  • here is another crazy incident:

    "Around 10:30 p.m., the supervisor for the contractor running the site (Combustion Engineering) and the chief health physicist arrived. They entered the reactor building and found two mutilated men soaked with water: one clearly dead (Byrnes), the other moving slightly (McKinley) and moaning. With one entry per person and a 1 minute limit, a team of 5 men with stretchers recovered the operator who was still breathing; he did not regain consciousness and di More..

    • @keen
      Thats a one-in-a-lifetime experience: Standing somewhere above the reactor, lifting the rod just a little too far and just BAM that huge vessel jumps and you find yourself pinned to the ceiling left to die.... pretty horrific

    • @keen Holy shit I've heard about this incident but never knew they were kicking out 500 R an hour. That's enough to kill a person just standing next to the body for an hour. Incredible.

    • @keen Interesting quote from that article: "In the accident, the core power level reached nearly 20 GW in just four milliseconds..."

      Holy crap. This thing could have powered about 16 of Doc Brown's flux capacitors...

  • Just imagine how much radiation we are getting from the open air criticalities caused by the MULTI nuclear reactor meltdowns in Fukushima Japan. The disasterous radioactive emissions via air, land, and sea will continue from the 2011 meltdowns for THOUSANDS OF YEARS.

    Educate yourselves; your lives and the lives of your posterity HAVE ALREADY been shortened and/or mutated by this event.

  • Fascinating... and hard to believe that this had to happen, for only after this incident they started using remote controlled machinery.

  • "Tickling the Dragon's Tail" was also done by dropping a slug of uranium through a subcritical assembly. Extremely dangerous and these guys knew it.

    Slotin allegedly received about 2100 REM (or 21 Sv) during this tragedy.

    450 REM is taken as the dose necessary to kill 50 percent of the people exposed to it so he was fucked before he even separated the halves of the the beryllium tamper.

    I can't think of a worse death.

    The last guys to die like this who knew they were gonn More..

  • Note to self, use spacers between the beryllium shells. Got it, thanks.

  • An important lesson but it would be easy to assume that the accident that lead to this tragedy was a function of ignorance and naivety and that it doesn't happen anymore. Unfortunately it does. The Japanese have had criticality accidents using liquid solutions of plutonium salts despite knowing that countries like France Russia, UK stopped utilising solutions of plutonium specifically because they found it was too dangerous. A major accident at Dounreay involving a criticality event in a waste More..

    • @whogoesthere

      Reprocessing of spend nuclear rods involves their dissolution in nitric acid. From then plutonium in solution is inevitably produced. Of course, criticality has then to be avoided by using dilute concentrations and avoiding certain procedures. You can see in the following video in a lab environment what is routinely done at a larger, industrial scale: http://www.youtube.com/watch?v=89UNPdNtOoE

  • LOL what a hackneyed representation of frat boys playing with atomic weapons. Like they'd be standing around an unprotected sphere like that just sunning themselves in its radioactive juices. Pffft. I'm surprised Michio Kaku would appear on this kooky show.

      You've never heard of this accident before?



      On 21 May 1946, with seven colleagues watching, Slotin performed an experiment that involved the creation of one of the first steps of a fission reaction by placing two half-spheres of beryllium (a neutron reflector) around a plutonium core. The experiment used the same 6.2-kilogram (13.7 lb) plutonium core that had irradiated Harry K. Daghlian, Jr., later called the "Demon core" for its role in the two accidents. Slotin gra More..

      thank you

      Same, I found it hard to believe they would be so careless, but looks like even this radiation stuff started out with the most basic tools - a flathead screwdriver and an intrigued scientist...

    • @Saros

      That's a classic story together with that of Harry Daghlian. That sphere was not yet a weapon but only a research device, and at that time these materials were carried in suitcases and pretty much handled like in the video.

      Another interpretation of the same incident: http://www.youtube.com/watch?v=hh89h8FxNhQ
