      Hello, Tyler! Good video you got here. I love Plainly Difficult, they're an excellent channel.
      I'm here to drop another suggestion for you, have you seen the TV series: "For All Mankind"?
      There's a really cool scene at the start of season 2 where a significant CME from our sun impacts a lunar base - and there are some cool little quirks related to radiation that you could dive into. And it's overall just a really cool scene. Would love to see you react to it. It's the first episode of season 2. There's a few scenes on YT, but it would be much greater to see the actual episode!

You really want to do his series about the Chernobyl accident as well. They're quite long (especially the last 2 out of the 3), but very well researched and done. I'm sure you'll appreciate them. TMI is another you may want to watch from him.

Hearing about "the control rod going critical" was a new one for me, too. Never knew these could do that^^. And the "critical" when someone means "prompt critical" is one of those that keep tripping people up as well.

    Plainly Difficult's nuclear videos and orphan sources ones are great.
    He even has one that very few have covered, where the source got melted down and mixed with the steel, then sold as rebar.
    How did we find out about it? A truck carrying the rebar took a wrong turn and used a nuclear facility as a turn around spot, making their radiation detectors go haywire when the truck drove through.

    SL-1 is actually about 50 miles west of Idaho Falls in an area known now as the Idaho National Laboratory (known then as the National Reactor Testing Station). It was definitely not IN Idaho Falls. All of Idaho would probably be considered deserted by most urbanites (I grew up in Idaho Falls and have multiple family members that worked as engineers out at the site in the desert) but Idaho Falls itself is home to about 70,000 people. All the experimental stuff is done far away from them.

  • @trinalgalaxy5943
    @trinalgalaxy5943 9 месяцев назад +3

    one thing to note about SL-1s design is that the control rod was designed to be operated using a crane in the roof of the building. the problem was that during maintenance, the control rod was disconnected from the crane hence the restart procedure required lifting the control rod 10cm with their own hands to reconnect the rod to the crane. add in the stickyness of the rods, the surprising thing is that it took that long before something happened.

    Throughout this video you keep mentioning that today a lot of these things would not be possible (manual movement of control rods, excessive control rod speed, a single fully extracted rod not being capable of causing criticality, etc.) All of those safety items can probably be directly attributed to the lessons learned in this accident.

  • @Justin_Ebright
    @Justin_Ebright 9 месяцев назад +2

    For anyone wondering, prompt critical is when a source reacts upon itself. Delayed critical is when it's controlled with items like boron 10. So, think of it like this; Prompt is the same as nuclear bombs minus the explosive construction to keep the reaction contained till explosion. Delayed is what's used in reactors, etc.
    Another topic I'd like to broach personally is the misunderstanding around half-life. Just because a material has reached its half-life it doesn't mean it's safe by any means. It just means literally half has be used. But if something is 10000x deadly, half is still 5000x deadly. I've seen too many people playing around with cobalt-60 from medical equipment because it's 5-10 years old as if its safe meanwhile their photos are full of artifacting.

    While I do love John's videos, I do think that Kyle Hill's version was better - it told a lot more about the dynamics between the 3 operators, and what was happening to them. This was a disaster waiting to happen - the central conrol rod was only supposed to have been lifted a few inches to reconnect it to the drive mechanism, but these cruciform 'blades' tended to get stuck - regardless of whether it was an accident or deliberate that it was lifted too far, having only one rod causing the reactor to go 'prompt critical' was surely a massive design error!

    Plainly Difficult specializes in industrial disasters, and gives good historical background for context (for instance, a history of poor maintenance or problems with a design at other sites). He also breaks down the chain of dumb choices, mistakes, and low-grade malice that leads to the specific result.
    Whether it's nuclear, oil-refining, or big civil engineering projects like bridges and dams, he's very good at showing how "accidents" don't just randomly happen, and why single-point-of-failure designs are just BAD.
    His delivery is less dramatic than Kyles, but I wouldn't mistake it for lack of sympathy for the people affected by the incidents.

