Lithuania actively participates in all the processes of Nuclear Security Summits, aiming to contribute to the global effort of strengthening nuclear security, and to support and engage in the initiatives to build national and international capacities in order to prevent illicit trafficking in nuclear and other radioactive material.
During the second Nuclear Security Summit held in Seoul, the capital city of South Korea, on 26–27 March 2012, the President of the Republic of Lithuania, H. E. Dalia Grybauskaitė presented a national report and the practical contribution of Lithuania to counteract illicit trafficking in nuclear material. The President officially stated that NSCOE would be established in Lithuania to develop competent human resources and contribute to the strengthening of nuclear security capabilities.
NSCOE was established in April 2012 within the State Border Guard Service. NSCOE activity goals and its remit were determined during consultations and negotiations between Lithuanian Government agencies, international organisations, and foreign partner states. Recommendations of the International Atomic Energy Agency (IAEA) on establishing nuclear security support centres were used for establishing NSCOE.
Since 2016, the NSCOE has been assigned with new functions therefore the scope of its activities increased significantly:
- Nuclear security training program development and implementation
- Contribution to the development of the national nuclear security capabilities including coordination and collaboration between competent authorities
- Radiation detection infrastructure development and instrumentation life-circle maintenance and repair management
- Radiation detection at the points of entry coordination, management and control
- Coordination of the physical protection activities at the nuclear infrastructure
