Happy Iranian Nuclear Day! And everything you have ever wanted to know about centrifuges.
Yes, today, 9 April, is the official Iranian holiday to celebrate all the progress that the Iranians have made toward nuclear self-sufficiency. The Iranian nuclear program is getting lots of news, especially their effort to enrich uranium using centrifuges and today’s inauguration of their new fuel fabrication facility. The fundamental problem with centrifuges is that they can be used to produce uranium for a nuclear reactor but the very same machines can also be used to produce uranium for a nuclear bomb. The Iranians protest that they have every right to nuclear power while the rest of the world worries that the entire nuclear power enterprise is a thin cover for a bomb program.
If you have ever wondered how centrifuges work, how they are built, or their link between bombs and power plants, the Federation of American Scientists has answered your question. My colleague, Ivanka Barzashka, and I have just published an entirely new section of the FAS website explaining centrifuge technology and the associated proliferation concerns. It even includes a nice animated video that demonstrates how centrifuges work. I believe that this is the single best resource on centrifuge technology on the web.
Soon, Ms Barzashaka, will post additional sections that look specifically at the Iranian centrifuge program, analyzing what the capabilities of their machines are and how fast they can enrich uranium.
The bootcamp brought more than two dozen next-generation open-source practitioners from across the United States to Washington DC, where they participated in interactive modules, group discussions, and hands-on sleuthing.
Is sole authority solvable, or is it truly the best system possible for nuclear launch authority? If the latter, should we accept that reality?
On September 3, 2025, China showcased its military power in a parade commemorating the 80th Anniversary of the end of World War II. The parade featured a large number of new military weapons and equipment, including new and modified nuclear systems that had not been previously publicly displayed. This parade was also the first time […]
With 2000 nuclear weapons on alert, far more powerful than the first bomb tested in the Jornada Del Muerto during the Trinity Test 80 years ago, our world has been fundamentally altered.
