Last Fall a Drone Swarm Surveilled America's Largest Nuclear Reactor -- Twice (forbes.com) 114

America's Nuclear Regulatory Commission honored a document request from a UFO group — which has inadvertently revealed a very real incident last fall at America's largest nuclear reactor in Arizona, reports Forbes: Documents gained under the Freedom of Information Act show how a number of small drones flew around a restricted area at Palo Verde Nuclear Power Plant on two successive nights last September. Security forces watched, but were apparently helpless to act as the drones carried out their incursions before disappearing into the night. Details of the event gives some clues as to just what they were doing, but who sent them remains a mystery...

"Officer noticed several drones (5 or 6) flying over the site. The drones are circling the 3 unit site inside and outside the Protected Area. The drones have flashing red and white lights and are estimated to be 200 to 300 feet above the site. It was reported the drones had spotlights on while approaching the site that they turned off when they entered the Security Owner Controlled Area..."

The drones departed at 22:30, eighty minutes after they were first spotted. The security officers estimated that they were over two feet in diameter. This indicates that they were not simply consumer drones like the popular DJI Phantom, which have a flight endurance of about half an hour and is about a foot across, but something larger and more capable. The Lockheed Martin Indago, a military-grade quadcopter recently sold to the Swiss Army, has a flight endurance of about seventy minutes and is more than two feet across. At several thousand dollars apiece minimum, these are far less expendable than consumer drones costing a few hundred. All of which suggests this was not just a prank.

The next night events were repeated...

The article notes that two months later America's Nuclear Regulatory Commission "decided not to require drone defenses at nuclear plants, asserting that small drones could not damage a reactor or steal nuclear material. It is highly likely that such sites are still vulnerable to drone overflights."

The article also notes that this reactor supplies electricity to major American cities including Los Angeles, San Diego, Phoenix, and Tucson.

    ... but I imagine a kilo or so of some military grade explosive could cause a bit of a problem, good job drones can't carry stuff!

    • Well, big aircraft fly over or close by these sites all the time. A Boeing 737 crashing onto it is a more serious possibility.

        FAA has issued a NOTAM (FDC 1/1763) prohibiting all General Aviation flights within a 10 nautical mile radius and below 18,000 feet of 86 nuclear sites throughout the United States.

    • Maybe sniffing electronic signals at very specific locations to verify brand and make of equipment would be enough intelligence to engineer an electronic attack?

      The thing they excel at is transmitting information. If you wanted to storm the reactor and overwhelm the security forces, a drone could give you information that an aerial photo couldn't.

    • Honestly, no, it can't.

      I mean sure, it could kill someone, or blow up a control console, or shatter some windows, break some (trivial) piping/wiring...but contrary to Hollywood, laying C4 atop something - particularly something even slightly hard like steel - ends up doing little more than scorching/denting it.

      While I certainly would be concerned about people gathering intel on such sites uninvestigated, the idea that a small drone even carrying explosives could do any meaningful damage is largely true. Th

      • The smallest bomb in the US inventory weighs 285 pounds. It's used to hit things like fuel tanks.

        The UAV mentioned in the summary, costing "several thousand dollars each, minimum" has a maximum payload of 5 pounds, or 2 kilograms.

        The large consumer-grade fireworks are 2.2 pounds, 1 kilogram. You'll see them labeled as "500 gram class" because it's assumed that 1kg total weight is 500 grams of cardboard + 500 grams of explosive.

        The maximum payload of these UAVs would be twice the size of a fireworks stand

        • I should mention, the RDX explosive used by the military has 2-3X higher "relative effectiveness factor", or TNT equivalent, than fireworks explosive does.

          Still, FEMA says 20 pounds of TNT (a 40 pound bomb) will break glass windows up to 40 feet away. A five pound bomb? It might break glass 5 feet away or so. Fortunately, nuclear reactor containment buildings aren't made of 1/4" glass.

    Sure. And they're still vulnerable to people standing on a nearby building with a camera. So what? Nuke plants aren't some top secret project which we need to protect from spies. Most of them are 1960s technology; not exactly high-tech shit for foreigners to steal.

      Or any normal conventional weaponary from the same decades as the facility. You can probably get quite a few RPGs for the price of that drone and take a few shots from 1/2 a km. Yeah, people need to stop seeing so many movies. You are not going to decimate a nuclear facility with even a tank or 1-2 missiles from a jet. Damage it, sure.

      For the US, the biggest return for a terrorist would be the public fear and political noise... both would cause more disruption to society well after the site was fixed up

      Where are there buildings nearby nuke plants which are tall enough to get the equivalent of aerial reconnaissance photos?

    The drones have flashing red and white lights and are estimated to be 200 to 300 feet above the site.

    If you were trying to be stealthy, you should probably disable those first.

    • by Viol8 ( 599362 )

      Hard to be stealthy anyway with the amount of noise the propellors on drones make.

      • Hard to be stealthy anyway with the amount of noise the propellors on drones make.

        For consumer garbage yes, but fancy expensive drones used for surveillance, military, and film production are pretty damn quiet. e.g. the one linked in TFS is advertised as undetectable at 300ft.

        • Every drone is undetectable at similar distances.

          Look, any time you have a vehicle held aloft by propellers, it's going to be fucking loud. That's just physics. This is why everyone laughed at the "stealth helicopters" which were used to kill Bin Laden. The difference being that the "stealth" on those helicopters was meant to fool radar, and not people on the ground hearing them roar overhead. There are certainly things you can do to make them slightly less loud, but nothing you do is ever going to make

            Ahhh I forgot, every drone sounds completely the same and has 100% identical noise signature.

