Zaporizhzhia Nuclear Power Plant Briefly Loses External Power, Restored via 330 kV Line

Zaporizhzhia Nuclear Power Plant Briefly Loses External Power, Restored via 330 kV Line

The International Atomic Energy Agency (IAEA) reported on August 4 that the Zaporizhzhia Nuclear Power Plant briefly lost external power supply that day. This marked the 24th occurrence of external power interruption at the plant since the outbreak of the related conflict. According to the report, the plant lost connection with the Ferrosplavnaya-1 transmission line, currently the only one still in service, in the afternoon, and emergency diesel generators provided backup power thereafter. The IAEA stated that the cause of the incident remains unclear. The plant management said the brief external power interruption was related to a technical fault in the automatic control system, and power supply was restored in less than an hour. Currently, the plant's auxiliary power is supplied by the 330 kV Fer...

Krško Nuclear Power Plant Operates at Full Capacity; Low Sava River Water Level May Affect Unit Output

Krško Nuclear Power Plant Operates at Full Capacity; Low Sava River Water Level May Affect Unit Output

Slovenia's Krško Nuclear Power Plant continues to operate at full capacity, but due to low water levels and elevated water temperatures in the nearby Sava River, a reduction in reactor power cannot be ruled out in the future. The plant stated that it is utilizing its cooling tower system and operating in compliance with environmental restrictions related to the Sava River. Due to insufficient recent precipitation, the Sava River's water level remains low, and river water temperatures are also staying in a higher range. Plant management also noted that increased cooling demands have already had a certain impact on the unit's power generation efficiency. Krško Nuclear Power Plant has notified relevant authorities in Slovenia and Croatia that if environmental restrictions are further tightened, it may be necessary to...

Mitsubishi Heavy Industries to Fully Develop Small Modular Reactors, Targeting Commercialization in Japan

Mitsubishi Heavy Industries to Fully Develop Small Modular Reactors, Targeting Commercialization in Japan

Against the backdrop of the Japanese government's push to expand nuclear energy utilization, Mitsubishi Heavy Industries has decided to proceed with full-scale development of Small Modular Reactors (SMRs), with the goal of achieving commercial application in Japan. This is seen as a significant step forward by a Japanese private enterprise toward the practical deployment of SMRs. The Basic Energy Plan approved by Japan's Cabinet last year calls for maximizing the use of nuclear energy. At a ministerial meeting held last week, the Japanese government once again confirmed its commitment to advancing the research, development, and deployment of next-generation nuclear reactors. SMRs represent one of the technology pathways for next-generation nuclear reactors. Due to their smaller unit size and higher degree of modularization, the industry generally...

Cold Functional Test of Tianwan Nuclear Power Plant Unit 8 Successfully Completed

Cold Functional Test of Tianwan Nuclear Power Plant Unit 8 Successfully Completed

On August 3, the cold functional test (hereinafter referred to as the "cold test") of Tianwan Nuclear Power Plant Unit 8, constructed by China Nuclear Industry 23 Construction Co., Ltd. (CNI23), was successfully completed, marking the official transition of the unit from the engineering installation phase to the system commissioning and testing phase, laying a solid foundation for subsequent hot functional test, reactor fuel loading, and grid connection. The cold test is the first comprehensive commissioning test after a nuclear power unit enters the system commissioning phase and is one of the important milestone nodes in nuclear power plant engineering construction. Its main purpose is to verify the integrity and leak-tightness of the pressure boundary, including primary loop pipeline welds, equipment, and high-pressure sections of connected systems, comprehensively inspect on-site installation quality, and precisely identify potential hazards. It serves as the first comprehensive and systematic "physical examination" of the reactor before its operation.
