The International Atomic Energy Agency (IAEA) reported on the 14th (local time) that while a major nuclear facility in Isfahan, central Iran was destroyed by an Israeli airstrike, no radiation was released to the outside.

On this day, IAEA stated through X (formerly Twitter) that "four major buildings, including the uranium conversion facility and fuel plate manufacturing plant in Isfahan, were destroyed by the Israeli airstrike the previous day." The uranium conversion facility is a key system that converts uranium into a gaseous state for enrichment processes.

IAEA added that "similar to Natanz (which was destroyed in the Israeli airstrike), there is expected to be no increase in external radiation levels in Isfahan."

Natanz and Isfahan are key nuclear development sites in Iran. The Israeli military focused its airstrikes on the two locations the previous day. IAEA stated that while radiation and chemical contamination were detected inside the Natanz nuclear facility, there was no external radiation leak.

It is reported that about 400 kg of 60% enriched uranium, which is just one step away from weaponization, is stored at the Natanz nuclear facility. Iran is the only country among those without nuclear weapons that produces enriched uranium.

Rafael Mariano Grossi, the IAEA Director General, expressed "great concern" over the Israeli attack on Iran's nuclear facilities, stating that "attacks on civilian nuclear facilities must never be tolerated under any circumstances."
