How they work.

Nuclear Energy is created in nuclear plants with use of the element U-235, or Uranium 235 in the form of pellets.  The pellets are submerged in water inside a pressure vessel.  The water is used as a coolant.  In order for the reaction to take place the uranium must become slightly super critical.  When it is supercritical this means that if it was to stay in there without the watch of a person, it would melt.  

 

To prevent the uranium from melting there are control rods that absorb neutrons.  This allows the operator to control how much nuclear reaction goes on inside the reactor.  This allows the operator to control how much heat the reaction creates. 

 

In side of a nuclear power plant a neutron is shot at a U-235 atom. The neutron causes the nucleolus of the atom to split.  When this happens a large amount of energy and radiation is released.  Once the first nucleolus is split it starts a chain reaction. 

 

The reaction causes steam.  Just like with the fossil fuels steam rotates the rotor, and the current gets taken by the copper wire.. 

 
 
Pros of Nuclear Energy
 
    • The supply of uranium could last for the next century. 
    • Power plants are becoming more reliable.
    • Large amount of energy is produced through fission. 

  Cons of Nuclear Energy

    • Radioactivity is dangerous for workers, and people. 
    • Not renewable, and we will run out. 
    • Nuclear waste has to be stored for 1,000 years, until it is safe, and stable. 
    • The cost for uranium is rising.
