What were the big nuclear energy stories of 2025? What to watch out for in 2026...

The World Nuclear News team looks back over the most read articles in 2025 - with topics including Canada's ground-breaking SMR project, the 50th World Nuclear Symposium, the eventual signing of a contract for the Czech new nuclear project, China's SMR completing cold testing, and the drone damage to Chernobyl's New Safe Confinement.Then World Nuclear Association Director General Sama Bilbao y León picks out the key themes of the year, noting the fast-growing interest from the financial sector in investment opportunities in nuclear, plus the declaration from energy users such as Google, Meta and Dow Chemicals to support the goal of at least tripling nuclear energy capacity by 2050.With a number of projects making progress in countries without recent experience of nuclear construction there has also been a lot of focus on developing supply chains, reflected in the success of the World Nuclear Supply Chain conference held in Poland.Looking ahead to 2026 there are big set-piece events to look forward to - such as World Nuclear Symposium in London, World Nuclear Supply Chain conference in the Philippines and World Nuclear Fuel Cycle conference in Monaco - with big moments also expected for the first units in Bangladesh and Turkey, a restart for Palisades as well as first concrete due to be poured for Hungary's Paks II project.Bilbao y León says the "stars are definitely aligned" for nuclear and the coming year "is the moment where the global nuclear industry really needs to be proactive and active and make the most of this opportunity". She says: "We really need to work together with our governments. We need to work together with the nuclear regulators, with the finance community, with large energy users. And we cannot leave behind civil society. We have seen major improvements in acceptance and interest in nuclear, but we need to continue to be very proactive to engage with civil society, to make sure that no question is left unanswered."Key links to find out more:World Nuclear NewsCanada's first SMR project: How is CAD20.9 billion cost calculated?World Nuclear AssociationEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

Nuclear energy is now widely seen as one part of the solution to reducing carbon emissions. But how much of a profile did it get at COP30 - the 30th UN Climate Change Conference, held in Belém, Brazil?Jonathan Cobb, Senior Programme Lead, Climate, for World Nuclear Association, was in Brazil for the event and in this edition he outlines what was achieved, and not achieved, at COP30 and what the significant moments were for nuclear energy.He looks ahead to the next editions of COP - in Turkey and Ethiopia - before COP33, which will be held somewhere in Southeast Asia in 2028, and which is due to be when all the National Determined Constributions will have to have been submitted, with a new global stocktake document to be agreed.Also in this edition we hear from Thomas Lamb, CEO of Myriad Uranium, who talks about the history of, and his hopes for, their Copper Mountain project in Wyoming in the USA. He also considers the impact of AI on uranium exploration.Key links to find out more:World Nuclear NewsEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

Johan Svenningsson is Country Chairman and CEO of Uniper Sweden as well as being vice chairman and chairman-elect of World Nuclear Association.In this edition, Svenningsson talks about what has been an eventful few years for the nuclear energy sector in Sweden, and the current positive mood towards nuclear and plans for new nuclear - "it's fantastic, we're basically talking about nuclear 2.0 in Sweden", is how he puts it.We also hear about: lessons on modular construction from his previous roles in the oil and gas and the pharmaceuticals industry; life-extension work; decommissioning programmes; and how the construction of a deep geological repository is progressing.Regarding his role with World Nuclear Association, Svenningsson says nuclear is a unique global industry where people learn from each other and share knowledge: "I don't see any other industry which is that global and which is that integrated - we're all competitors, suppliers, customers but we really focus on, and want, nuclear to be a strong part of the future, greener society."His priorities for the association are the industry's need to deliver, now that the political and financial conditions are increasingly in place. He says that on the political and regulatory front "we've come a long way. I think nuclear is starting to be more on par with other technologies, but there is still a way to go. People are still talking about renewables or nuclear ... we should look at all these technologies to be fossil free".Other priorities include the need to attract and train a diverse selection of young talented people to the nuclear industry, and also to develop the supply chain as new nuclear projects begin in emerging nuclear countries, or in established countries restarting their nuclear construction programmes after decades. Key links to find out more:World Nuclear NewsDismantling of Swedish reactors reaches milestoneSweden looks to protect nuclear investors from political U-turnsExtended operation of Oskarshamn 3 to be assessedWNA Board membersEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

