Emil Jacobs - Collectifission<p>"French nuclear fuel cycle company Framatome has been selected by Swiss operator Kernkraftwerk Gösgen-Däniken (KKG) to be the long-term supplier of nuclear fuel assemblies and related services for its Gösgen nuclear power plant, a statement said.</p><p>Framatome said the contract, the financial details of which were not disclosed, will see Framatome deliver fuel for reloads and provide reactor core fuel management services starting from 2026.</p><p>The agreement extends a decades-long relationship between Framatome and KKG, the company said. Framatome will supply its high thermal performance (HTP) fuel assemblies.</p><p>Gösgen, in the canton of Solothurn, northern Switzerland, is a 1,010-MW pressurised water reactor which began commercial operation in 1979.</p><p>Switzerland has four nuclear reactors in commercial operation at three sites: Beznau-1, Beznau-2, Gösgen and Leibstadt. Nuclear power provides about a third of Swiss power generation.</p><p>Last month, Framatome signed a contract to modernise the instrumentation and control systems at the Leibstadt nuclear power station.</p><p>At the end of 2024, Framatome announced it had loaded novel accident tolerant fuel for a fifth cycle of experimental operation at Gösgen."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Switzerland" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Switzerland</span></a> <a href="https://greennuclear.online/tags/France" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>France</span></a></p><p><a href="https://www.nucnet.org/news/framatome-gets-long-term-fuel-supply-contract-for-switzerland-s-goesgen-nuclear-plant-4-4-2025" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nucnet.org/news/framatome-gets</span><span class="invisible">-long-term-fuel-supply-contract-for-switzerland-s-goesgen-nuclear-plant-4-4-2025</span></a></p>
Emil Jacobs - Collectifission<p>"US microreactor technology company NANO Nuclear Energy Inc has signed a strategic collaboration agreement with the University of Illinois Urbana-Champaign to construct the first research KRONOS micro modular reactor on the university's campus.</p><p>The agreement formally establishes the University of Illinois Urbana-Champaign as a partner in the licensing, siting, public engagement, and research operation of the KRONOS MMR, while also identifying the university campus as the permanent site for the reactor as a research and demonstration installation.</p><p>The university plans to re-power partially its coal-fired Abbott power station with the KRONOS MMR, providing a zero-carbon demonstration of district heat and power to campus buildings as part of its green campus initiative. The project team aims to demonstrate how microreactor systems integrate with existing fossil fuel infrastructure to accelerate the decarbonisation of existing power-generation facilities.</p><p>Following initial arrangements, NANO Nuclear will begin the process of geological characterisation, including subsurface investigations, to support preparation of a Construction Permit Application (CPA) for submission to the US Nuclear Regulatory Commission (NRC). The company said this preparatory work is essential to understanding the environmental parameters of the site, including critical inputs to safety analysis, to ensure the utmost reliability and safety of the facility, and support NANO Nuclear's Preliminary Safety Analysis Report (PSAR) and Environmental Report (ER).</p><p>As part of the agreement, the University of Illinois Urbana-Champaign will lead the regulatory engagement with the NRC as well as public engagement, support licensing activities including the PSAR and ER, and play a key role in site layout, constructability assessment, and future operator training programmes. NANO Nuclear will oversee plant design, construction, system integration, and commercial pathway development.</p><p>"This milestone marks the beginning of site-specific development for NANO Nuclear's advanced KRONOS MMR technology and represents a defining moment in NANO Nuclear's path to commercialisation of the KRONOS MMR Energy System," the company said.</p><p>"This is the milestone we've been working so diligently towards, transforming design into reality," said NANO Nuclear Founder and Chairman Jay Yu. "With a site now selected and a world-class university as our partner, we are positioned to be among the first companies to deliver advanced reactor systems within the United States. This isn't just a research reactor, it's a proving ground for the future of safe, portable, and resilient nuclear energy. Moreover, this agreement will serve as a foundation for our long-term reactor strategy. Every milestone from this point forward brings us closer to delivering the next generation of nuclear energy to communities, campuses, and industries across the world."</p><p>"The KRONOS MMR project can not only be a national first, it can be a first for academia, enabling students, researchers, regulators, and the public to learn directly from a real-world microreactor development effort," added Illinois Caleb Brooks, Principal Investigator for the University of Illinois. "This system can be the most advanced nuclear research platform on any US campus, with the potential to enable a new paradigm of nuclear power through education, research, and at scale demonstration."</p><p>NANO Nuclear acquired the Micro Modular Reactor Energy System technology through its USD85 million acquisition of Ultra Safe Nuclear Corporation's (USNC's) nuclear technology, which was completed in January. At that time, NANO Nuclear renamed the technology as the KRONOS MMR.