Nuclear Issue

    An investigation of supposed Iranian nuclear documents presented in a dramatically staged Netanyahu press conference indicates they were an Israeli fabrication designed to trigger US military conflict with Iran.

    In light of a recent U.S. State Department arms control compliance report highlighting Iran’s growing “uranium enrichment activities and stockpile of enriched uranium,” this report presents recent Iranian breakout estimates and compares them to pivotal historical ones, where breakout is defined as the time Iran would need to produce 25 kilograms of weapon-grade uranium (WGU), enough for a nuclear weapon. As of late February 2020, the breakout estimate is 3.8 months, with a range of 3.1 to 4.6 months. This estimate is based on an Institute breakout calculator, utilizing modified ideal cascade calculations, adjusted with results from an earlier multi-year program of complex computer simulations of Iranian breakout, conducted in collaboration with centrifuge experts at the University of Virginia, and supplemented by operational data on Iranian centrifuges. The breakout estimates result from Iran’s installed enrichment capacity and its stock of low enriched uranium (LEU), as reported by the International Atomic Energy Agency (IAEA) in its quarterly reports on Iran. A significant development is that Iran is at the threshold of having enough LEU to move from a four-step enrichment process to a three-step one, allowing a significant reduction of breakout times, a phenomenon referred to in the media as a “key threshold” or “enough LEU for a nuclear weapon.” A potential covert enrichment plant utilizing 3000 IR-2m centrifuges is also assessed, giving a breakout of 3.1 months. The Annex to this report contains a summary of Iran’s stock of low enriched uranium, based on the IAEA’s most recent quarterly report on Iran, summarizing the situation as of late February 2020 and identifying which of the LEU stocks are used in the breakout calculations.

    On April 8, 2020, one day before Iran’s Nuclear Technology Day, a spokesperson for the Iranian Atomic Energy Organization (IAEO) announced that Iran could produce 60 “advanced” centrifuges a day, with the goal to reach an enrichment capacity of 250,000 separative work units (swu) per year, ultimately one million swu per year.1 It is unlikely, for several reasons, that Iran will reach this capacity with its existing advanced centrifuges for many years, if ever. Currently, its enrichment capacity is about 7500 swu per year (see Annex). This capacity represents a growth of about 20 percent since November 2019 with almost three quarters of that capacity invested in first generation IR-1 centrifuges, the rest in a mélange of advanced centrifuges. To reach 250,000 swu per year, Iran would need to increase its current enrichment capacity 30-fold, entailing the installation and operation of tens of thousands of advanced centrifuges. This goal seems out of Iran’s reach, faced with advanced centrifuges that rarely work as planned and often fail, with a chaotic program that appears to be developing far too many centrifuges, all at best mediocre and poorly performing, and with little chance of ever competing economically with Russian and European centrifuges that supply most of the enrichment needs of nuclear power reactors in the world, including Iran’s own Bushehr reactor.

    This document is an unclassified Executive Summary of the Report that is transmitted pursuant to Section 403 of the Arms Control and Disarmament Act, as amended (22 U.S.C. § 2593a), which requires a report by the President on Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments.  This unclassified Executive Summary is intended to address the requirement in that statute that a report be submitted to Congress not later than April 15 annually.  The full-length unclassified version of the Report will be provided at the earliest possible opportunity consistent with safe personnel and reduced staffing practices necessitated by the COVID-19 pandemic, along with the SECRET and the TOP SECRET/SCI level annexes.

    The International Atomic Energy Agency (IAEA) is reportedly planning to rebuke Iran for its lack of cooperation with the Agency and for refusing to provide access to sites related to its nuclear program. Israeli Prime Minister Benjamin Netanyahu referred to the sites in question in his speech to the United Nations General Assembly in 2018, calling them “Iran’s Secret Atomic Warehouse.”  Netanyahu claimed that Israel had obtained information about these sites — including a trove of documents that purportedly contain information on nuclear weapons design — through secret operations.

    A March 3 report from the International Atomic Energy Agency (IAEA) that Iran is withholding access to two sites connected to its nuclear program and failing to cooperate fully to resolve questions relating to nuclear material has created a potentially problematic situation for states committed to preserving the 2015 nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA).

    Richard Nephew, who served as the lead sanctions expert for the U.S. team negotiating with Iran, is of the opinion that “It is the IAEA's responsibility to investigate information that it receives.”

    “The Agency sought access to two of the locations. Iran has not provided access to these locations and has not engaged in substantive discussions to clarify the Agency’s questions. This is adversely affecting the Agency’s ability to clarify and resolve these questions and to provide credible assurance of the absence of undeclared nuclear material and activities in Iran. I call on Iran to cooperate immediately and fully with the Agency, including by providing prompt access to the locations specified by the Agency.”[…] “The Agency continues to verify the non-diversion of nuclear material declared by Iran under its Safeguards Agreement. Evaluations regarding the absence of undeclared nuclear material and activities in Iran continue,” Mr Grossi added.

    This report of the Director General is on the implementation of the NPT Safeguards Agreement1 and the Additional Protocol2 in the Islamic Republic of Iran (Iran). It describes the Agency’s efforts and interactions with Iran to clarify information relating to the correctness and completeness of Iran’s declarations under its Safeguards Agreement and Additional Protocol.
