Nuclear Plant Breakdown

[billschoe43]

Is there going to be more World's Toughest Fixes with Sean Riley? Does anybody know?!

[Nycki1337]

Oh no! Core meltdown! Quick, take a video for the internet!

[oobeedoobenubi]

I work at this plant! We just replaced a bunch of LP turbines!

[HedgehogStudios1]

O great a BWR. Yep. There's totally not a 100% chance of a leak of radioactive water if the containment is breached

[coconu2shrimp]

Tepco applied nu-clear plant of NO7 and No8 which are new ones on 31th of march to goverment to build up in FUKUSHIMA. I am really shamed as a Japanese, how can they do say that they like to build up new one right now ?

I am sad and really shamed that i am a Japanese. It is not the time yet till they showed they can fix perfectly after they have a problem and this film might be wrong till Fukushima nu clear plant is fixed perfectly then. we must wait and see.

[wecanstopnwo2]

EVERYWHERE RADIATION IS GLOBAL, ONLY ONE NUCLEAR PLANT.

nuclear energy must be destroyed !! THE FUTURE IS MAGNETIC MOTOR !! info aobut free energy magnetic

[ObsenityofAtomicTech]

The industry was almost dead from its own genetic desease. But then Big ale gore came alone with his big lie and told us CO2 was just gonna get us all and you fools bought it are full retail and now think the most poisionus matter on earth is going to save us from CO2, that is on your breath right now and will aways be on your breath. Try some atomic fumes on your breath and see how long and well you live. Wake up this is about selling you a lemon that only a gov. is stupid enough to buy

[ObsenityofAtomicTech]

All of what they are showing can be run off of coal, natural gas, fuel oil, or anything else that can be burned. Atomic steam engines make mountains of atomic fuel piles that always forever have to be kept cool in water and that water has to be kept out of the water tables that we drink from . How well have they done that in japan right now even before it melts down and blows up like a volcano? And the cost for all that atomic fuel pile material in dollars and human contamintions, emense.

[TheDreadlocksRasta]

Nuclear Power might be the BEST but what about the waste it pruduces which aint exactly your common garbage!

[n310ea]

Damn, those rotors have a low life expectancy, you would think they would last around 10-15 years with frequent maintenance.

[team222badbrad]

@n310ea It was an upgrade not a repair.

[damaged01]

Dude looks like vanilla ice.

[CongressmanPeanut]

One of my teacher's friend's job was to clean radioactive material off the sides of aircraft carriers after underwater nuclear tests.

[train52000]

If you ask me, (not so much the video, but the power plant itself and no I not talking about the money, either), this seems like a giant science project. A+

[train52000]

I wish I had my own Nuclear Reactor, that would be nice. Of course it might need to be a bit smaller, to power my house and maybe even smaller to power a car.

[bibbyandal]

i presume this is a BWR reactor as theyre being so cautious with the contamination.

BWR's are an odd design i think

[friedie1jeff]

Beautiful job. Well done.

[123woodbridge]

it cant be good for your health when your working with nuclear radiation. right?

[WilDeRSkillZ]

@123woodbridge Not really , when everything is shuted down i think it is safe. and anyway if it was dangerous they would be with special clothing from radiation

[Lifewontwait29]

nuclear power is the BEST

[UnknownSoldierCOD]

If you think nuclear fission is safe, read all about Mayak.

[9hello123]

@UnknownSoldierCOD You mean somewhere from about 60 years ago that has no relevance to today at all, was a nuclear weapons facility not plant, and does nothing even remotely similar to any facility or plant today?

Yea I fail to see how that is even remotely related to present day fission.

[VTS1337]

Wow, dangerous

[RobloxFreak122]

Oh my god..... I passed those nuclear plants! I live in PA!!!!!

[angerfistbaSS]

nuclear power 4-life !

[1ownjoo2]

anyone know if there are any video's where they show the reactor's and cooling pools or just any tour of nuclear plants ? Besides teh chernoble ones i cant seem to find any

[moonwalker5058]

Man, such great technology and power!!!

[RobertsDigital]

So its both the Job of Mechanical Engineers and Nuclear Engineers combined...Heavy Task.

[deepwaterescue4u]

Nice vid I work these outtages on turbines and generators all the time. I love doing tearing these guy down and rebuilding them...

