French energy company Électricité de France (EDF) has been forced to temporarily shut down three nuclear reactors and reduce power at eight more as a result of the ongoing heatwave impacting Europe. The measure is an environmental protection requirement to avoid discharging too much hot water into rivers already warming from the heatwave. The shutdowns are the second time in recent that EDF has had to stop nuclear reactors due to the extreme heat of the record-breaking heatwave.
Électricité de France (EDF) announced that the Heysham 1 and Hartlepool nuclear power plants have extended their operations for an additional two years, generating electricity until 2030. The decision comes following a detailed review covering technical aspects like the condition of the boilers, graphite cores, as well as supply chain resilience and workforce planning. EDF manages the United Kingdom’s five operational nuclear power plant sites and is also building the new Hinkley Point C plant.
France’s nuclear safety regulatory (ASNR) has published its opinion on the safety features proposed by Newcleo for its planned mixed-oxide fuel facility, concluding that the provisions adopted by the company for its safety approach are satisfactory at this stage. Newcleo submitted its Safety Options File to the ASNR for its facility in 2024, and the ASNR’s opinion will contribute to securing the authorization application to construct such a facility. Newcleo also announced it is entering a new phase of collaboration with French authorities following the evaluation of its application for Phase 2 of the France 2030 innovative nuclear reactor program.
French molten salt reactor developer Stellaria signed a memorandum of understanding with Unitel Group and Energie Hub to develop an integrated low-carbon energy hub in the Fos-sur-Mer industrial region of southern France. The project proposes the phased deployment of multiple Stellarium molten salt reactors to supply electricity, industrial heat, grid support services, and energy storage for one of Europe's largest industrial areas. The partners also plan to develop an AI-powered energy management platform to optimize power production, consumption, and grid operations while establishing a dedicated entity to finance and operate the project.
Great British Energy - Nuclear (GBE-N) has selected U.S. engineering group Jacobs to provide planning and consenting services for the planned small modular reactor (SMR) projects in the United Kingdom. Jacobs will provide strategic planning, consent support, and leadership to key land-use planning activities to help advance required project approvals. The initial focus will be on new nuclear development at the Gwyndod and Oldbury-on-Severn sites, as well as the potential to include additional sites.
Czech nuclear utility CEZ started the process to extend the two units at the Temelín Nuclear Power Plant to 80 years, so Temelín 1 and 2 will operate until 2080 and 2082 respectively. Significant investment and modernization work will be required to enable the extended operation of the two units, including modernization of the control and management systems and construction of a new hall for the maintenance of large technological units. The Czech Republic has two nuclear power plants and has plans to build new traditional and small modular reactor units in the future.
The Czech Ministry of Industry and Trade, ČEZ, and Rolls-Royce SMR signed a memorandum of understanding to begin preparatory work for small modular reactor projects at two additional sites: Tušimice and Dětmarovice. The agreement expands the Czech Republic's SMR deployment strategy beyond the first planned project at the Temelín nuclear power plant and supports the country's goal of developing up to 3 GW of SMR capacity. Preparatory activities will include site assessments, permitting, licensing, and infrastructure planning to determine the suitability of both locations for future reactors.
German authorities approved an application allowing Framatome's fuel fabrication facility to produce nuclear fuel assemblies under a licensing agreement with Russia's Rosatom and its subsidiary TVEL, despite political concerns surrounding the cooperation. Officials said the approval was required under existing German nuclear law, while emphasizing that broader restrictions on such partnerships would need to come through European Union sanctions rather than national licensing decisions. The authorization includes strict security conditions, including prohibiting Rosatom personnel from accessing the site and requiring independent security audits.
Slovakia's Mochovce Unit 4 completed reactor assembly and hermetic sealing, marking a major milestone as it enters the final stages of commissioning before startup. Following the successful loading of 349 fuel assemblies, the plant will undergo strength, leak, and pre-criticality tests before achieving its first controlled nuclear fission reaction. Operators expect the unit to begin supplying electricity to the grid by the end of summer 2026, with power output increasing gradually through a series of regulatory tests. Once fully operational, the reactor will further increase Slovakia's reliance on nuclear energy, which is expected to provide more than three-quarters of the country's electricity.
Bulgaria and the United States reaffirmed their commitment to constructing Units 7 and 8 at the Kozloduy Nuclear Power Plant, describing the AP1000 project as a strategic priority in bilateral cooperation. During high-level discussions, officials reviewed progress on engineering work, upcoming project milestones, and potential financing from U.S. export credit institutions to support construction. The two sides also pledged to maintain close cooperation throughout the project's implementation as Bulgaria advances its plans to expand nuclear generating capacity.
Serbian Energy Minister Dubravka Ðedović has outlined the studies required for the country to follow the recommended IAEA milestones approach to introducing nuclear power in Serbia. According to Handanovic, there is a need for at least 18 more studies to cover topics such as regulatory and legislative frameworks, environmental protection, and nuclear supply chains. Serbia’s government plans to decide on implementing a nuclear power program in 2027 after presenting the Preliminary Technical Study on the Peaceful Use of Nuclear Energy in March of this year.
The Belgian government announced nearly €11 million ($12.54 million) in funding for nuclear research in the country’s latest step to maintain its nuclear power sector. The funding will go to eight innovative nuclear power projects that have been proposed by Belgian universities, research centers, and other companies. Several of these projects will focus on small modular reactors (SMR). Belgium previously passed an exit law to phase out nuclear power gradually by 2025, but the current government recently scrapped this law in order to bolster the country’s energy sector.
Spain’s Nuclear Safety Council (CSN) has issued a favorable report on the renewal of the operating license for the two-unit Almaraz Nuclear Power Plant, stating that the plant meets the conditions to operate safely until June 2030. In 2020, the CSN approved the operation of Almarez until 2030, but decided to extend operations until only 2027 for unit 1 and 2028 for unit 2. Spain is currently in the process of phasing out its remaining nuclear power units, with the current plan to shut down all of its nuclear reactors by 2035.
Ukraine’s cabinet of ministers has agreed to loan $12.4 million to the country’s Eastern Mining and Processing Plant to increase uranium ore extraction and uranium oxide concentrate production. The facility plans for a gradual increase in uranium oxide concentrate to 45 tons per month, construction of new mining levels, and design and construction of a new sulphuric acid production plant. In 2022, Ukraine’s energy ministry announced the country aims to become self-sufficient in uranium by 2027.
The European Investment Bank has approved a loan of €800 million ($914 million) for the refurbishment of Romania’s Cernavoda Nuclear Power Plant unit 1 as part of the bank’s €3.7 billion package of measures for European energy projects.
