Season 4 Coming Soon!

Imagine building something today that has to stay safe for tens of thousands of years! That’s the mind-bending challenge behind long-term nuclear waste storage, and in this episode, we’re diving deep into how Canada is pulling it off.Jordan and Mary sit down with Lisa Frizzell from the Nuclear Waste Management Organization (NWMO) to unpack how one of the most complex infrastructure projects in the world is being designed to protect people and the planet for basically forever. From solid ceramic fuel pellets and copper-coated steel canisters buried beneath 500 meters of rock, to the Indigenous-led, community-driven process that chose the final site, Lisa walks us through every layer of science, safety, and social trust built into the plan. Visit us at www.nei.org/fissionary.Music used in this episode was created by Beat Mekanik

We've sent humans to space and robots to Mars. The next leap? Sending nuclear reactors that can power the future, space life, and beyond.Joining us today is Dr. David Poston, the reactor designer behind NASA’s Kilopower project and one of the leading minds in the push to bring compact, resilient nuclear systems to space. From Krusty and DUFF (yes, those are Simpsons references) to his disruptive new company, SpaceNukes, David walks us through how we power life far from Earth and why nuclear is the right fuel source for the job. Visit us at www.nei.org/fissionary.Music used in this episode was created by Beat Mekanik

What do ChatGPT, cloud servers, and nuclear reactors have in common? More than you think. As AI expands and tech giants scramble for energy that’s clean, constant, and scalable, nuclear power is stepping into the spotlight. In this episode, Mary and Jordan sit down with Faraz Ahmad, the former head of Amazon’s global clean energy team, to explore why Big Tech is betting on nuclear. With a résumé spanning GE, NextEra, and British Nuclear Fuels, Faraz offers a rare insider’s look at why nuclear is becoming essential infrastructure for the digital age.Visit us at www.nei.org/fissionary.Learn more about nei.org/soti2025Music used in this episode was created by Beat Mekanik
