Their major asset for developing nuclear weapons is the Natanz uranium enrichment facility.

It doesn't have anything to do, in specifics, with centrifuges, with uranium enrichment.

It's less than one percent of uranium, it's about 0.7 percent uranium.

Hardly at all. That's why it is still around. Uranium, two isotopes uranium 235, uranium 238 both of course are radioactive.

Yellowcake uranium, Mark.

Well I just discovered from the Department of Energy's data that the enrichment of uranium produces 93 per year of the CFC gas in this country, which is currently banned under the Montreal protocol.

Uranium hexafluoride is a gas.

Uranium tetrafluoride is in solution.

Uranium is used in the production of nuclear power.

He is not protecting himself from the uranium, he's protecting the uranium from himself.

And then we get to uranium.

This is a handful of these uranium oxide fuel pellets.

They took natural uranium, and they separated those two isotopes, highly enriched it in uranium 235.

It's going to stay in solution. But the uranium will come out as uranium hexafluoride, a gas.

And uranium 233 is being consumed but the neutrons from the fission are making new uranium 233.

It became uranium 233. Isn't that cool?

These lovely ladies are uranium fuel rods.

GLaDOS The Enrichment Center would like to announce a new employee initiative of forced voluntary participation.

Enrichment Elementary School's Japanese Magnet Program, students follow the Oregon State Curriculum.

Large uranium reserves for nuclear fission still exist.

The radioactivities are mixture of Uranium and Plutonium used in Hiroshima and Nagasaki.

Here's the decay chain that uranium 232 is on.

like uranium, plutonium, and everything else when they decay.

So, uranium, which is very big, wants to split.

You wouldn't happen to have any uranium on you?

In the enrichment strategies, of course Jen, it's going to play an important part with that. gt gt Connie

They say to me, We're going to run out of uranium. I said, OK.

Well, uranium dioxide's a ceramic, and ceramic doesn't like releasing what's inside of it.

And this was really hard. It took big factories, very difficult to do isotopic enrichment.

You're fissioning uranium 233, but you're making a new one.

Coal contains small amounts of uranium and thorium. They go up the stack, they're dispersed.

It breathes this uranium as it goes along, so it's kind of like a candle.

You hit the salt with fluorine gas, and what'll happen is... There's uranium tetrafluoride, four fluoride ions, and there's uranium hexafluoride, six fluoride ions.

Other students might be interested in a particular enrichment topic that they want to pursue individually.

They'll put the most enriched ones in the middle, and then they'll kind of decrease the enrichment along the length of the fuel assemblies.

Now What about thorium and uranium? Both are naturally occurring materials.

The uranium and plutonium took on a gas form to escape.

You can see that uranium 235 is on par with the abundance of silver and platinum.

At that rate, the known reserves of uranium would last for only 10 to 20 years.

It basically boils down to the Bushehr nuclear power plant and to the Natanz fuel enrichment plant.

Reactors in the United States, we're extracting about half of 1 percent of the energy that's in the uranium.

luminosity densities by about the fact of 1,000 or more which is like between uranium and air.

recently, eh.... as being a country that offers a world class environment for the exploitation of uranium.

Uranium 233, if you hit it with a neutron it will fission.

And with current reactor technology we really don't have very much uranium.
