Simultaneous Detection of Uranium Isotopes, Fluorine Advances Nuclear Nonproliferation Monitoring
Fluorine is essential for converting uranium into a form suitable for enrichment, so spotting both elements together may help inspectors determine the intended use of a nuclear material.

We Need a New Discussion About Iran’s Nuclear Weapons Work
U.S. intelligence is shielding the Biden-Harris administration from having to take serious action on Iran’s nuclear program. While hinting at nuclear weapon activities taking place, the U.S. intelligence community is focusing on public Iranian statements and old news on Iran’s capabilities to produce weapon-grade uranium — but it avoids any type of public discussion on what nuclear weaponization activities Iran may be undertaking, and how soon it can build a nuclear weapon. Likely, because some uncomfortable truths would come out: Iran can do it way too quickly, and initial activities to build the bomb could be difficult to detect.

Uranium Science Researchers Investigate Feasibility of Intentional Nuclear Forensics
Despite strong regulations and robust international safeguards, authorities routinely interdict nuclear materials outside of regulatory control. Researchers are exploring a new method that would give authorities the ability to analyze intercepted nuclear material and determine where it originated.

How Do You Convince Someone to Live Next to a Nuclear Waste Site?
The world’s first permanent depository for nuclear fuel waste opens later this year on Olkiluoto, a sparsely populated and lushly forested island in the Baltic Sea three hours north of Helsinki. Engineers know how to build a site that can safeguard nuclear waste for 100,000 years. The challenge is convincing people to live next to it.

Nonproliferation Researcher Is Retracing Reactor Steps
Nuclear materials can produce vast amounts of energy. This unique attribute can be harnessed through reactors to provide a reliable, low-carbon electricity source. It can also be used to make weapons.

Hardy Transistor Material Could Be Game-Changer for Nuclear Reactor Safety Monitoring
The safety and efficiency of a large, complex nuclear reactor can be enhanced by hardware as simple as a tiny sensor that monitors a cooling system. That’s why researchers are working to make those basic sensors more accurate by pairing them with electronics that can withstand the intense radiation inside a reactor.

‘Risks of Nuclear Terrorism Are High and Growing.’ New Tools, Alliances, Renewed Focus Needed, experts recommend
For roughly 80 years, the United States has managed the threat of nuclear terrorism through nonproliferation treaties, agency programs, intelligence activities, international monitoring support and more, withstanding the Cold War, the fall of the Soviet Union, and 9/11. A National Academies committee wants to ensure the U.S. remains prepared.

Iran Can Now Produce Enough Fissile Material for 5 Nuclear Bombs within 30 Days of Decision to Do So
Iran notified the IAEA recently that over the next 3-4 weeks it would install eight cascades each containing 174 IR-6 centrifuges, about 1,400 in total, at the underground Fordow Enrichment Plant. The installation of eight more IR-6 cascades represents a dramatic increase in Fordow’s total enrichment capacity, meaning that by the end of the first month from a decision to “go nuclear,” Iran could produce a total of 145 kg of WGU, enough for five nuclear weapons.

Evaluating U.S. Readiness to Prevent, Counter, and Respond to WMD
Two new reports review the adequacy of U.S. strategies to prevent, counter, and respond to the threat of nuclear and chemical terrorism and highlight the strengths and limitations of U.S. efforts to prevent and counter threats from weapons of mass destruction (WMD), particularly in a changing terrorism threat landscape.
