en.Wedoany.com Reported - On the 16th, the Nuclear Safety and Security Commission visited the Wolseong Nuclear Power Plant in Gyeongju, North Gyeongsang Province, to observe physical protection drills at the plant and inspect drone detection and response equipment as well as protective facilities. Physical protection refers to the security system of personnel, equipment, and procedures established to protect major facilities such as nuclear power plants from external intrusion or attack.

Currently, domestic nuclear power plants in South Korea operate radio frequency scanners for detecting drones and jammers that interfere with drone flight. Radio frequency scanners identify the location and direction of drones by tracking communication signals between the drone and its remote controller. Jammers disrupt drone control signals, making it difficult for them to fly or return to their original positions.

During this drill at the Wolseong Nuclear Power Plant, radar equipment was also put into trial operation for the first time at a domestic nuclear power plant. Radar identifies information such as distance, speed, and direction by emitting radio waves and analyzing the signals reflected from objects. As radar can detect autonomous drones that fly along preset paths without communicating with a remote controller, it can compensate for the limitations of existing radio frequency scanners.

The Nuclear Safety and Security Commission confirmed the procedures for security personnel to detect and identify illegal drones using radar, as well as whether the subsequent response system was appropriate.

The radar introduced at the Wolseong Nuclear Power Plant will be officially put into operation at the end of June after additional performance testing and operator training. The Nuclear Safety and Security Commission plans to study the possibility of expanding its deployment to other nuclear power plants after comprehensively evaluating the operational results.

Jo Jeong-ah, Director of the Office of Affairs at the Nuclear Safety and Security Commission, stated: "We expect that the introduction of radar at the Wolseong Nuclear Power Plant will improve the detection performance of illegal drones around the plant. We will continue to ensure that nuclear power operators expand their detection and response equipment and enhance their response capabilities through drills."
