  • Energy is the ability to do work.
  • Work is the movement of something when an effort is applied.
  • Atoms are the smallest building blocks of matter.
  • Matter is anything that has mass and takes up space.
  • An atom consists of a Nucleus that contains Protons and Neutrons which is surrounded by Electrons

    Nuclear Reaction is the reaction that changes the nucleus of an atom.

  • Nuclear energy is a clean energy source in terms of carbon emissions released.
  • Nuclear energy is a reliable source of power because the nuclear reactors used today have a pretty long life (they work for decades).
  • Nuclear energy is a very powerful source of power which is also efficient (nuclear power has the highest energy density known by man).
  • A nuclear power plant generates huge amount of clean electricity in a pretty small space.

  • Nuclear power produces nuclear waste that is very hazardous for the environment and for any living being.
  • Nuclear power is not a renewable energy source because uranium, plutonium and thorium are finite resources.
  • Disposing nuclear waste is a very expensive activity that requires both high expenses and heavy military guard for the objective.
  • Nuclear power has already produced several radioactive disasters that affected both human life and the environment.

The heat it produces is used to boil water to make steam, which drives one or more giant steam turbines connected to generators—and those produce the electricity we're after. Here's how:

    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 carefully controlled nuclear 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.
