A senior adviser to Iran’s Supreme Leader, Ali Akbar Velayati, proposed new measures to “revive” Iran’s nuclear capabilities following the U.S. withdrawal from the nuclear accord. Velayati suggested that Iran focus on uranium hexafluoride (UF6)-related facilities, and echoed the Supreme Leader’s call for Iran to bolster its uranium enrichment capacity to 190,000 SWUs. In addition, he proposed additional research and development on the IR-6 and IR-8 centrifuges, the production of carbon fiber needed to make these new generation centrifuges, stable isotope production, and accelerated work on nuclear propulsion systems.
