Uranium from the Ground 

If I could only get a series of videos like this for the entirety of the sciences disciplines, I would happily learn everything.

You had me at radioactive dinosaur bones.

I did not realize how much there is to Nuclear Engineering. This guy is great. He helps on the high level to supplement the MIT series which is a deep, deep dive- sometimes confusing.

Scientist call something a cake and then they dont allow you to eat it...

I like how he is a right handed guy on the classroom and a lefty on the glass marker.... Magic of video inverting

"Don't worry, the uranium is in a triple layer of protective sandwich bags!" Best line I've heard all week

01:56 Pauses: "-Nope, I am not reading that word"

I'm so glad I found your channel! These videos are great! I'm sure I'll watch them more than once!

Why would anyone down vote this? It's just a factual discussion of where uranium comes from.

You are awesome! Thank you for making and sharing these videos!

Edmonton City Center airport was where the yellow cake, in 45 gal. drums, from Uranium City used to be flown to. So yellow cake got all over the inside of the hanger, and elsewhere, according to a mechanic I once talked to. The land is no longer used as an airport, but it has yellow cake contamination. Their hanger was at the west end of the airport. Developers have declined to develop the property. Most people don't know about the yellow cake contamination.

Really nice video thanks for doing that. 😊

This knowledge is A+

Mmmmm. Yellow cake. What kind of frosting? Sounds delicious. More great content professor!

Fascinating

I just found you! Love 💕💕💕 your content

i love your into

Excellent video sir. A question that intrigues me is what causes the material to become radioactive? The earth is so fascinating and its creation of these materials

thanks for such detail! That explains why its important to do ventilation in the building: concrete is made from sand and any sand should include some micro parts of either uranium or other related to its decay radioactive elements which eventually will generate radioactive radon in any building with concrete components.

Nice video - just curious though. I remember seeing various stories about outrage over uranium mines by locals near to them regarding pollution (whether radiation, or chemical from what is used to separate out the yellow cake). Whether it was water supply or just more general soil pollution. It would be good to hear a bit more about that.

Radioactive yellow sand... I'm now reconsidering going to the beach again.

To generate 1GW of electricity for one year requires 940 kg of U235 and 23.5 tons of U238 that is processed from 210 tons of uranium from 165,100 tons of ore. A thorium molten salt reactor will require 950 kg of thorium 232 to produce the same amount of energy.

The mill tailings still seems like a good source of sand for concrete highways. Since they aren't enclosed structures, the radon isn't a problem [can't be concentrated] and users are all shielded from the low level radiation emitted by the vehicles they're riding around in...

Wow

i am a bit confused about U3O8 . Oxigen is minus 2 as in H2O in a covalent bond. .8 atoms makes minus 16. So how does uranium fit in ?

And binge watch I shall...

Any talk about Thorium?

Uranium is cool and all, but are you really able to write backwards that proficiently? I'm in awe.

I can remember as a kid in the 1950's, everyone thought they could buy a Geiger Counter and wander the deserts of the SW and get rich.

Would love for you to do a video on the economics or benefits of fission and fusion. Why is fusion so coveted?

And the bit about breeder reactors?

how does a Geiger counter find fossils? if the uranium made them then isn't there uranium around them still?

By digging out the sandstone and grinding it up one does pollute the environment. Something what was fixed in the ground is now taken away by the wind.

For a lot of people, business comes before peoples lives.

U235 is 0.7% of natural uranium and costly to separate. Sadly the light water reactors we use today, use only about 3% of the energy contained in the fuel. The irradiated fuel is then stored. Molten salt reactors can burn 99% of the fuel energy. The Canadians at New Brunswick are building a plant that will use waste irradiated fuel to power the new reactor. No need to mine anything as the fuel is sitting in deep water tanks.

How did uranium get into dinosaur bone I didn't get it.

Ahhh... Yellow Cake! Now Dave Chappelle's skit makes sense. I can't be the only one.

Whose ranium?

You have forgotten to mention that reactor producers have created a cartel like situation when it comes to the supply of uranium i.e. buy my reactor and get fuel for its life. Russia and France are two of the countries that have such a policy.

Got that Yellow cake Don't drop dat shit! Chappelle show

Why is Uranium mined at a Uranium mine and not from Coal ash? I have heard that fly ash has more energy in the ash in the form of thorium and Uranium then the coal did in the first place. Also Thorium is found along side rare earths so rare earth mines can pull Thorium out of the same ore that they are getting neodymium and friends from. There is no need for additional mines, not at all just an added step at existing mines

I just saw information as to the quality of drinking water in the US. There are a few states which have undesirable levels of Uranium (Exceeding EPA Standards) in drinking water. I am happy not to be living in those places. One of those states is a red state which has been continually touted as a large success in recent decades for population migration. Good Luck to those folks!!

