At a time of geopolitical upheaval, the @IAEAorg.bsky.social nuclear security recommendations are central to preventing nuclear terrorism and sustaining global confidence in the peaceful use of nuclear technologies. Those recommendations are now undergoing their first update. 🧵 ⤵️

New START Has Expired. Congress’s Oversight Tools Shouldn’t. Congress’s oversight of U.S. nuclear policy is at a critical juncture. When the U.S. Senate approved New START in 2010, it mandated several annual reports and certifications to ensure strong…

"As the United States enters a new era of nuclear competition, Congress’s actions can still reverberate positively and help keep U.S. nuclear policy on a stable path," writes NTI's Paul Warnke. ⤵️

The future of nuclear energy depends on getting today’s technology choices right.

Today, the Nuclear Scaling Initiative published the Reactor Selection Tool—a platform designed to guide reactor selection based on 8 key criteria, including safety, security, cost, supply chain & deployment timeline.

"Reprocessing is commercially untenable because it’s expensive, dangerous and it doesn’t work as advertised," writes NTI's Ross Matzkin-Bridger in a letter to the editor for the @washingtonpost.com.

How the U.S. Maintains Its Nuclear Arsenal—Without Explosive Testing The U.S. ended explosive nuclear testing in the 1990s, but that does not mean we are unprepared. In its place, the U.S. uses a science-based program that checks the health of the stockpile…

Testing nuclear weapons is unnecessary for U.S. national security, unwise because it will invite our adversaries to do the same, and unwelcome in communities close to the test site.

“No one knows how this will end, or when, but when it does, I think our priority has to be to get the IAEA, the international inspectors, back into Iran,” says NTI’s Co-Chair, Ernest Moniz says on the recent strikes on Iran.

Whether or not there is regime change in Iran, the international community should insist that Iran allow the return of international inspectors immediately after the cessation of military operations to begin the arduous process of accounting for nuclear materials.

The House of Dynamite We Forgot: And What We Can Learn From Nuclear History Revisiting Nuclear Alerts and System Failures of the 1980s

In 1983, Soviet officer Stanislav Petrov called a warning of an incoming missile from the United States a false alarm. His judgement was accurate and might have saved the world.

In an era of rising nuclear risk, the lessons we can learn from nuclear history are many.

Statement by NTI on the U.S.-Israel Strikes on Iran The ongoing major combat operations introduce serious nuclear security and proliferation risks.

Today, the US began a military campaign targeting Iran’s political leadership, nuclear program, and conventional military forces, with the goal of collapsing its government.

Yesterday, Rev. Jesse Jackson passed away at the age of 84.

He was an inspiring civil rights leader and a staunch advocate for nuclear risk reduction. Nuclear disarmament was a key component of his 1984 presidential run, and he stated that, “we will choose the human race over the nuclear race.”

In an interview with Mary Louise Kelly at #MSC2026, our CEO Christine Wormuth said, "I hope we're not going to be going back to the days of drills underneath desks, but I do think we're in a perilous new era where we could see an arms race."

How Funders Can Make Life Science Research Safer and Faster Life science research moves quickly. But not all research carries the same level or type of risk. For funders, the challenge is to identify risks early—without slowing critical research. And…

When funders support groundbreaking life science research, they are investing in discoveries that could save lives.

But what if that same research, in the wrong hands or under unsafe conditions, could cause harm? www.nti.org/risky-busine...