</p><p>The MMR is a 45 MW thermal, 15 MW electrical high-temperature gas-cooled reactor, using TRISO fuel in prismatic graphite blocks and has a sealed transportable core.</p><p>USNC had been working on deployment projects at Canadian Nuclear Laboratories' Chalk River site in Ontario, Canada, and at the University of Illinois Urbana-Champaign in the USA. The university informed the US NRC in June 2021 that it intends to construct an MMR on its campus, with the submission of the Letter of Intent being the first step in the NRC's two-step process to license the new research and test reactor facility. At the time of its purchase of USNC, NANO said it planned to extend the existing collaboration with the University of Illinois at Urbana-Champaign, while continuing the licensing process for the reactor with the NRC."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/US" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>US</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/agreement-to-build-microreactor-on-us-university-site" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/agreement-to-build-microreactor-on-us-university-site</span></a></p>
Emil Jacobs - Collectifission<p>"Polskie Elektrownie Jądrowe and the Westinghouse-Bechtel Consortium have agreed the terms and conditions of an Engineering Development Agreement for Poland's first nuclear power plant after a previous agreement expired.</p><p>In November 2022, the then Polish government selected Westinghouse AP1000 reactor technology for construction at the Lubiatowo-Kopalino site in the Choczewo municipality in Pomerania in northern Poland. In September 2023, Westinghouse, Bechtel and Polskie Elektrownie Jądrowe (PEJ) - a special-purpose vehicle 100% owned by Poland's State Treasury - signed an 18-month engineering services contract under which Westinghouse and Bechtel will finalise a site-specific design for a plant featuring three AP1000 reactors.</p><p>However, that contract expired at the end of March without a new agreement being concluded.</p><p>PEJ has now announced that an Engineering Development Agreement (EDA) - the so-called 'bridge agreement' - has been signed, establishing the framework for cooperation between PEJ and the Westinghouse-Bechtel Consortium for the upcoming months.</p><p>"The EDA opens the next stage in the construction of Poland's first nuclear power plant and enables continuation of project work, which will facilitate obtaining the necessary administrative decisions, licences and permits, etc, and initiate a further phase of in-depth geological surveys at the project site," it said.</p><p>PEJ added: "The agreement reached and the compromise worked out provide a solid and sustainable foundation for the continuation of partnership under the project. The Engineering Development Agreement will be signed after completing the governance process. Hence, the planned project work to inform the documents for Poland's first nuclear power plant required by applicable laws continue according to the adopted schedule."</p><p>"Today we are one step further in implementing the project of building the first Polish nuclear power plant," said Wojciech Wrochna, Government Plenipotentiary for Strategic Energy Infrastructure, Secretary of State in the Ministry of Industry. "The completion of negotiations between Polskie Elektrownie Jądrowe and the consortium of Westinghouse and Bechtel is a confirmation of our common determination to implement this undertaking.</p><p>"The signing of the so-called bridge agreement opens the next stage of our cooperation, which will allow for the effective implementation of the design process and then the construction of this facility, which is key to energy security."</p><p>Polish Prime Minister Donald Tusk said: "Negotiations on the bridge agreement with contractors have been completed and I would like to thank Minister Marzena Czarnecka and the team that worked on a better form of agreement. The first piece of good news: we are continuing the construction of the nuclear power plant. The second piece of good news: we have reached an agreement with our American partners in such a way that this agreement is much better from our point of view.</p><p>In late March, President Andrzej Duda signed a bill that designates funds from the national budget for the construction of Poland's first nuclear power plant. Under the bill, PEJ is set to receive PLN60.2 billion (USD15.5 billion) in public funding between 2025 and 2030. The remaining funding will be obtained from financial institutions, primarily foreign institutions supporting exports originating from equipment suppliers' countries, including export credit agencies, in particular the American export credit agency Export-Import Bank of the United States.</p><p>The aim is for Poland's first AP1000 reactor to enter commercial operation in 2033."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Poland" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Poland</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/new-agreement-enables-continued-development-of-polish-plant" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/new-agreement-enables-continued-development-of-polish-plant</span></a></p>
