(CNN)Parameters for a Joint Comprehensive Plan of Action regarding the Islamic Republic of Iran's Nuclear Program

Below are the key parameters of a Joint Comprehensive Plan of Action (JCPOA) regarding the Islamic Republic of Iran's nuclear program that were decided in Lausanne, Switzerland. These elements form the foundation upon which the final text of the JCPOA will be written between now and June 30, and reflect the significant progress that has been made in discussions between the P5+1, the European Union, and Iran. Important implementation details are still subject to negotiation, and nothing is agreed until everything is agreed. We will work to conclude the JCPOA based on these parameters over the coming months.
    Enrichment
      • Iran has agreed to reduce by approximately two-thirds its installed centrifuges. Iran will go from having about 19,000 installed today to 6,104 installed under the deal, with only 5,060 of these enriching uranium for 10 years. All 6,104 centrifuges will be IR-1s, Iran's first-generation centrifuge.
      • Iran has agreed to not enrich uranium over 3.67 percent for at least 15 years.
      • Iran has agreed to reduce its current stockpile of about 10,000 kg of low-enriched uranium (LEU) to 300 kg of 3.67 percent LEU for 15 years.
      • All excess centrifuges and enrichment infrastructure will be placed in IAEA monitored storage and will be used only as replacements for operating centrifuges and equipment.
      • Iran has agreed to not build any new facilities for the purpose of enriching uranium for 15 years.
      • Iran's breakout timeline -- the time that it would take for Iran to acquire enough fissile material for one weapon -- is currently assessed to be 2 to 3 months. That timeline will be extended to at least one year, for a duration of at least ten years, under this framework.
      Iran will convert its facility at Fordow so that it is no longer used to enrich uranium
      • Iran has agreed to not enrich uranium at its Fordow facility for at least 15 years.
