Convention on Physical Protection of Nuclear Material (CPPNM) and Amendment thereto


The Convention on the Physical Protection of Nuclear Material entered into force on 8 February 1987. The Convention is the only legally binding international instrument in the area of physical protection of nuclear material and one of the 13 international counter-terrorism instruments. It establishes measures related to the prevention, detection and punishment of offenses related to nuclear material. status

On 8 July, 2005, States Parties to the CPPNM adopted by consensus an Amendment to the CPPNM. Whereas the obligations for physical protection under the CPPNM covered nuclear material during international transport, the Amendment to the CPPNM makes it legally binding for States Parties to protect nuclear facilities and material in peaceful domestic use, storage and transport. It also provides for expanded cooperation between and among States regarding rapid measures to locate and recover stolen or smuggled nuclear material, mitigate any radiological consequences of sabotage, and prevent and combat related offences. status

The Amendment will enter into force when it has been ratified by two-thirds of the States Parties of the Convention. The Amendment constitutes an important milestone in international efforts to improve the physical protection of nuclear material and facilities. The Amendment is vitally important for nuclear security and will have a major impact in reducing the vulnerability of States Parties to nuclear terrorism.

The General Conference has appealed to all States that have not yet done so to adhere to the CPPNM as soon as possible.

The IAEA’s Board of Governors and General Conference have both encouraged all States Parties to ratify the Amendment and to act in accordance with its object and purpose pending its entry into force.
