    It's Not Actually Waste: How CURIO is Tackling the Nuclear Waste Problem with Ed McGinnis

    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 about nuclear waste entirely. Spoiler: he doesn't even call it waste. He calls it "slightly used fuel." In this episode, Ed breaks down why the U.S. stopped recycling nuclear fuel in the 1970s, what went wrong with the Cold War-era Purex process, and how Curio's NuCycle technology does it differently ... without ever separating pure plutonium. We get into the $50 billion Nuclear Waste Fund that was collected from ratepayers and spent on other things, why the DOE is now paying over a billion dollars a year in court-ordered damages, and how 90,000+ metric tons of used fuel sitting at reactor sites across the country is actually the largest above-ground energy reserve in the world. Plus: Curio's planned recycling facility, bigger than a football stadium, processing more fuel than every other recycling facility on the planet combined, and the 3,000+ trades-based jobs it would create at around $125K a year for 60+ years. Topics covered: Why only 3-4% of nuclear fuel is actually used — and 96% is still usable energyThe difference between the Cold War Purex process and Curio's NuCycle technologyPresident Carter's ban on fuel recycling and the $13+ billion in lost investmentsHow recycling reduces radiotoxicity from 100,000+ years to about 300 yearsCurio's partnership with Oak Ridge National Laboratory since 2019The Nuclear Waste Policy Act, the $50 billion fund, and the billion-dollar-a-year lawsuit payoutsRussia still providing 20%+ of U.S. nuclear fuel — and what that means for energy securityCurio's planned facility: 4,000 metric tons per year, 3,000+ jobs, mostly tradesCurio's own SMR and micro-reactor designs (TrueFuel) Resources: Learn more about CURIO: curio.energy Jimmy Carter's Ruling on Reprocessing Spent Nuclear Fuel: https://www.nrc.gov/docs/ml1209/ML120960615.pdf

    After-Pop! Megawatts Thermal vs Electric?

    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 electricity. Four conversions, one pinky-tip-sized fuel pellet, and a reactor design that gets safer by removing the parts that can break. We'll also answer the question everyone asks once they see the numbers: if the BWRX-300 makes 870 megawatts of heat, where do the other 570 go? Bring your curiosity. No PhD required. The fuel chain, demystified. Pellet → fuel rod → assembly → core, and why the reactor core is really a very expensive water heater.BWR vs. PWR in plain English. Why a boiling water reactor uses one water loop while a pressurized water reactor uses two, and what the BWRX-300 gets to skip.The two numbers in the name. 870 MW thermal, 300 MW electrical, and why that gap is physics, not a flaw.How a turbine actually works. The garden-hose analogy, high- and low-pressure stages, and why the shaft has to spin at exactly 1,800 RPM on a 60 Hz grid.Faraday's 1831 trick. A magnet, some copper, and the moment motion becomes electricity.The Carnot limit. Why every thermal plant on Earth, coal and gas included, has to dump roughly two-thirds of its heat, and why that's why plants sit next to water.The BWRX-300's quiet superpower. Natural circulation and the passive isolation condenser. You can't break the pumps when the pumps aren't there.~870 MWt / 300 MWe — total heat output vs. electricity delivered for the BWRX-300~33–35% — typical thermal efficiency of a nuclear plant (roughly a third of the heat becomes power)~7 grams ≈ 1 ton of coal — the energy in one uranium fuel pellet, about the size of your pinky tip1,800 RPM at 60 Hz (US/Americas) / 1,500 RPM at 50 Hz (Europe, most of Asia) — turbine speed locked to grid frequency1824 & 1831 — Carnot's limit on heat-to-work, and Faraday's law of induction.

    Inside the BWRX-300 with Dr. John Zino | "We're just boiling water!"

    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 pumps. Natural circulation cooling. And the same proven fuel the industry has relied on for decades.We talk about why tech companies like Meta, Microsoft, and Google are suddenly interested in nuclear, how old coal sites are being converted for new reactors, and why the nuclear workforce could grow from 70,000 to half a million people in the next two decades.