    I've seen several of your videos, and feel you may not understand the reason for lead lined coffins. It is not for blocking radiation. It's for maintaining containment of contaminated remains.
    Lead prevents moisture, plants, animals, and in some cases, people from getting into the coffin, while also preventing decomposition and leakage into immediately surrounding soil.
    These graves are usually in regular grave yards. The surrounding soil may be disturbed for any number of reasons, including possible relocation of remains. Having a reliable container is an important precaution to prevent someone getting an unintended dose down the line.

    It's worth pointing out, about the "this kind of thing can happen; one person can be working for you and years later, you be working for them" bit, these men were Enlisted personnel in the _Military._
    If you were passed up in favor of a peer for some reason or another, you are *_incredibly_* unlikely to play the Tortoise to their Hare and catch them up and surpass them. Generally it requires that _they_ perform what the Brits so charmingly refer to as a 'Career-Limiting Maneuver' later-on. (All of the American terms are vulgar.)
    Also, it's been a hot [particle] minute since I looked at this incident, but I don't think *_any_* of these men _wanted_ to be nuclear reactor technicians; they were _ordered_ to do it. There's a reason Navy Nukes nowadays can _pretty much_ get away with ignoring virtually all military bearing, personal fitness and hygiene, etc; because anyone who _willingly_ does the work, for an Enlisted person's wages, is absolutely mission-critical and can get away with anything up to and including *_physically ejecting_* an _Admiral_ from a nuclear controlled area of the boat.

    For heaven's sake, the guy wasn't impaled by a 'shield plug'. It was the upper part of the control rod itself. The rod in the core had a long shaft running up through the head of the vessel, the shielding, and would normally be attached to the drive mechanism that raised/ lowered the rod.

  • @TAKIZAWAYAMASHITA
    @TAKIZAWAYAMASHITA 9 месяцев назад

    With all the theories I'd say the accident was a combination of them. The operator having issues with a wife divorce at home plus the already known issue of control rods sticking meant he wasn't paying close attention to how far he was moving it plus likely used too much strength and just yanked it out expecting it to be stuck when it wasn't.

    This story in particular has always fascinated me, as I did my last bit of training in the Navy's nuclear program at the INEL site outside of Idaho Falls. We drove past it every day in the winter of 1989, before RUclips videos and Wikipedia. All we had were stories from old staff members about how the Army managed to make a reactor go prompt critical BY HAND, killing three people in the process, and that's why only the Navy gets to play with nuclear reactors now.😁
    Add me to the chorus of voices recommending Plainly Difficult's videos; he has covered some very interesting criticality events and orphan sources that I had never heard about (and I'm a bit of a nuclear history buff).

    Quick comment regarding the handling of the bodies: Yes, the bodies were severely contaminated, but due to the extremely high and dense neutron flux exposure, they were also activated themselves. Between the contamination and activated portions of their bodies, the radiation given off was on the order of 100-400mRem/hr at 1ft even after removal of clothing and initial decontamination.

  • @bobmilburn5296
    @bobmilburn5296 9 месяцев назад

    I would like to point out that the control rod in question was not hand-controlled. The reactor was being restarted and this required the control rod to be re-connected to its motor drive. This was the reason the rod had to be lifted slightly.
    I recently spoke with an elderly nuclear engineer who was at the proving grounds when this happened. I asked him what actually happened at SL-1 and he immediately replied "murder/suicide".
    You can watch video of the re-creation of the accident by investigators. They determined that an adult man could withdraw the rod by himself, but it required a great deal of effort. Accident seems less likely to me.

    I don't normally look at 'reaction' style content, but somebody had brought the original video up to me again, and I saw your video. I thought the following needed to be said:
    I'm almost certain Plainly Difficult's script is just a summary of the SL-1 Wikipedia article. I've since fixed the error in the original, but he perpetuated the incorrect information that the National Reactor Testing Station, and thus the accident site itself, was *in* Idaho Falls. His next claim is that the area is "pretty isolated." This would make sense if he had mentioned the real location, but Idaho Falls had somewhere between 19,000 and 33,000 people. (There's a ten year gap in census data here, and this was a HUGE growth period for the city.) There's a some other little bits missing and or incorrect, but that one slapped me in the face when first watched the video.
    I don't mean to be too negative, but this sort of thing is a pet peeve of mine. It's especially frustrating because you can see him using satellite imagery of the reactor burial site. I'm disappointed he didn't realize the mistake at this point, as I'm sure he would have seen Idaho Falls from the sky.

