Ukrainian War Refugee to Microreactor Entrepreneur: Building the N1 with Jonas Helwig

<p>Jonas Helwig is Swedish-born, French-passport-holding, and was living in Ukraine when the war started. He fled with his wife and their newborn daughter, ended up in Buenos Aires by accident, and his neighbor turned out to be a nuclear energy manufacturer.</p><p>Over dinner conversations with a pen and paper, they sketched out the N1, and Jonas joined the company. That's how Nuclearis Energy started.</p><p>In this episode, Jonas walks us through the N1 micromodular reactor: what it is, how it solves the efficiency problem that makes most microreactors uneconomical, why air-cooling changes where nuclear can go, how the design process started at the spent fuel and worked backwards, and what a "nuclear renaissance" actually means.</p><p><br /><strong>CONNECT WITH JONAS &amp; NUCLEARIS</strong><br /></p><p>Jonas Helwig on LinkedIn: Search "Jonas Helwig Nuclearis"</p><p>Nuclearis Energy website: <a href="https://www.nuclearisenergy.com/" target="_blank" rel="ugc noopener noreferrer">https://www.nuclearisenergy.com/</a></p><p>Nuclearis on X: Search @nuclearisenergy</p><p>Nuclearis on LinkedIn: <a href="https://www.linkedin.com/company/nuclearis-energy/" target="_blank" rel="ugc noopener noreferrer">https://www.linkedin.com/company/nuclearis-energy/</a></p><p><br /></p><p>- Atucha Nuclear Power Plants (Argentina): <a href="https://www.iaea.org/PRIS/CountryStatistics/ReactorDetails.aspx?current=388" target="_blank" rel="ugc noopener noreferrer">https://www.iaea.org/PRIS/CountryStatistics/ReactorDetails.aspx?current=388</a></p><p><br /></p><p><br /></p><p><strong>JOIN THE NUCLEAR WORKFORCE</strong></p><p>Companies like Nuclearis are gearing up for major engineering hiring.
