External power supply interruption at Zaporizhzhia Nuclear Power Plant has lasted for 14 days

External power supply interruption at Zaporizhzhia Nuclear Power Plant has lasted for 14 days

Yashina, head of communications at the Zaporizhzhia Nuclear Power Plant, stated that the external power supply interruption at the plant has lasted for 14 days, with power currently provided by diesel generators, and that on-site personnel are still able to ensure the safe condition of the plant. According to an earlier statement from the plant, on August 20, the "Ferroalloy-1" power line was damaged, causing the external power supply interruption at the Zaporizhzhia Nuclear Power Plant. The damage site is located in an area where repair work cannot currently be carried out. After the loss of external power, the plant activated its backup power system. Fuel reserves remain available on site, but to conserve these reserves and maintain stable equipment operation, the operating mode of the diesel generators needs to be optimized. Yashina stated that the plant has been powered by diesel generators for 14 consecutive days...

South Korea's Nuclear Safety Regulatory Budget for 2027 Rises to KRW 303 Billion

South Korea's Nuclear Safety Regulatory Budget for 2027 Rises to KRW 303 Billion

The Nuclear Safety and Security Commission (NSSC) of South Korea announced on September 1 that it has allocated KRW 303 billion for the 2027 budget, an increase of KRW 10.4 billion from this year. The new budget focuses on areas such as small modular reactor regulation, spent nuclear fuel safety, nuclear facility decommissioning review, environmental radiation monitoring, and nuclear safety information disclosure. Regarding small modular reactors, as non-light water reactor-type small modular reactor development projects aim to obtain licenses by the early 2030s, South Korea will invest KRW 8 billion in R&D to establish a new safety evaluation system. In addition, in line with the preliminary review system set to take effect in November this year, the government has allocated KRW 2.7 billion to conduct preliminary reviews of non-light water reactor-type small modular reactors expected to file applications next year. This system allows applicants to request regulatory review of reactor designs before formally submitting license applications.

Zaporizhzhia Nuclear Power Plant Relies on Emergency Diesel Generators to Maintain Operations

Zaporizhzhia Nuclear Power Plant Relies on Emergency Diesel Generators to Maintain Operations

The International Atomic Energy Agency (IAEA) recently stated that the Zaporizhzhia Nuclear Power Plant (ZNPP) has been relying on emergency diesel generators to maintain critical safety systems for over a week following the interruption of its external power supply. After inspections by the agency's on-site expert team, it was confirmed that as of the 23rd local time, the plant's diesel reserves could support approximately 10 days of operation, approaching the minimum regulatory requirement. According to the IAEA, the Zaporizhzhia Nuclear Power Plant lost its connection to the only remaining 330 kV Peresopravna-1 external transmission line starting on the 20th. Subsequently, the plant activated multiple emergency diesel generators to power critical equipment, including the six reactors and pumps related to spent fuel cooling and storage. The IAEA...

South Korean research team evaluates pipe rupture risk in nuclear power plants using probabilistic analysis

South Korean research team evaluates pipe rupture risk in nuclear power plants using probabilistic analysis

Researchers from Seoul National University of Science and Technology in South Korea have recently proposed a sensitivity analysis method based on probabilistic fracture mechanics to evaluate the rupture frequency of main coolant piping systems in nuclear power plants. This method can analyze the impact of uncertainties and modeling assumptions on prediction results, helping engineers distinguish extremely low-probability events from relatively more likely failure scenarios. In nuclear power plants, the main coolant piping system plays a critical role in maintaining structural integrity under normal reactor operating conditions. A pipe rupture could trigger a loss-of-coolant accident, and therefore this system has long been included in the key scope of nuclear power plant safety design and assessment.