If global nuclear energy capacity is to at least triple by 2050 it is going to need huge, huge investment - estimates suggest $250billion a year for 25 years. So how will it be financed and what are the opportunities and challenges for financiers wanting to get involved? To find out more, host Alex Hunt is joined by World Nuclear Association's Lola Infante, Senior Programme Lead Economics and Finance, and David Stearns, nuclear finance advisor and consultant.They consider why nuclear projects have generally been state-financed in the past, and what the industry needs to do to ensure that it attracts private finance for future schemes, including "financing by design" where, as David puts it, "you embed and you write the financial coding at the same time that you're doing your site assessment, at the same time that you're checking your early stage regulatory approvals".There is discussion of the growing appetite by global investment banks and multilateral banks to invest in new nuclear and the challenges of structuring financing to ensure it is attractive despite the long timescales involved in planning, building and then operating a new nuclear power plant.They also provide insights into what has been learned so far from the Financing Nuclear Briefing series, which brings the nuclear industry and financiers together to discuss financing issues under Chatham House rules.Key links to find out more:World Nuclear NewsInvestment decisions needed to avoid fuel cycle supply gaps'Difficult to overstate demand from institutional investors' for nuclearEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

More than 1,100 people gathered in London for the 50th World Nuclear Symposium, taking part in a packed programme of discussions, panels and networking. In addition to the usual broad range of topics there were also two special full day programmes - one focused on end energy users and one on finance.The event also saw the publication of 2025's World Nuclear Fuel Report, which warned that gaps could be opening up in the supply-demand picture over the coming years and investment decisions need to be taken now to fuel the forecast increase in nuclear power capacity.The World Nuclear News team were there and have put together a series of reports on the symposium's proceedings, and the fuel report's findings.People featured, in order of appearance:Cecile Gregoire-David, Head of Uranium, Conversion and Enrichment Services, EDFMalcolm Critchley, CEO, ConverDynMeirzhan Yussupov, CEO, KazatompromMichael Huebel, Director General, Euratom Supply AgencySama Bilbao y León, Director General, World Nuclear AssociationTomass Ehler, Director General for Nuclear Energy, Ministry of Industry and Trade, Czech RepublicLauren Culver, Senior Energy Specialist, World BankLoyiso Tyabashe, CEO, South African Nuclear Energy CorporationMatt Firla-Cuchra, Global Lead Nuclear Energy, KPMGVictoria Kalb, Global Head ESG & Sustainability Research, UBSMark Muldowney, Energy, Resources and Infrastructure, BNP ParibasLee McDonough, Director General, Net Zero, Nuclear and International, UK Department for Energy Security and Net ZeroMichelle Catts, Senior Vice President Nuclear Programmes, GE Vernova Hitachi Nuclear EnergyPete Bryant, CEO, World Nuclear Transport InstituteBernard Fontana, Chairman and CEO, EDFVakis Ramany, Senior Vice President International Nuclear Development, EDFLeon Flexman, Corporate Affairs Director, X-energyMesut Uzman, Chief Nuclear Officer, Fermi AmericaRita Baranwal, Chief Nuclear Officer, RadiantRaquel Heredia Silva, World Nuclear AssociationKey links to find out more:World Nuclear NewsInvestment decisions needed to avoid fuel cycle supply gaps'Difficult to overstate demand from institutional investors' for nuclearWorld Nuclear Fuel ReportWorld Nuclear SymposiumEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

Nuclear reactors worldwide generated 2667 TWh of electricity in 2024, beating the previous record high of 2660 TWh which was set back in 2006, according to World Nuclear Performance Report 2025. In this edition Jonathan Cobb, author of the report, outlines the key findings of the latest edition of the annual World Nuclear Association publication, which include the dominance of Asia in terms of new reactor capacity over the past decade.There is also clear evidence that reactor performance does not decline with age - the reverse can be true with modernisation, uprates and long-term operation programmes helping capacity factors reach an average of 83% across the global fleet (the capacity factor is a percentage of what the output would have been if a reactor had operated at full capacity for every moment of a year).Jonathan, who is senior programme lead, climate, at World Nuclear Association, also considers how likely it is that the record is going to be broken again in the next few years.Key links to find out more:World Nuclear NewsWorld Nuclear Performance ReportEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

