HALEU & Hubris: Oklo vs. Centrus

They call it the future. Nuclear, that is. Oklo and Centrus Energy, two outfits playing footsie with high-assay, low-enriched uranium – HALEU, for those keeping score. A joint venture, they say. More like a carefully constructed dance around a shrinking pool of capital. The kind of thing that looks good on a press release, but feels like a bad bet in a smoky back room.

Both companies are angling for a piece of the expanding nuclear pie, but one’s built on vapor and promises, the other on a slightly less shaky foundation of existing business. It’s a difference between a gambler’s flush and a working man’s pair. And in this game, I favor the man with the cards he can actually see.

Oklo’s Reactor Dreams

Oklo’s building miniature power plants – Aurora powerhouses, they call them. Liquid-metal cooled, based on some old tech from the Idaho National Laboratory. Sounds impressive. It’s also a long way from actually generating juice. They’ve got Meta – Facebook, to those of us who haven’t completely abandoned reality – pre-paying for power in Ohio. A billion-dollar IOU for a project that won’t see the light of day until 2030, maybe. It’s the kind of deal that keeps lawyers employed and investors anxious.

Their reactors need this HALEU, this “premium fuel.” And that’s where Centrus comes in. They’re the only ones with an NRC stamp of approval to enrich it up to 20%. A monopoly, in the nicest possible way. It’s a comfortable position, like owning the only bar in a ghost town.

Centrus currently peddles the regular stuff, LEU, to existing plants. But their supplier, TENEX, is Russian. A complication, to say the least. A new law is coming down the pike, cutting them off in 2028. So Centrus is trying to build a domestic enrichment facility in Ohio. A $900 million gamble, courtesy of the Department of Energy. It’s the kind of thing that happens when politicians discover a problem and throw money at it, hoping it goes away.

Which Reactor Gets Your Dime?

Oklo is all potential, a mirage shimmering in the desert. Centrus is…less so. They’re already profitable, selling fuel to plants that actually exist. Oklo’s first reactor won’t be operational until late 2027, assuming they can navigate the usual bureaucratic quicksand. Delays are practically guaranteed. It’s the nature of the beast.

Both companies will benefit from the nuclear revival, if you can call it that. But Oklo is years away from turning a profit, a distant promise in a world demanding results now. Centrus has its own challenges, expanding the Ohio facility will cost a fortune. But they have a business, a revenue stream, something tangible. It’s the difference between a blueprint and a building.

In this game, I’ll take the company that’s already counting the money. The future is always uncertain, but a solid present is a good place to start. And in the world of high finance, a bird in the hand is worth two in the reactor.
