Kazakh company Kazatomprom has delayed a natural uranium concentrate delivery to Iran pending approval from the P5+1 countries party to the nuclear agreement. Kazakhstan first signed a contract with Iran in April 2016 to supply the uranium concentrate and had planned to begin delivery this year. The firm has extended its contract with Iran through 2020 and has rescheduled the delivery to take place during the 2018-2020 period, if approved by the P5+1.
