The fuel, like I said, is ceramic inside zirconium fuel rods, and in the event of an accident in one of these type of reactors,

To the reactor?

Then what happens to the waste?

Reactor bay.

SHOUTlNG ADRlAN (VOlCEOVER) This was the scene inside the Unit One

This was the scene inside the Unit 1 reactor building after it was rocked by explosions.

LFTR is a molten salt reactor. All LFTRs are molten salt reactors but not all molten salt reactors are LFTRs.

The reactor is close.

And what about the nuc nucular reactor in Florida?

Big pipes.

And this is what it is.

Reactor, that's right.

Gunderson. He has over 40 years of nuclear power engineering experience. And Arnie holds a nuclear safety patent.

We haven't even started the American stockpile.

Seems a snail fell into a French nuclear reactor.

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

Okay, just tell me what happened.

I have some good friends in nuclear industry. They are very big advocates of the fast breeder reactor.

Ship. I'm on my way to the reactor.

Why would you want to go to the reactor?

One, it doesn't operate at high pressure.

So what they call Coulomb Barrier is reduced.

But the weight is different.

So I'm really excited.

The reactor is shutting down fast.

And number two, do not build a reformer on the ocean.

These are the reactors, very simple, you can see.

This is what drives the design of this building. If this happens, all the steam is captured in this building.

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

And that something we make might decay quickly. And if it was really absorptive and it decayed quickly, the reactor would do... this!

How long do you think that reactor has been sitting there, huh?

This is the shape of Tokamak, a torus reactor.

Listen, if you can get me to the reactor bay

The cause of the accident is unknown.

But I know everything there is to know about that damn reactor.

What's your plan?

And then we get to uranium.

Heat was not being removed from the 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.

This has a distinction of being the newest nuclear reactor in the United States. This came online in 1996.

That decay heat continued to build.

Just crazy, I mean, these guys didn't even know what xenon 135 was, because this was one of the first nuclear reactors ever built.

They shut down the reactors.

Reactor timing is offset in the core.

Its volume increases roughly by a factor of 1000.
