There are a number of nuclear threads to the unfolding situation in Syria:
Russia has warned that a missile strike on Syria could have catastrophic effects if it hits a research reactor near Damascus.[1] "If a warhead, by design or by chance, were to hit the Miniature Neutron Source Reactor [MNSR] near Damascus, the consequences could be catastrophic," a September 5 statement by the Russian Foreign Ministry said. The statement calls on the IAEA to "react swiftly" and present IAEA members with "an analysis of the risks linked to possible American strikes on the MNSR and other facilities in Syria". The statement said nearby areas could be contaminated by highly enriched uranium and that it would be impossible to account for the nuclear material after such a strike.
Ambassador Bassam Al-Sabbagh, a senior Syrian diplomat, said on September 10 that he had voiced his nation's "deep concern" to IAEA Director General Yukiya Amano about the possible risks of a military strike on the MNSR. Al-Sabbagh said Syria "strongly" endorsed the Russian request for an assessment by IAEA: "I expressed our deep concern regarding the possible risks of any military attack on facilities under safeguards agreement."[2]
The US Ambassador to the IAEA, Joseph Macmanus, told an IAEA Board meeting on September 9 that such "comprehensive risk analyses of hypothetical scenarios are beyond the IAEA's statutory authority. The IAEA has never before conducted this type of analysis, and it would exceed IAEA's mandate, and have far-reaching implications that exceed IAEA capabilities and authorities."[3]
Amano said on September 9 that the IAEA was considering the Russian request.[4,5] He said that 1 kg of highly enriched uranium (HEU) is contained in the MNSR.[6] The HEU fuel is enriched to nearly 90% according to an IAEA document.[4]
Mark Hibbs from the Carnegie Endowment for International Peace said the MNSR is a very small reactor but there could be "a serious local radiation hazard" if there was irradiated nuclear material in the reactor and it was dispersed by a military strike.[1]
Amano noted that additional radiological materials could be in storage at multiple Syrian medical and scientific facilities.[7] Former IAEA safeguards chief Olli Heinonen said Syria "should have substantial amounts" of atomic assets such as radioactive cobalt isotopes. Such holdings could be "of a greater concern, if they end up in wrong hands," Heinonen said. "Normally they are stored in protected vaults."[7]
2007 Israeli strike
On 6 September 2007, Israel bombed a desert site in Syria that US intelligence reports said was a partially completed 25MW(t) North Korean-designed gas-cooled graphite-moderated reactor, which would have been capable of producing enough plutonium for one or two weapons per year. Syria said the site was a conventional military facility.[12]
Echoing responses to Israel's strike on a research reactor in Iraq in 1981, then IAEA Director-General Mohamed El Baradei said in response to the 2007 strike: "If a country has information that another country is developing a secret nuclear program, the IAEA should be contacted because we have the power to investigate the issue."[8]
The IAEA released its latest report on this matter in late August − though it adds little to previous reports.[9] The latest IAEA report states that:
Furthermore, IAEA inspectors discovered undeclared anthropogenic uranium particles at the MNSR in 2008 and 2009. The investigation is ongoing, but the most recent information provided by Syria indicates that the particles originated from previously unreported activities involving the conversion of yellowcake to uranyl nitrate in 2004.[10]
Historical pursuit of nuclear facilities
According to the Nuclear Threat Initiative (NTI), Syria has consistently pursued more advanced nuclear technologies.[10] The military has been a stakeholder in Syria's nuclear program since the 1970s, and Damascus has both openly and covertly sought the assistance of numerous parties, including the IAEA, China, Russia, Iran, and North Korea to develop its nuclear program.
The NTI notes that Syria is a very long way short of a nuclear weapons capability: it has a weak industrial infrastructure; poor scientific capabilities; lacks the trained engineers and other personnel needed to run a major civilian or weapons-oriented program; the MNSR yields only tiny quantities of plutonium in its spent fuel, while its highly enriched uranium fuel is insufficient in quantity for a nuclear weapon; and Syria has not developed full nuclear fuel-cycle expertise and is not known to possess reprocessing technologies.
Previous efforts to procure nuclear technology include the following:[8,10,11]
Suspected fuel development site
A report released by the Institute for Science and International Security (ISIS) on September 12 said that ancillary facilities built to support the alleged Syrian reactor could still contain uranium and other material of potential value to terrorist groups or black-market profiteers. The Marj as Sulţān facility in Damascus may have been involved in developing reactor fuel for the reactor. The reactor would have needed about 50 tonnes of natural uranium fuel to operate.[13]
"The uranium could be anywhere within government controlled areas today, if it even remains in Syria," the ISIS report states. "Determining its fate must be a priority."
The report notes that any uranium fuel remaining in Syria is not weapons-grade and could not be used in nuclear bombs without further processing. While Syria's thousands of chemical weapons remain a higher priority, its nuclear assets "deserve significant attention". Syria also has radioactive sources and wastes which could be at risk of seizure, the ISIS report states, and these could cause greater radioactive harm than natural uranium.
Syria is not believed to have an active, secret nuclear program at this time, the ISIS report states, but it is believed to be actively hiding assets associated with its past, undeclared nuclear reactor effort. Both the Marj as Sulţān fuel development site and the (now demolished) reactor site have fallen under control of government opponents at times during the civil war. Rebels reportedly invited the IAEA to inspect the reactor site if they satisfied some unspecified conditions. The IAEA did not take up this offer, and it would have had no authority to do so, since its safeguards agreement is with the Syrian government. The UN would need to provide the IAEA with authority (and adequate protection) to inspect the site independent of the Syrian government, the ISIS report states.