    I have a question about the boron used to stop the reaction. So fission occurs when free neutrons interact with the uranium and when you lower the boron control rods then the boron absorbs the free neutrons, starving the reaction, right? So can the boron be satisfied to the point where it can no longer absorb neutrons? If so, what happens to them when they reach that point? And if not, why can't they be satisfied?
    PS: If this question is dumb, I apologize but I know absolutely nothing about nuclear reactors and their functionings as I am still really new to your channel

    • @mobiuscoreindustries
      @mobiuscoreindustries 9 месяцев назад +1

      In a way it is technically correct, you could burn the boron through tremendous effort in the same way you can burn Xenon, however boron being often either in liquid or solid form (well a doped material but still) it's density is much, much higher. There is therefore far more of it to sate. Though over time the boron concentration of the rod is going to lower which is why control rods have a fixed life span. Just like with fuel rods, their effectiveness is monitored and they are swapped out when no longer effective.
      The amount of radiation needed to fully disable a rod however would imply you have a far more pressing problem in any case. Because the kind of energy released would have detonated the core nanoseconds into the excursion..

I am not a nuclear engineer, but even I can see that's really bad idea. Today no nuclear reactor in operation have these problems :p

    I read the official account of this. It included many different individual testimonies regarding the process.
    By the end of it, it was pretty clear what happened. The intent was to use a lifting mechanism on the rod. They had disconnected the rod from the lifting mechanism and the rod had settled down past the point where the lift mechanism could be attached.
    Easy right? Just grab the end of the thing and lift it up to the point where it could be attached to the lifting mechanism.
    Well...
    Whoopsie. It was stuck just enough that when he pulled on it.. it came too high up.
    There are even telltales on the rod where they say they can even see how far he got it back down before it blasted him. About 3/4 of an inch.
    So yeah... this was most likely accidental. They actually know a LOT more than what is in this video.

I know the different language can be a problem but I really think it's worth watching it. Shows a LOT of stuff that for sure you know.

      @@Aztesticals We do! But it's a really touchy subject. The technology came from Germany and France and the agreement was a little shady... Take it with a grain of salt because I have only studied it to get into university so I mostly studied the political angle of it... Brazil has many sources of energy but we rely heavily on hydroelectricity. Going nuclear was far more political than practical. Not that it's bad, but we basically signed agreements "trading" technology to make propaganda on top of it, since until this day we basically didn't finish them. Political stunt made by the military in power. If we actually make it work it's gonna be wonderful... Building hydroelectric power plants DESTROYS a lot of things.

    22:14 i mean you could also have just put like a little nub on the side of the rod and like a lock on the reactor roof so that you physically couldn't move it more than 50 cm without first unlocking that little latch that would also have prevented this also you could make the control rods wedged or cone shaped so that the couldn't come that far out without out first removing the fuel assembly around them first there by making this impossable

    Yeah, this is the classic accident we all studied. It is the direct cause of the 'cold-stuck-rod' criteria. No reactor design today can go critical with even the most reactive control rod fully removed. Obviously, this reactor with only 5 rods did not meet that criteria.

    Kyle Hill also discusses the suicide theory, primarily based on the affair that one of the men had with one of the other men's wives. The wife had apparently asked for a divorce and there was allegedly a conversation between the man and his wife shortly before he started his shift that night. Seems far fetched, but people do crazy things.

    Another good channel is the "USCSB" US Chemical Safety Bureau. They do for the chemical industry what the NTSB does for transportation (Investigate and provide suggestions but have no power to enforce, so they arent corrupted by power) The video "Iron in the fire" by them is as good as a starting point as any. Nothing nuclear, but plant safety/industrial process safety should be adjacent enough for you to have at least some parallels.

    I'm not sure the correct phrasing should be - the reactor shut itself down quickly after the accident, as there was no reactor left haha. Hard to maintain criticality in the event of sudden self-disassembly.
    And while I imagine the effect is minimal, you could become radioactive by inducing radioactivity in the sodium, potassium, and I think lithium? in your body.
