Nuclear Fission Fusion

Isotopes of Uranium

There are three isotopes of Uranium. They consist of:

  1. U-235
  2. U-238
  3. U-234

Half Life of the Isotopes of Uranium

The three isotopes of Uranium have the half lives of:

  1. U-235- 700 million years
  2. U-238- 4.47 billion years
  3. U-234- 246 thousand years

The percent of each Uranium isotope that exist in nature.

The percent of each Uranium isotope that exist nature:

  1. U-235- 0.72%
  2. U-238- 99.27%
  3. U-234- 0.0055%

Induced Fusion

Induced Fusion is the use of slow paced thermal neutrons to eliminate heavy nuclides.

Critical Mass

Critical mass is the amount of material that is required in order to create a chain reaction that is self sustaining.

Chain Reaction

A nuclear chemical chain reaction is when a neutron bombards a nucleus and then other neutrons fall off of the nucleus and then go on to bombard other nuclei and knocking off more neutrons and so on.

Fusion Process

The process of fusion is when two light nuclei are put under so much pressure that they combine to form one nucleus that is heavier than the light nuclei.

Fusion fuels

Fusion fuels have a high abundance and examples of this are:

  1. Deuterium
  2. Tritium

Advantages of using fusion and fission

Some advantages of using fusion and fission are:

  • Fission and Fusion create much more energy than alternative sources of energy.
  • The cost of electricity when using fusion or fission are much cheaper than what the cost would be with other sources of energy.

Major obstacles to overcome

Major obstacles that Fusion need's to overcome to become a large scale energy source are:

  • Finding a way that enough heat can be created to create and sustain fusion.
  • Making fusion more efficient in terms of energy production than fission.
  • Lowering the price of creating energy.

Scale that fusion is being completed in today's world.

The scale that fusion is being completed in today's world is small. There are few power plants that can acquire enough heat to force fusion. There are some power plants that can produce enough heat which is required to create fusion. In Japan A fusion reactor called the JT-60 has the highest triple fusion product value.
