Inside The Sarcophagus Pt5

[northroad1]

Haha this is nuts! Something like 500 roentgen an hour is lethal dose. So let's say they were next to the base of the reactor for 5mins, that is ~83 roentgen. Although exposure doesn't directly equate into dose absorption, I'm interested to know approx how many gray per year they received.

Scientist have brass balls and are some crazy mother fuckers, bless them and what they do!!

[crogeek]

You must have balls for doing this messy job. Respect to those big balled people.

[myrtlebox]

"It's 1000 Roentgen here! What are you up to?"

Oh nothing much, just looking at the lava flow from the base of the reactor.  It's pretty cool huh? Notice how the base was pushed down 4m - hmmm interesting.

GET THE F*** OUT OF THERE GUYS!!!!!!

[505JAM505]

@myrtlebox

Exactly!! 

[autentyk]

great job cutting corners. take another look at how you handled transition from part 4 to part 5.

[myrtlebox]

they only need to make a structure that will last 100,000 years

Not a problem!

[kANDzInS]

@wircolac

Mark your words!

[ESAPOWER]

@wircolac More accurately, what happened in the cold war.

May we never make the mistake of designing another nuclear reactor JUST for the sake of depleting nuclear fuel to weapons-grade.

[TheBoomViper]

"The inside of the sarcophagus is starting to fall down."

And this is way back in 1991. Just picture it today, 2010. They must build a new stronger sarcophagus around this one at ALL costs!

[TheCaptainLulz]

proof that the element with the most boring (pun intended) name can save the world. Boric acid is the supressor used. Oh, and it does miracles with swimmers ear too.

[Cab0cl0]

WTF, those scientists had Enormous Atomic Balls, to do a job like that!!!!

[Crisgo3d]

I am blown away with what little protection the scientists have. You would think they would resemble astronauts

[Digitalbumpin]

The Russians just weren't anywhere smart enough to build something like this.

The place should have been sealed from the start. The holes should certainly have been sealed up 5 years later at the very least.

[Nathantok7]

the soviet union will rise again!

[TheTomyossarian]

@Nathantok7 ...and what goes up, must come down. again.

[Gezab]

The Chernobyl facility was among the safest in the world, it was the human error in the control room that lead to the problem.

Don't act like you're some kind of expert on constructing nuclear reactors.

[Jemalacane]

They should hermetically seal that place.

[matdoomn]

I'm going to be using these videos for my next topic in science since we're going to be learning about the bad effects of radiation.

[TOMMYTRADDLES]

Chelyabinsk

[magicmaker15]

"Built in great haste." I would hope that they would not have piddely squacked around building it!

[GunsOfThePhoenix]

One question I have though is, where were there open ended tubes under the reactor, that allowed the lava to spill into those rooms?

[Detonater]

I can't help but wonder if anyone was under the reactor at the time and got hit by the reactor fuel as it flowed through the lower levels.

[GunsOfThePhoenix]

There was no one reported under the reactor at the time of the fatal test. There was 1 person next to the reactor, but he escaped.

[spazchickens]

I didn't know that they could go into that building.

[ExperimentalArmy]

Im surprised that all these years later the some of the lava was still hot and steaming.

[retards1ayer23]

1:32 DO A BARREL ROLL!!!

[spazchickens]

1:37 shows a sexy leg as well

[Perditionswrath]

question? why not employ petrolium oil as a dust supressant? It does not evaporate and wont add to any radioactivity.

[argonne5]

And if it catches on fire???

[starlionblue]

Your question has me thinking: why not also use a long hose (for safety) to spray petroleum oil in the area around the reactor lid to suppress the amount of radioactive dust should it fall? They could then try to install airtight doors to retard the movement of the excess dust. Has that idea been considered?

[Dodershift]

Why didn't they mention the prevention of the second steam explosion that may have been caused by the "lava" meeting the "bubbler" pool (no joke) hm, prehaps it was a bit too "gruesome" for prime time T.V. (if any one is intrested just reply and ill be happy to fill you in)

[stephendonnelly88]

Are you perhaps referring to the "mining expedition" which occurred under the reactor in an attempt to install a liquid Nitrogen cooling device?

[Dodershift]

no i was re-ferring to the "lava" that came dangerously close to entering the pool that supplyed water for the emergancy pumps had it done so there would have been a second steam explosion the only way to prevent this was by emptying the pool unfortunately the controls for the sluce gate where immersed in radioactive water, three vouleteers in no more than diving suits swam through the irradiated water and managed to open the gates however they never re-turned to the surface it is thought that..

[Dodershift]

. one of the men died before reaching the controls and the light that they had been given failed leaving them to feel there way along a pipe

[scorpionexo400]

how the heck did  they get a lid so freaken huge on there?

[belfastsamurai]

I'll be visiting Chernobyl next Spring, there's a tour leaving Kiev 6 days a week that takes you to the site and the neighboring deserted city of Pripyat. It should be an experience.

[xxhaloownerxx]

Be sure to take many pictures and videos for us :)

[stephendonnelly88]

That would be my intentions. :-)

[starlionblue]

Morbid as it may seem, if I were on vacation in Russia, I wouldn't hesitate to take a very quick tour around Pripyat or Chernobyl. BUT I ain't staying longer than I need to!

[weesparky08]

@starlionblue its not in Russia mate, its in Ukraine.

[r32adt3db]

So I'm guessing all these scientists died shortly there-after?

[stephendonnelly88]

Many have already died. Those who remain alive will be at high risk for developing a terminal illness in the near future.

[XxkutaapxX]

wtf? plutonium? i thought chernobyl only contained uranium Oo

[stephendonnelly88]

The reactor is fueled by enriched U-235. During the process of nuclear fission, however, several new elements such as Plutonium, Cesium, Americium, etc. are created as byproducts. PU-239 is created when U-238 absorbs a neutron, becomes U-239, beta decays into Np-239, and then finally beta decays into PU-239.

[Dodershift]

Are you sure? One of the advantages of the RBMK reactor design is that it can run on natural urainium and did not need en-riched urainium (or "heavy" water for that matter) so why would it be used?

[Dodershift]

[stephendonnelly88]

No reactor design can operate using non-enriched Urainum, which naturally contains 99.3% U238 and 0.7% U235. The U235 concentration must be enriched to about 3%-5% before it can be used for fuel.

U238 is technically fissionable, but does not support a spontaneous, self-sustaining reaction. A Mixture of U238 & U235 at 96% & 94% concentrations, respectively, is ideal for a self-sustaining reaction.

[stephendonnelly88]

Because the U-238 is present in large quantities within an operational reactor, it naturally is exposed to heavy neutron bombardment. As a result, some of the U238 ends up absorbing a neutron, becoming U239, which is a short-lived isotope that quickly decays into Np-239, and then finally in PU-239.

[stephendonnelly88]

One of the greatest dangers of reactors nearing the end of their fuel cycle is that they contain large concentrations of extremely hazardous by-product chemicals of the fission process (such as PU239).

Unfortunately, Chernobyl has more than half way through it's fuel cycle when the reactor exploded.

[stephendonnelly88]

*EDIT CORRECTION:

94% should be 4% in the above comment...

[dbcooper972]

@stephendonnelly88 Your reactor theory isn't quite up to par. CANDU reactors can run using natural uranium.

[MsMercury]

Wow, bless them for doing such dangerous missions. I don't think I could do that.

[jacko39]

that place looks spooky as hell at night. :-\

[Hemo443]

That place looks spooky as hell at any time of the day mate.

[jacko39]

i imagine it is.
