The International Atomic Energy Agency (IAEA) reported on April 21 that Iran had installed six cascades of "up to" 1,044 IR-2m centrifuges and two cascades of "up to" 348 IR-4 centrifuges at the underground portion of the Natanz nuclear site. The IAEA did not specify how many of the newly installed centrifuges Iran was using to enrich uranium. Iran also informed the IAEA that it plans to install four additional cascades of IR-4 centrifuges in the underground facility, where an explosion and power outage earlier in the month damaged an unknown number of centrifuges. The Joint Comprehensive Plan of Action (JCPOA), the 2015 international agreement restricting Iran's nuclear program, limits the country to the use of less efficient IR-1 centrifuges at the underground portion of Natanz.
