Boric Acid Leakage During Spent Fuel Transfer Preparation at South Korea's Hanul Nuclear Power Plant

Hanul Nuclear Power Plant in Uljin County, North Gyeongsang Province, South Korea, recently disclosed that at 10:16 a.m. on the 3rd, a boric acid solution leakage incident occurred in the auxiliary building of Unit 2 at Shin Hanul Nuclear Power Plant. The incident happened while workers were preparing to transfer spent fuel from a transport container in the spent fuel loading pool to the spent fuel storage pool, and the preliminary cause has been attributed to improper on-site operations. Boric acid solution is used in spent fuel storage-related operations. As the solution is associated with the spent fuel storage environment, it carries radioactive management attributes. Hanul Nuclear Power Plant stated that leakage containment measures were immediately taken after the leak occurred, and the leaked material was collected in the decontamination area and recovered to the controlled area...

KEPCO KPS Q2 Results Miss Expectations; Nuclear Maintenance Demand Expected to Drive Recovery in H2

KEPCO KPS's Q2 results significantly missed market expectations, mainly due to factors such as extended long-term planned preventive maintenance cycles for nuclear power plants and a reduction in external and overseas variable works. Data shows that the company's preliminary Q2 sales stood at KRW 437.9 billion, down 3.5% year-on-year; operating profit was KRW 43.6 billion, down 33.6% year-on-year, approximately 30.1% below market consensus; net profit attributable to controlling shareholders was KRW 38.3 billion, down 24.8% year-on-year. The operating margin fell to 10.0%, down 4.5 percentage points from the same period last year, indicating pressure on both the revenue side and, to some extent, the cost side. The nuclear maintenance business was one of the key factors dragging down Q2 performance. In Q2...

Korea's Nuclear Safety and Security Commission Conducts Safety Inspection at Hanul Nuclear Power Plant

Amid the ongoing heatwave, Korea's Nuclear Safety and Security Commission is closely monitoring safety inspections at domestic nuclear power plants. On August 6, Commission Chairman Choi Won-ho visited the Hanul Nuclear Power Plant in Uljin, North Gyeongsang Province, for an on-site inspection. The primary purpose of this inspection was to verify whether the plant's safety systems can operate properly under continuously rising seawater temperatures. As rising seawater temperature is a factor that directly affects the cooling system, the Hanul plant conducted detailed checks on heat exchanger performance and thermometer conditions. Chairman Choi also held prior discussions via video conference with relevant nuclear agencies on response measures to high temperatures. During the subsequent on-site inspection, he reviewed...
