Physics Episodes

Ed McGinnis said something in our last episode that's hard to shake: 96% of the energy in spent nuclear fuel has never been touched. The physics checks out. But what happens when countries actually try to get that energy back? This After Pop digs into the history of nuclear fuel recycling, not the theory, but the track record. France, the UK, Japan. Staggering sums of money. Complicated results. And a 1977 executive order that changed everything. We break down what PUREX actually does, why Jim...

Imagine filling up your car at a gas station in Washington, DC, and heading toward Richmond. Twenty miles down the road, you pull over, call a tow truck, and scrap the car, with 96% of the fuel still in the tank. That's what we do with nuclear fuel in the United States right now. Ed McGinnis is the CEO of Curio and a former senior official at the U.S. Department of Energy. He's spent decades in nuclear policy and energy security, and he's now building something that could change how we think ab...

Dr. John Zino stood in front of a room of engineers, technicians, and career-changers and told them a nuclear reactor is "just boiling water." Jaws dropped. Really? That's it? Well, yes. And also, that little word "just" is hiding one of the most elegant chains in all of engineering. In this After Pop explainer, we follow a single uranium atom from the moment it splits to the moment your phone starts charging. Fission to heat. Heat to steam. Steam to a spinning shaft. Spinning shaft to electri...

What does it actually look like to spend nearly 40 years inside the nuclear industry, from submarine shielding to the Department of Energy to the cutting edge of small modular reactor design?Dr. John Zino is a Chief Consulting Engineer at GE Vernova Hitachi Nuclear Energy and an Associate Teaching Professor at NC State University. In this episode, he breaks down the BWRX-300 — a 10th-generation boiling water reactor that strips nuclear power down to its simplest form. No massive recirculation pu...

What is Reactor Physics? Following up on the Ikhwan Khaleb episode, Danielle breaks down reactor physics — the science of keeping chain reactions balanced, safe, and useful. From the neutron lifecycle to criticality to the tools reactor physicists actually use. Key topics: – What reactor physics actually is (popcorn analogy!) – The neutron lifecycle: birth, fast childhood, slowing down, useful work, absorption – Criticality: subcritical, critical, and supercritical – Tools of the trade: ne...

Black History Month Spotlight: Dr. Shirley Ann Jackson - Pioneering Physicist and Innovator Welcome to another special episode of Naked Nuclear for Black History Month! We spotlight the illustrious Dr. Shirley Ann Jackson, a groundbreaking physicist who broke barriers from MIT to Bell Labs and even the U.S. Nuclear Regulatory Commission. Learn about her early life, groundbreaking research in condensed matter physics, and contributions to telecommunications technology like touch-tone phones and...

It's an alphabet soup, but somebody's gotta break it down. Join us in this exciting episode of 'After Pop! A Breakdown of Nuclear Reactor Types,' with your host Danielle. We'll explore the fascinating world of nuclear reactors, learning how they work and discussing various types like Boiling Water Reactors (BWRs), Pressurized Water Reactors (PWRs), Small Modular Reactors (SMRs), Micro Reactors, and Advanced Reactors including Molten Salt Reactors. Discover the benefits, safety measures, and fu...

In this episode of Naked Nuclear, Danielle sits down with Steve Rea, the 2024 recipient of the American Nuclear Society Landis Public Communication and Education Award . Steve, a 30-year nuclear industry veteran, discusses his transition to public education and nuclear advocacy in North Carolina. From his beginnings in nuclear chemistry in high school to forming the Nuclear Advisory Council, Steve shares insights on the role of diverse energy sources and the importance of communicating nuclea...

Understanding In-Situ Leaching with Dr. Kreamer In this episode of Naked Nuclear, host Danielle Allen delves into the technical aspects of in-situ leaching (ISL), a method that accounts for 80% of uranium mining in the U.S. Following up from the previous episode with Dr. David Kreamer, this explainer breaks down the ISL process, ingredients in lixiviant, and steps taken to ensure groundwater safety. The episode emphasizes ISL's efficiency and minimal environmental impact, using simple analogie...

The After-Pop! Demystifying Ionizing and Non-Ionizing Radiation Welcome back to Naked Nuclear, where we simplify nuclear technology. In this episode, we dive into radiation—its origins, types, and measurements. Learn about non-ionizing and ionizing radiation, explore their sources, and understand how we measure radiation exposure. Discover the three types of ionizing radiation: alpha, beta, and gamma. We also discuss how to stay safe with guidelines on dose, time, and exposure limits. Join us...

Welcome to the Ep.1 After-pop! Nuclear Fuels Breakdown: Uranium Oxide, Uranium Silicide, Uranium Mononitride, and HALEU In this quick follow-up episode, we dive deeper into the world of nuclear fuels. Dr. Jennifer Watkins breaks down the key materials used in advanced nuclear reactors, including: Uranium Oxide (UO₂): The most common nuclear fuel, typically used in light water reactors. Uranium Silicide (U₃Si₂): A high-density fuel offering improved performance in reactors. Uranium Mononitri...