Andy White, senior vice president of Energy and Environment International for Amentum, talks about his background and the work Amentum is doing in the UK and across Europe in the nuclear sector.Among the topics covered:* The change of attitudes which means that the future decommissioning process is included in the planning stages for new nuclear (and how that should reduce the number of 'surprises' when decommissioning plants)* The company's work on new nuclear in the UK at Hinkley Point C and Sizewell C and SMRs and operations in Poland, France, the Czech Republic as well as Norway and the Netherlands* The benefits of bringing in technology, skills and people from other sectors (and countries) to help with what looks like being a forthcoming rapid expansion of new nuclear. * Plus Amentum's nuclear fusion work, including at ITER, and the general outlook for nuclear, and how financing and regulation can help industry meet the demand for new capacityWe also bring you Claire Maden's conversation with Nima Ashkeboussi, vice president government relations and communications at Global Laser Enrichment, earlier this year at the World Nuclear Fuel Cycle conference in Canada.In it he talks about the company's laser enrichment technology, explaining how it works and the big plans the company has - including 30-years' worth of work relating to the US Department of Energy's 200,000+ tonnes of depleted uranium. GLE's plan is to re-enrich this, so cleaning up a stranded asset and in the process providing a new source of fresh fuel.GLE began a large-scale enrichment demonstration programme in May, and the US Nuclear Regulatory Commission accepted for review the company's licensing application for a new facility to be built at Paducah, Kentucky earlier this month.Key links to find out more:World Nuclear NewsAmentumGLEGLE submits full application for laser enrichment facility licenceAmentum, Multiconsult to assess Norway's nuclear optionsAmentum awarded Sizewell C project management contractEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

Nuclear energy lawyer Vince Zabielski, partner at Pillsbury Winthrop Shaw Pittman, has advised on numerous nuclear energy projects across the world, including the UAE nuclear new-build programme as well as those in Turkey, Bulgaria and the United Kingdom.A mechanical engineer before moving into law, he tells host Alex Hunt about the haircut that launched his career in nuclear, his switch to the law, and explains the important role played by nuclear energy lawyers which is, he says, essentially "problem solving", for example finding a path forward on risk allocation to allow what are giant projects to go ahead.Based in Pillsbury's London office, Zabielski talks about the recent announcements from the UK about Sizewell C funding and explains the benefits of the Regulated Asset Base financing system which is being used there, rather than the Contracts for Difference system used at the Hinkley Point C project and explains why he hopes the RAB system will be adopted elsewhere in Europe.He also talks about the challenge ahead to meet the ambitious goals for future nuclear energy capacity, including how regulators can help. And he explains why he'd encourage young people to consider a career in nuclear power.Also in this episode, in the news round-up, Claire Maden reports on the UK Government taking the Final Investment Decision on Sizewell C - which will feature two EDF EPRs with a capacity of 3.2GW - and the finalising of the project shareholdings. She also outlines the key findings of the OECD Nuclear Energy Agency's Small Modular Reactor Dashboard, which has identified 127 different SMR designs around the world.Key links to find out more:World Nuclear NewsSizewell C gets final go-ahead decisionThere are now 127 different SMR designs, finds NEA reportThe NEA SMR Digital DashboardPillsbury: Vince ZabielskiEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.

There are big expectations for large-scale growth in nuclear energy capacity over the coming years.  That's good news for established technology providers and their partners. But new capacity in new locations means that there are going to be big opportunities (and challenges) emerging. This was the focus for World Nuclear Association’s first World Nuclear Supply Chain event, held in Poland. There were more than 300 attendees from 27 countries, including government and industry delegations from Canada, China, Japan, Poland, South Korea and Sweden. As well as extensive networking opportunities there was a succession of high profile speakers taking part in panel sessions.World Nuclear News's Warwick Pipe was there and reports on the event.This episode features, in order of appearance,Sama Bilbao y León, World Nuclear AssociationVakis Ramany, EDFGreg Thede, AeconGary Rose, AtkinsRéalisJon Franke, Ontario Power GenerationJanne Mokka, FortumHiroyuki Goto,  Kansai Electric Power CoGareth Vaughan, AmentumPawel Gajda, Polish Ministry of IndustryRafal Kasprów, Orlen Synthos Green EnergyCarl Berglof, Swedish government's National Nuclear New Build CoordinatorAndy Fry, GE Vernova HitachiCosmin Ghita, NuclearelectricaRuth Todd, Rolls-Royce SMR Marc Tannenbaum, EPRIShuo Kan, China Nuclear Power EngineeringVivek Sharma, Adani Nora Signor, EDFGary Wolski, Curtiss-WrightJeremy Harrison, Government of SaskatchewanKey links to find out more:World Nuclear NewsWorld Nuclear Supply Chain conferencePolish supply chain gears up for country's first nuclear projectEmail newsletter:Sign up to the World Nuclear News daily or weekly news round-upsContact info:[email protected] credit:  Presenter Alex Hunt.