Emil Jacobs - Collectifission<p>"Estonia's Fermi Energia and South Korea's Samsung C&amp;T Corporation Engineering &amp; Construction Group have signed a teaming agreement to collaborate on the deployment of two BWRX-300 small modular reactors in Estonia.</p><p>Under the teaming agreement - signed in Seoul on 1 April - the cooperation between Fermi Energia and Samsung C&amp;T will focus on key aspects of the project, including the formation of an Engineering, Procurement, and Construction (EPC) partnership, site constructability review, cost estimation, and financing strategies. The agreement also positions Samsung C&amp;T as a potential EPC Prime Contractor and key commercial partner in the Estonian small modular reactor (SMR) project.</p><p>This collaboration builds upon a memorandum of understanding signed between the two companies in November 2024.</p><p>As part of the agreement, Fermi Energia and Samsung C&amp;T will work together during the pre-Front-End Engineering Design (Pre-FEED) phase to establish project terms and budget estimates. The Teaming Agreement also outlines plans for a full FEED phase, setting the stage for the regulatory approval and construction process.</p><p>The two companies plan to begin full-scale business procedures as early as the second half of this year, and the project aims to be commercially operated in 2035.</p><p>"The cooperation extends beyond Estonia, as both parties recognise the broader potential of SMR deployment across Northern Europe," Fermi Energia said. "Through this partnership, Samsung C&amp;T aims to play a key role in at least 10–15 BWRX-300 reactor projects across the region, leveraging economies of scale and minimising project risks."</p><p>"We will strengthen our position as a global SMR player along with the successful promotion of Estonia's first SMR project," said Kim Jeong-eun, head of the nuclear power plant sales team at Samsung C&amp;T.</p><p>"The signing of this teaming agreement reflects our commitment to preparing for a cost-effective and timely deployment of SMRs in Estonia," said Fermi Energia CEO Kalev Kallemets. "Nuclear energy is not a simple technology, and for a country of Estonia's size, it can only be implemented in cooperation with reliable, democratic partners. South Korea is already an important partner for Estonia in defence equipment manufacturing, and Samsung C&amp;T's experience in nuclear energy and large-scale power construction will be essential for ensuring SMR deployment in Estonia and Northern Europe stays on schedule and within budget."</p><p>Fermi Energia was founded by Estonian energy and nuclear energy professionals to develop deployment of SMRs in Estonia. In July 2019, the company launched a feasibility study on the suitability of SMRs for Estonia's electricity supply and climate goals beyond 2030, following a financing round from investors and shareholders.</p><p>In February 2023, the company selected GE Hitachi Nuclear Energy's BWRX-300 SMR for potential deployment by the early 2030s. GEH's BWRX-300 design is a 300 MWe water-cooled, natural circulation SMR with passive safety systems that leverages the design and licensing basis of GEH's ESBWR boiling water reactor.</p><p>In January this year, Fermi Energia submitted an application to Estonia's Ministry of Economic Affairs and Communications to begin the state spatial planning process for a 600 MW nuclear power plant. The municipal councils of Viru-Nigula and Lüganuse have formally agreed to participate in the spatial planning process, with decisions made in September 2023 and March 2024, respectively.</p><p>Fermi Energia expects to submit a construction permit application for the proposed plant in 2029, with construction targeted to begin in 2031. The first of two SMRs is set to be operational by the second half of 2035.</p><p>The Estonian parliament - the Riigikogu - passed a resolution in June last year supporting the adoption of nuclear energy in the country, paving the way for the creation of the necessary legal and regulatory framework. The parliament based its decision on analysis conducted by the Nuclear Energy Working Group, which concluded that the adoption of nuclear energy in Estonia was feasible."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Estonia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Estonia</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/teaming-agreement-signed-for-estonian-smr-project" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/teaming-agreement-signed-for-estonian-smr-project</span></a></p>
Emil Jacobs - Collectifission<p>"Brazil's National Nuclear Energy Commission has given an extendable 40-year authorisation for the operation of the Complementary Dry Storage Unit for Spent Fuel at the Angra nuclear power plant site.</p><p>Eletronuclear said the facility, which received its initial operation authorisation in 2021, was designed to accommodate up to 72 of the Holtec Hi-Storm FW dry storage casks, with the capacity to receive fuel until 2045.</p><p>In its announcement in the Official Gazette, the National Nuclear Energy Commission (CNEN) said assessments had shown there was "sufficient guarantee that the operation ... can be conducted without undue risk to the safety of workers, the public and the environment with regard to the areas of nuclear technical safety, radiological protection and physical protection of facilities and materials".</p><p>Eletronuclear said that it welcomed the authorisation as it does not see used fuel as radioactive waste because of the potential to resuse it in the future.</p><p>CEO Raul Lycurgo said: "This is an important milestone for Eletronuclear and the Brazilian nuclear sector. It confirms that, with respect to the most stringent safety and efficiency standards, we are ready to ensure the safe storage of spent fuels and continue our commitment to generating clean and sustainable energy for Brazil. The operation of the UAS (Complementary Dry Storage Unit for Spent Fuel) not only ensures the safety of the facilities but also reinforces the role of nuclear energy in the national energy matrix, with the potential for future reuse of used fuels."