    The 41-Hour Pour: When a Nuclear Plant Begins to Exist

    At 2:13 AM in Waynesboro, Georgia, crews were already deep into a process they couldn’t stop. For 41 continuous hours, concrete flowed into the basemat of Vogtle Unit 4, the foundation that would anchor one of the newest nuclear reactors in the United States. This episode breaks down: What a nuclear basemat actually isWhy concrete is part of the safety systemThe physics of heat, cracking, and radiation shieldingThe choreography required to keep a 41-hour pour aliveAnd why this moment marks the point where a power plant becomes real Watch: Vogtle Unit 4 Basemat Pour (Timelapse) If you only watch one thing, make it this.It’s the closest you’ll get to seeing thousands of people collectively refuse to mess up. https://www.youtube.com/watch?v=3UhwCOzqY5w&t=102s The basemat is a massive reinforced concrete foundation that supports: Reactor vesselContainment structurePrimary systems Once poured, there’s no going back. This is the “point of no return” in construction. Radiation shielding: absorbs gamma rays and slows neutronsStructural stability: supports extreme loads and seismic forcesContainment support: part of the safety barrier systemConcrete generates heat as it cures. Too hot, it weakensToo cold too fast, it cracks Mass pours require careful thermal control to avoid internal stress failures. Stopping mid-pour can create weak joints in the structure.

    Why Build Nuclear When We Have Solar?

    I Asked If Solar Could Power California… and It Got Complicated What started as a simple question turned into a full-blown debate:  If solar panels and batteries are getting so good…why does California still need nuclear energy? In this episode, we break down what actually keeps the lights on — beyond headlines, hot takes, and LinkedIn comment wars. What You’ll Learn Why “more solar” doesn’t automatically solve the problem Solar energy is powerful — but it only works when the sun is shining.Electricity systems need to work all the time, not just during ideal conditions. The difference between dispatchable and weather-dependent power Not all energy sources behave the same way. Dispatchable power = can be turned on whenever neededSolar & wind = depend on weather and time of dayThis distinction is at the heart of how power grids are designed. Why batteries help… but don’t solve everything Batteries can store energy for hours — not days or weeks. Scaling them to support an entire grid would require: massive infrastructurelarge amounts of materialsand systems we haven’t fully built yet The “last 10% problem” Getting to ~80–90% clean energy is achievable. But the final stretch to 100%? That’s where: costs rise sharplyreliability becomes harderand system complexity increases Capacity factor (explained simply) Not all energy sources produce power at the same rate over time. Nuclear: ~90% uptimeSolar: ~20–25% depending on locationThis affects how much infrastructure you need to meet demand. What is grid inertia? Power grids rely on physical stability — not just energy supply. Traditional plants (like nuclear and hydro): use large spinning turbineshelp stabilize frequency and flowSolar and batteries don’t naturally provide this, which means engineers must recreate it in other ways. Nuclear’s role in a clean energy system Nuclear isn’t replacing renewables. It provides: consistent, 24/7 powerhigh energy output from a small footprintstability for the grid when other sources fluctuate Special Thanks Thank you to everyone who contributed to the original discussion!

    Raised by the Reactor: How a 19 year-old Laborer Became a Nuclear Welder

    When people talk about building nuclear power plants, the conversation usually centers on policy, engineering, and billion-dollar infrastructure. But reactors aren’t built in conference rooms. They’re built by craft workers. In this episode of Naked Nuclear, Danielle sits down with nuclear welder Tyree McCall, who started his career at Plant Vogtle Units 3 & 4 at just nineteen years old. What began as a labor job quickly turned into a mentorship-driven apprenticeship where experienced workers pushed him to level up his skills and pursue welding. Working ten-hour days and attending welding school at night, Tyree eventually transitioned into nuclear welding—one of the most technically demanding and responsibility-heavy crafts in the industry. Together, they explore what it really takes to build nuclear infrastructure: discipline, safety culture, accountability, and the personal growth required to succeed in a high-stakes environment. This episode pulls back the curtain on the boots-on-the-ground workforce that makes nuclear energy possible. How Tyree landed his first job at Plant Vogtle Units 3 & 4 What it feels like to walk onto a nuclear construction site at 19 Why the mentors on site “raised him” in the craft The reality of working full-time while attending welding school at night The difference between nuclear welding and other welding careers What nuclear safety culture actually looks like on a job site The intense pressure of passing nuclear welding certification tests How failures and feedback shape skilled trades professionals The lifestyle changes that come with holding a nuclear badge and clearance Advice for students considering trades careers in the nuclear industry Tyree credits much of his early success to experienced workers on the Vogtle site who encouraged him to pursue higher-skilled trades and pushed him to think long-term about his career.
