Unit 2 of the Czech Temelín Nuclear Power Plant shut down due to a control system fault

Unit 2 of the Temelín Nuclear Power Plant in the south of the Czech Republic has been taken out of service due to a fault in the control system of its non-nuclear portion. Marek Sviták, spokesperson for the Temelín Nuclear Power Plant, said that power engineers shut down Unit 2 of the Temelín Nuclear Power Plant that day because of a fault in the control system of the non-nuclear portion. After the necessary inspection and maintenance work is completed, the unit is expected to resume operation and return to power generation on Thursday of this week. At the same time, Unit 1 of the Temelín Nuclear Power Plant is currently operating normally at full power and has not been affected. In addition to the Temelín Nuclear Power Plant, the...

Czech Temelín Nuclear Power Plant to Load US Nuclear Fuel by Year-End

On September 9, the Temelín Nuclear Power Plant in the southern Czech Republic will begin using nuclear fuel produced by the US company Westinghouse Electric Company (Westinghouse). Czech energy company ČEZ has obtained permission from the Czech State Office for Nuclear Safety to use this type of fuel at the Temelín Nuclear Power Plant. The Temelín Nuclear Power Plant has two units in total. According to the plan, Westinghouse nuclear fuel will be loaded into the reactor core during the outage and maintenance of Unit 1 at the end of this year. The Dukovany Nuclear Power Plant, located in the southeastern Czech Republic, also plans to switch to Westinghouse fuel. Existing Czech nuclear power plants currently use Russian nuclear fuel, supplied by TVEL Fuel Company, a subsidiary of the Russian state nuclear energy corporation Rosatom...

Czech nuclear power plants largely unaffected by summer heat and drought

The Czech State Office for Nuclear Safety (SÚJB) stated on August 26 that this summer's heat waves and drought only caused a slight decline in electricity generation at the Temelín and Dukovany nuclear power plants, without leading to reactor power reduction or raising nuclear safety concerns. Currently, both plants meet the conditions for safe operation, including adequate cooling and water supply guarantees. SÚJB noted that some European nuclear power plants reduced output or temporarily shut down during high-temperature periods, mainly due to their cooling methods. Some plants use once-through cooling, making their operation directly affected by river water temperature and flow rate. When water temperatures rise and river flows are low, plants may reduce output due to environmental discharge limits...

Budapest Launches Feasibility Study for Long-Distance Heat Supply from Paks Nuclear Power Plant

On August 11, 2026, Budapest Public Services Company (BKM), in partnership with the Budapest University of Technology and Economics, launched a feasibility study to explore the delivery of thermal energy from the Paks Nuclear Power Plant to the city's district heating system via a hot-water pipeline of approximately 125 kilometers. The study focuses on the technical, economic, and construction feasibility of the project. The Paks Nuclear Power Plant is located about 100 kilometers from the capital, and the current heat load of Budapest's district heating system is approximately 100 MWth in summer, peaking at 1,000 MWth in winter. The core significance of this concept lies not only in providing a low-carbon heat source for the city but also in improving the efficiency of waste heat utilization at the nuclear power plant. The Paks Nuclear Power Plant currently...

Temelín Nuclear Power Plant in Czech Republic Records Second-Highest Monthly Generation in July

Despite prevailing high temperatures, the Czech Temelín Nuclear Power Plant achieved its second-highest monthly electricity generation this year. In July, the plant delivered 1,603,637 MWh of electricity to the transmission grid, nearly matching the May record of 1,617,093 MWh. This is sufficient to cover the electricity needs of all Czech households for more than one month. Thanks to its cooling tower system, the Temelín plant was unaffected by the hot and dry weather. In contrast, some nuclear power plants abroad were forced to reduce output or even shut down due to falling river levels and rising water temperatures. However, Temelín's closed cooling cycle and its cooling towers enable it to operate independently of direct water source suppl...
