The Secret Effort To Clean Up a Former Soviet Nuclear Test Site

Posted by Soulskill on from the head-down-to-the-plutonium-dump-and-grab-me-something-shiny dept.

Lasrick writes "The Plutonium Mountain report has just been released by the Belfer Center at Harvard. It describes the remarkable effort the U.S. made to get the Russians to recognize the nuclear proliferation risk they left behind at the Semipalatinsk Nuclear Test when the Soviet Union collapsed. In this interview with Siegfried Hecker, he describes how he and other scientists at the Los Alamos National Laboratory recognized the risk to world security as the Semipalatinsk site became overrun with metal scavengers. Quoting: 'The copper cable thieves were not nomads on camelback, but instead they employed industrial excavation machinery and left kilometers of deep trenches digging out everything they could sell. We were concerned that some of that copper cabling could lead to plutonium residues.'"

    Reading the summary I thought "No big deal, so some contaminated dirt is out there and someone might refine it for a few grams of plutonium residue."

    But then I decided to read the article. It was slashdotted of course so I went on Google and found the article at a non-slashdotted site. (I know, not really the slashdot way.) All I can say is, HOLY PLUTONIUM Batman! Not residue from tests, but hundreds of pounds of plutonium metal in useable form. Enough for dozens of nuclear bombs. And they capped it and left it there! And now they are telling the world where it is. I'm speechless. (Other than the preceding text of course.)

      One of the most difficult problems with nuclear materials production is removing the desired materials (fissionable) from the undesired ones. So having hundreds of pounds of plutonium may not be nearly as big of a deal as you might think, if it is mixed in with thousands of pounds of other materials. "Dirty bomb(s)" might have been producible from the materials on the site, but actually construction nuclear weapons seems unlikely without a monumental undertaking.

      No. This was unburnt fissile material - U235 and/or Pu239 - from nuclear tests, conveniently buried underground. The hard work (enrichment of U235 or making sure that there was no pesky Pu240 in the mix) had been done by Soviet weaponeers. Extracting that material from an atomic test site is nontrivial, but a hell of a lot easier than producing it from scratch.

      The unstated assumption was that atomic test sites, being some of the most secure sites in any country, would remain secure. That assumption failed when the USSR broke up, and these sites became map locations in a real-life game of Fallout: former top-secret military bases left unguarded and chock-full of with loot for any intrepid, foolish, or batshiat crazy explorer to poke around in. 99% bottlecaps (copper wire), 0.99% deathtraps (hello, cancer!), and 0.01% game-altering resources for well-equipped villains with nefarious intent.

      The awesome thing about this story is that weaponeers from both sides of the Cold War, deeply conscious of the need for each side to preserve its secrets (samples of melted glass from the inside of an underground Soviet test site would still be an intelligence bonanza for the US), managed to find a way to come together and secure the site without compromising each other's secrets. Good on ya, guys. And thanks.

      I don't get how 50 gallons of nearly dry Strontium at the bottom of an annulus (that's the empty space between two tanks) with cameras watching it is anywhere near "almost as bad" as the tens or hundred of kilograms of plutonium spread across the equivalent of small European country, but whatever. People forget they're paying a bill for an arms race and the legacy of cleaning up from a hastily engineered atom bomb in WWII and subsequent Cold War ain't cheap! To the tune of BILLIONS of dollars actually. Russians have been (and continue to visit and help) at Hanford. That was part of the article about building trust. I've visited with them before...bright folks with some incredible experience and wisdom.

    A Democrat and a Republican saw a genuine national security threat and agreed on a way of combating it without macho bullshit. They pushed their solution through even though it involved the unpalatable idea of sending money to a former enemy full of people certain to steal it. As this story shows, it worked.