</p><p>Under a turnkey contract signed in 2017, Holtec of the USA supplied Eletronuclear with HI-STORM FW systems and related equipment for dry storage of used fuel from Angra units 1 and 2. Angra 1 is a Westinghouse-designed 609 MWe pressurised water reactor (PWR), while Angra 2 is a Siemens-designed 1275 MWe PWR. The units have different architectures and licensing bases, adding to the complexity of the project. Holtec modified their respective cask handling cranes and equipment for loading the fuel into the multi-purpose canisters and for moving the canisters to the dry storage facility.</p><p>The storage facility is designed to receive fuel elements after the cooling process in pools at the plants. They are stored in canisters made of steel and concrete to guarantee safety. It is a system which is used in the USA and is designed to withstand extreme events such as earthquakes and floods.</p><p>It includes physical security, radiation and temperature monitoring, an armoured access control centre and a storage warehouse with a technical workshop, designed and constructed by Holtec. The facility was constructed because the storage pools of both units were reaching full capacity."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Brazil" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Brazil</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/eletronuclear-used-fuel-storage-unit-gets-extended-licence" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/eletronuclear-used-fuel-storage-unit-gets-extended-licence</span></a></p>

Emil Jacobs - Collectifission<p>"Russian nuclear regulator Rostekhnadzor has approved a 15-year life extension to 2040 for the Beloyarsk nuclear power plant's unit 3, a BN-600 fast neutron reactor.</p><p>It follows a comprehensive assessment of the condition of the unit - including the reactor vessel and internal elements and heat exchanger supports - which concluded that the "equipment fully complies with all modern safety standards". The extension to 2040 will take it to 60 years of operation.</p><p>A large-scale modernisation programme began in 2009 which included the installation of a second reactor emergency protection system, an emergency dampening system using an air heat exchanger and a back-up reactor control panel. That allowed an extension for 10 and then a further five years to 2025. Further work has been carried out, including the replacement of steam generators and circulating pumps of the first reactor circuit as part of the further 15-year extension process.</p><p>Ivan Sidorov, director of Beloyarsk NPP, said: "Power unit 3 of the Beloyarsk NPP is a key link for the future of nuclear energy. It was here that the first assemblies based on used nuclear fuel - MOX fuel - were industrially tested, and now new assemblies are in the active zone to confirm the high quality of fuel and materials for future fourth-generation power units BN-1200M and BREST. Even more important is the invaluable knowledge of our personnel, obtained as a result of the reliable operation of fast neutron reactors."</p><p>The nuclear power plant operates units with fast neutron reactors with sodium coolants - the BN-600, connected to the grid in 1980, and BN-800, connected to the grid in 2015, are the world's largest such power units. The life extension will mean the unit can generate an extra 60 billion kWh of electricity.</p><p>The sodium-cooled BN-series fast reactors are part of Rosatom's Proryv, or 'Breakthrough', project to develop fast reactors with a closed fuel cycle whose mixed oxide (MOX) fuel will be reprocessed and recycled. As well as its generating capacity unit 3 is seen as strategically important in terms of testing technical solutions for future fast reactors such as the BREST-OD-300 fast reactor with lead coolant and the BN-1200 planned for Beloyarsk."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Russia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Russia</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/beloyarsk-bn-600-fast-neutron-reactor-gets-15-year-extension" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/beloyarsk-bn-600-fast-neutron-reactor-gets-15-year-extension</span></a></p>
Emil Jacobs - Collectifission<p>"Innovative reactor developer Newcleo said it has "deep appreciation" for the Italian government's "strategic interest and support for the company" after two ministers said the government plans to invest in the company as part of the country's reintroduction of nuclear energy.</p><p>Following talks on the development of new-generation nuclear power, a joint statement was issued by Italy's Minister of the Environment and Energy Security Gilberto Pichetto Fratin and Minister of Enterprise and Made in Italy Adolfo Urso. </p><p>"The two ministers confirmed their full agreement on the government's strategic interest in Italy's active participation in the development of innovative technologies in the sector, with a particular focus on the projects promoted by Newcleo, a leading Italian company in the design of advanced third-generation and fourth-generation reactors," it said.</p><p>It continued: "In fact, the government intends to provide concrete support to strengthen the national industrial supply chain dedicated to innovative nuclear energy, recognising its fundamental importance in guaranteeing the country's energy security, environmental sustainability and technological competitiveness."