Its not just fuel rods dunked in water. Water doesnt react to the uranium 235 fuel rods. A neutron source is entered into the reactor. The control rods which are full of boron stop fission from happening. When they start the reactor they slowly remove the control rods and the nuetron source (usually californium) starts to bombard the uranium fuel with neutrons causing fission. This heats the water to about 570 degrees F. The boiling water travels thru a condensor and it turns to steam. The steam turns a turbine which creates electricity. Ive probably said to much.
u need a moderator for the neutrons like water or graphite to slow them down. otherwise they are just "too fast" to get absorbed by another uranium core. if u add water and release the control rods (silver, indium, boron) the chain reaction starts. (they absorb the neutrons that were moderated to stop the reaction inside the water) as kenny said: there might be a neutron source to help it get going. but thats not even necessary. u can use normal water. heavy water or graphite as basic moderator. molten salts or gas is possible too. u need the right amount. in the right shape. with the right moderator. theres more than just putting some uranium together to get a chain reaction going :D just some neutrons here and there is just not enough.
The heat that fuel rods are so famous for is generated by the decay of fission products made of splitting uranium after it's in the reactor. But before the rods are put it a reactor it's just uranium oxide, i.e. a ROCK.
And not only are they not "melting hot", new fuel isn't all that radioactive. Perfectly safe to stand next to for a while, although you wouldn't want to sleep next to it every night. Kenny Williams is right, for a Boiling Water Reactor, but in a pressurized water reactor, we don't even use the nuclear core to bring the primary loop up to 570F. The reactor coolant pumps are so large and powerful that the heat energy imparted to the primary loop just by mechanical agitation of the pumps once turned on brings it up to temperature. Once up to temperature, then the reactor is started up to begin boiling water in the steam generators and turning the turbine generator to put power on the grid. Pretty cool process.
Yep after the war Westinghouse will be building a MOX fuel fabrication plant . Ukraine has uranium and zirconium and alot more rare earths as well. Westinghouse is going to build 8 , 1000MW reactors and Ukraine will be seeking South Korean to build 16 ,1400MW that way Ukraine will be self sufficient for electrical energy .
There is no danger of this. Reactor fuel is not anywhere nearly enriched enough to create a criticality and create a chain reaction of the type that would occur inside a fission bomb. You can bare hand fresh reactor fuel completely safely. It's super critical inside the reactor core. That sounds scary I know. All it means is that we're extracting more energy than we put in.
@@paulanderson7796 And that’s why thorium Wasn’t chosen60 years ago. Our whole energy pass would be different if the byproduct was weapons grade that was the simple reason thorium was kicked to the curb it’s clearly a superior fuel if you’re looking at everything

You mean the 94% of waste that is still usable in a reactor? Or the 6% still usable in density gauges, particle accelerators, smoke detectors or batteries for spacecraft?
@@zenthrosrion9147 Unfortunately the general public have a completely irrational fear of all things nuclear. And of radiation in general. This is a deliberate ploy by the establishment and by world governments.
@Matt S That's kind of where I was going. Too much money left in fossil fuels. Governments and oil companies aren't gonna hand that over without a fight. Hence the demonisation of all things nuclear. There is also lot of money to be made from the 'management' of reactor 'waste'. Personally I'd happily live right next door to a commercial power reactor.
Funnily enough oil companies are lobbying for solar, because they are dependent on natural gas backup. Shell didn't get where they are today by being delusional.
Really hi-tech stuff
Why are the rods not melting hot until they are put in the reactor ? Is it not just a bunch of rods near water tubes to make steam?

Are these pellets radioactive by any chance?
Very very slightly. Not remotely enough to cause you any harm. You can bare hand fresh reactor fuel pellets completely safely.

3:23 is he walking the fuel assembly there's four of them
Bulgaria is working with Rosatom , so they dont need your product at all .
Thank you, expert 😂
Nice, i hope someone care
Not anymore
Are them tubes super hot
Not until they go inside the reactor. Think of it like gasoline before it hits the engine.
Is there no danger of the fuel reach critical mass if the fuel pellets are all on a conveyor?

@@paulanderson7796 thanks for the info Paul. Just remember reading about the accident in Los Alamos in the 40's. Had too much fuel stacked up.

@@locobnojokofoooo12sadly. It's too good as bomb material too. Thorium is best as molten salt and that's comically easy to turn into weapons.

iS THERE ANY HAZARD OF APLHA INHALATION?
No. There's no dust in evidence.
@t صيانة وستنجهاوس
Nikola tesla estuviera decepcionado :'c
Porque?
Ur company needs to invest in how too clean up ur dirty fuel
Fossil fuels needs to invest on how not to damage the ozone layer

Can't say I disagree with anything you say.
Your company should stop all nuclear production and change to a clean energy that don't destroy the earth and its people!
Everyone 4 President It's the most green way of making energy...
Most murderous
Spoken like a true fossil fuel lobbyist.
Nuclear energy IS clean energy.
