Nuclear research reactors throughout the world enable crucial scientific progress that benefit many sectors, health care and the environment among them. But some of those reactors need an important adjustment: a conversion from using high-enriched uranium fuel to using low-enriched uranium fuel.
President Joe Biden and Prime Minister Fumio Kishida of Japan have announced the successful removal of more than 30 kilograms of high-enriched uranium from three Japanese sites to the United States. The news came in a May 23 statement from the Department of Energy’s National Nuclear Security Administration.
Savannah River National Laboratory has announced the establishment of the Nonproliferation Applied Sciences Center (NASC), to be located on the lab’s main campus at the Department of Energy’s Savannah River Site in Aiken, S.C. Tammy Taylor, associate laboratory director for global security, will lead the development of the center until a permanent director is selected later this year.

Plutonium from an International Atomic Energy Agency laboratory in Austria has been removed to the United States, the Department of Energy’s National Nuclear Security Administration announced on March 29.
The plutonium was shipped from the IAEA’s Nuclear Material Laboratory in Seibersdorf, Austria, to Oak Ridge National Laboratory in Tennessee, where it will be used in sealed sources for nonproliferation research and development.
Safeguards: The plutonium included in the shipment represents approximately 15 years of accumulated residue from inspection samples collected in support of the IAEA’s safeguards mission, according to the NNSA. Technical experts from ORNL and Savannah River National Laboratory worked with a team from the IAEA for several years to complete all activities required for the safe and secure transportation of the material to Oak Ridge.
The nonproliferation-related monitoring of nuclear reactor operations received a boost from a new study focusing on the use of seismic and acoustic data for such purposes, ScienceDaily reported last week. The study, conducted by investigators at Oak Ridge National Laboratory, was published March 9 in the journal Seismological Research Letters.
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.
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.
An expert panel will look back at the origins of the Nuclear Non-Proliferation Treaty (NPT) in an ANS webinar to be held on Monday, February 15, from 1 p.m. to 2:30 p.m. (EST). Register now for the webinar, “The Nuclear Non-Proliferation Treaty at 50 Years,” which is free and available to all members.

ANS remembers the life of George P. Shultz and mourns his passing. A nonproliferation hero and renowned statesman, Shultz leaves behind a legacy that will continue to inspire for generations to come.
As U.S. Secretary of State, Shultz was paramount in achieving a peaceful end to the Cold War and shepherding landmark arms control agreements with the Soviet Union, including the Intermediate Range Nuclear Forces Treaty of 1987.
The Nuclear Threat Initiative (NTI) and the Center for Advanced Defense Studies (C4ADS) last week released Signals in the Noise: Preventing Nuclear Proliferation with Machine Learning & Publicly Available Information, a 22-page report that provides a blueprint for identifying high-risk or illicit nuclear trade. (Machine learning can be defined as a branch of artificial intelligence focused on building applications that learn from data and improve their accuracy over time without being programmed to do so.)

The United States and Canada have signed a memorandum of understanding—Cooperation and Exchange of Information in Nuclear Security, Safeguards, and Nonproliferation Matters—to enable a more effective collaboration between the two countries in the areas of nuclear safety and security.
The five-year agreement was signed virtually on October 16 by Brent Park, the National Nuclear Security Administration’s deputy administrator for Defense Nuclear Nonproliferation, and two Atomic Energy of Canada Limited (AECL) executives: Richard Sexton, president and chief executive officer, and Shannon Quinn, vice president of Science, Technology, and Commercial Oversight.

U.S. civil nuclear cooperation pacts—so-called 123 Agreements—are too strict, says Michael Shellenberger, founder and president of Environmental Progress, in an August 13 City Journal article.
Shellenberger reasons that the 123 Agreements force nations that have expressed interest in developing nuclear energy programs to turn to Russia and China. That result is bad, Shellenberger continues, not only for the American nuclear industry, but also for the global nonproliferation movement.
The Nuclear Threat Initiative’s 2020 NTI Nuclear Security Index, released last week, finds that progress on the protection of nuclear materials and facilities has slowed significantly over the past two years, reversing a trend of substantial improvements between 2012 and 2018.
Published biennially since 2012, the NTI index assesses and tracks nuclear security conditions in countries around the globe, highlighting progress and trends over time. It is produced in cooperation with the Economist Intelligence Unit, the research and analysis division of the Economist Group media company.
IAEA Director General Grossi presented concerns to the agency’s board about Iran’s implementation of its nuclear-related commitments to the Joint Comprehensive Plan of Action.
Rafael Mariano Grossi, the International Atomic Energy Agency’s director general, called on Iran on March 9 to cooperate immediately and fully with the IAEA and to provide prompt access to locations that it has refused to let agency inspectors visit. “The agency has identified a number of questions related to possible undeclared nuclear material and nuclear-related activities at three locations that have not been declared by Iran,” Grossi said in his first address to the IAEA’s Board of Governors since being named director general in December.
