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.

Transformers: Cooler Side of the Grid
Failures in transformers cause widespread disruptions across electrical networks, severely affecting grid stability. The financial impact of such failures often goes beyond just the cost of replacing the transformer. Simulations on NSF-funded Stampede2 provide models for a resilient and sustainable electric grid.

Tornadoes Are Deadly. These New Building Codes Will Save Lives.
Because of its unique geography, the United States has more tornadoes, and more intense tornadoes, than any other country. Tornadoes are deadly, but until recently there were no building codes designed to protect communities from tornadoes. Tornado winds push and pull on buildings in unique ways that require special safety designs. NIST research led to the first building code provision for tornado resilience.

Disaster Recovery: What Community-Driven Relocation Could Look Like
Over the past forty years, the Gulf Region has experienced devastating hurricanes and flooding, costing 232 billion dollars. The gut reaction after any disaster is to rebuild and protect-in-place, but sometimes communities have to consider relocation — but the conversations around rebuilding versus relocation continue to be challenging for policymakers and the communities impacted by disasters.

Researchers Spot Potential Hazard with Private Well Water Treatment
While arsenic is a naturally occurring element, it is a known human carcinogen and dangerous to human health. Systems designed to treat arsenic in private well water may be malfunctioning and endangering the health of people who count on them to keep their water safe.

Scientists Call for ‘Major Initiative’ to Study Whether Geoengineering Should Be Used on Glaciers
A group of scientists has released a landmark report on glacial geoengineering—an emerging field studying whether technology could halt the melting of glaciers and ice sheets as climate change progresses. Their report finds many questions remain around technology to address glacier melting and sea-level rise.

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.

Nuclear Electricity Supply Would Be Less Vulnerable to Attack Than Renewables
Renewable energy generation is not as robust in the face of enemy attack as it looks. Nuclear power, even though it would probably be concentrated in a few large generating stations, should in fact be a little more dependable in wartime.

To Guard Against Cyberattacks in Space, Researchers Ask ‘What If?’
If space systems such as GPS were hacked and knocked offline, much of the world would instantly be returned to the communications and navigation technologies of the 1950s. Yet space cybersecurity is largely invisible to the public at a time of heightened geopolitical tensions.

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.

Water Wars: A Historic Agreement Between Mexico and US Is Ramping Up Border Tension
As climate change drives rising temperatures and changes in rainfall, Mexico and the US are in the middle of a conflict over water, putting an additional strain on their relationship. Partly due to constant droughts, Mexico has struggled to maintain its water deliveries for much of the last 25 years, deliveries to which it is obligated by a 1944 water-sharing agreement between the two countries.
Trump Is Fast-Tracking New Coal Mines — Even When They Don’t Make Economic Sense
In Appalachian Tennessee, mines shut down and couldn’t pay their debts. Now a new one is opening under the guise of an “energy emergency.”
Smaller Nuclear Reactors Spark Renewed Interest in a Once-Shunned Energy Source
In the past two years, half the states have taken action to promote nuclear power, from creating nuclear task forces to integrating nuclear into long-term energy plans.
