 * 1)  First, uranium fuel is loaded up into the reactor—a giant concrete dome that's reinforced in case it explodes. In the heart of the reactor (the core), atoms split apart and release heat energy, producing neutrons and splitting other atoms in a chain reaction.
 * 2)  Control rods made of materials such as cadmium and boron can be raised or lowered into the reactor to soak up neutrons and slow down or speed up the chain reaction.
 * 3)  Water is pumped through the reactor to collect the heat energy that the chain reaction produces. It constantly flows around a closed loop linking the reactor with a heat exchanger.
 * 4)  Inside the heat exchanger, the water from the reactor gives up its energy to cooler water flowing in another closed loop, turning it into steam. Using two unconnected loops of water and the heat exchanger helps to keep water contaminated with radioactivity safely contained in one place and well away from most of the equipment in the plant.
 * 5)  The steam from the heat exchanger is piped to a turbine. As the steam blows past the turbine's vanes, they spin around at high speed.
 * 6)  The spinning turbine is connected to an electricity generator and makes that spin too.
 * 7)  The generator produces electricity that flows out to the power grid—and to our homes, shops, offices, and factories.

Brandon:Everyday Uses

Nuclear power is produced when nuclear fission occurs, breaking one nuclei into two seperate nuclei. The resulting heat from this reaction is used to boil water to produce steam to run a steam turbine, which generates electricity. In 2009, 13–14% of the world's electricity came from nuclear power

Nuclear fusion reactions have the potential to be safer and generate less radioactive waste than fission.These reactions appear potentially viable, though technically quite difficult and have yet to be created on a scale that could be used in a functional power plant.Fusion power has been under intense theoretical and experimental investigation since the 1950s.

There is a differing of opinion among scientists over the effects caused by constant low levels of radiation. Various scientific studies have shown an increased rate of cancer among people who live near nuclear power plants. Long term exposure to low level radiation has shown to damage DNA. The degree of damage caused by low levels of radiation to wildlife, plants and the ozone layer is not fully understood. More research is being done to determine the magnitude of effects caused by low levels of radiation in the environment.

Benefits
 One of the main benefits is that nuclear plants emit no CO2 or pollution into the air. Uranium that has gone through fission also lasts about three years before new uranium is needed in each section of the reactor. This helps the element last longer because it is nonrenewable.

Harms
 All of the water that is steamed to power the turbines becomes radioactive and this can be harmful to humans. The process of creating nuclear energy also creates nuclear waste that needs to be stored. If it is not properly stored then radiation can spread, causing harm to living things, mutations and potentially death.
