Natural Nuclear Reactor 

It’s cool how Mister Manticore can use the most unassuming things and edit them into something truly terrifying

1:54 for certified Mister Manticore classic

I love how half the people here are science people and the other half are Trinity Desk Project fans (like me)

this is a certified natural nuclear reactor moment

I guess everyone searched up "This was a natural nuclear reactor" after the mister manticore video.

Hi I'm one of the dorks who came here because of the analog horror video series but I did watch the whole thing and it was really cool and informative. Thank you!

I'm glad I'm not the only Mister Manticore fan who recognized this.

This is definitely a Natural Nuclear Reactor

Imagine after three years, the uploader comes back only to find out that 1:54 was memed to oblivion by a bunch weirdos talking about invisible humans.

i Hope i don’t turn invisible

Love how the comments exploded right after the Trinity Desk reference

1:53 ok mister manticore

1:54 roanoke moment

Kid named The Croatoan

Look closely and you can see the otheroppenheimer

1:54 This was a natural nuclear reactor

THIS... was a natural... nuclear reactor.

Yep the next time my neighbor complains about my reactor in the back yard I'm going to tell him oklo.

Do you see him?. The other Oppenheimer.

No one will ever get these references to The Other Openheimer anymore😔

This is truly, a natural nuclear reactor

Ronoake Colony was found abandoned in 1590 The residents didnt disappear they we’re turned invisible by a natural nuclear reactor

The Other Oppenheimer.

"Now don't think an underground river is like some amusement park ride...", when I was thinking exactly that 😂

Holy shit I work at that University. I had no idea he got that soundbite from someone where I live.

Some more detail on this can be found in James Mahaffey's excellent book _Atomic Awakening:_ ---------- The uranium had been sitting there for billions of years when something changed and groundwater started leaking into the underground deposit. The water acted as a moderator, slowing neutrons down to fission-producing energies, and the reactors fired up. The reactors operated in pulse mode, with the water being heated to a few hundred degrees Celsius, boiling away, and temporarily shutting down for cool-off. The operating interval was about 2 hours and 30 minutes. The power production continued for a few hundred thousand years, which, needless to say, is an admirable and unprecedented working life for a nuclear machine. They produced power at a rate of 100 kilowatts in the form of heat, made 11,907 pounds of radioactive waste, and 3,307 pounds of plutonium. The water-logged, sandstone/shale structure of the Oklo mines is hardly an ideal geologic depository for nuclear waste. We would never consider using such a place for long-term storage of radioactive fission by-products. Yet, in 1.5 billion years the toxic remnants of the Oklo reactor operations had barely migrated a few centimeters. Nothing poisonous had made its way into the ground-water, there was no evidence of biological harm, and the highly radioactive fission products had remained in place until they decayed into stable end-products. Mother Nature had effectively built a power-reactor cluster, pulled the controls, and ran the thing for a long time without causing any harm.

Cool video, I sure hope no English civilization turns invisible and can only be revealed via nuclear explosion

This was a natural nuclear reactor.

I took trade classes in welding and heavy equipment operation. This guy is so fascinating to listen to, I totally would have taken his classes as electives if it was an option.

Can we just take a minute to admire this man's ability to write backwards with such ease? Lol

Who else has to thank the RU-vid algorithm for randomly recommending this?

1:54 HE SAID IT! HE SAID THE LINE!

this dude is 100% college professor, like intense flash backs are happening right now

This was a natural nuclear reaction

Dear Illinois EnergyProf , Thank you for these videos. I love the balance of Expert Vs Novice level you achieve and your engaging presentation I have enjoyed on all of your videos, that I have watched.

A concise and melodrama-free presentation of the findings. I appreciate your effort. Thank you.

ROANOKE

Now this, this right here. Truly a natural nuclear reactor moment. Oppenheimer would be pleased (both of them).

