Radioactive materials are used in medical, research, and commercial facilities to treat cancer, irradiate blood, sterilize food and equipment, and build economies worldwide. In the wrong hands, however, even a small amount of radioactive material can do a great deal of harm. A radiological dispersal device (RDD), otherwise known as a “dirty bomb,” is believed to be an attractive weapon for terrorist groups due to its scale of impact—panic, physical contamination, costly remediation, and denial of access to facilities and locations.

The Department of Energy’s National Nuclear Security Administration Office of Radiological Security (ORS) enhances global security by preventing high-activity radioactive materials from being used in acts of terrorism. ORS implements its mission through three strategies: protecting radioactive sources used for vital medical, research, and commercial purposes by securing facilities that utilize radioactive isotopes; removing and disposing of disused sources; and encouraging the adoption and development of nonradioisotopic alternative technologies such as X-ray and electron beam irradiators.

New reports allege Russia is flying kamikaze drones and firing small arms near the site of Ukraine’s Zaporizhzhia nuclear power plant. Europe’s largest such facility, Zaporizhzhia has been under Russian control since 2022.

A recent drone attack at Ukraine’s Zaporizhzhia nuclear power plant prompted an emergency meeting by the International Atomic Energy Agency Board of Governors, during which the agency again called for the immediate removal of Russian military and personnel from the site.

Ukraine’s Zaporizhzhia nuclear power plant lost the connection to its only remaining backup power line last Thursday amid renewed indications of military activity in the area, the International Atomic Energy Agency reported.

I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.

Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.

The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

Contracts valued up to a combined $1 billion have been awarded by the National Nuclear Security Administration’s Office of Nuclear Smuggling Detection and Deterrence to SeaTech Global Security Solutions of Richland, Wash., and Parsons Government Services International Inc. of Pasadena, Calif.

International Atomic Energy Agency director general Rafael Mariano Grossi visited Russia this week to discuss the “future operational status” of Ukraine’s Zaporizhzhia nuclear power plant with Russian president Vladimir Putin.

U.S. officials have brought charges of nuclear materials trafficking against a Japanese gangster who has been in federal custody since 2022.

In a case filled with international espionage, along with alleged weapons and drug trafficking, Takeshi Ebisawa has been charged with attempting to sell uranium and weapons-grade plutonium. The 60-year-old Japanese national—who is believed to be a leading figure in the Yakuza, the Japanese organized crime syndicate—faces a long list of federal charges that carry sentence of life in prison.

Russian shelling is being blamed for damage to the single remaining power source to Ukraine’s Zaporizhzhia nuclear power plant, located on the front lines of the ongoing military conflict.

“After another attack by the Russians, the line that provided the energy supply to the Zaporizhzhia nuclear station was damaged,” Ukraine's power grid operator Ukrenergo said in a February 21 statement.

Recent staff cuts at Ukraine’s Zaporizhzhia nuclear power plant (ZNPP) are raising concerns among international nuclear watchdogs.

Ahead of his visit to the plant on February 7, International Atomic Energy Agency director general Rafael Mariano Grossi told the Associated Press that he will focus on the impact of personnel reductions, especially while Russia has denied access to employees of Ukraine’s nuclear operator, Energoatom.

The Department of Energy’s National Nuclear Security Administration hopes to dispose of up to 34 metric tons of surplus defense-related plutonium at the Waste Isolation Pilot Plant in New Mexico using a “dilute-and-dispose” strategy.

Recent observations have indicated that warm water has been discharged near the light water reactor at the Yongbyon Nuclear Scientific Research Center in North Korea, which is consistent with the purported commissioning of the LWR—a process that takes time for any new reactor—and suggests that the reactor has now reached criticality.

“The LWR, like any nuclear reactor, can produce plutonium in its irradiated fuel, which can be separated during reprocessing, so this is cause for concern,” said Rafael Mariano Grossi, director general of the International Atomic Energy Agency. “It remains the case that without access to the facility, the agency cannot confirm its operational status.”

Safety concern: Grossi went on to say that the agency does not have sufficient information to make an assessment about the Democratic People’s Republic of Korea site, but that nuclear safety remains the paramount issue when starting a new reactor. Agency inspectors have had no access to North Korea since they were expelled in 2009.

The International Atomic Energy Agency completed an advisory service mission to Cambodia on December 11–22 that focused on assessing the country's security regime for nuclear and other radioactive material out of regulatory control (MORC).

The Department of Energy’s National Nuclear Security Administration has published a notice of a final sitewide environmental impact statement for continued operation of Lawrence Livermore National Laboratory (LLNL SWEIS).

The notice was published in the Federal Register on November 3.

The National Nuclear Security Administration’s Office of Radiological Security (ORS), part of the Department of Energy, announced this week that it partnered with Jordan's Energy and Minerals Regulatory Commission (EMRC) to replace all of Jordan’s high-activity cesium-137 irradiators with X-ray technology.

Rafael Mariano Grossi, director general of the International Atomic Energy Agency, officially opened the IAEA Nuclear Security Training and Demonstration Centre during an October 3 ceremony at the agency’s Seibersdorf laboratories in Austria. Representatives of 45 countries and territories were in attendance.

The Department of Energy’s National Nuclear Security Administration recently marked the completion of a new long-term radioactive waste storage facility in Kazakhstan.

The facility, at Kazakhstan’s Institute of Nuclear Physics (INP), has been operational since 2022 and has an expected lifespan of 50 years. According to the NNSA, the facility conforms with all Kazakhstan and International Atomic Energy Agency guidelines and replaces a much older facility located at an INP property in Turaz.

The Department of Commerce’s Bureau of Industry and Security (BIS) has expanded the scope of its nuclear-related export controls on China and Macao (a special administrative region in southeastern China) by establishing additional nuclear nonproliferation controls and license requirements for items that could “contribute to nuclear activities of concern.” The BIS stated that the action, effective August 11, was taken in response to China’s military modernization and nuclear force expansion.

The Department of Energy’s Hanford Site has introduced its newest team members, Dee and Freda, two highly skilled explosive-detecting K-9 officers. The police dogs will work with Richland Operations Office contractor Hanford Mission Integration Solutions to help ensure the safety and security of the legacy nuclear reservation near Richland, Wash.

During a walkdown at Ukraine’s Zaporizhzhia nuclear power plant on July 23, a team of International Atomic Energy Agency experts reported seeing “some” directional antipersonnel mines in a buffer zone between the Russian-occupied site’s internal and external perimeter barriers, the agency announced yesterday.