Assuming energy resources permanently run out, that is to say they are (finite), there is no point in killing each other - USA, N.Korea, Iran and so on, over finite resources because even if anyone emerges as the ultimate winner after killing off all other competitors, that winner will eventually be met with a resource depleted world, meaning they would in the end - after all that murderous struggle & victory, die too. Surely our intellect should enable us to see such an out come. Assuming that energy resources do not run out permanently - which it seems is the case, but rather there can be periodic shortages, we can do one of two things. Either we continue to kill each other using the resources we have accumulated, from sources that do not run out permanently - a completely and utterly wrong thing to do, to use up the very infinite resources to destroy ourselves, or use those very resources to find more resources there by mitigating the shortages. This choice has been open to us since the dawn of our existence and will always be until we wake up to it. If we assume that humanity has a half life of 100 million years, the point being it is much less than the half life of elements of Uranium or the sun (sources of energy), this means the human life will run out (extinct) way long before these energy source will do. So these energy resources are infinite with respect to the humans maximum life spun. It seems we are killing each other under the mistake that resources run out permanently which is not true. They are sometimes in short supply. It is smatter to use the resources to find more because it is endless. I hope we learn this and quickly change. Both war and peace require huge investments one is unquestionably better than the other. Finally evidently no energy resources have really permanently run out in the last 1000 years. There is only theoretical speculation that they could run out permanently based on a mono-intellectualism.

yellow cake oishi

Writing backwards was impressive 😂

Australia also has a very high concentration of outraged lefties, might be the highest in the world too, we have coal and gas in plentiful supply too, but we pay absurd prices for electricity because of the high concentration of lefties.

“One ton of the good stuff is enough to power a nuclear reactor for three years” If you read the Wikipedia article on Fukushima, each of the four reactors there had around 60 tons of Uranium in them. So…it’s not as merry as that. I guess the concentration of “the good stuff” is pretty low.

I'd be curious how we could do any of this without a constant supply of petrol - seems to me the world is headed toward a collapse given that we have declining ERoEI rather than increasing ERoEI - and given that we have no substitute for oil - once the oil decline is terminal, how will we mine iron, coal, u238, nat gas, silver, potash, nickel, cobalt, lithium - do we intend to keep up this way of life without petrol?

is it generally thought that asteroid impacts brought the uranium here to begin with? (all the heavier elements already here at the planet's formation sunk to the Earth's center when the surface was molten)

In Australia, even the very rocks are trying to kill you.

My hous nier thow mach from somalia

I think you meant densest element, instead of heaviest?

Something Doesnt Make Sense About the So Called mill Tailings .... If it were Valid that this is Nothing but normal regular sand and All they did was extract uranium from it an put it back it should be Less Radioactive . Hence it Should be even safer than regular sand with the uranium Not Extracted . Can you Please Enlighten me As to Why This is .

When you say 1 ton of U can run a plant for 3 years, are you talking about conventional water reactors, or MSR's?

Thorium

dude sounds like james garner

How can he write backwards ?? Must have a lot of practice

"oh look, yellow make up"

How did an ancient original element like uranium end up so richly sequestered in a sedimentary sandstone?

,whoen I do the laundry I have to searchh through the Nucleaf sock sock to sort out and find the missing socks their are always some matching socks in the nuclear sock pile and I think T- Rex used to wear Argile socks Vanna

Don't mean to act like a little kid but he stopped after Australia 😂

Czech Rep - west Bohemia - big source of Uranium, mined by political prisoners during 50's - when communists took over, mined for russian nuclear programs

Fission is expensive and inefficient. Centrifugation is the best.

i bet it tastes like yellow cake heheh...

Hi North Korea!

haha my liek is the point between 1.6 and 1.7 k likes lmao. i do love physics.

Your little map missed out the uranium in the UK and also the Congo in Africa, where the US gets 90% of its uranium from, or is that kept off the maps?

Read a book

I thought uranium is worth more than gold.

Q. What do you call a bankrupt fella from Tehran, suffering from malnutrition and exhaustion? A. A depleted Iranian. 😉

Very superficial coverage, and also dated. The Ranger mine pictured isn't a sandstone host, it's an unconformity deposit hosted in a carbonaceous schist.