[AviationPhotogBNA]

Fascinating video! I worked an outage in the Turbine Room of a TVA Coal Plant in Kentucky. It's one of the world's largest coal plants and we had to to a complete retrofit and overhaul on one of 3 Units. Unit 2 was the Unit and this video shows the process in pretty decent detail. Obviously it takes days, but this is pretty cool to watch in just a couple of minutes! LOL!

[douro20]

The biggest problem is that this is a BWR. A BWR turbine takes the steam directly from the top of the reactor. It contains some short-lived radionuclides which have to be dealt with before the turbine can even be removed from its housing.

[meccaturbo]

@douro20 The main advantage of a BWR is the thermal efficiency. No steam generators as there are in PWR's.

[CHRIS1974100]

Nuclear is the best industry in the world. Staffed by a well trained specialist and people. No wonder the accident in this industry is just small

[violativelos3r]

@CHRIS1974100

yeah youre right but when things go wrong therye normaly disarstorous

[9hello123]

@violativelos3r no they're not. At all.

[ndaboro]

@CHRIS1974100 Nuclear power's dirty secret, the radioactive nuclear fuels process. It kills those who work in the radioactive fuel facilities. Over 120,000 claims due to sickness and death over 45,000 claims approved for sick and dead nuclear workers, over 1200 workers never have received their claim money-they are dead. U.S. DOE-DOL statistics, claim payments, over 4 billion dollars, since the atomic energy health act passed in 2000.

[Allante715]

@ndaboro

Don`t want Coal, Don`t want Oil, Don`t want Nuclear. What do you think we should get energy from? Magic and fairy dust?

[apard7]

@Allante715 solar hydroelectricity and wind

[iamacoolkiddo]

@CHRIS1974100 who the hell will let someone who're not well trained to manage the most dangerous power plant?

[illini1144]

@CHRIS1974100 yes it is!

[smokill91]

@CHRIS1974100 talkin bout japan now?

[coconu2shrimp]

@CHRIS1974100

It was not.

[Tritonium2k7]

@CHRIS1974100

never heard such  unparalleld bullshit.

[cicatrixta]

@CHRIS1974100 You changed your fucken mind yet dickhead?

[nealra80]

seen this done at indian point this spring ,it was an education to say the least

[RingshadowCat]

As a Radworker, rock on national geographic.

Re: Contamination, depends whether it's a BWR or PWR. In a BWR, a turbine will be contaminated, in a PWR, it won't be.

[orland9999]

Are you a nuclear engineer?

[RingshadowCat]

No, I'm in school for Power Production, specialization Radiation Protection. However, I've had some operations training in the past. Between that and my classes I'm pretty familiar with the basics of nuke power.

[orland9999]

I see. So why is it in a BWR (like in the video) reactor the coolant is in direct contact with the core yet the steam produced did not transfer radiation to the turbine?

[RingshadowCat]

It does. The turbine is radioactive. That's why everyone is in anti-cs and why everyone runs in with swiffer mops after they remove the turbine's casing. When the turbine is running, giant cement shields are in place to shield from any radioactive rays. Once the reactor is shut down and the turbine has had a few weeks, it' s just dealing with the contamination, mostly.

This is all as far as I know, I've only personally seen a PWR opened up.

[crozz131]

For the BWR Turbines, they let them sit for while then give it a full cleaning. Most of the contamination is surface level so it comes off with the cleaning. The turbine will still be a source of radiation after the cleaning but it will be small. About as much as a microwave. It will then get shipped to a refurbish facility to be re worked then it may find its way back into the same unit some day or a similar one. Im a pipefitter so I cant comment on the work but Ive seen many done in the past.

[ICANanimations]

I know that stuff is radio active and that touching it is fatal. but...

what about the radiation it sends out? cuz of his contact with the radioactive water isnt the rotor radio active to?

so I ask.

how large is the dose of radiation you get when your standing close to that thing?

[nbadil]

none because the rotor is only exposed to steam, the radioactive crap is separate from the rotor and turbine

[ICANanimations]

but the steam comes out of the core right?

[RLHubner]

the core heats the water and makes steam...

