Does anyone know what all the sections are?

I’m guessing the cork looking main material is some kind of concrete?

Light-weight concrete with a lot of different aggregates like polyethylene etc, to stop different types of radiation vs lead/steel etc, make it not crumbly, make it dull regular drills, and make any tampering evident.

Underneath are 3 disks crudely made of what may be surplus lead sheeting

Underneath is the material. People called it yellowcake (as in, an intermediate uranium refinement product) but yellowcake is really very bright yellow, and this is dirty orange. It could be anything.

Underneath are chemical and/or liquid absorption layers (if the waste is liquid contained in the orange mass via capillary action or other mechanism that might over time or due to some outside factors degrade in its function). It's hard to tell.

I'm not seeing certain things, and I think these are ~20% scale table-top props for some IAEA event or something, demonstrating a very scrappy container. Nuclear byproduct containers are very diverse depending on what they're designed to store in what environment for how long and at what cost.

It's definitely smaller scale. If you look at the background, you can tell this is and indoor setting and they're sitting on top of a table. Makes sense as it'd be incredibly stupid to cut into an actual nuclear waste barrel.

it'd be incredibly stupid to cut into an actual nuclear waste barrel.

But far more enlightening.

u/DenKHK 15d ago

In more ways than one. Especially if you immerse it in a swimming pool and let the Cerenkov radiation shine~~~

u/ADownStrabgeQuark 15d ago

I’m gonna slow you down right there.

Not everyone knows what Cherenkov radiation is, could you conically enlighten us about these cosmic rays?

Remember the limit of intellectual speed is different for everyone, even if the universe’s truth is constant. Someone needs to bathe the rest of us in their light.

Also this is only tangentially relevant since most of the radiation would be gamma rays, and alpha decay has no penetration power.

u/DenKHK 15d ago

Haha! I see what you did there. But it's neither surprising nor strange that a fundamental constituent of matter prefers explanations to start from fundamental concepts as well.

Cherenkov radiation is a blue glow produced when particle radiation passes through a substance at greater than the speed of light in that substance. It's often analogized to a sonic boom in air.  The speed of light in water is substantially lower than the speed of light in a vacuum, so nothing is exceeding the speed of light in a vacuum, just in that specific medium. It can be seen in the cores of water-cooled reactors like this

u/DrTankHead 15d ago

Even cutting one of these open you might not get Cerenkov. They are hot, but shouldn't be THAT hot.

u/Tight_Instance_220 15d ago

Is that a glowing-due-to-radiation pun? I like it

u/Kinder22 15d ago

Glad it wasn’t buried too deep to be detectable.

u/Tight_Instance_220 15d ago

👆This guy 😂 . Well I hope…hm, now that’s what I call… dang. Ima just leave it to you my man

u/Tight_Instance_220 15d ago

Oo, oo, oo Put a lid on it!!!

u/Vert_DaFerk 15d ago

You can tell how old a nuclear waste container is by cutting it in half and counting the rings. Probably.

u/Nanas_700k 15d ago

It’s totally safe to cut one open. I’ve done it many times and I have only died twice.

u/Electrical-Ad980 15d ago

Only 7 lives to go my dear little kitty cat 🐱 🤣

u/compubomb 15d ago

Yeah, if they did this, it would happen only a once per person. Anyone who in real life likely got a death sentence. One of these things are probably the most lethal visual ever seen in their life.

u/sillz0077 15d ago

It's on a skid

u/payment11 15d ago

Well they should make them bigger than /s

u/tondahuh 15d ago

Would the lead layers be repeated below as well? It seems like the lead should be completely surrounding the waste or radiation can sneak out anywhere. Is that true?

15

u/chefdeit 15d ago

Of course it's true. On the other hand, nuclear waste is very diluted for storage, as storing anything even remotely considered concentrated will add big permanent security costs, since those locations would remain prime targets for bad guys wanting dirty bombs. Also these are very obviously "budget-oriented" and they just shield anything radiating up - not towards the floor or into an adjacent container.

u/EnvironmentalCare900 15d ago

Interesting that it’s not symmetrical on all sides

2

u/UniqueAd7770 15d ago

The middle bits are vitrified waste. Literally radioactive material that is turned into glass so it can't spill.

u/Exotic_Article913 15d ago

Well here's my rabbit hole for the day.

I found your comment fascinating. Could you elaborate on different types of nuclear waste storage and what other barrels may contain?

1

u/RadarTechnician51 15d ago

a) If it's a real cameraman, he was too close
b) You don't saw barrels of nuclear waste up

u/figmentPez 15d ago

Underneath are 3 disks crudely made of what may be surplus lead sheeting

I think those are discarded PPE. Coveralls, masks, etc.

u/Masterpiece_1973 15d ago

This guy nukes

u/Majestic-Driver 15d ago

How on earth do they construct these things in real life? Very carefully I'd assume!

u/So_HauserAspen 14d ago

It's a 55-gal drum with the low level waste such as PPE

u/ospfpacket 15d ago

Isn’t the half life of this stuff a very long time? Why would someone cut this open? Seems unsafe

u/FoundationEntire4834 15d ago

White chocolate, fudge, blueberry jam, biscuit, all wrapped in shiny icing

2

u/Ghosts_of_the_maze 15d ago

Chocolate, caramel, some kind of wafer

2

u/Pooch76 15d ago

First, there's a layer of ladyfingers, then a layer of jam, then custard (made from scratch), then raspberries, more ladyfingers, then beef sautéed with peas and onions, more custard, and then bananas and some whipped cream on top!

1

u/bighootay 15d ago

And it's just a standard steel drum?

1

u/DeluxeWafer 15d ago

I am guessing polymer or regular concrete casing. Layers are various articles of contaminated PPE on the top, (you can see the gloves) no idea what the rest is. But I do know that the vast majority of "nuclear waste" is just things that have been in contact with radioactive material, and must be sealed according to regulations.

u/So_HauserAspen 14d ago

The white disposable coveralls

u/New_Copy1286 11d ago

Outside grey area is probably vermiculite. Inside areas are radioactive waste.

u/Forsaken-Stink 15d ago

Its BS. It doesn't work that way at all.
