Last week, at the World Nuclear Symposium in London, Westinghouse’s Lou Martinez Sancho spoke during the Set for Success panel. She shared insights into how Westinghouse and the broader nuclear industry are shaping up to meet global opportunity, highlighting the significant advancements and achievements that will help drive progress in the years ahead. Also speaking in the Knowledge Zone was Caitlin Touhey, Senior Commercial Manager, on the Investing in Leaders: Why Organisations Send People to the Summer Institute panel. Caitlin reflected on her personal development journey at the Summer Institute and highlighting the importance of investing in the next generation of nuclear professionals. #Westinghouse140 #NuclearSympo #Symposium2026 #NuclearEnergy

The World Nuclear Association (WNA) Symposium 2026, From Ambition to Action, took place last week in London, and Westinghouse leaders led important discussions throughout the conference. Attendees heard from Westinghouse’s new President of Global Operating Plants, Gaby Poirier, during his Fireside Chat with Neil Cooper from Great British Energy – Nuclear. Drawing on his industry experience, Gaby shared insight about his industry experience that he can bring to the nuclear industry and Westinghouse. We also attended Canada-UK Nuclear Day: From Ambition to Delivering - Building the Canada-UK Nuclear Partnership, where opening remarks were delivered by Michael Shanks MP, Minister of State for the Department for Energy Security and Net Zero (DESNZ). #westinghouse140 #NuclearSympo #Symposium2026 #NuclearEnergy

A defining moment for the next frontier of nuclear and for Westinghouse’s eVinci™ microreactor technology! On Sept. 3, the eVinci technology successfully completed zero-power, high-temperature criticality testing at 663°C, generating high-quality experimental data at temperatures representative of future operating conditions. This achievement helps validate key design assumptions, strengthens our analytical models and provides valuable insights that will guide future prototype development. “American innovation has always been the driving force behind American energy dominance,” said Chimi Zacot, Deputy Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE). “Westinghouse’s progress on the eVinci microreactor is another great example of that ingenuity at work.” Thank you to our partners at U.S. Department of Energy (DOE) and Los Alamos National Laboratory, as well as the National Criticality Experiments Research Center, a National Nuclear Security Administration (NNSA) facility at Nevada National Security Sites, for helping make this achievement possible.

The future of nuclear energy is moving forward with momentum – from optimizing operations and expanding power capacity to deploying advanced reactors – and embracing innovation at every step. That momentum was on full display at NECX this week, where we joined more than 1,400 attendees from across the nuclear industry who came together to discuss the opportunities and challenges shaping our path forward. The message was clear: the global demand for nuclear is growing, and the industry is ready to collaborate, innovate and rise to the challenge. Westinghouse was proud to be part of the conversation. Vice President of New Plant Project Development James Wyble, III and Executive Vice President of Corporate Affairs Margaret Cosentino shared insights during plenary sessions on advanced reactor deployment and scaling technologies globally. Leaders Nathan Harsch, Susan Baier and Mike Drudy contributed as panelists in educational sessions focused on supply chain risk and compliance, extended power uprates and using technology to combat obsolescence. Thank you to Nuclear Energy Institute and American Nuclear Society for jointly hosting this valuable and energizing event! #NECX2026 #WestinghouseProud #NuclearInnovation #AdvancedReactors

Five years of Westinghouse in Poland. What a journey it has been! Since opening our doors in 2021, Westinghouse Poland has grown into a thriving team of nearly 500 professionals whose talent and dedication continue to drive our success. Over the past five years, we have built strong teams in Kraków, expanded our capabilities, supported projects across Poland and around the world and made meaningful contributions to the communities where we live and work. But our story is about more than growth. It is about being a part of Poland's nuclear energy future. From supporting the country's first nuclear power plant project to helping develop the expertise and capabilities needed for long-term energy security, our teams are contributing to a transformational journey that will have a lasting impact for generations to come. As we celebrate this milestone, we are proud of everything we have achieved together and grateful to our employees, customers and partners who have been part of the journey. Here’s to the first five years and to the many years and opportunities ahead! #WestinghousePoland #WestinghousePoland5Years

We've been connecting with industry leaders at NECX this week, where utilities, advanced reactor developers, suppliers, regulators, and innovators have come together to focus on operations, deployment, and real-world progress across the nuclear energy sector. Westinghouse leaders and subject matter experts have participated in plenary and educational sessions, speaking on key topics including: ⏺️ Advanced reactors ⏺️ Extended power uprates ⏺️ Digital strategy & fleet sustainability using AI & data ⏺️ Deploying U.S. technology globally ⏺️ Next generation of large reactors ⏺️ Managing geopolitical risk & compliance We’ve enjoyed meeting everyone at booths 307 and 309 in the exhibit hall and sharing how our latest technologies are supporting today’s operating nuclear fleet and shaping the future of new reactor deployment. There’s still time to stop by and connect with our team! 👋 #NECX2026

A major step forward for advanced nuclear innovation: Westinghouse has completed zero-power criticality testing for the eVinci™ microreactor in partnership with Los Alamos National Laboratory and Idaho National Laboratory at the National Criticality Experiments Research Center, a National Nuclear Security Administration (NNSA) facility at Nevada National Security Sites.
