IAEA and Nuclear Security: An Evolutionary Perspective

Since 1957, the International Atomic Energy Agency (IAEA) has expanded its role in nuclear security. While it was only intended to focus on promoting the peaceful use of nuclear energy in line with safeguards implementation to prevent nuclear proliferation, its mandate has, in time, evolved to address the emerging threats to nuclear technology, i.e., nuclear terrorism and illicit trafficking of nuclear materials. In this historical perspective, the article analyses the development of the IAEA's nuclear security framework. Over time, there have been key points, such as the need for physical protection in the 1970s and the establishment of comprehensive security measures after the 9/11 terrorist attacks. Currently, the IAEA's nuclear security program consists of guidance, training, and international cooperation efforts, which are only available upon the request of Member States. More recently, it has expanded its nuclear security efforts to provide technical assistance and monitor nuclear safety and security in conflict zones. However, this expansion has not been easy for the IAEA as it has challenges such as funding limitations and the tension between national sovereignty and international oversight. Ultimately, the IAEA's nuclear security role as the global platform shows its critical importance in enhancing international efforts to mitigate nuclear security threats. However, while the IAEA has made important progress in nuclear security, structural and political limitations constrain its effectiveness.