</p><p>According to a Reuters report, the government "could invest, through one or more state-controlled entities, as much as EUR200 million (USD216 million) in Newcleo".</p><p>Paris-headquartered Newcleo said that it welcomes the interest shown, adding: "We are pleased that the government intends to strengthen Italy's industrial position in this sector through concrete support for our company."</p><p>According to Newcleo's delivery roadmap, the first non-nuclear pre-cursor prototype of its lead-cooled fast reactor (LFR) is expected to be ready by 2026 in Italy, the first reactor operational in France by the end of 2031, while the final investment decision for the first commercial power plant is expected around 2029.</p><p>Earlier this month, Newcleo announced it is to collaborate with Italian designer, manufacturer and installer of machinery and plants for the iron and steel industry Danieli Group on integrating Newcleo's LFRs with Danieli's steelmaking technology.</p><p>In late February, Italy's Council of Ministers approved a draft law calling for the government to adopt a series of legislative decrees to create the legal framework for the reintroduction of nuclear power, which was phased out following a referendum in 1987. The government said the text is aimed at "the inclusion of sustainable nuclear and fusion in the so-called 'Italian energy mix' and intervenes organically from an economic, social and environmental perspective, within the framework of European decarbonisation policies with a time horizon of 2050, consistently with the objectives of carbon neutrality and security of supply".</p><p>The draft law has been submitted to parliament for final approval."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Italy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Italy</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/italian-government-eyes-investment-in-newcleo" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/italian-government-eyes-investment-in-newcleo</span></a></p>
Emil Jacobs - Collectifission<p>"The US Nuclear Regulatory Commission has renewed for a second time the operating licences of units 1-3 at Duke Energy's Oconee nuclear power plant in South Carolina for an additional 20 years.</p><p>The first two of the three pressurised water units at the plant were connected to the grid in 1973, and the third in 1974. They are currently licensed to operate to the early 2030s. Oconee is Duke Energy's largest nuclear power plant, with a total capacity of more than 2500 MWe, and the first for which it has submitted an application for subsequent licence renewal. The application was submitted in June 2021.</p><p>The Nuclear Regulatory Commission (NRC) said its review of the application proceeded on two tracks: a safety evaluation report was issued in December 2022, and a final environmental impact statement was issued in February 2025.</p><p>"The NRC's Atomic Safety and Licensing Board terminated the adjudicatory proceeding regarding the application in January 2025, concluding that no contested matters remained before it for resolution," the NRC noted. "The Board's decision has been appealed to the Commission. NRC regulations allow the licences to be issued while an appeal is pending. The Commission retains the ability to act on the appeal and, as needed, direct additional staff action on the licences."</p><p>The licenses now expire in February 2053 and October 2053, respectively, for units 1 and 2, and July 2054 for unit 3.</p><p>Duke Energy said the approval of its subsequent, or second, renewed licences enables Oconee to support the company's "'all of the above' strategy to deliver a path to cleaner energy while protecting reliability and affordability for customers as regional electricity demand continues to grow". </p><p>"Approval to extend Oconee Nuclear Station's licences is a significant milestone for Duke Energy and provides significant learnings to use in completing licence applications for our other plants," said Duke Energy Chief Nuclear Officer Kelvin Henderson. "As we address growth, modernise the fleet and invest in cleaner technologies, subsequent licence renewal helps ensure nuclear energy continues to be a vital part of Duke Energy's generation portfolio."</p><p>Duke Energy operates nuclear reactors at six sites in North and South Carolina: the three-unit Oconee plant, two-unit plants at Brunswick, Catawba and McGuire; and two single-unit plants at Robinson and Shearon Harris. In 2024, its six plants provided more than 50% of Carolina customers' electricity and more than 96% of the company's clean energy. Keeping its nuclear fleet operating is seen by Duke as key to achieving its carbon reduction goals of at least 50% by 2030 and net-zero by 2050 from electricity generation.</p><p>US reactors are initially licensed by the NRC to operate for up to 40 years - a period originally based on economic, rather than technology, limitations. An initial licence renewal extends those operating lives to 60 years. Subsequent licence renewal extends the period of operation from 60 to 80 years.</p><p>All Duke Energy nuclear plants have received initial licence renewal to achieve up to 60 years of operation. The company is working toward extending the life of all of its existing nuclear units up to 80 years, with plans to submit a licence renewal application for its Robinson nuclear power plant, also in South Carolina, later this month.</p><p>To date, US 12 reactors have been approved for operation to 80 years.

