Cernavoda Nuclear Power Plant Fully Shut Down Due to Falling Danube River Water Levels

Due to the continuous decline of the Danube River water level, the two units of Romania's only nuclear power plant, the Cernavoda Nuclear Power Plant, have been successively shut down. To alleviate the pressure on electricity supply, Unit 4 of the Rovinari coal-fired cogeneration plant has been put into operation, adding approximately 330 megawatts of generating capacity to Romania's power system. Romania's nuclear power company (Nuclearelectrica) previously reported that due to the sharp decline in the Danube River water level, which affected the assurance of cooling water for the reactor, Unit 2 of the Cernavoda Nuclear Power Plant was shut down in a controlled manner on the morning of August 13. The company stated that the shutdown process was carried out in accordance with procedures. At the end of July this year, Unit 1 of the Cernavoda Nuclear Power Plant had already been shut down for the same reason...

Bulgaria's Kozloduy NPP Addresses Challenges of Low Danube River Water Levels

Bulgaria's Ministry of Energy stated on August 16 that the Kozloduy NPP is currently operating as planned. In response to the persistently rare low water levels in the Danube River, the plant has further studied and implemented preventive arrangements based on existing technical and organizational measures to ensure stable unit operation under complex hydrological conditions. The Bulgarian Ministry of Energy stated that the Kozloduy NPP has established a dedicated working group to evaluate various options for ensuring the plant's normal operation, with a focus on facilities related to the riverbank pumping station. The working group is continuously optimizing the riverbank pumps, reactor unit cooling systems, spent fuel storage facilities, and the overall water...

Unit 2 of Romania's Cernavodă Nuclear Power Plant shut down for at least 10 days due to falling Danube River water levels

Romeo Urjan, head of Romania's Cernavodă Nuclear Power Plant, said that due to the continuous decline of Danube River water levels, Unit 2 of the plant has been shut down since August 13 for at least 10 days. Romania's Ministry of Energy stated on August 12 that Unit 2 of the Cernavodă Nuclear Power Plant required a temporary shutdown. As planned, the shutdown operation began on the morning of August 13 and was completed before noon that day. Urjan stated that Danube River water levels are expected to continue declining over the next 10 days, so the plant currently has no plans to restart Unit 2. He emphasized that this shutdown is unrelated to nuclear safety issues or emergencies, with the main reason being...

Romania's Cernavoda Nuclear Power Plant to Shut Down Due to Falling Danube River Levels

Romania's Ministry of Energy announced on the 12th local time that, due to current hydrological conditions, Unit 2 of the Cernavoda Nuclear Power Plant will undergo a controlled shutdown starting on the 13th. Cernavoda is Romania's only nuclear power plant, and this shutdown will mark the first time the plant has been completely taken offline since 2003. The Cernavoda plant has two units, with Unit 1 already shut down at the end of last month. The plant accounts for approximately one-fifth of Romania's electricity generation. Romanian authorities had previously taken engineering measures to delay the shutdown of Unit 2, including dredging relevant sections of the Danube River, blasting and removing underwater rock obstacles, clearing the riverbed, and sinking barges loaded with crushed stone into the river channel to adjust water flow conditions. These operations involved an investment of over 2 million euros.

Danube River water levels continue to drop, Romania's only nuclear power plant to shut down completely

Affected by prolonged drought and high temperatures, the water level of the Danube River has been continuously declining, impacting the operation of multiple nuclear power plants along its banks. Romanian authorities have confirmed that both units of the country's only nuclear power plant, the Cernavodă Nuclear Power Plant, will be completely shut down to prevent damage to the cooling system. Romania's Acting Prime Minister Ilie Bolojan has called on residents and large industrial users to voluntarily reduce electricity consumption, especially by controlling the load between 8:00 PM and 11:00 PM. He stated that Romania often faces electricity shortage pressure during this period. Bolojan noted that the Danube River flow rate during the same period in previous years was typically 3,900 to 4,500 cubic meters per second, but it has now dropped to 1,600 cubic meters per second, and is expected to continue decreasing in the coming days.
