Iran may ‘give assurances on the use of nuclear facilities

Iran has indicated a willingness to provide assurances regarding the use of its nuclear facilities, though it maintains it will not destroy its stockpiles of uranium or allow the material to be moved out of the country. The position, reported on May 10, 2026, suggests a narrow window for diplomatic negotiation regarding the nature of Iran’s nuclear program while asserting a hard line on the retention of its nuclear assets.

The distinction between the use of facilities and the ownership of nuclear material is central to the ongoing diplomatic tension between Tehran and international monitors. By offering assurances on the use of facilities, Iran may be signaling a readiness to discuss transparency measures or limits on how its centrifuges are operated, without conceding the material it has already enriched.

The refusal to destroy or relocate uranium is a significant point of contention. In previous nuclear agreements, the removal or destruction of enriched uranium was a primary requirement to increase the time required for a state to produce enough weapons-grade material for a nuclear device, a period known as the breakout time.

The Role of Uranium Stockpiles

Uranium enrichment is the process of increasing the concentration of the isotope uranium-235. For civilian nuclear power, uranium is typically enriched to between 3 percent and 5 percent. However, higher levels of enrichment are required for research reactors, and levels above 90 percent are necessary for nuclear weapons.

Iran’s insistence on keeping its uranium suggests it views the stockpiles as both a strategic deterrent and a domestic asset for energy and medical research. The movement of such material is strictly regulated under international law and the safeguards of the International Atomic Energy Agency (IAEA), the United Nations’ autonomous organization for nuclear energy.

International negotiators have frequently pushed for the shipment of enriched uranium to third-party countries or its dilution to a level where it can no longer be easily used for weapons. Iran’s explicit rejection of these options on May 10, 2026, indicates that any potential new agreement would have to find a way to manage the existing stockpiles in situ.

Assurances and International Monitoring

The offer to give assurances on the use of nuclear facilities likely refers to the level of access granted to IAEA inspectors. The IAEA is responsible for verifying that nuclear programs remain peaceful. This involves the installation of surveillance cameras, the sealing of equipment, and the regular sampling of environmental material to detect undeclared nuclear activities.

Tensions have persisted over the IAEA’s ability to monitor Iran’s facilities, particularly after the 2018 withdrawal of the United States from the Joint Comprehensive Plan of Action (JCPOA), the 2015 agreement that limited Iran’s nuclear activities in exchange for sanctions relief.

Since the JCPOA’s effective collapse, Iran has increased its enrichment levels and expanded its centrifuge arrays. Assurances on the use of these facilities could involve a return to stricter monitoring protocols or a commitment to cap enrichment levels at a specific percentage, provided that the existing uranium remains under Iranian control.

Regional and Global Implications

The nuclear standoff involving Iran has broad implications for security in the Middle East. Regional powers, particularly Israel and Saudi Arabia, have expressed concerns that Iran’s ability to maintain high levels of enriched uranium brings the region closer to a nuclear arms race.

The United States and the European Union have historically utilized a combination of economic sanctions and diplomatic pressure to limit Iran’s nuclear capabilities. The current stance taken by Tehran on May 10, 2026, places the burden of compromise on international negotiators to accept the presence of uranium stockpiles in exchange for operational transparency.

Diplomatic observers note that the refusal to move uranium is often tied to Iranian concerns over sovereignty and the fear that once material is exported, it cannot be recovered, effectively stripping the country of its nuclear leverage.

The current status of the negotiations remains precarious. While the offer of assurances provides a potential starting point for dialogue, the fundamental disagreement over the physical existence and location of enriched uranium remains a primary obstacle to a comprehensive nuclear settlement.