Emil Jacobs - Collectifission<p>"US Nuclear Regulatory Commission approval of the Principal Design Criteria Topical Report is a key milestone towards licensing Westinghouse's eVinci microreactor in the USA.</p><p>Principal Design Criteria - or PDCs - define how each part of the reactor's structures, systems, and components will function, and ensure that the design conforms to design bases outlined in US Nuclear Regulatory Commission (NRC) regulations. Approval of these criteria provides a clear path to licensing the eVinci microreactor for deployment as well as simplifying and streamlining the licensing process for customers, Westinghouse said.</p><p>Jon Ball, president of eVinci Technologies at Westinghouse, said the NRC approval gives customers confidence that the microreactor can be licensed for deployment in a highly streamlined and repeatable manner. "This will allow customers to take advantage of the eVinci microreactor's small size and transportability to rapidly deploy when and where they need them for cost-competitive and resilient power," he said.</p><p>The eVinci is a heatpipe-cooled microreactor which can produce up to 5MWe with a 15MWth core design. The TRISO-fuelled reactor core is designed to run for eight or more full-power years before refuelling, and the factory-built and assembled reactor can be shipped in a container to provide versatile, scalable energy for a variety of applications.</p><p>Westinghouse is currently engaged in pre-application activities with the NRC to support the eventual licensing of the eVinci microreactor. In December, the regulator approved the reactor's Advanced Logic System Version 2 instrumentation and control platform, making it the first microreactor with an NRC-approved I&amp;C system."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/US" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>US</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/pre-licensing-milestone-for-evinci" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/pre-licensing-milestone-for-evinci</span></a></p>
Emil Jacobs - Collectifission<p>"As Australia gears up for the federal election on 3 May, leading players in the Liberal-National Coalition have underlined the current opposition's plans for nuclear, should it be elected.</p><p>Prime Minister Anthony Albanese formally announced on Friday that the 2025 federal election will take place on 3 May. Albanese's Australian Labor Party won a majority at the last federal election in 2022. Australia has no nuclear power plants, although it has a research reactor and has three operating uranium mines - in 2022 it was the world's fourth ranking producer of uranium, all of which was exported.</p><p>The Liberal-National Coalition, also known as the LNP, is a long-running alliance of the Liberal Party of Australia, and the National Party. Last year, the LNP's leaders outlined their plans for nuclear power in Australia, and announced seven locations where plants could be built.</p><p>Speaking on Seven Network's Weekend Sunrise programme the day after the election was called, Liberal Party of Australia leader Peter Dutton reiterated the coalition's commitment to its energy plans, and used the UK as an example of the need for nuclear.</p><p>"The Labour Party in the UK have just announced that they can't reach net zero by 2050 without nuclear, and that's true in our country as well," he said. "So we need cleaner fuel and cleaner energy. We need to make sure that we've got cheaper energy. We're paying three times the cost for electricity of other countries at the moment, and that's what’s smashing families."</p><p>Dutton said nuclear capacity would not be available in Australia until the mid to late 2030s, so the coalition's policy would rely on gas to ensure reliability in the meantime. "The PM keeps talking about green hydrogen, but that's not going to work and power prices are just going to keep going up," he said, referring to the Labor Party's energy policy.</p><p>Separately, shadow energy minister Ted O'Brien said the role of Australia's nuclear regulatory body ARPANSA could be expanded to oversee nuclear power plants quickly. Speaking on Sky News Sunday Agenda, O'Brien said that this could be achieved "within a few years". A first small modular reactor could be in operation in Australia by 2035, he said, with a large-scale plant taking "couple of years" longer than that. Deployment of nuclear would then continue with the aim of reaching 14 gigawatts of nuclear capacity by 2050, he said.</p><p>Albanese has described the coalition's plan as a "nuclear fantasy". Speaking to reporters in Perth on Monday, the Prime Minister said: "We have a 2030 target, we're confident we'll meet it, and our policy is very clear ... our policy is for renewables, backed with affirming capacity of gas, batteries and hydro." Albanese's words were reported by AAP.</p><p>Under federal electoral law, it is compulsory for all eligible Australian citizens to enrol and vote in federal elections, by-elections and referendums."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Australia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Australia</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/energy-in-spotlight-as-australian-election-campaigns-begin" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/energy-in-spotlight-as-australian-election-campaigns-begin</span></a></p>

