Iran's IR-1 centrifuge

The IR-1 centrifuge is a machine used by Iran to enrich uranium by spinning uranium hexafluoride gas at high speeds, increasing the concentration of the fissile isotope U-235. It’s a key component of Iran’s nuclear program, effectively separating and concentrating uranium isotopes to produce fuel for nuclear reactors or, potentially, weapons. The IR-1 is based on technology originally designed in the 1970s and has been subject to international scrutiny and sanctions. Its efficiency, reliability, and design have evolved over time, but it remains fundamental to Iran’s nuclear activities.
