On November 5, 2019, Iranian president Hassan Rouhani announced that Iran will begin injecting centrifuges with uranium hexafluoride (UF6) gas at the Fordo nuclear plant. Rouhani said that this enrichment activity will be done under the supervision of the IAEA. Rouhani clarified that this step is reversible and if the signatories to the JCPOA will return to their commitments, so will Iran. The speech was delivered at a factory dedication in Iran and aired on IRINN TV.
Following are excerpts:
Hassan Rouhani: Starting tomorrow, we will take the fourth step [in reducing our nuclear commitments]. We are informing the 4+1 states and countries friendly to us in advance that our new activity will also be supervised by the IAEA. The IAEA will continue to supervise even the activity we start tomorrow. This is the first point. The second point is that like the first three measures we have taken, this fourth step is reversible. Whenever they return to their full commitments, we will follow suit.
The measure we begin tomorrow is in Fordo. As you know, in keeping with the JCPOA, we have 1,000 centrifuges there... 1,044 I think.
However, in the JCPOA we agreed that the centrifuges would turn, but would not inject [UF6] gas into them. The measure that we will take tomorrow – and today I will deliver a binding instruction to the [Iranian] Atomic Energy Organization – is to begin injecting gas in Fordo tomorrow. This may cause turmoil. They might say: "What, you want to do this in Fordo?" We know all that. We are aware of the sensitivities regarding Fordo and those centrifuges. Yet, when they fulfill their commitments, we will stop the gas injection.