Emil Jacobs - Collectifission<p>"Industrial giant Dow and X-Energy Reactor Company have submitted a construction licence application to the US Nuclear Regulatory Commission for the proposed advanced nuclear project at Dow's Seadrift site in Texas.</p><p>Dow's proposed advanced small modular reactor (SMR) project - announced in May 2023 - is being developed by its wholly-owned subsidiary, Long Mott Energy LLC. The project is focused on providing Dow's Union Carbide Corporation Seadrift Operations manufacturing site with safe, reliable, and clean power and industrial steam replacing existing energy and steam assets that are near end-of-life. The project is supported by the US Department of Energy's (DOE's) Advanced Reactor Demonstration Programme, which is designed to accelerate the deployment of advanced reactors through cost-shared partnerships with US industry.</p><p>Since 2018, X-energy, and subsequently Dow, have worked with the Nuclear Regulatory Commission (NRC) through extensive pre-application engagements to demonstrate the safety profile of the Xe-100 advanced SMR through its advanced fuel design, passive safety features, and state-of-the-art analysis techniques. </p><p>"This has culminated in a comprehensive application submittal that exceeds NRC regulations for the protection of public health and safety, as well as the environment, with substantial safety features," the partners said in a joint statement.</p><p>Once the permit is received - which could take up to 30 months - and upon Dow confirming the ability to deliver the project while achieving its financial return targets, construction could begin, they said.</p><p>"This is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the US," said Edward Stones, business vice president, Energy and Climate, Dow. "We look forward to engaging with the NRC, DOE, our business partners and the community throughout the application process."</p><p>"The construction permit application is a critical step to deliver on the vision of Congress and DOE to position the US at the forefront of commercialising advanced reactor technology," said X-energy CEO Clay Sell. "Together with our world-class partner, Dow, we will demonstrate how the technology deployed at Seadrift, Texas, can be quickly and efficiently replicated to meet incredible power demand growth across America."</p><p>Once complete, Long Mott Generating Station is expected to be the first grid-scale advanced nuclear reactor deployed to serve an industrial site in North America.</p><p>Each Xe-100 high-temperature gas reactor is engineered to operate as a single 80 MW electric unit, optimised as a four-unit plant delivering 320 MWe, on a roughly 30-acre site. The reactor can provide baseload power to an electricity system or support industrial applications with 200 MW thermal output per unit of high-pressure, high-temperature steam.</p><p>According to Dow, its Seadrift site covers 4700 acres and manufactures more than 4,000,000 pounds (1816 tonnes) of materials per year for use in applications such as food packaging, footwear, wire and cable insulation, solar cell membranes and packaging for pharmaceutical products. Around 1000 people work at the site. The companies believe that the project will reduce the Seadrift site's emissions by about 440,000 tonnes of carbon dioxide equivalent per year.</p><p>Dow was one of several tech giants and other major energy users that last month signed a pledge supporting the goal of at least tripling global nuclear capacity by 2050. The announcement, at CERAWeek 2025 in Houston, Texas, in the USA, of the Large Energy Users Pledge, followed earlier pledges by 31 countries, by 140 nuclear industry companies and 14 major global banks and financial institutions to support the tripling goal.</p><p>X-energy was selected by the DOE in 2020 to develop, license, and build an operational Xe-100 advanced SMR and TRISO-X fuel fabrication facility. Since that award, X-energy has completed the engineering and preliminary design of the nuclear reactor, has begun development and licensing of a fuel fabrication facility in Oak Ridge, Tennessee, and has secured about USD1.1 billion in private capital to commercialise its technology."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/US" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>US</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/application-lodged-for-construction-of-texas-smr-plant" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/application-lodged-for-construction-of-texas-smr-plant</span></a></p>
Emil Jacobs - Collectifission<p>"Site analysis reports, flood studies and seismic safety studies - as well as technical feasibility studies by potential technology providers Westinghouse and EDF - are being carried out for the JEK2 project for new capacity at the existing Krško nuclear power plant in Slovenia.</p><p>In the latest update on the project to the municipal council, GEN energija's Chief Operating Officer Bruno Glaser set out the status of the studies and said that the main focus was on the siting of the new nuclear facility.</p><p>Nuclear operator Gen energija submitted its proposal for the preparation of the national spatial plan for the new capacity to the Environment, Climate and Energy Ministry in October with the company hoping that a decision will be taken by the end of the year to adopt the preparation of the national spatial plan.</p><p>This will be followed by the preparation of an environmental report as part of the environmental impact assessment and a cross-border environmental impact assessment. Meanwhile, introductory meetings were held with EDF representatives in mid-February and with Westinghouse representatives in early March, at which they "got acquainted with the location of the planned new nuclear power plant by viewing it from the roof of the GEN office building and the high-water embankments along the Sava River".</p><p>The JEK2 project team says that EDF and Westinghouse will complete their studies "in the third quarter of this year".