Iran's Missing Uranium: Nuclear Worries Amidst Conflict

Unaccounted Nuclear Material

• ⚠️ Iran's highly enriched uranium, totaling 409 kg, is unaccounted for after UN nuclear monitors lost track of it following Israeli bombing on June 13th.
• 🎯 This material, if further enriched to 90%, is equivalent to the amount needed for approximately 10 nuclear weapons.
• 📍 The uranium was last seen stored in underground tunnels at the Isfahan complex, but its current location is unknown.

Loss of Verification and Iranian Actions

• 🚫 International Atomic Energy Agency (IAEA) inspectors were unable to verify the material's location due to the bombing, which halted normal inspections.
• 📜 Iranian diplomats had previously informed the IAEA that they would move the material to an undeclared location if attacked.
• 📉 The IAEA has lost visibility on the nuclear material inventory for about 10 days, compounding concerns.
• 🚨 Iran is also restricting IAEA movements and has threatened to leave the nuclear non-proliferation treaty, which would end IAEA inspections.

Transportability and Handling

• 🧳 The highly enriched uranium is transportable in canisters about the size of a scuba tank, each carrying approximately 25 kg.
• 🚗 This means an individual or a small vehicle could move the material to an undisclosed location.
• 🛠️ Handling enriched uranium is not complicated; the radiological risk arises after irradiation in a reactor or bomb.

Pre-Conflict Monitoring and Disputes

• ✅ Before the bombing, the IAEA had a good grasp on Iran's declared nuclear material, including thousands of kg of lower-enriched uranium.
• 🔍 The dispute prior to the bombing was over trace elements of uranium detected at undeclared sites, which Iran refused to fully cooperate on investigating.
• ⚖️ Iran considered its cooperation leading up to the 2015 nuclear agreement sufficient and was not obligated to continue cooperating on old investigations.

Future of Nuclear Diplomacy

• 📉 The potential withdrawal from the NPT by Iran is a massively escalatory move, especially in light of the recent conflict.
• ⏳ Even if inspections resume, it will take years for the IAEA to reestablish a baseline and rebuild data on Iran's stockpile due to localized hazards and the need to start from scratch.
• 🌐 This situation presents a complex challenge to the global non-proliferation regime.
