EXPLAINER-Iran's main nuclear centers, long in Israel's sights

After Iran's rocket attack on Israel on Tuesday, there is speculation that Israel could strike Iran's nuclear centers as it has actually long threatened to do.

Below are a few of Iran's main nuclear centers.

HOW CLOSE IS IRAN TO HAVING NUCLEAR WEAPONS?

Iran's nuclear programme is topped numerous places. While the threat of Israeli airstrikes has actually loomed for years, just some of the sites have been built underground. The United States and the U.N. nuclear watchdog think Iran had a coordinated, secret nuclear weapons program that it halted in 2003. The Islamic Republic denies ever having had one or preparing to have one.

Iran agreed to constraints on its nuclear activities in exchange for remedy for worldwide sanctions under a 2015 deal with world powers. That pact fell apart after then-President Donald Trump pulled out the United States in 2018 and Iran started deserting the constraints the next year.

Iran has been broadening its uranium enrichment program since, decreasing the so-called breakout time it would require to produce sufficient weapons-grade uranium for an a-bomb to a. matter of weeks from at least a year under the 2015 accord.

Really making a bomb with that material would take longer. For how long is less clear and the topic of argument. Iran is now enhancing uranium to approximately 60% fissile pureness, close. to the 90% of weapons grade, at 2 websites, and in theory it has. enough product enriched to that level, if improved further, for. nearly 4 bombs, according to a yardstick of the International. Atomic Energy Agency (IAEA), the U.N. watchdog.

NATANZ

A complex at the heart of Iran's enrichment programme on a. plain abutting mountains outside the Shi'ite Muslim holy city of. Qom, south of Tehran. Natanz houses facilities including 2. enrichment plants: the vast, underground Fuel Enrichment Plant. ( FEP) and the above-ground Pilot Fuel Enrichment Plant (PFEP).

A banished Iranian opposition group exposed in 2002 that. Iran was secretly developing Natanz, firing up a diplomatic. standoff in between the West and Iran over its nuclear intentions. that continues today.

The FEP was developed for enrichment on a commercial scale, able. to house 50,000 centrifuges. Around 14,000 centrifuges are. currently set up there, approximately 11,000 of which remain in. operation, refining uranium to up to 5% purity.

Diplomats with knowledge of Natanz describe the FEP as being. about 3 floorings below ground. There has long been debate. about how much damage Israeli airstrikes might do to it. Damage has been done to centrifuges at the FEP by other means,. consisting of an explosion and power cut in April 2021 that Iran. said was an attack by Israel. The above-ground PFEP houses only a few hundred centrifuges however. Iran is improving to up to 60% pureness there.

FORDOW

On the opposite side of Qom, Fordow is an enrichment website. went into a mountain and therefore probably much better secured from. prospective bombardment than the FEP.

The 2015 handle significant powers did not permit Iran to enhance. at Fordow at all. It now has more than 1,000 centrifuges. operating there, a fraction of them advanced IR-6 makers. improving to approximately 60%. In addition, Iran recently doubled the number of centrifuges. set up at Fordow, with all the brand-new ones being IR-6 machines.

The United States, Britain and France revealed in 2009 that. Iran had been secretly building Fordow for many years and had actually stopped working. to inform the IAEA. U.S. President Barack Obama said then: The. size and setup of this center is inconsistent with a. peaceful programme.

ISFAHAN

Iran has a big nuclear technology centre on the borders. of Isfahan, its 2nd biggest city. It consists of the Fuel Plate Fabrication Plant (FPFP) and the. uranium conversion center (UCF) that can process uranium into. the uranium hexafluoride that is fed into centrifuges.

There is devices at Isfahan to make uranium metal, a. process that is particularly proliferation-sensitive given that it. can be used to devise the core of a nuclear bomb. The IAEA has actually said there are makers for making centrifuge parts. at Isfahan, explaining it in 2022 as a brand-new place.

KHONDAB

Iran has a partly developed heavy-water research study reactor. originally called Arak and now Khondab. Heavy-water reactors. position a nuclear expansion danger because they can easily. produce plutonium which, like enriched uranium, can be utilized to. make the core of an atom bomb. Under the 2015 deal, building and construction was stopped, the reactor's core. was eliminated and filled with concrete to make it unusable. The. reactor was to be redesigned to minimise the production of. plutonium and not to produce weapon-grade plutonium in typical. operation. Iran has notified the IAEA that it prepares to bring. the reactor online in 2026.

TEHRAN RESEARCH CENTRE

Iran's nuclear research facilities in Tehran consist of a. research reactor.

BUSHEHR

Iran's only operating nuclear reactor, on the Gulf. coast, uses Russian fuel that Russia then takes back when it is. spent, lowering the expansion danger.
