North Gyeongsang Provincial Council Establishes Special Committee on Nuclear Power

On August 25, the North Gyeongsang Provincial Council in South Korea established a Special Committee on Nuclear Power on the first day of its 365th special session, electing provincial council member Kim Jae-jun as committee chairman and Lee Dong-hyeop as vice chairman. According to reports, the committee will focus on addressing major nuclear power-related issues in the region, while also working to enhance the competitiveness of the nuclear power industry in North Gyeongsang Province and safeguard the safety and rights of provincial residents. North Gyeongsang Province is one of the regions in South Korea with a relatively high concentration of nuclear power facilities, having already developed a certain base of nuclear institutions and industrial infrastructure. With the recent confirmation of two new nuclear reactor projects in Yeongdeok County, the committee plans to strengthen on-site investigations and legislative activities to promote the nuclear power industry as a new growth driver for the region's underdeveloped areas.

South Korea's Wolsong Nuclear Power Plant Units 2, 3, and 4 Pressure Tube Procurement Pushed for Preliminary Feasibility Study Exemption, Sparking Controversy

The lifetime extension issue for South Korea's Wolsong Nuclear Power Plant Units 2, 3, and 4 has not yet been finalized, yet the procurement of pressure tubes—the core equipment—is being pushed to be excluded from the preliminary feasibility study, triggering a direct confrontation between industry circles and environmental groups. The Korea Hydro & Nuclear Power labor union recently submitted a proposal to Democratic Party lawmaker Song Young-gil, requesting that the government grant a preliminary feasibility study exemption for the relevant procurement and initiate ordering at the earliest opportunity. Song subsequently forwarded the opinion to the Office for Government Policy Coordination. It is understood that the government is internally considering submitting the matter as an exemption case for deliberation at the September State Council meeting. Supporters argue that Wolsong Units 2, 3, and 4 are pressurized heavy water reactors, and pressure tubes are critical equipment determining unit operation, from order placement...

Sea Temperature Approaching Shutdown Threshold, Nuclear Power Belt on South Korea's East Coast Faces Load Reduction Pressure

Climate change is pushing nuclear power plants on South Korea's east coast toward new operational boundaries. South Korean nuclear plants generally rely on seawater as cooling water; after the heat generated by the reactor drives the turbine, seawater is needed to condense the steam back into water. Once the intake water temperature approaches or exceeds the design seawater temperature set by the equipment, heat exchange efficiency declines, affecting the heat dissipation capacity of key safety systems, and the plant must reduce load or even shut down in accordance with safety regulations. The area currently at greatest risk is around Uljin in North Gyeongsang Province. Data from the National Institute of Fisheries Science shows that nearshore surface seawater temperatures along parts of the east coast have approached 30°C, with multiple observation points near Uljin recording approximately 29.6°C to 30.2°C on the afternoon of August 7.

South Korea Accelerates Safety Reviews of Long-Term Operating Nuclear Reactors and Advances Licensing of First Spent Fuel Dry Storage Facility

The Nuclear Safety and Security Commission (NSSC) of South Korea stated at its second-half work report meeting on August 4 that it will accelerate safety reviews of long-term operating nuclear reactors while simultaneously advancing regulatory efforts such as licensing systems for spent fuel dry storage facilities and small modular reactors. Under the plan, the NSSC will conduct safety inspections on nine reactors applying for continued operation, with review standards referencing newly built nuclear power plants and confirming safety margins in consideration of the characteristics of long-term unit operation. Among these, whether Kori Nuclear Power Plant Units 3 and 4 will be approved for continued operation in the second half of this year, and whether Hanbit Nuclear Power Plant Units 1 and 2 will be approved for continued operation in the first half of next year, are the near-term review priorities...

South Korea Confirms Operating Nuclear Power Units Unaffected by Strong Earthquake in Kyushu, Japan

Following the strong earthquake in the Kyushu region of Japan, related aftershock signals have been detected in southern South Korea. The Nuclear Safety and Security Commission (NSSC) of South Korea stated that inspections confirmed all operating nuclear power units within the country remain unaffected. The NSSC noted that after the earthquake, inspections were conducted on all 27 operating nuclear power units, including the Kori Nuclear Power Plant in Busan and the Wolseong Nuclear Power Plant in Gyeongju, with no significant abnormalities or safety issues found. Korea Hydro & Nuclear Power (KHNP) also stated that no reports of damage to nuclear facilities have been received so far. The NSSC will continue to monitor the operational status of nuclear power plants to respond to potential subsequent aftershocks....

Heavy water leak at Wolseong Nuclear Power Plant Unit 2 in South Korea found to be far larger than initially reported

The actual scale of the heavy water leak that occurred at Wolseong Nuclear Power Plant Unit 2 in Gyeongju, North Gyeongsang Province, South Korea, in September last year, is reported to be far larger than the initially disclosed figure. The Gyeongju Environmental Movement Alliance disclosed on the 30th that a detailed internal report obtained from Korea Hydro & Nuclear Power (KHNP) shows the total amount of heavy water leaked was 1,311.15 kg, approximately five times the initially reported 256 kg, of which 5.14 kg was recorded as having leaked outdoors. After the incident, Korea Electric Power Corporation (KEPCO) had reported a heavy water leak of 256 kg and stated that no external leakage occurred. The detailed report now made public reveals...
