Standard once-through nuclear reactors burn only roughly 5% of their uranium fuel, treating the remaining 95% as waste. Transitioning to fast-spectrum reactors that recycle used nuclear fuel can extract 60 to 100 times more energy, expanding known uranium reserves from roughly 120 years to 12,000 years of civilization-scale power.

Conventional reactors use only 5% of their fuel. Oklo's technology recycles the remaining 95%, transforming the nation's nuclear "waste"—a massive liability—into an energy asset with more potential energy than Saudi Arabia's oil reserves.

Breeder reactors, which can create more fuel than they consume, are the key to a multi-billion-year energy supply. However, they are currently more expensive than conventional designs. The transition to a breeder economy will be driven by a future economic crossover point when recycling 'waste' fuel becomes cheaper than mining new uranium.

The process of nuclear fission is a form of alchemy, transforming uranium into a wide array of other elements. Recycling facilities can separate and harvest these materials, turning "nuclear waste" into one of the world's richest sources of valuable and critical minerals.

While new Small Modular Reactors (SMRs) won't produce energy until ~2032, GE Vernova's CEO says a faster path to more nuclear power is upgrading America's 56 existing plants. This modernization effort alone can add five gigawatts of capacity to the grid.

To meet massive future energy needs, the only scalable solution is building large, proven nuclear reactors like Westinghouse's AP1000. Small modular reactors (SMRs) are largely unproven "science experiments" and cannot scale quickly enough to address the impending deficit.

Public fear of nuclear waste is a significant barrier to adoption, yet it's largely a perception issue. Technologically, 'spent' fuel rods contain 95% of their original energy potential, primarily as U-238. Breeder reactors can utilize this 'waste' as fuel, dramatically expanding energy supply and reducing the final waste volume to a fraction of its current size.

TerraPower's advanced nuclear reactor design can use depleted uranium—currently treated as waste—as fuel. The amount of this material already stored in a single U.S. facility is sufficient to meet the entire planet's energy needs, carbon-free, for hundreds of years.

Spent nuclear fuel consists of solid ceramic material contained in metal rods within engineered casks, occupying a footprint that could fit on a single football field. Unlike fossil fuel operations that exhaust carbon dioxide into the open atmosphere, nuclear byproducts are completely contained, concentrated, and chemically reusable.

TerraPower's breeder reactor simplifies a complex process by functioning like a candle. An initial reaction "melts" the abundant U-238 fuel, making it usable. This allows the reactor to continuously prepare its own fuel as it runs, just as a candle wick draws up melted wax.

Conventional water-cooled reactors can't reach the high temperatures needed for industrial processes like steel and concrete production. Advanced reactors using coolants like sodium can operate at 500-800°C, unlocking the ability to decarbonize the massive industrial process heat market, which accounts for nearly a quarter of global energy consumption.