[ICANanimations]

ok I found a sketch now its clear to me.

the core is in contact with liquid dont know what.

that gets heated and heats the water to steam.

so I think that means no radio active water.

that water flows through the turbine causing it to rotate.

but if I'm wrong. the water DOES get in contact with the core. or get radio active, and than the rotor gets radio active to. just like the top of that thing. right?

[RLHubner]

It's like a pan with water and the core is the fire.

[ICANanimations]

so the rotor is contaminated. what is the radiation dose you get from it?

[RLHubner]

I don't think it really is contaminated... This video isn't correct. The water never gets in contact with the core, well, the radioactive part of it.

[ICANanimations]

ok agreed. video is wrong by saying that the top is potentially contaminated. :)

[RLHubner]

Yes, if it was they wouldn't be there with no special suits and stuff...

[UKRentor1605]

the control rods are encased in a containing metal which are all sealed, but they always say the water is contaminated because the casing is in contact with the nuclear material and some of that might come off, or even one of the rods may be faulty and may slightly expose nuclear material to the water. At most the water is very slightly radioactive, but even if it isn't they say it is because thats what the regulations dictate they have to say.

[ICANanimations]

O I didnt know that. I thought. once exposed always contaminated.

[RingshadowCat]

Depends whether it's a PWR or a BWR. in a BWR, the steam is made in the reactor vessel, which is the case here. In a PWR, the steam comes off a steam generator, and is not radioactive.

[ICANanimations]

so if you got a Pressurized Water Reactor the water gets heated by a seperate loop of liquid.

wich is in direct contact with the reactor.

and if you got a boiling water reactor the water gets boiled directly in the core.

I guess the turbine is dificult to replace that way.

so how do they fix a Boiling

[RingshadowCat]

Right. In a PWR, the primary coolant (reactor) is separated from the turbine by the steam generator. The water that spins the turbine never comes in contact with the water that cools the reactor.

How do they fix a boiling what? a BWR? Generally reactors don't need much in the way of repair..

[ReDbOAtHuNgGaR]

thats a small rotor, love my job,local 740

[icpfan19]

i'll be fliping out if i had to climb to the very top of those towers

[calebp9503]

like 10 million isn't serious money . . .

[GazBoffinThe2nd]

Thats spare change compared to the cost of equipment being dealt with here...

[nuclearcarnie]

At least spell it right...Bartlett. And where are they going?

[jw9626]

there goes bartlet

[schismtomynism]

solar power= product of a nuclear reaction (fusion). most of nuclear energy doesnt come from gamma radiation. it comes from kinetic energy yielding from fission reactors.

[mail062000]

they get paid A SHIT LOAD for that work

[DiscipleKray]

this may have sense since they can die anytime they do it ...

[luxemkingII]

well you could really have 80% of the earth only with solar panels if you want...

you see nuclear energy isn't really good but it's the best for now because it doesn't pollute the air and doesn't destroy lungs and it's very efficient...

it's like churchill said:

democracies are the worst kind of states, except of all the others...

[Anonomys999]

Solor power was invented around the 1930's and 1940's , since soler power came around so long ago, why are we still using nuclear power plants instead of soler power plants, its the same with win mils too, they generate power and they have been around for a long time.

[Aiucinante]

Because nuclear power is much more efficient than solar or wind power.

For wind, you need many wind mills and a windy location to generate power.

For Solar, you need adequate light and a lot of square footage of cover to generate power.

Even with that, the amount of power generated doesn't compare to the amount nuclear does.

[jayman10134]

nuclear is not more efficient, just more reliable

the order of efficiency goes:

wind

nuclear

solar

[gteea]

@Anonomys999 Solar plants and wind turbines will only generate up to 40 times the energy it took to manufacturer them in the first place over their life time. Very smart energy companies put these systems in place as a way of pleasing the 10% (greenies and environmentalists).The other 90% of the population want the coal, hydro and nuclear systems to stay as they provide us with cheap power.

[ludolorandi]

Moisture separators & reheaters underneath the turbine weigh about 185 ton

[schismtomynism]

wrong. moisture seperators come before the turbine (in a boiler water reactor, it occurs in the oulet plenum, and reheaters come afterward. there are typically turbine bleed sections, which is what youre probably referring to...

