UPDATE: Iran’s senior nuclear negotiator Abbas Araqchi told reports on Sunday in Lausanne that Iran will not send its current stockpile of enriched uranium abroad for conversion into power reactor fuel. The transfer of enrich uranium abroad, most probably Russia, has been among key demands of all members of P5+1. If Iran sticks to its position, then to ensure that the breakout capability is not shorter than one year, Iran would need to agree to much lower number of centrifuges that would be allowed to operate. Tough choices.
Western reporters at Iran talks in Lausanne are reporting as of Sunday afternoon local time that the two sides are seriously exploring compromises to break an impasse in nuclear talks. A plenary session of foreign ministers of Iran and six major powers will convene later today to approve possible compromises that would form the basis of a political framework agreement, with technical details worked out before 30 June deadline for a joint comprehensive accord.
FWIW, there are reports of compromises in the making this afternoon, which include Iran’s acceptance of having fewer than 6,000 centrifuges and shipping nearly all its current stockpile of enriched uranium to Russia for conversion into nuclear reactor fuel. The P5+1 would in return allow continued operation at Fordo enrichment facility, albeit limited to R&D work for medical purposes under close monitoring of IAEA. The duration of the agreement, the so-called sunset clause, is said to be 11-15 years, containing different duration for different elements of a deal, with additional protocol and modified code 3.1 to NPT obligations lasting forever.
UPDATE: AFP quoted Iran's senior negotiator Abbas Araqchi as saying that Iran would never accept the demand by the P5+1 to send its stockpile of enriched uranium abroad. With the stockpile kept intact in Iran, the P5+1 might demand much lower number of operating centrifuges allowed, which Iran might not be willing to accept. In the last hours of negotiations, they are taking one step forward and one backward, the German foreign minister observed.
UPDATE: P5+1 and EU tonight held meeting among themselves for the first time since November extension of interim agreement, JPOA.
UPDATE: The plenary session of foreign ministers of Iran and six major powers will be held on Monday morning at 9 AM local time. The meeting was originally scheduled to be held tonight.