            For those of you who don't understand decibels no, given the volume and distances involved even having a dB or two difference in noise at will wildly change what at what distance a drone is detectable.

            • by Entrope ( 68843 )

              A 12% increase in distance causes a 1 dB drop in volume. Is that a wild change? How does it compare to the listener's angle relative to the body of the drone?

            • Ahhh I forgot, every drone sounds completely the same and has 100% identical noise signature.

              Nah, you didn't forget, you're just being a disingenuous cunt by ignoring the fact that I used the word "similar".

              Yes, "wildly" as in "my drone is now only detectable at 300 feet instead of 350!". Big fucking whoop. As if we don't have lenses which can make the extra 50 feet completely irrelevant.

                It sounds like you just like to make baseless comments as facts and then get mad when someone corrects them. 50 foot can make a HUGE difference. 99% of drones do not have zoom lenses. Zooming with a fixed lens requires moving closer or further away. 50 foot can dramatically raise the noise level! (Again, I fly drones and have actual experience here.)

          • Stealthy helicopters are not quiet if you're standing underneath them. But they are quiet if they're behind a hill. Given that existing attack helicopters carry missiles large enough to kill a tank with a single hit (Hellfires) that's still pretty stealthy. Especially since Hellfires can home on a target that someone else has designated... They can "pop" up over the hill, launch a missile, and drop back below it before anyone has even figured out where it is.

            Drones, on the other hand, don't have to gain all

            Not true. I have flown and owned several drones, including building one from scratch. I can 100% debunk this claim. A DJI phantom 3 at 400 feet can easily be heard on an average day. They are very noisy. The Inspire drones made for filming are far quieter at 400 feet and you'd really need to be paying attention to hear it.

      If you've got multiple people flying the drones in formation, which is the only way I can imagine accurately handling six drones at once, those drones should probably be able to see each other. Turning off the spotlights makes it harder for a guard on the ground to pinpoint the individual drones with a firearm but make it clear to the other drone handlers through cameras where not to fly.

        It occurs to me that a set of six drones could maintain a formation by using some kind of laser system to network the drones together so they know where each other are. If you have only two drones, this won't help much with maintaining distancing between drones. If you have three or more and can measure the relative angles, you could maintain a decent enough formation. But that leaves the question of why you would want to fly a flight of these things in formation in the first place. About the only reason I

    I wonder what they base their estimate of the drone size on? Estimating the size of an object in the air is notoriously hard.

    If the distance estimate of '200 or 300 feet' is accurate, that would leave the possible range of sizes for the drone pretty wide.

  • Obviously a U.S. government agency was flying those drones. They had their lights on. The Lockheed drone is "...invisible above 300 feet," yet they flew at or below that height and had their running lights on. Also the NRC concluded nothing should be done. Of course.

    IF this wasn't just a prank, then I'd say what the drones were doing was reconnaisance. By whom and for what purpose? Who the hell knows.
    Considering all the shit going on in the world and in this country, the possibilities don't make me feel very warm and fuzzy.
    Of course the purpose could be precisely the above: scare tactic, make us think someone is planning an attack of some sort on that reactor facility. Otherwise why repeat it the next night? Make sure the drones were seen and reported.
    Another possibility, less likely: proof-of-concept of some sort.
    • ..oh and by the way: why the actual FUCK didn't security personnel at that facility try to shoot one down?
      • Your prior post was very good. This one was ridiculous. Shooting targets overhead is very difficult at the best of times. At that range you have very little hope of hitting a moving target with a pistol, a rifle would be too dangerous (what goes up...) And if the guards have shotguns, they're not choked for range.

        • It was just a thought that I'm sure some security supervisor on-site must have had, regardless of there being a practical way to do it.
      • What are they going to do? Run and get a shotgun and try to plink one flying at 300ft? You'd require multiple hits of birdshot to even make the drone notice.
        • Dunno. It was just a thought. I'm sure some supervisor-type person on-site at least thought to themselves "..isn't there some way we can take these down?"
      • Your best bet would be to fire up a GPS jammer and hope the drone falls back to "hover" mode. Unfortunately jammers are highly illegal but being illegal never stopped Uncle Sam from doing anything.

        • After all this time that drones of that sort have been around I'd think that someone would have come up with some way to take them down just for situations like this where they're encroaching on restricted airspace like a nuclear power plant.
  • A few notes: DJI drones don't fly for an hour. You'd be ecstatic if you got 30 minutes. DJI drones cost more than a few hundred dollars. Lastly, why did they have lights AND a spot light? That doesn't seem very covert.
  • No, I seriously doubt that drones can directly hurt the reactor. However, they can attack the outdoor exposed cooling piping, thereby disconnecting cooling. Likewise, they can attack the grid connection dropping electricity. With only 100 plants, providing 20% of America's electricity, that would be an easy/cheap way for china to bring down for several days, while they invade Taiwan. Or, AQ, or Antifa, or just some far left anti-science extremists that wants all nuke plants gone.

    200 to 300 feet is well within the range of 12 gauge magnum loads. the security already have submachine guns, why not add semi-auto shotguns to what they carry. Use searchlights for night. And for those wondering, the shot return to earth at a very small fraction of muzzle velocity, only annoying not injuring.

  • If there's one thing I've learned, it's that the enemy will _never_, _ever_ do shit you didn't think about and cause massive damage. Where did I learn this? 9/11.

    Can you imagine being a time traveler trying to convince these morons what would happen that morning?
