For twenty years, about one in three US nuclear reactors ran on fuel that used to be Soviet warheads.

That is not a metaphor and it is not a rounding-up of something smaller. The US Energy Information Administration puts a specific number on it: between 1993 and 2013, a program marketed as Megatons to Megawatts "converted 475.2 metric tons of highly enriched uranium into 13,723 metric tons of low-enriched uranium," and that low-enriched material supplied "about one-third of the enrichment services needed to fabricate fuel for U.S. nuclear reactors" across the whole two decades. The highly enriched uranium came out of dismantled Russian bombs. Blended down, it became the thing that spun the turbines.

I went looking for how the weapons material actually moved, because a claim that clean usually hides a messier reality underneath. It does.

One of the tributaries feeding that pipeline was Project Sapphire, a covert November 1994 operation to pull weapons-grade uranium out of the Ulba Metallurgical Plant in Kazakhstan before anyone else could buy it. The declassified after-action report — Defense Threat Reduction Agency, released through the National Security Archive — is the least sanded-down piece of official Cold War history I have read in a while. It records that the funding "was obtained through DOE the day before the OSIA team departed." It records that "OPSEC was a grave concern... classified technical conversations occurred at the hotel, within earshot of foreign nationals." A hostile plant employee reportedly walked team members into a room with an active metal fire.

So: an improvised airlift, funded the day before it left, feeding a downblending pipeline that would go on to underwrite a third of American reactor fuel. That is already a good story. It is not the story I want to tell.

The story is what the deal did to the company running it.

The material was cheap. That was the entire point — Megatons to Megawatts worked because blended-down warhead uranium was cheaper than enriching fresh uranium from scratch. Cheap disarmament is the only kind that scales. But the US executive agent selling that cheap Russian material into the American market, a company called USEC, was also, at the same time, trying to build a brand-new domestic enrichment plant of its own: the American Centrifuge project. One company, two jobs. Import the cheap thing. Build the expensive thing.

You can see the collision coming. USEC filed for Chapter 11 in 2014 and reorganized as Centrus Energy. The American Centrifuge project did not survive contact with the economics.

I want to be precise about the causation, because this is the leg I can't fully nail down. The tidy version — the cheap imports strangled the domestic project in its crib — is the version that makes the best headline, and it is exactly the version my sources do not quite state. The World Nuclear Association's account leans the other way: it emphasizes that the end of the downblended-weapons supply, when the twenty-year deal closed on schedule in 2013, is what hurt USEC. The American Centrifuge project also had its own cost overruns, independent of anything Russian.

But sit with the WNA version for a second, because it is somehow more damning than the tidy one. A company whose entire business was reselling Russian warhead uranium went bankrupt the year after the Russian warhead uranium stopped arriving. The disarmament deal succeeded so completely, and for so long, that its administrator forgot how to exist without it. Either way you weight it — killed by the cheap supply or killed by the supply ending — the same fact is doing the damage. USEC lived and died by the same material. The cheapness that made the nonproliferation work is the cheapness that made a domestic industry impossible to justify while it lasted, and the dependency that cheapness created is what broke when it stopped.

The cheapness did both jobs.

Here is where it stops being history. That domestic enrichment capacity — the thing the deal hollowed out — is now being rebuilt on purpose. A 2024 US law banned Russian low-enriched uranium imports, with waivers running through 2028. Centrus, the reorganized ghost of USEC, holds Department of Energy contracts framed, in its own words, as an effort to "restore America's ability to enrich uranium." The country spent the 1990s and 2000s letting a domestic industry lapse because Soviet bombs made fuel too cheap to bother, and it is now spending real money to grow that industry back.

And the demand is climbing at exactly the wrong moment to be short on domestic fuel. US utilities are restarting shuttered reactors to feed AI data centers — Three Mile Island Unit 1, of all sites, is being brought back as the Crane Clean Energy Center under a twenty-year Microsoft power purchase agreement, targeting 835 megawatts by 2028. Inference runs continuously, so the compute translates into baseload electricity, and baseload electricity wants reactor fuel. The question "where does US reactor fuel come from" has been geopolitically loaded since the Kazakh airlift. It is about to get louder.

I don't have the clean causal chain from cheap imports to bankruptcy, and I'm not going to pretend I do — that is the next thing to chase, into the actual bankruptcy filings rather than the trade-press summaries. But the shape holds without it. A weapon becomes a fuel. The fuel becomes cheap. The cheapness disarms a country and undercuts an industry with the same stroke, and thirty years later that country is paying to rebuild what the disarmament made uneconomic, just as it needs the fuel most.
