In the late 80s, non-proliferation of weapons of mass destruction, including nuclear, chemical, and biological, became an internationally important issue, and in order to keep pace with the international situation, Korea amended the Foreign Trade Act in 1992 to legislate the export control of strategic goods. In addition, Korea joined the NSG, one of the international export control regimes, in 1995, and nuclear power operators are required to obtain export licenses in accordance with the NSG export control guidelines. In the nuclear export business, technical documents, equipment, materials, SW, etc. are exported to the importer, and the export items may include strategic items designated by the NSG, so operators must check whether they are strategic items and, if so, obtain an export license in accordance with foreign trade laws that reflect the NSG export control guidelines. In the case of processing and exporting goods or materials imported from another country, exporters must fulfill complex nuclear export control procedures, including obtaining the original supplier’s consent for re-transfer. In recent years, the international situation on export control has been more sensitive than ever, including the Russo-Ukrainian war, the U.S.-China semiconductor supremacy dispute, and U.S. lawsuits against domestic companies related to original technologies. In the worst-case scenario, a company may not be able to fulfill a contract due to export control issues. In order to facilitate the smooth export business of operators when exporting nuclear energy, ‘Nuclear Export Control Pre-Consulting’ is proposed to check compliance with export control requirements in advance and provide operators with customized export control implementation plans reflecting business characteristics. Through the pre-consultation, issues, requirements, and preparatory documents related to nuclear export control can be checked before the export business starts in earnest, i.e., when the decision to participate in the business is made, and the business can be supported to export smoothly by complying with the export control system. The most important aspect of pre-consultation is that domestic nuclear exporters need to know and apply for the program. To this end, the program will be actively promoted online and offline, and support will be provided for easy application through NEPS. In addition, procedures and outcomes will be continuously refined to ensure that the program is a means of ensuring full compliance with international nuclear non-proliferation norms for nuclear exports.
