NSSCs contribute to sustaining the national nuclear security regime by supporting competent authorities, authorized persons, and other organizations with nuclear security responsibilities. Main NSSC functions are:
- Human resource development, specifically through the provision of a national nuclear security training programme;
- Technical support services for nuclear security equipment lifecycle management; and
- Scientific support services for provision of expertise, analysis, and research and development for nuclear security.
The Centres also foster nuclear security culture and enhance national coordination and collaboration among organizations involved in nuclear security. The IAEA Technical Document titled Establishing and Operating a National Nuclear Security Support Centre (Revision of IAEA-TECDOC-1734) outlines the role of NSSCs in sustaining nuclear security and details a step-by-step, systematic process for establishing an NSSC and ensuring its effectiveness over the long term.
