  1. Nuclear Reactors By Ethan Campbell, Garrett Dodson, and Kyle Ribble

  2. Containment Structure A containment building, in its most common usage, is a reinforced steel or lead structure enclosing a nuclear reactor. In case of nuclear failure, the containment structure will hold the radiation and pressure in, saving lives and time.

  3. Control Rods A control rod is a rod used in nuclear reactors to control the rate of fission of uranium and plutonium.

  4. Reactor The reactor is the main part of the power plant. Neutrons are shot at Uranium to produces a lot of heat, which boils water to drive a turbine.

  5. Steam Generator The steam generator converts the water into steam through heating tubes that siphon the heat off of the reactor. This steam drives the

  6. Turbine Device that extracts thermal energy from pressurized steam and uses it to do mechanical work.

  7. Fuel Rods A rod composed of uranium, mixed with structural, neutron moderating, or neutron reflecting materials.

  8. Condenser A device used to condense vapor into liquid.

  10. How is the nuclear reactor self-sustaining? A nuclear reactor is self-sustaining due to the chain reaction. Neutrons produced from one reaction can hit other isotopes to start a new fission reaction.

  11. Pros of a nuclear power plant • Pollution - A nuclear power plant is %100 clean, releasing no carbon dioxide into the atmosphere. • Economic improvement - If developing countries adopt the idea of nuclear power plants, then that nation's economy will overall improve by creating new jobs and selling the energy made. • Cost to build and maintain - The cost to build a plant ranges in the billions, but the cost to maintain a plant is relatively cheap. So in the long run the plant will eventually pay itself off by making clean energy. • Greenhouse gas emissions - A nuclear power plant releases steam, so it doesn't emit any greenhouse gas. • Fuel Cost - The cost and power of Uranium is by far cheaper and more powerful than oil or coal.

  12. Cons of a nuclear power plant • Potential accidents - Use of concrete structures (Three mile island & Chernobyl) or hazardous water leaking out of the plant. • Security risks - People stealing radioactive material to make a “dirty bomb,” although the chance of that happening is slim. • Waste disposal - it takes thousands of years for nuclear waste to decompose and although people are fixing the problem the public still finds nuclear waste hazardous because of the radioactive aspect. • Reaction temperature - There is no limit to how hot the reaction can get, ultimately resulting in a nuclear meltdown if it is not cooled. • Location - Location of power plants need to be away from populated areas, so finding workers willing to drive and work at a distant place is a hard task.
