According to Mars Finance, on June 13, early signs indicate that Israel's attacks did not penetrate the protective layer safeguarding Iran's nuclear storage facilities. The International Atomic Energy Agency (IAEA) stated that there are no signs of increased radiation levels at Iran's main uranium enrichment facilities. Iranian authorities informed the IAEA that they have not observed higher radiation levels at the Natanz facility, located about 300 kilometers south of Tehran. Israeli authorities claim that Israel has not carried out any attacks on the Bushehr nuclear power plant located on the Persian Gulf coast. Nevertheless, Israeli Prime Minister Netanyahu stated that the attacks 'will continue for several days until this threat is eliminated.' Only the most powerful conventional munitions can penetrate Iran's uranium enrichment facilities. The Natanz nuclear facility is built more than 40 meters underground, protected by a reinforced concrete shell, which researchers estimate to be about 8 meters thick. In the Fordow nuclear facility, the enrichment hall is built into a mountainside. After a recent visit, IAEA Director General Grossi estimated that the uranium enrichment hall is located half a kilometer underground. (Jinshi)
