Earlier this month, nearly 250 personnel at the Department of Energy’s Savannah River Site in South Carolina took part in an annual exercise to test preparedness for a radiological release and contamination emergency.

International Atomic Energy Agency director general Rafael Mariano Grossi was in Switzerland last week to talk with insurance executives at the Nuclear Pools’ Forum about the potential of nuclear power.

The board of governors for the International Atomic Energy Agency censured Iran this week for its failure to cooperate with access requests and materials needed to confirm that the Middle Eastern nation is adhering to nuclear safeguard obligations.

During the 2024 International Conference on Nuclear Security (ICONS) in May, representatives from the U.S. Department of Energy and the National Nuclear Security Administration discussed U.S. nuclear security priorities, noted their achievements and those of U.S. partners, and explained how to tackle the security challenges of today and tomorrow.

Greg Bowman and George Smith work for the Nuclear Regulatory Commission in implementing programs that deal with risk, whether to nuclear power plants or from nuclear materials, such as radiological sabotage and theft or diversion of materials. Bowman is the director of the NRC’s Division of Physical and Cybersecurity Policy in the Office of Nuclear Security and Incident Response. Smith is the senior project manager for security in the Source Management & Protection Branch of the Division of Materials Safety, Security, State, and Tribal Programs in the Office of Nuclear Material Safety and Safeguards.

The three initiatives Bowman and Smith discussed with Nuclear News editor-in-chief Rick Michal are the Insider Threat Program, the Cybersecurity Program, and the Domestic Safeguards Program.

The term “dirty bomb” surfaces occasionally, usually in the context of nuclear waste, which, while understandable, is incorrect.

Dirty bombs, or radiation dispersal devices (RDDs), use conventional methods like car bombs to disperse radioactive materials in populated economic districts, such as lower Manhattan. The point is to cause great economic and social disruption disproportionate to the actual radiological effects—and well beyond the physical destruction from the conventional bomb components.

Society’s irrational fear of radiation makes the dirty bomb an ultimate weapon of terror. But it is a psychological weapon, not a nuclear one. The public should not be any more afraid of a dirty bomb than they are of an ordinary car bomb.

Ukraine’s Zaporizhzhia nuclear power plant temporarily lost the connection to its sole remaining 750 kilovolt (kV) off-site power line last week due to a reported short circuit, leaving it reliant on a single backup line for more than three hours.

Ensuring that nuclear technology is used exclusively for peaceful purposes remains a critical challenge for our society today. The global community faces several grave nuclear security threats: nations that attempt to create (such as Iran) or augment (such as Russia, China, and North Korea) their nuclear arsenals, acts of aggression that target civilian nuclear reactors (as seen with Russia in Ukraine), and the looming menace of nuclear weapons deployment (emanating from Russia). Furthermore, addressing climate change necessitates an expansion of nuclear energy for electricity generation, which brings with it the need for safeguarding and regulating the deployment of advanced reactors.

During the International Atomic Energy Agency’s International Conference on Nuclear Security this week, leaders from the U.S. Department of Energy’s National Nuclear Security Administration and the European Commission made a joint statement on enhancing radioactive source security.

Last year, 168 incidents of illegal or unauthorized activities involving nuclear and other radioactive materials were reported to the International Atomic Energy Agency’s Incident and Trafficking Database (ITDB). According to the agency, this number is in line with historical averages. These incidents were reported by 31 IAEA member states; as of 2023, a total of 145 member states have participated in the ITDB.

Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

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.
