the fence,” if you will. Obviously, this is by necessity, as the technology involved is inherently sensitive. However, because the “magic” of nuclear remains out of view, something will always get lost in translation to the public. Yes, tours of commercial nuclear plants are still available to the interested and enterprising, but there is nothing quite like staring down into the core of a university TRIGA reactor and seeing the Cherenkov glow to stoke a person’s imagination.

The ANS Fuel Cycle and Waste Management Division will present a webinar today at noon EST (the recording will be available via the webinar archive to all ANS members) featuring an international panel of experts on nuclear waste reprocessing. The panel will explore the idea of separating certain radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.

ANS will host the webinar “Creating Value from Waste: Recycling Valuable Isotopes & Surplus Energy” on Thursday, January 27, starting at noon EST.

Early in my year as ANS vice president/president-elect, I was determined to try to find a project that the entire ANS community could rally behind and could be completed during my year as ANS president. I was looking for something that would provide community-identified focus areas for future activities and that would mobilize, energize, and inspire ANS members during that year and in the years ahead.

Laurentis Energy Partners, a subsidiary of Ontario Power Generation (OPG), has launched a new program to produce helium-3. The He-3 will be obtained from tritium stored at OPG’s Darlington nuclear power plant, a four-unit CANDU station located about 100 kilometers east of Toronto.

Darlington houses one of the world’s largest reserves of tritium, which is a by-product of the heavy water used in CANDU reactors.

Physicists from the Massachusetts Institute of Technology and other institutions have measured the effect of a single neutron in a molecule of radium monofluoride and hypothesize that radioactive molecules could be used as a tool to explore why there is more matter than antimatter in the universe. The research team’s findings were published in the journal Physical Review Letters on July 7, and on the same day, an article published online by MIT News explained the implications of their work.

Is isotope science all sweetness and light? Recent headlines on research confirming the sweet taste of heavy water and the creation of the lightest isotope of uranium yet may give that impression. But the serious science behind these separate research findings has implications for human health and for the understanding of the process of alpha decay.

The future of nuclear technology is bright and affords ample opportunities for today’s students to make an impact. That was the message given by the three plenary panelists on Saturday, April 10, during the final day of the 2021 ANS Virtual Student Conference. The three-day event was hosted by North Carolina State University and had nearly 500 registered attendees.

While scientists can tag migrating birds, mammals, and other animals to track their movements, the precise migration patterns of butterflies and other insects too small for tagging evaded scientists’ scrutiny for decades. That changed in 1996, when Leonard Wassenaar and Keith Hobson, working at the time as isotope scientists for Environment Canada, demonstrated that isotopic techniques could be used to determine the origin of individual monarch butterflies and deduce the species’ annual migration routes. Now, the same technique is being used to study other butterfly species.

A method developed at Oak Ridge National Laboratory is allowing the Department of Energy to cull promethium-147 from plutonium-238 produced for space exploration. Under an ORNL project for the DOE Isotope Program that began last year, the lab has been mining Pm-147, a rare isotope used in nuclear batteries and to measure the thickness of materials, from the fission products left when Pu-238 is separated out of neptunium-237 targets. The Np-237 targets are irradiated in Oak Ridge’s High Flux Isotope Reactor, a DOE Office of Science user facility, to produce the Pu-238.

According to the DOE, the primary goal of the project is to reestablish the domestic production of Pm-147, which is in short supply. As a side benefit, the project is reducing the concentrations of radioactive elements in the waste so that it can be disposed of safely in simpler, less expensive ways, both now and in the future.

“In the process of recovering a valuable product that the DOE Isotope Program wants, we realized we can reduce our disposal costs,” said Richard Mayes, group leader for ORNL’s Emerging Isotope Research. “There’s some synergy.”

The Monday session “Advancement in Medical Isotopes Production and Applications” of the 2020 ANS Virtual Winter Meeting was sponsored by the Isotopes & Radiation Division and co-chaired by Lin-Wen Hu of Massachusetts Institute of Technology and James Bowen of Pacific Northwest National Laboratory.

Radioisotopes produced from nuclear reactors and accelerators are widely used for medical diagnostics and cancer therapy. Technetium-99m (decay product of molybdenum-99), for example, is used in more than 80 percent of nuclear medicine diagnostic procedures. The session featured speakers who discussed the advancement and status of domestic production and applications of medical isotopes.

The Department of Energy is awarding up to $16 million in new funding to advance research and development of isotope production. The funding opportunity is part of a federal program that produces critical isotopes that are otherwise unavailable or in short supply for U.S. science, medicine, and industry. The effort is aimed at sustaining longstanding U.S. leadership in the vital field of isotope production, research, and development, according to the DOE.
