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

If you hit it with a neutron, it's going to fission and split into two pieces, two fission products.

Well, lots of blue, because when you hit these dudes with neutron, you want them fission.

Neutron

Fission.

Now what these colors mean is the red means that it's going to absorb the neutron and the blue means that it's going to absorb the neutron and fission.

77,862 becomes cookie fission, cookie fission is 77,822.

On the other hand, you can fission it and then those fission products will decay very rapidly and you also get an energy release and a neutron release, both of which are good.

I want you to go back. Now I want you to hit it with a neutron and see if it will fission.

We have a neutron.

Look at plutonium, wow, big target, right? But one third of the time it's just going to eat the neutron in thermal fission.

lived transuranics through fission.

This is the smaller fission product and this is the larger fission product because each fission generates two of them.

Because I think it'll fission. I think it'll fission just like uranium 235.

So the we have the neutron.

And a neutron has no charge.

'Neutron Man' ... I can understand why.

That's what happens when the uranium absorbs the neutron and doesn't fission, and turns into plutonium, americium and curium and few other, most of it is plutonium.

Fission product gasses will accumulate here.

If you must know it's neutron damage.

So without the water the fission reaction stops.

Large uranium reserves for nuclear fission still exist.

One is the actual fission products that's what happens when you fission the stuff. Then there is what's called the transuranics.

Nuclear energy, fission, is really bad idea for bombs.

That seems right, I'll go on. Cookie fission, OK.

I have made something new. Thorium did absorb the neutron.

Well, you saw it yourself, standing in those neutron beams.

That's not good. On the other hand, in fast fission,

Let's talk a little bit about how nuclear fission works.

But if you hit the thorium with a neutron, the thorium will absorb the neutron and it will turn from thorium 232 into thorium 233.

But it will still be generating heat from those fission products.

Sure, we can alter elements by nuclear fusion or nuclear fission.

Doc, an invisible being that cannot be disintegrated by atomic fission.

Plasma of the neutron decays, and the outcome of the decay is...

When you fission a nucleus why is what you get out radioactive?

look at that, wow, was going to fission almost all the time.

Coming off discovering plutonium he thought, I wonder if we can hit thorium with a neutron and turn it into something. You got to remember, fission had been discovered three years earlier, so they were still in the very beginnings.

A neutron essentially turns into a proton and it spits out an electron.

This is fast energy, that means a neutron is still going really fast.

Nuclear fission is a million times more energy dense than a chemical reaction.

When you fission something, it breaks into these two pieces, but they're radioactive.

Some of these fission products have a really big propensity to eat neutrons.

Fission yields during development they were hoping to get clean bombs they didn't.

How much energy did the neutron have that you smack the nuclear fuel with?

Helium splits out, and a neutron comes out and lots of energy comes out.