Scientific American magazine did an extensive article on Okla natural reactor about thirty years ago

THIS IS A NATURAL NUCLEAR REACTOR

"It was ancient aliens!" might say the crazy man on the History Channel at 4am. I remember my father told me when I was a kid about these natural, nuclear reactors. It was a magical, Sci-Fi story about a real-life thing.

Wait a minute... This guy is writing backwards

Professor Ruzic is not just honestly smart, but a genuine good person.

I have found the squeakiest marker on earth.

Go to 1:54 for a true natural nuclear reactor experience

"Nature has a nuclear reactor." Me: **points at sun** "Fusion, too."

I have adapted to the squeak. Damn He skrawls gūd.

I am very interested in nuclear energy for Australia and I love learning information from people who are extremely knowledgeable in this field. Thank you Professor.

I thought this was an urban legend. Interesting piece of history.

Great topic, excellent presentation. Thank you.

This is one of my favorite RU-vid Videos ever as it deals with one of my favorite subjects ever: Natural Nuclear Reactors!

Thank you for your time and patience

This guy is good at putting things over in a simple understandable way👍

Really enjoying your many videos on nuclear energy. Great content👍

Amazing channel!! Thank you!

What a brilliant mini lecture thank you for educating me on this

One of the best science lectures I have ever heard! Thanks Professor🥇

Natural........ yeah sure

Excellent! The best presentation I've ever seen regarding the topic! Wow, impressive and will use as an example to re-enforce the paradigm of thinking along with recycling/concentrating waste, nucleosynthesis and advanced areas of opportunity to remediate waste into more valuable elements.

Thank you; great presentations!

That's a very squeaky pen!

What an awesome lecturer!

Excellent professor.

You make Nuclear science fun....I'm learning a ton!!!! Thanks, Professor Ruzic!!!! :)

I work with depleted uranium everyday I can imagine mining the concentrated version and doing it without it burning. We were told once the depleted uranium was lit it's impossible to extinguish

thankyou. nice work.

Thank you so much for very clear insight, my knowledge of energy science just went up by a lot

wait is he writing backwards for the sake of the audience?

Man I love this channel

Great Video

Great video

I love your videos Professor 👍👍👍

I love how Professor Abel Bliss can write backwards (to him) so we, the viewer, can see what he's writing. I learned to write upside down when making a technical sales proposal to engineers. They loved seeing a new way to present information that made them the center of attention.

super strong case for storing nuclear waste deep underground, away from water tables

Ruzic sir you the best...

Excellent 👌

Well, this video sure started with a bang!

I love this guy............. Thanks

+1 for including citations

Brilliant

Sounds fantastic. Can you tell us how the uranium glass sheets have been found in many places around the world ? Oh don't forget radioactive dust layers too.

Man can create atomic fission, but not a silent marker. Awesome video, by the way!

How many other sites outside of Oklo had this happen?

I wasnt aware of any further natural reactor finds outside Oklo

Fascinating!

Beautiful

_People: _*_*Invents time machine*_* _Nuclear Industry: _*_*STONKS*_*

This is beautiful, absolutely beautiful of nature.

Well that was fairly interesting.

Fascinating

Fission products (8:15): where did they go (8:30)? Well, you might try looking at the beaches Northeast of Rio de Janeiro, Brazil; however, you'll have to put Pangaea back together again.

1:54 WHAT!?

So the waste stays in the reactor? Is that safe (and possibly) in human created reactors?

Modern "natural" nuclear reactor work in Australia. Arkaroola, South Australia. Hot Springs. Do NOT reccomend:radioactive and very VERY hot. "Paralana geothermal springs are located on Wooltana, north of Arkaroola. Local granite rocks contain elevated levels of uranium that gives off heat during radioactive decay."

I am no smartypants on nuclear reactors, but i have 2 questions. First of all, how did the reaction start? Secondly, doesnt the water need to be like very very very clean water in order to be used as a moderator?

this. was a NATURAL. nuclear reactor.

What was the startup neutron source for this natural nuclear reactor?

Geometry of the geology! Great turn of phrase

great guy. watching him write backwards on the glass is fun
