Iran's Parliament approved a bill requiring the Atomic Energy Organization of Iran (AEOI) to produce at least 120 kilograms of 20 percent enriched uranium annually at the Fordow nuclear facility. Production must begin within two months and the material must be stored in Iran. The bill also requires the AEOI to increase monthly production of enriched uranium to 500 kilograms; install and begin enrichment in at least 1,000 IR-2m centrifuges at the underground facility at Natanz; move enrichment research and development operations on the IR-6 centrifuges to Fordow; use 1000 IR-6 machines for enrichment at Fordow by March 2021; and return the Arak heavy water reactor to its "pre-JCPOA condition" within four months. Within two months, the AEOI must suspend access to nuclear sites beyond what is required by the International Atomic Energy Agency's (IAEA) Additional Protocol and stop voluntary implementation of the Protocol if Europe fails to restore banking relations with Iran that allow for the sale of oil.
