IAEA Warns on North Korea and Iran
IAEA Director Rafael Grossi issued dire warnings, saying Pyongyang may be reprocessing plutonium and that Iran’s lack of compliance is hurting prospects for salvaging the JCPOA (the 2015 nuclear deal). Pyongyang has continued to pursue its nuclear ambitions since that time and detonated its last nuclear device in 2017, while working with Iran was “becoming increasingly difficult.”

Iran Nuclear Inspection Deal with UN Watchdog Extended by One Month

Syrian Missile Explodes Near Israel’s Dimona Nuclear Reactor
A Syrian missile landed and exploded about forty miles from Israel’s nuclear reactor in Dimona. The IDF described the incident as unintentional: A Russia-made SA-5 was launched by a Syrian air defense unit, aiming at an IDF aircraft attacking Syrian military targets near Damascus. It appears that the Syrian missile had missed its target, and continued its flight trajectory which carried it all the way to the Negev desert, about 300 kilometers south of Damascus. There is unease in Israel over the fact that the missile managed to evade Israel’s robust anti-missile defenses.

U.S. Should Make Monitoring and Detecting Nuclear Threats a Higher National Priority
To address current and evolving nuclear threats, the U.S. needs a higher prioritized and more integrated program for monitoring, detecting, and verifying nuclear test explosions, nuclear weapon stockpiles, and the production of fissile material, says a new report from the National Academies of Sciences.

Iran Says 60 Percent Enrichment “Under Way” at Natanz Site
Iranian officials say the country has begun enriching uranium up to 60 percent purity, higher than it has ever done before, despite ongoing talks between Tehran and world powers to revive the 2015 nuclear deal. Under the 2015 nuclear deal, Iran had committed to keep enrichment to 3.67 percent. Recently it has been enriching up to 20 percent, saying the deal was no longer enforceable. Enriching uranium to 60 percent would be the highest level achieved by Iran’s nuclear program, it is still short of the 90 percent purity needed for military use.

Natanz Attack Sets Back Iran’s Nuclear Operations
The Israeli Sunday sabotage operation against Iran’s nuclear facility at Natanz destroyed a well-protected electrical substation housed 40 to 50 meters underground.Iranian officials said that thedestruction of the power supply led to the damage or destruction of “thousands of centrifuges” by causing them to slow down too rapidly.

Working Toward a More Secure World
Neutron resonance transmission analysis (NRTA), which is used for identifying specific kinds of special nuclear materials. Elements come in different forms, or isotopes, and one way to differentiate among isotopes is to bombard them with neutrons. A reliable method for pinning down the nature of nuclear materials is crucial in nuclear security, where verification of weapons treaties may depend on establishing if a warhead slated for elimination is real or fake. The same kind of technology is useful for determining the enrichment status of nuclear fuel, or for revealing the presence of concealed radioactive material.

Iran Begins Uranium Enrichment with More Advanced Centrifuges
Iran has begun enriching uranium at its underground Natanz plant using a cascade of advanced centrifuges, the latest breach of a 2015 nuclear deal with world powers. The use of the advanced centrifuges is the latest violation of the nuclear accord, which only allows slower first-generation IR-1 centrifuges for enrichment.

Explainable AI: A Must for Nuclear Nonproliferation, National Security
As it is with raw human intelligence, so it is with artificial intelligence (AI). We may not know exactly what’s going on inside that elaborate black box built by humans, but its decisions can be so accurate that it earns our trust, if not our comprehension. But the need for understanding escalates when the stakes are higher. For national security concerns, it’s not good enough to know that a system works; scientists demand to know how and why. That’s the foundation for a field of study known as “explainable AI.”

U.S. Says It's Ready to Meet, but Iran Says Sanctions Should Be Dropped First
Iran says it will “immediately reverse” its actions that contradict a 2015 nuclear agreement once U.S. sanctions are lifted after Washington said it was ready to revive the deal that former U.S. President Donald Trump abandoned in 2018 before reimposing the crippling penalties on Tehran.
