Research & Applications

Oak Ridge National Laboratory has a long record of advancing fusion and fission science and technology. Today, the lab is focused more than ever on taking advantage of that spectrum of nuclear experience to accelerate a viable path to fusion energy and to speed efficient deployment of advanced nuclear technologies to today’s power plants and future fission systems.

The definition of a microreactor is ambiguous. But whether your upper cutoff is 10 MW or 20 MW, the Microreactor Applications Research Validation and Evaluation (MARVEL) reactor that the Department of Energy plans to build is, at 100 kW, on the tiny side of micro.

The Nuclear Regulatory Commission has sent to Congress its annual report on abnormal occurrences involving the medical and industrial uses of radioactive material. An abnormal occurrence is defined by law as an unscheduled incident or event that the NRC determines to be significant from the standpoint of public health or safety. The NRC sets specific criteria, most recently updated in October 2017, for determining which events qualify.

As governments around the world cooperate on the ITER tokamak and, in parallel, race each other and private companies to develop commercial fusion power concepts, it seems that “game-changing” developments are proclaimed almost weekly. Recently, the United Kingdom and China announced new fusion program results.

U.S. energy secretary Jennifer Granholm and French minister for the ecological transition Barbara Pompili issued a joint statement on May 28 in which they pledged to work together to meet shared climate goals.

“France and the United States share common goals and common resolve in fighting climate change and working toward reaching the ambitious target set forth by the Paris agreement,” the statement read. “We are united in a common ambition on both sides of the Atlantic: achieving net-zero carbon emissions by 2050. Reaching this common objective will require leveraging all currently existing emission-free technologies available to us while simultaneously intensifying research, development, and deployment across a suite of zero-emissions energy sources and systems. Ensuring that these energy systems are efficient and reliable, integrating larger shares of renewables coupled with nuclear energy, which is a significant part of today’s electricity production in both our countries, will be crucial to accelerate energy transitions. Reaching this common objective will also require a wide variety of favorable financing conditions across the range of zero-emitting power sources and systems.”

The Department of Energy is providing up to $2 million in fiscal year 2022 to fund university and national laboratory studies into the use of novel, medically relevant isotopes for use in pre-clinical and clinical medical trials, the DOE’s Office of Science announced on June 1.

Operators at the Advanced Test Reactor at Idaho National Laboratory have begun a nine-month outage to perform a core internals changeout. When the ATR is restarted in early 2022, the top head closure plate of the pressurized water test reactor will have new access points that could permit the irradiation of more fuel and material samples in the reactor’s high-flux neutron conditions.

The Advanced Test Reactor (ATR) at Idaho National Laboratory is getting an overhaul that will keep it off line for nine months. When the ATR is restarted in early 2022, the one-of-a-kind pressurized water test reactor—which is operated at low pressures and temperatures as a neutron source—will be ready for another decade or more of service, with the potential for more experimental capacity in years to come.

The International Atomic Energy Agency has created a new program, NUclear TEChnology for Controlling Plastic Pollution (NUTEC Plastics), to address the global environmental impact of plastic pollution in oceans. It uses nuclear technology to monitor pollution and also to decrease the volume of plastic waste by using irradiation to complement traditional plastic recycling methods.

SHINE Medical Technologies plans to locate its European medical isotope production facility in the Netherlands after a yearlong search and a review of more than 50 proposals from sites across Europe. The company announced on May 20 that construction at the site should begin in 2023 with commercial production starting in late 2025.

The Department of Energy has announced up to $40 million in funding for a new Advanced Research Projects Agency-Energy (ARPA-E) program to conduct research and development into technologies for reprocessing and ultimately disposing of used nuclear fuel. The program, “Optimizing Nuclear Waste and Advanced Reactor Disposal Systems” (ONWARDS), announced on May 19, targets both open (once-through) and closed (reprocessing) fuel cycles to reduce the amount of waste produced from advanced reactors tenfold when compared to light water reactors.

Nonproliferation, safeguards, and security were on the agenda for the fifth public information-gathering meeting of the National Academies’ Committee on Merits and Viability of Different Nuclear Fuel Cycles and Technology Options and the Waste Aspects of Advanced Nuclear Reactors. Moderated by committee chair Janice Dunn Lee and NAS study director Charles Ferguson, the two-day public meeting was convened on May 17 and was to be followed by a closed committee session on May 19.

The world’s first atomic bomb test—code-named Trinity and conducted in New Mexico on July 16, 1945—had an unintended outcome that was only recently discovered.

Help ANS celebrate the launch of our newest virtual field trip, “Nuclear Frontiers: Powering Possibility,” by attending tomorrow's online watch party!

The virtual field trip explores the amazing ways that nuclear science is fueling earthly innovation and deep space exploration. The field trip video, which was made available earlier this month, is part of ANS’s Navigating Nuclear: Energizing Our World program The Navigating Nuclear program, which was started in August 2018, has already reached more than 1.5 million K-12 students.

Register now for the watch party for the virtual field trip, to be held tomorrow, May 19, from 1 p.m. to 2 p.m. (EDT).

The Nuclear Regulatory Commission has approved a request by SHINE Medical Technologies for an exemption from regulations on how commercial grade equipment is defined, allowing the company to more easily procure components for the medical isotope production facility it is building in Janesville, Wis.

Traces of freshly made plutonium and radioactive iron recovered from the bottom of the Pacific Ocean are contributing to an understanding of how heavier elements are created from exploding stars and other cosmic events, according to a National Public Radio report.

Inside a new steel-clad facility nicknamed “The Citadel,” First Light Fusion has installed a 22-meter two-stage gas gun—the third-largest such component in Europe.

The National Reactor Innovation Center (NRIC) wants to hear from developers and end users interested in integrated energy systems for advanced reactors. Battelle Energy Alliance (BEA), the managing and operating contractor for Idaho National Laboratory, has issued a call for Expressions of Interest for a potential multi-phase demonstration program for innovative uses of nuclear energy, to be carried out by NRIC and the Crosscutting Technology Development Integrated Energy Systems (CTD IES) program. The final date for responses is May 21.
