Radiant

Just 10 days ago, the Radiant team successfully completed our passive cooldown demonstration with a full-scale, non-nuclear prototype of our Kaleidos reactor! When raising our Series B, we set the goal of completing this test by Q3 2024 and our team crushed it! - Electric heaters applied up to 130kW to heat over 10 tons of steel and precision machined graphite. - Over 300 channels of instrumentation collected temperature, pressure, and flow data. - 12 valves opened upon being commanded to shutdown to allow air to flow and cool the pressure vessel via natural convection. - The test was performed at over 420 °C and the vessel took about 30 hours to return to ambient temperature. - Initial comparison against our thermal models shows that cooling is sufficient with the current design! Thank you to Brian Smith and Eric Wesley for your opening remarks, to the National Reactor Innovation Center | NRIC team for their continued support as we work towards a fueled test in the Idaho National Laboratory DOME facility, and to everyone who was able to join us in witnessing this milestone! Further planned testing will fully investigate fault tolerance and combination stress cases to make a high reliability reactor product.

Radiant is proud to announce our partnership with T3 Alaska at the University of Alaska Fairbanks! Our partnership supports essential programming, including STEM problem-based learning, post-secondary and career preparation, and community engagement strategies for Alaska’s students. In July, Radiant’s engineers mentored high school students on nuclear energy and nuclear microreactors during the Energy and Climate Advanced Summer Session. Our take: This curious and passionate cohort blew us away! Radiant engineers Daniel Berlin and River Bennett fielded great questions, ranging from how fission works to the heat transfer properties of Kaleidos’s helium coolant. Daniel and River also provided students with hands-on experience using radiation detection instrumentation. We’re excited to continue this partnership with the support of the University of Alaska Fairbanks, the College of Engineering and Mines, and the Alaska Center for Energy and Power (ACEP), as we work together to build the next generation of nuclear engineers and advocates for nuclear energy! #STEM #Engineering #Mentorship #NextGen

Definitely Not Boring. The Radiant Plan describes the path we’re taking to build the first portable nuclear reactor and how we’ll use it to power industrial change today and power interplanetary exploration tomorrow. What does it take to build a nuclear reactor from scratch and why is it critical we do so now? Radiant CEO and Founder Doug Bernauer sat down with Packy McCormick for a deep dive on uncovering the potential of portable nuclear, how he started a company in a pandemic, and what this game-changing technology means for all of us. Read on for never before seen pictures of Doug’s front yard wheat farm, insight into the Radiant Plan and how we plan to use portable microreactors to improve life on earth and power civilization off it. https://bit.ly/nbradiant

🎥 Hardware Hard at Work!  🎥 Last week, Radiant’s skilled team effortlessly installed 37 electrically heated hexagonal graphite core blocks into a solid stainless pressure vessel in preparation for a physical demonstration of our passive cooldown system. The system assembled in this timelapse integrates major subsystems of the Kaleidos reactor design. In a few short weeks, we will use this system to validate the unique heat transfer models already established through our digital twin.  As we continue to make progress towards a 2026 fueled test, we’re pleased to provide this sneak peek into the hardware behind the passive cooldown system of the world’s first truly portable nuclear reactor. Thank you to everyone involved in this project for your hard work and commitment. Let’s continue to push the boundaries of innovation and create a brighter, cleaner future!  #NuclearEnergy #Innovation #Sustainability #CleanEnergy #Engineering 

The Radiant team is in Washington, DC today to discuss advanced nuclear technology's role in the clean energy future we're working towards at the Environmental and Energy Study Institute and the House and Senate #RenewableEnergy and #EnergyEfficiency Caucuses. Head of Business Development Brice Nzeukou will be on a panel discussing workforce development at 3p EDT. If you're in Washington, DC and want to learn more about Radiant's plans for the future of #cleanenergy, you can join the EESI 2024 Policy Forum in person and give a big hello to Brice, Dylan, and Chris! Can’t make it in person? Watch the event live online here: https://lnkd.in/gt_AiaRU #DCEnergyExpo #cleantech #jobs

🏅 Exciting News! 🏅 We are thrilled to announce that Radiant has been named to the 2024 NatSec100 list by the Silicon Valley Defense Group, recognizing the top-tier startups in defense and national security. This acknowledgment highlights our dedication to advancing national security through innovative clean energy solutions. Our Kaleidos microreactor, a portable, zero-emissions power source, is designed to replace diesel generators, providing sustainable and reliable energy for remote regions and critical operations. This recognition underscores the impact of our work in addressing some of the most pressing energy challenges. We are proud to stand alongside other trailblazing companies committed to enhancing our national security. This accolade is a testament to the hard work and passion of our incredible team, and we are excited to continue driving forward with our mission. Thank you to JPMorganChase and the Silicon Valley Defense Group for this recognition. Together, we are building a more resilient and sustainable future. #NatSec100 #Innovation #CleanEnergy #RadiantIndustries #NationalSecurity #Sustainability #TechForGood Learn more about our journey and innovations: https://lnkd.in/dyVMFr4P

We see builders looking into nuclear not only at hyperscale levels for big-tech users, but for containerized micro data centers paired with Kaleidos reactors too. This combination will allow small-to-medium-sized businesses scale data needs flexibly and on time, while also meeting their clean energy goals. With increasing demands on power generation, it's more important than ever to invest in clean-power technologies including micro and small modular reactors. As the The Wall Street Journal reports today, tech companies are "willing to pay a premium for nearly uninterrupted, carbon-free power". This is the power people want, and the power companies need for the future. Read more here: https://lnkd.in/g9iQQ6QR Jennifer Hiller Sebastian Herrera

Congratulations to the team that assembled, and pressure-proof tested our passive cooldown test pressure vessel! The vessel successfully passed a hydrostat test where it was pressurized to 1.3x its rated pressure. This milestone brings us closer to our test this summer. Onwards!
