The Korea Institute of Nuclear Nonproliferation and Control (KINAC) conducts various outreach activities, such as publishing brochures and holding seminars and briefings, to make regulated parties aware of the importance and necessity of the export control regime. The outreach program aims to increase compliance rates by generating interest in the export control regime among recipients and to increase communication to support compliance. In order to explore the long-term development of outreach activities, we analyze how KINAC conducts outreach. KINAC conducts nuclear export control outreach to organizations that deal with trigger list items and related technologies. Educational institutions with nuclear energy-related departments, research institutes related to nuclear energy and materials, and industrial companies that handle equipment used in nuclear power plants or nuclear materials were selected for outreach. The outreach program provides information on the export control regime for trigger list items, the strategic technology control regime, and the Nuclear Cooperation Agreement. KINAC’s outreach programs can be categorized into education, exhibition, and publication. In the education program, we hold workshops and seminars for industrial companies, with customized content that considers the items handled by companies and the nature of technology transfer. We provide training for educational and research institutions focused on conducting research tasks and projects and transferring technology accordingly. As a result of the education program, there is a regret that the education for SMEs and educational institutions is not directly linked to the implementation of nuclear export control. The exhibition program operated a booth at nuclear-related exhibitions at least once a year. The booth distributed brochures or publications on the export control regime, conducted surveys to investigate awareness of the regime and conducted on-site consultations. The exhibition program effectively increased the understanding of the export control regime among the general public and potential regulated parties. However, it was only sometimes linked to the actual implementation of nuclear export control. The publication program produced promotional materials for use at education and exhibitions, as well as guidance materials on new and revised regulations. It used the agency’s online media to provide information on new and revised export control legislation and related issues. As a result of the publication program, various existing publications explaining the export control regime were consolidated into a single publication, increasing the efficiency and satisfaction of outreach.
