You have to build a water cooled reactor as a pressure vessel.

That's what makes it that you cannot burn up uranium 238 in a thermal spectrum reactor like a water cooled reactor like a CANDU or like a water reactor.

Nuclear right now means water cooled reactor, uranium oxide solid fuel, poor fuel efficiency and steam turbine.

A big pressurized water reactor vessel.

And this reactor doesn't use water.

Now it's important to understand that this room is cooled by water, heated by water, filters its own water, and it's powered by water.

So water cooled reactors have to run at over 70 atmospheres of pressure.

The heavy water reactor will use about 0.7 percent energy value and the light water...

line with the light water reactors. It's funny, even at that time 50 years ago, nobody thought the light water reactor, the heavy water reactor would be around very long.

Weinberg was also the original inventor of the pressurized water reactor.

The heavy water reactor will use about 0.7 percent of the uranium's energy value, and the light water reactor will use about half of one percent.

Metal contracts when cooled.

It has cooled off.

Reactor.

The reactor that we worked on is cooled by a liquid salt, a nuclear fuel in the form of solid pebbles.

A high temperature reactor could be useful for other purposes even if it never propelled an airplane. He knew that to make the nuclear airplane work, they couldn't use water cooled reactors.

Reactor status?

Reactor coolant.

Reactor bay.

In water cooled reactors, you generally have to provide power to the plant to keep the water circulating and to prevent a meltdown.

We can fully burn up the thorium in this reactor versus only burning up part of the uranium in a typical light water reactor.

Reactor core temperature.

Reactor, that's right.

To the reactor?

I cooled the patient's head with ice.

My love for him has already cooled.

Here's why water is not such a great thing for the inside of a nuclear reactor.

Now, in a water cooled reactor, you have a system called a recombiner that will take the hydrogen gas and the oxygen gas that is always being created from the nuclear reaction and put them back together, because chemically they'd much rather be water than being hydrogen and oxygen.

They're targeting our reactor.

The reactor would breach.

It's the warp reactor.

Lock on their reactor.

Fire up the reactor.

The reactor is close.

What are we going to do? About that time, the Air Force said, The navy has built their nuclear submarines and the Army has come along and they have taken the same technology as the Navy, the water cooled reactor.

light water reactor. He didn't like the fact that it had to run at really high pressure.

The liquid fluoride thorium reactor.

Reactor breach in 3 minutes!

Lock on to their reactor.

They've taken the reactor offline.

The reactor could melt down.

Ahsoka, we're in the reactor

it's from that reactor wall.

The traveling wave reactor is another form of a liquid metal fast breeder reactor.

So traditional reactors like a pressurized water reactor or boiling water reactor, they're very, very hot water at very high pressures, and this means, essentially, in the event of an accident, if you had any kind of breach of this stainless steel pressure vessel, the coolant would leave the core.
