Head of the Atomic Energy Organization of Iran (AEOI) Ali-Akbar Salehi said on Monday that agreement on supply of 40 tons heavy water to Russia has not been finalized yet, IRNA reported.
Salehi was speaking to reporters on the sidelines of a ceremony for signing a cooperation agreement between the AEOI and the Ministry of Petroleum on different scientific and research areas, particularly those related to production of ultra centrifuges.
Russia demanded 40 tons heavy water from Iran, Salehi said.
However, he noted that Iran and Russia are still in talks and the negotiations are not finalized yet.
He said, in the meantime, that Iran and Russia are currently involved in cooperation to produce stable isotopes in Fordo site, central Iran.
Asked about selling Iranian heavy water to the US, Salehi said that the US is required to pay the bill in advance prior to shipment of the heavy water.
'We must make sure about the payment. Otherwise, we will not deliver heavy water to the US.'
Salehi said that after the seizure of two billion dollars of Iranian assets by the US government, he asked his colleagues at the AEOI to refrain from sending the cargo to the US.
