Iran’s Arak Heavy Water Nuclear Facility was damaged by Israeli bombing

Israel’s assault regarding Iran’s nuclear activities has raised concerns about potential radioactive incidents, according to experts, including the director of the International Atomic Energy Agency (IAEA). New Scientist While there have been reports of radiological and chemical contamination at one nuclear enrichment facility, the overall risk remains low.
Peter Bryant from the University of Liverpool notes that the terms “nuclear” and “radiation” understandably provoke fear, but despite extensive bombings, there have been no reported external leaks as of now.
Iran’s nuclear ambitions trace back to the 1950s, including attempts to develop nuclear weapons. The country pledged to allow IAEA inspections to verify that its energy facilities are not being utilized for weapon production; however, the agency recently issued a report criticizing Iran for failing to comply with non-proliferation obligations. Evidence of uranium traces at certain plants suggests that a covert nuclear weapons program might still be in progress.
Following reports regarding Iranian facilities responsible for uranium enrichment, Israel launched its strikes. Naturally occurring uranium exists in a mixture of three isotopes, but the enriched variant has a greater proportion of uranium-235, which can be used for both electrical generation in reactors and for nuclear arms. Given this dual-purpose potential, Iran has committed to restricting enrichment under the Treaty on the Non-Proliferation of Nuclear Weapons.
Philip Bleak from the Middlebury International Institute in California points out that the IAEA reports indicate Iran has already accumulated over 400 kilograms of uranium concentrated to 60%. This quantity is adequate for multiple rudimentary nuclear weapons, and Israeli intelligence suggests that the actual figures may be underreported to the IAEA. Even uranium at 60% purity significantly exceeds the requirements for fueling a power plant, implying that Iran harbors intentions to develop nuclear capabilities.
Iran maintains two primary enrichment sites: the Fordow Fuel Enrichment Plant (FFEP) and the Natanz Nuclear Facility. Israel’s strikes on Natanz resulted in internal radiation leaks; however, according to the IAEA, there have been no signs of external contamination.
In contrast, the Fordow facility remains operational due to its underground location, making it susceptible to destruction only by powerful US munitions. Only a powerful US bomb could destroy it. Former President Donald Trump has indicated he might assess support for Israel in this matter.
The Arak Heavy Water Reactor has also been targeted in bombings; however, it was never commissioned and housed no radioactive substances. If operational, it could have enabled the conversion of uranium into plutonium, a material viable for nuclear weaponry. Additionally, the Isfahan Nuclear Technology Center and certain missile sites designed for nuclear weapons launch were also bombed.
Bleak asserts that fresh uranium poses “very modest” health risks irrespective of enrichment levels. “A significant amount must enter your body to have a meaningful impact, similar to what uranium miners experienced,” he explains.
This is why the enrichment facilities targeted in strikes represent minimal risk outside their immediate vicinity, according to Bryant. Moreover, since these plants are built deep underground for resistance against attacks, any radioactive emissions would be further contained. “Uranium fuel can be handled without issue,” states Bryant. “You would need to physically ingest it to face health problems.”
Nonetheless, should a working reactor be targeted and operational for months prior to an attack, it may accumulate “dangerous fission byproducts,” which represent a more significant radiological threat. Bleak warns that if such materials escape, scenarios akin to Chernobyl or Fukushima could arise.
Bryant expresses confidence that such leaks are exceedingly unlikely, attributing this to advancements in reactor design that can withstand heavy bombardments. Furthermore, civilian power plants are not core to Iran’s nuclear weapons program and are unlikely to be prioritized targets for Israel, he says. Bushehr, Iran’s only functioning nuclear power facility, has not been targeted thus far.
Despite assurances from scientific experts, New Scientist reports that IAEA Director Rafael Grossi cautioned earlier this week about the real risks of harm.
“I have consistently stated that we should never attack nuclear facilities, irrespective of the circumstances, as they can pose hazards to both humanity and the environment,” he asserted.