</p><p>The background </p><p>Slovenia's JEK2 project is for a new one or two-unit nuclear power plant, with up to 2400 MW capacity, next to Krško NPP which has a 696 MWe pressurised water reactor generating about one-third of the country's electricity. Krško is owned and operated by Nuklearna Elektrarna Krško, which is jointly owned by Croatia's Hrvatska elektroprivreda (HEP Group) and Slovenia's GEN Energija.</p><p>The JEK2 project team, following discussions with potential nuclear power plant providers EDF, Korea Hydro &amp; Nuclear Power (KHNP) and Westinghouse, in May last year, estimated the cost for various reactor sizes, ranging from EUR9.314 billion (USD10.1 billion) for a 1000 MW unit, up to EUR15.371 billion for a 1650 MW unit. KHNP withdrew from the process in January, with GEN saying the decision was "based on an assessment of the current business environment and a change in their strategic business priorities".</p><p>Slovenia had been due to hold a referendum on new nuclear in November, but that was called off amid a political row over how it was being conducted. Prime Minister Robert Golob said he remained committed to holding a referendum before a final investment decision is taken - which is currently due to be in 2028."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Slovenia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Slovenia</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/siting-and-technical-feasibility-studies-under-way-for-new-nuclear-in-slovenia" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/siting-and-technical-feasibility-studies-under-way-for-new-nuclear-in-slovenia</span></a></p>
Emil Jacobs - Collectifission<p>"The Norwegian government has issued Norwegian Nuclear Decommissioning with a licence to own and operate the nuclear fuel and materials testing reactor at Halden, which it will decommission. Until now, the reactor has been owned and operated by the Institute of Energy Technology.</p><p>Established as an agency under the Ministry of Trade, Industry and Fisheries in February 2018, Norwegian Nuclear Decommissioning (NND) is responsible for decommissioning the research reactors and other related nuclear infrastructure, as well as the safe handling, storage and disposal of radioactive waste.</p><p>NND submitted an application in December 2022 for a licence to own and operate the two Norwegian nuclear facilities in Halden and Kjeller, as well as the operation of the waste landfill for low- and intermediate-level radioactive material in Himdalen. The current licence holder is the Institute for Energy Technology (IFE).</p><p>Norway's two research reactors - the nuclear fuel and materials testing reactor at Halden and the JEEP-II neutron scattering facility at Kjeller - were declared permanently shut down by IFE in June 2018 and April 2019, respectively.</p><p>The transfer of the licence for Halden from IFE to NND was approved earlier this month by the Norwegian Radiation and Nuclear Safety Authority.</p><p>The government has now granted the licence, which is valid from 1 April for an unlimited period, "but with the possibility of revocation".</p><p>"The licence includes the right to own, store, process, transport, possess and place nuclear material," the government noted. "The licence also includes the right to trade nuclear material, but only to the extent necessary to return irradiated fuel to the client or owner in accordance with return agreements previously entered into by IFE or that will be entered into by NND in the future. The licence does not include the right to export nuclear material out of the country ... If it becomes relevant at a later date, NND may apply for a permit for this."</p><p>The Halden reactor - which started up in 1959 - ran at a maximum power of 25 MWt and contained numerous test positions, thus providing flexible test conditions. The project was a joint undertaking of national organisations in 19 countries sponsoring a jointly financed programme under the auspices of the OECD Nuclear Energy Agency. The programme was financed by the participating countries and was renewed every three years. As the host country, Norway covered about 30% of the programme cost. In June 2018, IFE announced it would not apply to extend the reactor's operating licence, which expired in 2020, and the reactor, which was offline due to a safety valve failure, would not be restarted.</p><p>"This is a historic day," said NND Director Pål Mikkelsen. "Today we celebrate that we have reached an important milestone. At the same time, the work has just begun, and we have many exciting tasks ahead of us.</p><p>"Both NND and IFE will independently ensure the safety of their respective facilities. At the same time, we will continue our close and good cooperation. Partly to help each other in general, but also to facilitate a successful transfer of nuclear facilities in Lillestrøm and in Aurskog-Høland when the time comes."</p><p>NND said that since 2018 it has been "working on planning, licensing applications and preparing its own organisation to take over responsibility for Norway's historic nuclear facilities. Today's decision is the first part of the state taking over responsibility for all facilities associated with Norway's historic nuclear research programme"."</p><p><a href="https://greennuclear.online/tags/Nuclear" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Nuclear</span></a> <a href="https://greennuclear.online/tags/News" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>News</span></a> <a href="https://greennuclear.online/tags/Norway" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Norway</span></a></p><p><a href="https://www.world-nuclear-news.org/articles/transfer-of-halden-licence-completed" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">world-nuclear-news.org/article</span><span class="invisible">s/transfer-of-halden-licence-completed</span></a></p>
