“Little Boy”

Inside the little guy … Inside the little guy …

Hiroshima

PAYLOADS  TYPICAL ATOMIC BOMBS HAVE PAYLOADS 10 KILOTONS  THAT IS THE SAME DESTRUCTIVE FORCE AS EXPLODING 10,000 TONS OF TNT!!!!

Nuclear Power Plants  Nuclear power plants use fission just like a nuclear or atomic bomb.  But in a power plant, the chain reactions are somewhat controlled.  How? Let’s look at a diagram of a nuclear reactor in a power plant…

Diagram of a power plant

Fuel rods  The uranium are first processed into small pellets about the size of a pencil eraser.  Then the pellets are placed into rods.

Fuel rods U-238 U-235

Can’t Explode  Nuclear power plants cannot explode like a nuclear bomb!

What about Chernobyl?

generator Core H2OH2O Heat exchanger steam

Was it a nuclear explosion? NO! IT WAS A PRESSURE EXPLOSION FROM THE STEAM!

Even if it did! Core Containment Dome

In Russia Core Containment Dome

In Russia Core

Control Rods  We can think of the control rods as neutron sponges.  If neutrons are stopped, the chain reaction stops

Fuel Rods

Control Rods

Cooling Towers  A cooling tower is a tall, hollow cylinder that is pinched a little at the top (those towers they feature on “The Simpsons” with the steam coming out of it).  The warm water from the reactor core must be cooled before releasing it to the environment to protect the wildlife.  Some of the water evaporates in the cooling tower, but most of it is recycled to be used in the reactor core once it is cooled.

Only steam is released! H2OH2O

Benefits of Nuclear Power  The power from one kilogram of uranium is equal to the power of 100,000 kilograms of oil.  No carbon dioxide emissions to contribute to the Greenhouse Effect  No sulfur emission to contribute to acid rain.  No need to use pipelines to transport gas and oil.

How much of the U.S. uses nuclear power?

FUSION TECNOLOGIES

FUSION  Joining nuclei of two atoms to form a heavier atom.  Extremely HIGH temperatures.  Hydrogen isotopes combine to form heavier elements and release energy.  Electrostatic repulsion between atoms must be overcome in order for fusion to happen.

Hydrogen Bomb

HYDROGEN BOMBS  MUST DETONATE ATOMIC (FISSION) BOMBS JUST TO GET THE REACTION TO OCCUR

PAYLOADS  TYPICAL PAYLOADS OF A HYDROGEN BOMB MEGATONS  THAT IS THE SAME DESTRUCTIVE FORCE AS 5 MILLION TONS OF TNT!!
