Effective nuclear security regime assigns specific functions and responsibilities to the different institutions at the same time, this should be supported by significant investments – human and financial. This is a crucial condition enabling those institutions to develop nuclear security capabilities.

However, when capabilities are developed, the next important goal is to sustain competent authorities’ capabilities to prevent, to detect and to respond to the nuclear security event.

Nuclear security sustainability is a set of measures designed to ensure effective nuclear security regime over the long term. Such sustainability measures are implemented at both national and institutional levels.

The IAEA-formulated concept of nuclear safety sustainability (IAEA publication NSS 30-G) is presented:


The key features (principles) a sustainable nuclear security regime are as follows:

  1. Recognition of the importance of a nuclear security regime on the national level and the commitment to develop and implement the national nuclear security regime;
  2. Based on the provisions of international legal instruments, development of legal basis that governs the implementation of the national nuclear security regime;
  3. Designation of responsible authorities, allocating the relevant resources required to meet their objectives and maintaining their motivation;
  4. Regular assessment of nuclear security threats and utilization of the risk-informed approach while developing and implementing nuclear security measures;
  5. Implementation of the of interagency cooperation and coordination mechanism in order to prevent systematic gaps and to ensure efficient use of resources and to avoid duplication of efforts;
  6. Continuous development of human resources to meet needs for competent staff within authorities implementing measures of the nuclear security regime;
  7. Long-term programs for deployment, enhancing, maintenance and repairs of specialized technical equipment aimed at ensuring its long-term availability and effectiveness;
  8. Robust nuclear security culture when responsible authorities consistently develop employees’ attitudes, principles and behaviors required for motivated and efficient professional performance;
  9. Periodical evaluation of the effectiveness of the nuclear security measures and identification of the areas for improvements.

The mission of the Nuclear Security Centre of Excellence is to support the sustainability of the national nuclear security capabilities ensuring that they remain effective and correspond needs and requirements over a longer time. Specifically, the NSCOE provides sustainability services to stakeholders’ organizations that are necessary for building and implementing their nuclear security functions.

The main NSCOE activities in the area of nuclear security sustainability: 

  • Personnel initial and continuous training;
  • Training instructors development;
  • Exercise development and implementation;
  • Participation in developing plans, procedures, instructions;
  • Compliance evaluations;
  • Participation assessing risks and threats;
  • Detection technical equipment deployment, maintenance and repair.
