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.
It is difficult to assess from photos whether the Sentinel missile is longer or wider overall than the Minuteman, but the Sentinel clearly has a thicker second stage, which could potentially contribute to the missile’s extended range.
This is not the first time Google has agreed to censor imagery at the behest of governments, but be warned: obfuscation at this broad level poses a direct threat to the public’s ability to monitor and scrutinize government operations.
As humans expand our geographic reach, encroach on untouched natural territories, and interact more with animal populations, we will encounter novel zoonotic diseases that threaten the human body. The sooner we act to address these risks, the better.
“One thing became increasingly clear: AI doesn’t simply introduce a new category of risk. It changes the speed, scale, complexity, and interaction of risks that already exist.”
