Iran has several research sites, two uranium mines, a research reactor, and uranium processing facilities that include three known uranium enrichment plants.^[1]

Commencing in the 1950s with support from the United States (under the Atoms for Peace program), Iran's nuclear program was initially geared toward peaceful scientific exploration. In 1970, Iran ratified the Non-Proliferation Treaty (NPT), subjecting its nuclear activities to IAEA inspections. After the 1979 Iranian Revolution, cooperation ceased and Iran pursued its nuclear program clandestinely.

An investigation by the IAEA was launched as declarations by the National Council of Resistance of Iran in 2002 revealed undeclared Iranian nuclear activities.^[2][3] In 2006, Iran's noncompliance with its NPT obligations moved the United Nations Security Council to demand Iran suspend its programs.

In 2007, the United States National Intelligence Estimate (NIE) stated Iran halted an alleged active nuclear weapons program in 2003.^[4] In November 2011, the IAEA reported credible evidence that Iran had been conducting experiments aimed at designing a nuclear bomb, and that research may have continued on a smaller scale after that time.^[5][6] On 1 May 2018 the IAEA reiterated its 2015 report, saying it had found no credible evidence of nuclear weapons activity after 2009.^[7][8][9]

Operational since September 2011, the Bushehr I reactor marked Iran's entry into nuclear power with Russia's assistance. This became an important milestone for Rosatom to become the largest player in the world nuclear power market.^[10] Anticipated to reach full capacity by the end of 2012, Iran had also begun constructing a new 300 MW Darkhovin Nuclear Power Plant and expressed plans for additional medium-sized nuclear power plants and uranium mines in the future.

Despite the 2015 Joint Comprehensive Plan of Action (JCPOA) aimed at addressing Iran's nuclear concerns, the U.S. withdrawal in 2018 prompted renewed sanctions, impacting diplomatic relations. The IAEA certified Iran's compliance up until 2019, but subsequent breaches strained the agreement.^[11][12] In a 2020 IAEA report, Iran was said to have breached the JCPOA and faced criticism from signatories.^[13][14]

In 2021, Iran faced scrutiny regarding its assertion that the nuclear program was exclusively for peaceful purposes, especially with references to growth in satellites, missiles, and nuclear weapons.^[15]

In April 2022, Atomic Energy Organization of Iran head Mohammad Eslami announced a strategic plan for 10 GWe of nuclear electricity generation.^[16]

In October 2023, an IAEA report estimated Iran has increased its uranium stockpile twenty-two times over the 2015 agreed JCPOA limit.^[17]
