The Bushehr Nuclear Power Plant (BNPP) is Iran's first commercial nuclear reactor. In 1994, Tehran and Moscow signed an agreement to construct the VVER 1000MWe light-water reactor, and construction started the same year. [1]

Iran had previously attempted to build a nuclear power plant at the Bushehr site, and in 1974 contracted the German company Siemens (then KraftWerk) to build two reactors. The first unit was approaching completion when Iran halted the project as a result of the 1979 Iranian revolution. [2] During the Iran-Iraq war, the reactors sustained severe damage in an Iraqi bombing raid. [3] After the war Siemens refused to continue with construction in the face of extreme diplomatic pressure from the United States.

The Bushehr Nuclear Power Plant is unique in design because Russia agreed to incorporate its VVER technology into the original German-built infrastructure. [4] In a series of shipments between December 2007 and January 2008, Iran received a total of 82 tons of fuel from Russia for the initial fuel loading of the BNPP. [5] The IAEA has arranged to verify and seal the fresh fuel shipments, and all of the fuel assemblies imported from Russia for use at the Bushehr plant remained under Agency seal before being loaded into the reactor. [6] Iran is required to return spent fuel rods from Bushehr to Russia as soon as they are safe for transport. [7] Indicating that the plant was nearing completion, engineers conducted a series of pre-start tests in 2009 and 2010. [8]

Loading of fuel into the reactor core was finished in November 2010. [9] However, in February 2011 Iran informed the IAEA that the fuel would have to be removed. [10] A broken pump had caused small metal particles to infiltrate the reactor's cooling system, and it was feared that the particles might have made their way into the fuel assemblies. [11] It was speculated that the Stuxnet computer virus had caused damage to the facility. [12] In April 2011, the fuel was reloaded into the reactor. [13] The following month, the Bushehr plant began operating at low levels. [14] On 11 February 2012 the plant was connected to the national grid, generating 700 megawatts of electricity. That same month, Iranian Atomic Energy Organization chief Fereydoun Abbasi-Davani announced that the plant would operate at full capacity starting in late March 2012. [15]
 

In 2013, a 6.3 magnitude earthquake hit the southwest region of Iran, where Bushehr is located.[16] Given that much of Iran is in a seismic zone, many expressed concerns over BNPP's safety following the earthquake. For example, the United Arab Emirates and Saudi Arabia voiced concerns at the IAEA Board of Governors meeting in June 2013.[17] Iran denied allegations concerning the plant's safety "vulnerability."[18] Simultaneously, Iran reported an electric generator malfunction and "long cracks […] in at least one section of the structure." However, Tehran dismissed the suggestion that the malfunction was connected to the earthquake.[19] The IAEA's May 2013 report indicated that the reactor was shut down during its inspections on 11 and 12 May 2013.[20] IAEA Director General Yukiya Amano later stated that the IAEA had no information regarding the causes of the plant's shutdown. The IAEA’s 12 August 2013 inspection of the Bushehr Nuclear Power Plant indicated that the reactor is operating at 100% of its nominal power.[21]

On 24 November 2013, the P5+1 talks in Geneva resulted in a Joint Plan of Action. The Plan is described as the first step toward ensuring that Iran’s nuclear program will be exclusively peaceful. The agreement outlines voluntary steps that Iran must fulfill within a six month period, in return the P5 have agreed to temporarily ease economic sanctions targeting the Iranian nuclear program. During this time period, The IAEA will have 24 hour access to the Bushehr Nuclear Power Plant for inspections.[22]