[ludolorandi]

You're right, but the MSRs I'm referring to come between the HP and LP stages of the turbine, where the exhaust steam from HP is reheated and the moisture it picks up is taken out again before entering the LP.

This is a BWR plant and has a steam separator and a steam dryer in the RPV. You're probably thinking about PWRs (which I don't know that well).

[schismtomynism]

this turbine setup consists of a single turbine, not cross compounded. most nuclear plants (bwrs, pwrs, breeder reactors, etc) use saturated steam. their turbines are designed with this in mind.

[gregrudd]

IIRC The only Nuclear power stations that use superheated steam are the British AGR's

[marj13yuki]

there are many types of nuclear waste depending on the half-live of such substances, i think it gives of berllium, depending on what type of radiation emitted (mostly alpha)...gotta calculate... do they still use uranium235?

[luxemkingII]

235U is the only isotope existing in nature (in any appreciable amount) that is fissionable by thermal neutrons

it wouldn't go without it

heavy water reactors use uranium with an percentage of 0,9-2 of 235U

light water reactors with slightly more than natural uranium which has 0,72%

and most of the reactors use low enriched uranium: lower than 20% of 235U

nuclear bombs, fast neutron reactors and naval reactors have highly enriched: more than 20% of 235U shouldn't pass more than 90%

[dirtmerchant06]

People who are scared of nuclear power are simply uneducated. I have been at Susquehanna, and safety there is the first priority of all it's employees. There is nothing dangerous about making power in this manner. Using coal to make electricity generates more radiation release to the public than nuclear power does. In fact, you receive more radiation from radon in your home than you do if you live within 10 miles of a nuclear power plant. Why are there no coalitions banning radon?

[iammrlee]

Maybe it is bcos radon don't remain radioactive more than a few months, while even depleted fuel rods used in nuclear plants must be stored for century and remains radioactive always.

Ingesting just 0.1mg of that radioactive dust would get you tumors growing like grapes inside.

Therefore the tight regulations and coalitions.

[luxemkingII]

they made tests:

people living near a nuclear powerplant have 10% more chance to die from cancer, but for now nuclear power is the only clean and efficient way and coal is even give an even higher healthreat than nuclear...tell that to the chinese

only one problem where with the plutonium???

[schismtomynism]

that is complete BS. they have been no studies proving that people living near nuclear power plants are more likely to get cancer. thats because the radiation released by nuclear fission is hardly measurable beyond background. there are natural radionucleides in the soil which release more. look at the beaches of brasil. FULL of thorium.

[luxemkingII]

yes there have been...-.-

[schismtomynism]

okay, prove me wrong. show me a link or something.

[luxemkingII]

o.k. first learn german, get the spiegel spezial of august or july 2007, there's your link

[MokomaSusi]

There is no such problem in Finland. Maybe germans should learn to build better nuclear powerplants?

[luxemkingII]

yeah germans have got shitty npp's some don't have cooling towers so the water flows directly into a river

Luxemburg doesn't even have an npp or kpp only wind, solar and hydropowerplants

[bear2cuddles]

Ya nuclear provides usable energy but what bout disposing nuclear waste huh? The worlds oceans are full of illegally disposed nuclear waste. Still think its a good form of energy? GET A CLUE.

[DRV275]

Damn, I was hoping to see Homer, Lenny and Karl and maybe even Mr. Burns.

[grantnw]

shouldn't they be wearing protective gear?

[ap327145]

none of that stuff radioactive...unless one of the secondary reactor loop pipes bursts or leaks which liquid is slightly irradiated

[LovelyYTRocks]

I mean uneducated mother fuckers who are scared by what they do not understand.

Nuclear does NOT mean dangerous. Seriously, learn your fucking vocabulary.

Nuclear energy provides way more usable energy than anything else. We should start using nuclear energy, solar energy, and hydro energy.

[nsink77]

I know the way the video is titled gets more attention, but its actually called a "shutdown", not a "breakdown". I shutdown is scheduled about every 18 months for routine maintenance and to refuel the reactor.

[BellaOfBacardi]

That part where he said something like you don't call the hardware store for one of these was pretty funny!

[rl0u8888]

we need more nuclear power...we r gonna start using it sooner or later, why not start now and save big bucks :D

[DominicHunt]

That's actually kickass.

