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.

Memo: The Reported Destruction of Secret Workshop in 2020
On March 24, 2024, Iran International reported that an “industrial production workshop […] belonging to the Atomic Energy Organization of Iran (AEOI) was deliberately set on fire” in the summer of 2020. 1 The incident was not reported publicly at the time, and Iran International cites judicial and intelligence documents provided by a hacking group as their source. Iran alleged that the Israeli intelligence service, Mossad, hired a group of nine Iranians to destroy the facility.

A Non-Proliferation Solution: Using Antineutrinos to Surveil Nuclear Reactors
Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, scientists report. Thanks to a newly developed method, it is now possible to estimate a reactor’s operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

Nuclear Engineer Uses Machine Learning on Weapons Testing Images to Understand Fallout
After WWII, the U.S. wanted to better understand what happened after a nuclear weapon was detonated. Researchers conducted tests in the southwestern U.S. and the Pacific Ocean and recorded those experiments on film. Scientists used the original reel-to-reel films to manually measure data from the blasts. Today, nuclear forensic scientists combine modern computational techniques with the historical records of nuclear tests to obtain precious insights into the physics of these type of events, which are otherwise hard to study experimentally.
