Korea Atomic Energy Research Institute

The Korea Atomic Energy Research Institute (KAERI) is South Korea’s national organization dedicated to the research and development of nuclear science and technology. Its core mission involves advancing peaceful uses of nuclear energy through the design and testing of reactor concepts, such as the SMART integral pressurized water reactor. KAERI conducts extensive studies on nuclear fuel cycles, including enrichment, reprocessing and waste management strategies. The institute also investigates radiation safety and the application of isotopic techniques in medicine, agriculture and industry. By providing technical support and expertise to governmental bodies and private sector partners, KAERI helps shape national nuclear policy and regulatory frameworks. International collaboration is a regular feature of its work, with joint projects and information exchanges involving research institutions and agencies worldwide.

Headquartered in South Korea, KAERI operates as a government‑funded research institute under the authority of the Ministry of Science and ICT. It maintains a network of specialized laboratories and test facilities that support its broad research agenda. Among its distinguishing attributes are deep expertise in nuclear fuel cycle technologies, advanced radiation safety protocols, and the development of isotopic applications for medical diagnostics and industrial processes. The institute also contributes to nuclear non‑proliferation efforts by improving safeguards measurement techniques and participating in international verification activities. In addition to its scientific work, KAERI provides training and education programs for engineers and scientists entering the nuclear sector. The 2021 cyber incident, in which North Korean threat actors exploited a VPN vulnerability to access thirteen internal IP addresses, highlighted the need for robust security measures protecting sensitive nuclear research data. Following the breach, KAERI acknowledged the intrusion, issued an apology for the initial denial, and patched the VPN flaw to prevent further unauthorized access. These actions underscore the institute’s commitment to both scientific excellence and the protection of its critical information assets.