[chris7777777777777]

4:44 - 4:45 the guy in the green is X-military the way he corrects himself and puts his hands behind his back you can tell, haha  I even do that to people who are non-military sometimes I don't even realize it.

[SuperBravoOne]

nuclear power is so awesome. I wish we used it more. Dump that waste in space via missile.

[DiscipleKray]

well i think somehow he is right .. leave the thumbs down for yourself angry youtubers. Nuclear power is THE greatest way to make energy if we master it ... but we gotta do something with the wastes .. like throw them on comets that comes close to the earth like haley IDK or even the sun but that would be dangerous, w/e, we still need to master that energy.

-Kray

[jetfighter2011]

Dude, there is little/no waste... if your talking about waste cleanup... that amount is MINIMAL. My boyscout leader worked @ a nuclear power plant, he says its the way of the future, today! I agree :P

[DiscipleKray]

it is the future ! but we need to master it :P i gotta ask you why is your youtube account called Jetfighter2011 ?

[luxemkingII]

O.k here's the thing if you would shoot the waste in space and there would be only one malfunction and it would explode you wouldn't like to live on earth anymore...

and the waste that is always emmited is really easy to clean up but the plutonium rods emmite gamma rays which would kill you in seconds if smth. goes wrong the clean up isn't easy at all--->see tschernobyl sarcophagus it was the only way to ''clean up'' the rest of the mess but what is inside there is impossible to clean up

[luxemkingII]

O.k here's the thing if you would shoot the waste in space and there would be only one malfunction and it would explode you wouldn't like to live on earth anymore...

[schismtomynism]

what are you talking about?

[luxemkingII]

the rocket would malfunction, then explode and you would have a tschernobyl 20 times worse and spread over the whole world

[MastaRikta]

No, see, the plant would have exploded.

[Jewishfan]

We should use more solar power. We have sunshine for FREE!

[MonkeyScout]

Solar power is impractical for now. Maybe in the future.

[kukusasuke]

cancer is a lot more impractical.

[MonkeyScout]

Cancer is unlikely.

[luxemkingII]

nuclear energy = clean energy(waste not calculated)

solar power = clean but not efficient enough

[kukusasuke]

well waste MUST be calculated.

what could really work is thorium instead of uranium, the resulting waste would still be radioactive but it's halflife would be at most a couple of hundred years, not geologic eras like uranium shite...

[luxemkingII]

if you want a cpp then there will be a lot of co2 in the air and the small particles would detsroy your lungs

they do have a theory to build a pp by burning the nuclear waste emmited by npp's

[schismtomynism]

uranium isnt the problem. it's the fission products like Cobalt-60. thorium is already used in breeder reactors, but due to treaties we have with russia, we don't use them because they yield plutonium as a byproduct (which is weapons grade nuclear fuel).

[RingshadowCat]

The radiation you're exposed to from a power plant won't give the workers, or you, cancer. Being near a nuclear plant generally increases your dose by less than 1 millirem a year or something equally exponentially low. You get 1 millirem a day or more just from background. Google for a background radiation survey, it'll break it down for you.

[MastaRikta]

Homer Simpson must have been off that day.

[MonkeyScout]

How do they dispose of the old piece?

[ap327145]

since its not really radioactive they usually bury slightly irradiated materials like the reactor core vessel but i wouldent be too surprised if they recycled it into new nuclear equipment

[toonrunedudehobby]

i would be scared as hell to be within 50 miles of a nuclear power plant, let alone inside one where exposed radioactive nuclear waste is in unconfined conditions hanging from a crane falling on the floor within 10ft of u.

[ruehlco]

That's some intensive work! Drop and the $5 million is wasted down the drain.

[wiktorkramer]

why the fuck me need this?!

peace people -.-

[KrazyRawb]

Education..

[gregor00005]

So that i can get smarter then you.

[BigEvan96]

Having a nuclear reactor is not an act of war...Its so that an infinite amount of energy can support millions of homes and 10mill to replace it is well worth it.

[LovelyYTRocks]

Oh boy.

What an uneducated fuck.

The word "nuclear" doesn't mean "explosive" or "dangerous".

How is heating up water and using the steam to power turbine dangerous? It can be repeated over and over again.

What an uneducated fuck.

Learn to nuclear.

[wangb13]
