Today marks 90 days since the United Nations Security Council endorsed the landmark nuclear accord agreed between Iran and six world powers (the U.S., Britain, France, Germany China and Russia.)
The Joint Comprehensive Plan of Action (JCPOA) will unfold in a series of steps that include nuclear cutbacks made by Iran and sanctions relief offered by the other countries. The phase that begins now is of special interest to nuclear non-proliferation experts.
Those wanting to keep Iran, or any nation, from newly acquiring nuclear weapons will be very happy to see the steps Tehran has pledged to begin taking now. They will greatly shrink the capacity and scope of the Iranian nuclear program, in ways that sharply limit its ability to produce the kind of nuclear fuel that could be used in a weapon.
Less Enrichment, Tinier Fuel Stockpile, No Plutonium
Under the JCPOA, Iran will now:
- Reduce its stockpile of low enriched uranium by some 98 percent, either shipping it out of the country or diluting it down to its natural state. (Low enriched uranium, usually less than 5 percent purity, is suitable for generating electricity. At about 20 percent, enriched uranium has uses in medical research; Iran has agreed not to enrich uranium to that level for 15 years. Weapons grade uranium is enriched to around 90 percent.)
- Remove thousands of centrifuges from the enrichment facilities at Natanz and Fordow, leaving a total of 5,060 working centrifuges (the underground facility at Fordow, a major concern to those worried about a possible secret Iranian nuclear weapons program, will have no centrifuges enriching uranium.)
- Take out the core at the Arak heavy water reactor and fill it with concrete. The reactor will eventually be converted so that it produces only a minimal amount of the other main nuclear fuel, plutonium.
Explaining The Past, And Inviting Tougher Inspections
This phase of the agreement should also see Iran answering long-held questions by the International Atomic Energy Agency (IAEA) about Iran's past nuclear activities. Last week, the IAEA announced that Iran had completed responding to IAEA queries on 12 such activities that could have possible military dimensions. The agency is due to report its finding on these issues on December 15th.
The IAEA is also ramping up for a far more intrusive and high-tech inspection regime of Iran's entire nuclear fuel chain, from the uranium mine to processing mills to conversion and enrichment facilities. The goal is to permit IAEA inspectors to track every gram of nuclear material from start to finish, to ensure that nothing is diverted to a covert weapons program.
Critics say the inspection regime, while stronger than the previous one, still has flaws and compromises that could allow Iran to cheat and move closer to weapons capability under the agreement. They point to a recent inspection of the controversial Parchin military site, in which Iranian technicians took environmental samples instead of IAEA inspectors. The agency says the procedure, while not routine, conforms to its standards.
What About Sanctions Relief?
When Iran marks the nuclear deal with events on Monday, it will be focusing on the lifting of international economic sanctions that have depressed its economy, along with falling oil prices. But sanctions relief won't come until the IAEA certifies that Iran has met all its nuclear obligations. Once that happens, there will be another milestone, known as "implementation day."
Iranian officials say they can complete the nuclear cutbacks by the end of the year, but western nuclear experts think it will probably be weeks, even months into 2016 before that happens.
Critics of this agreement worry that Iran will use some of the money it receives from sanctions relief to further its regional ambitions in the already destabilized Mideast. The latest criticism comes after Iran tested a medium-range ballistic missile.
A senior administration official says the missile test is a concern and a violation of U.N. Security Council resolutions, but it's not a violation of the nuclear accord. The official says the U.S. has "other tools" to address Iran's regional moves.
