Nuclear Fusion

Kaleb Hente and Denny Ponte


The fusing of two or more lighter atoms into one larger one.


The Fusion itself is inexhaustible, composed of hydrogen isotopes (Deuterium and Tritium)

How it Works

Reaction is caused by nucleosynthesis transmutes atomic nucluei, atoms (usually hydrogen) smashing together and releases energy in reaction.

Discovered and first used

-Fusion energy was first discovered in the 1930's, by Hans Bethe in Cambridge, England.
-First ever used by stars
-First used by humans in creating the Hydrogen bomb.

Where and how it is used today

-Used by the EU, USA, Russia, and Japan.
-Underway by China, Brazil, Canada, and Korea.
Currently used in bombs.
Used to power grids and cities in future.


"I would like nuclear fusion to become a practical power source. it would provide an inexhaustible supply of energy, without pollution or global warming."

-Stephen Hawking

"I really have become convinced that nuclear fusion is our energy future. It's so powerful. I mean, it is the power of the stars. If we could bring that down to the laboratory and to the power plant of Earth, that would be and incredible thing."
-Taylor Wilson

"Watching cold fusion is like watching water boil in slow motion. First, sufficient deuterium has to penetrate the palladium electrode. This can take a few weeks. Then, if excess heat is generated during the next month or two, accurate temperature readings require extreme precautions to exclude environmental effects."
-Charles Platt


How do charged particles escape from the magnetic field?

-The turbulence of racing particles reach to the plasma edge in just one second.

How is plasma contained?
-good insulation from the material surfaces allows low density of plasma to be heated to the very high temperatures required for fusion.

How are high temperatures achieved?
-Good insulation, the application of high power leads to a temperature above 100 milion degrees celsius.

Are all fuel costs significant?
-The fuel would contribute much less than 1% to the cost of electricity.

What are the dominant costs foreseen in a fusion power plant?
-The superconducting magnets and the mere structure of the plant itself serve as the dominant costs for a fusion power plant.

Pros and cons

-Clean energy.
-Virtually limitless fuel available.
-No chain reaction.
-Little or no nuclear waste.
- Very low fuel costs.
-No full scale production till about 2050
-Very high temperatures which are hard to contain
-Commercial power plants are expensive
-Could produce a net negative amount of energy


Production costs are almost the same as fission plants. The fusion plant would use a lot more energy to be stable.
