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...

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...

Zaporizhzhia Nuclear Power Plant Loses External Power for Six Days

On August 25 local time, the Zaporizhzhia Nuclear Power Plant (ZNPP) stated that it had lost external power since August 20 and had been relying on backup diesel generators to meet on-site electricity demand for six consecutive days. The plant's existing fuel reserves can still ensure operation, but difficulties in fuel resupply have not yet significantly eased. Yevgeniya Yashina, head of communications at ZNPP, stated that plant staff are monitoring nuclear safety parameters and the operation of backup diesel generator units around the clock. She noted that fuel transportation still faces difficulties due to shelling on roads leading to the plant; to improve the efficiency of existing reserve utilization, the plant has optimized the operation of diesel generators...

Repeated Power Outages at Zaporizhzhia Nuclear Power Plant Raise Concerns over Equipment Aging and Safety Risks

August 13 news, the issue of repeated interruptions to the external power supply at the Zaporizhzhia Nuclear Power Plant continues to draw attention. Relevant data shows that since February 2022, the plant has experienced 26 power outages, 14 of which occurred in the first 8 months of 2026. The Zaporizhzhia Nuclear Power Plant is the largest nuclear power plant in Europe. Once the external power supply is interrupted, the plant must switch to backup power to maintain the operation of essential safety systems. Frequent switching of power supply modes not only increases operational pressure but also poses additional risks to nuclear safety and radiation safety. Relevant parties have stated that signs of equipment aging at the Zaporizhzhia Nuclear Power Plant are intensifying, with the condition of diesel generator sets being particularly concerning. The backup diesel generator sets are generally...

Zaporizhzhia Nuclear Power Plant to Raise Spent Fuel Pool Water Levels to Mitigate Power Outage Risks

The International Atomic Energy Agency (IAEA) stated that the operator of the Zaporizhzhia Nuclear Power Plant has decided to raise the water levels in the spent fuel pools on site to enhance safety buffer capacity in the event of a prolonged loss of external power. The primary purpose of raising the water levels is to extend the time before water in the spent fuel pools begins to boil and evaporate under extreme conditions where external power to the plant is interrupted for an extended period, diesel reserves are depleted, and emergency diesel generators can no longer supply power to the cooling systems. Spent fuel pools are used to store used nuclear fuel underwater, typically for at least five years, allowing its radioactivity and residual heat to gradually decay, making continuous cooling a critical element of nuclear safety. All six units at the Zaporizhzhia Nuclear Power Plant...
