"Iran's full transparency is indispensable and overdue," it continues, adding that the agency questions Iran's motives for not declaring certain factors and "pursuing a policy of containment." The resolution does not refer Iran to the UN Security Council, but it does hint at this possibility by noting that some of the outstanding questions are "within the competence of the Security Council. The resolution was approved by a vote of 22 in favor, 1 against (Venezuela), and 12 abstentions. (See also, "Iranian Government Reacts To IAEA Nuclear Resolution.")
17 September 2005 -- President Mahmud Ahmadinejad announces the Iranian position on the nuclear issue at the UN General Assembly. "Peaceful use of nuclear energy without possession of nuclear fuel cycle is an empty proposition," he said. He expressed concern about the creation of a nuclear "apartheid," and he calls for a nuclear-weapons-free Middle East. "In accordance with our religious principles, pursuit of nuclear weapons is prohibited," Ahmadinejad said. As a confidence-building measure, Ahmadinejad said, Iran is willing to partner with public and private groups in its uranium-enrichment program. He added that Iran will continue to cooperate with the International Atomic Energy Agency. However, he dismissed promises that other countries will be the source of fuel for the Iranian nuclear program.
2 September 2005 -- Members of the IAEA Board of Governors receive a report on Iran's nuclear activities. It notes that Tehran has been less than forthcoming about some of its activities and has been reluctant to provide access to some sites. "In view of the fact that the agency is not in a position to clarify some important outstanding issues after two and a half years of intensive inspection and investigation, Iran's full transparency is indispensable and overdue," the report states. "Given Iran's past concealment efforts over many years...transparency measures should extend beyond the formal requirements...and should include access to individuals, documentation on procurement, and dual-use equipment."
August 2005 -- Iran rejects the EU proposal, which includes commercial and political cooperation in exchange for Iran's forsaking efforts to develop nuclear fuel. (See also, "IAEA Draft Resolution Expresses 'Serious Concern' Over Iran's Nuclear Activities.") The European proposal included an offer to help build a light-water reactor and then provide fuel for it. (Fuel for a light-water reactor is cannot be used for weapons.)
July 2005 -- President Khatami says on 19 July that Iran will not forsake the right to produce nuclear fuel and the enrichment suspension will not be permanent. He says on 27 July that activities at the Isfahan UCF could resume in days, depending on the concessions proposed at an Iran-EU meeting. "The system has already made its decision to resume Isfahan's activities," he said.
May 2005 -- Iranian officials repeat that activities at Isfahan UCF will resume "soon," but then Tehran agrees to wait for two months after Iranian and EU officials meet in Geneva.
April 2005 -- Supreme National Security Council Secretary Hojatoleslam Hassan Rohani said on 30 April -- after the previous day's negotiations in London with British, French, and German representatives failed to yield substantive results -- Tehran is considering resumption of activities at the Isfahan uranium conversion facility (UCF).
February 2005 -- Iran and Russia sign an agreement on the return of spent nuclear fuel to Russia for reprocessing and storage. This measure is intended to eliminate the possibility that the materials will be used for making nuclear weapons. Fuel delivery will take place six months before the facility's completion, which should occur at the end of 2006.
January 2005 -- IAEA inspectors visit the Parchin military site, which is southwest of Tehran, to investigate allegations that the military tested conventional explosives that can be used to detonate nuclear weapons there.
December 2004 -- Talks between Iran and the EU-3 over political and economic concessions, in exchange for Iran making its enrichment suspension permanent, are scheduled to begin on 13 December (see "How Close Is Iran To The Bomb?").
November 2004 -- Iran holds talks in Paris with the EU-3. On 14 November, Iran signs an agreement to suspend uranium enrichment. The Europeans offer a series of political and economic concessions in exchange. But at an IAEA board of governors meeting from 25-29 November -- which was set to pass a resolution endorsing the deal and agreeing to monitor it -- Iran insists on an exemption for 20 centrifuges for research purposes. Iran eventually backs down, but demands -- and wins -- key changes softening the resolution in exchange. Most importantly, the resolution describes the enrichment freeze as a voluntary, rather than the legally binding commitment as both the United States and the EU sought. (See also, "The Iranian Nuclear Imbroglio.")
October 2004 -- The EU-3 again calls for Iran to suspend all uranium-enrichment activities to avoid its case being brought before the Security Council. The Europeans offer economic and political incentives in exchange. The Iranian parliament passes a bill approving the resumption of enrichment activities.
September 2004 -- An IAEA report calls Iran's claims about its nuclear program "plausible," but voices concern over Iran's decision to resume large-scale production of the feed material for enriching uranium. Claiming enrichment is a "sovereign right," Iran refuses to accept an unlimited suspension and says it will not stop manufacturing centrifuges. The IAEA gives Iran a 25 November deadline to reveal all its nuclear activities. Tehran later announces that it has resumed large-scale conversion of uranium yellowcake ore, a step toward uranium enrichment.
July 2004 -- Iran says it has resumed production of parts for centrifuges that are used for enriching uranium, but insists that it has not resumed its enrichment activities. The announcement appears to put the enrichment-freeze deal worked out between Iran, the EU-3, and the IAEA in jeopardy.
June 2004 -- IAEA says that inspectors found new traces of enriched uranium that exceeded the levels necessary for civilian energy production.
February 2004 -- Abdul Qadeer Khan, the founder of Pakistan's nuclear program, says that he had provided atomic secrets to Iran, Libya, and North Korea since the late 1980s. IAEA inspectors notice similarities in designs and components for the advanced P-2 centrifuge, adding to suspicions that Khan supplied both North Korea and Iran with same nuclear know-how.
November 2003 -- An IAEA report states that at the moment there is no conclusive proof that Iran is developing nuclear weapons. The United States, seeking to have the matter sent to the UN Security Council, dismisses the conclusion. The IAEA's 35-member board of governors passes a resolution sternly rebuking Iran for covering up 18 years of atomic experiments, but does not send the matter to the Security Council.
October 2003 -- The foreign ministers of France, Germany, and Great Britain travel to Tehran and persuade Iran to agree to stop enriching uranium and to sign the Additional Protocol to the NPT. The EU-3 also dangle economic concessions if Tehran cooperates fully with the IAEA. Iran turns over a declaration to the IAEA admitting to 18 years of covert atomic experiments, including the unreported uranium enrichment, although it continues to deny this was for a weapons program.
September 2003 -- The United States says Iran is in noncompliance with the NPT and calls for a referral to the UN Security Council, which could impose sanctions. But Washington agrees to support a proposal from Great Britain, France, and Germany (who were negotiating on behalf of the European Union and became known as the "EU-3") to give the Tehran until the end of October to fully disclose nuclear activities and allow for a stricter inspection regime.
July 2003 -- IAEA begins a fresh round of inspections in Iran.
June 2003 -- In a report, el-Baradei says inspections have demonstrated that "Iran failed to report certain nuclear materials and activities" and urges Tehran to cooperate with the agency. The report does not declare Iran in breach of the Nuclear Nonproliferation Treaty (NPT). The IAEA requests that Iran sign the Additional Protocol to the NPT and allow unannounced inspections of its nuclear sites.
February 2003 -- International Atomic Energy Agency (IAEA) Director-General Muhammad el-Baradei visits Iran to verify Tehran's claims that its nuclear program is peaceful. IAEA inspectors later find traces of highly enriched uranium at Natanz and other sites.
August 2002 -- An Iranian exile opposition group, the National Council of Resistance of Iran, accuses Tehran of hiding a uranium-enrichment facility at Natanz and a heavy-water plant at Arak.
