Producing Medical Isotopes While Lowering the Risk of Nuclear Weapons Proliferation
Scientists and engineers at Argonne have been working for decades to help medical isotope production facilities around the world change from the use of highly enriched uranium (HEU) to the use of low-enriched uranium (LEU), which is much more difficult to use in a weapon.

Enhancing Advanced Nuclear Reactor Analysis
Nuclear power is a significant source of steady carbon-neutral electricity, and advanced reactors can add more of it to the U.S. grid, which is vital for the environment and economy. Sandia Lab researchers have developed a standardized screening method to determine the most important radioactive isotopes that could leave an advanced reactor site in the unlikely event of an accident.

Creating a Tsunami Early Warning System Using Artificial Intelligence
Tsunamis are incredibly destructive waves that can destroy coastal infrastructure and cause loss of life. Early warnings for such natural disasters are difficult because the risk of a tsunami is highly dependent on the features of the underwater earthquake that triggers it.

Germany: Seeking Solution for Remaining Nuclear Waste
Nuclear energy in Germany has been history since mid-April. The last three nuclear power plants ended their operations on April 15. Germany’s nuclear power might be gone, but nuclear waste isn’t going anywhere. The search for a location for a final repository remains a challenge.

Poisons Are a Potent Tool for Murder in Fiction – a Toxicologist Explains How Some Dangerous Chemicals Kill
People have used poisons throughout history for a variety of purposes: to hunt animals for food, to treat diseases and to achieve nefarious ends like murder and assassination. But what is a poison? Do all poisons act in the same way? Does the amount of the poison matter in terms of its toxicity?

Using GSI Sensor Technology to Prediction Earthquakes
Can nuclear physics improve the prediction of earthquakes? As part of a new project which aims to provide the foundation for a reliable early warning system for earthquakes in Europe, researchers are building a network of sensors measuring radon levels and other parameters in selected water sources in Europe might be able to detect earthquakes several days in advance.

North Korea’s Nuclear Tests Expose Neighbors to Radiation Risks
Tens of thousands of North Koreans and people in South Korea, Japan, and China could be exposed to radioactive materials spread through groundwater from an underground nuclear test site. North Korea secretly conducted six tests of nuclear weapons at the Punggye-ri site in the mountainous North Hamgyong Province between 2006 and 2017.

Iran Enriching Uranium to Near-Weapon-Grade 84%: IAEA
IAEA inspectors found uranium particles enriched up to nearly 84 percent in Iran’s underground Fordow uranium enrichment site. The 83.7 percent enriched uranium is just below the 90 percent purity needed for nuclear weapons. Experts say that Iran would need no more than 10-14 days to use the material to produce an atomic bomb.

Can You Tell Whether a “Bomb Train” Is Coming to Your Town? It’s Complicated.
This information about trains carrying hazardous materials is out there, but it is not always readily accessible. With the derailment of the Norfolk Southern train receiving international attention, more railroad communities are now asking what is traveling through their backyard, and how to avoid the fate of East Palestine, Ohio.

Ohio Chemical Spill Draws Focus on Railroad Dangers
The U.S. has one of the most extensive rail networks in the world, but diminishing safety standards puts people and the environment at risk. The latest accident has drawn sharp focus onto the safety standards of the highly profitable freight rail industry and its prolific lobbying against regulation.

The Train Derailment in Ohio Was a Disaster Waiting to Happen
The derailment of a freight train filled with volatile chemicals in rural Ohio earlier this month captured the headlines, but researchers and chemical spill experts say it’s a situation that plays out far too often across the country. Trains carry hazardous chemicals everyday. They’re also dangerously unregulated.

Improving the Speed and Safety of Airport Security Screening
For decades, airports around the nation have employed sensitive canine noses to detect concealed explosives. While this four-legged fleet has been effective and efficient, researchers have yet to build a mechanical method that can mimic their abilities. Researchers seek ways to build non-contact screening methods that can detect concealed explosives at airports.

The long view
Sniff Test for Explosives Detection Extends Its Reach
Scientists have developed a way to detect tiny amounts of hard-to-detect explosives more than eight feet away, reducing the need to swipe clothing, luggage or other materials. The nNew method detects dangerous materials with lower vapor pressure.
No Power, No Operator, No Problem: Simulating Nuclear Reactors to Explore Next-Generation Nuclear Safety Systems
To create safe and efficient nuclear reactors, designers and regulators need reliable data consistent with real-world observation. Data generated at the facility validates computational models and guides the design of nuclear reactors.
