The NPT and IAEA safeguards

The objective of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is to prevent the spread of nuclear weapons, promote international cooperation in the peaceful uses of nuclear energy and further the goal of achieving nuclear disarmament, as well as general and complete disarmament.

The NPT was opened for signature on 1 July 1968 and entered into force on 5 March 1970. The operation of the Treaty is reviewed every five years at the Review Conference of the Parties to the NPT. On 11 May 1995, the NPT Review and Extension Conference decided to extend the Treaty indefinitely.

The Treaty has 191 Parties, including 186 non-nuclear-weapon States (NNWSs) and 5 nuclear-weapon States (NWSs): China, France, the Russian Federation, the United Kingdom and the United States of America.

The IAEA is not a Party to the NPT. However, under Article III of the Treaty, the IAEA administers international safeguards to verify that NNWSs party to the NPT fulfil the non-proliferation commitments they have made under the Treaty, “with a view to preventing diversion of nuclear energy from peaceful uses to nuclear weapons or other nuclear explosive devices.” Through its independent verification work, the IAEA plays an indispensable role in the implementation of the Treaty and the prevention of the spread of nuclear weapons.

IAEA safeguards

The establishment and administration of safeguards is one of the main functions of the IAEA under its Statute, which entered into force in 1957. The Statute authorizes the IAEA to “apply safeguards, at the request of the parties, to any bilateral or multilateral arrangement, or at the request of a State, to any of that State’s activities in the field of atomic energy.”

The IAEA concluded its first safeguards agreement in 1959, long before the NPT entered into force. Since then, both the IAEA legal framework for safeguards and the implementation of safeguards have evolved. This is mainly due to the entry into force of multilateral treaties requiring IAEA safeguards (see here), as well as advances in nuclear technology, technological developments in the field of safeguards, practical experience gained by the IAEA from the implementation of safeguards, and the need to strengthen the effectiveness and improve the efficiency of safeguards.

Before 1971, when the first comprehensive safeguards agreements (CSA) with an NNWS in connection with the NPT was concluded, the IAEA had implemented safeguards for 32 States under item-specific safeguards agreements.

Since June 1971, 178 NNWSs party to the NPT have brought into force CSAs with the IAEA, and 8 NNWSs have yet to do so. All five NWSs party to the NPT have concluded voluntary offer agreements with the IAEA. Three countries that are not Party to the NPT, India, Israel and Pakistan, have item-specific safeguards agreements in force with the IAEA.

The implementation of safeguards under CSAs between 1971 and 1991was focused mainly on the verification of nuclear material and facilities declared by States. The IAEA’s safeguards experience in Iraq and the Democratic People’s Republic of Korea in the early 1990s demonstrated that the IAEA’s capabilities to detect undeclared nuclear material and activities were limited. Since 1991, several measures have been adopted by the Board of Governors to strengthen the effectiveness and improve the efficiency of IAEA safeguards.

The most important development was the approval of the Model Additional Protocol by the Board of Governors in 1997. Additional protocols (APs) contain important measures that significantly increase the IAEA’s ability to detect undeclared nuclear material and activities in a State with a CSA. Since May 1997, 138 States party to the NPT have brought into force APs, including the 5 NWSs.

The IAEA’s safeguards responsibilities and workload have increased steadily since 1971. By the end of 2020, the IAEA had applied safeguards for 184 States, including 181 States party to the NPT (176 NNWSs and 5 NWSs); and more than 1300 nuclear facilities and locations were under IAEA safeguards. In 2020, IAEA inspectors conducted more than 3000 inspections in the field.

IAEA safeguards and the NPT Review Conference

From the very beginning of the NPT review process, State Parties expressed strong support for effective IAEA safeguards.

The first Review Conference in 1975 noted that “the verification activities of the IAEA under Article III of the Treaty respect the sovereign rights of States and do not hamper the economic, scientific or technological development of the Parties to the Treaty or international co-operation in peaceful nuclear activities” and recommended that “intensified efforts be made towards the standardization and the universality of application of IAEA safeguards.”

The 1995 NPT Review and Extension Conference affirmed that nothing should be done to undermine the verification authority of the IAEA and stressed that IAEA safeguards should be regularly assessed and evaluated. It also affirmed that decisions adopted by its Board of Governors aimed at further strengthening the effectiveness of IAEA safeguards should be supported and implemented and the IAEA’s capability to detect undeclared nuclear activities should be increased.

The 2010 Review Conference called upon all State Parties to “ensure that IAEA continues to have all political, technical and financial support so that it is able to effectively meet its responsibility to apply safeguards as required by article III of the Treaty,” and encouraged State Parties, within the framework of the IAEA Statute, to “further develop a robust, flexible, adaptive and cost-effective international technology base for advanced safeguards through cooperation among Member States and with IAEA.”
