Nuclear Energy By: Abby Bruce, Rio Chamberlain, Hannah Hauck, and Brenna Usry

Scientist  Uranium is the main source of power.  Concentrate and purify Uranium to get a purer nuclear fuel.  Uranium is more abundant than gold and silver, same natural resources as tin.  Byproduct of copper mining and contained in gold ore.  Low concentrations but large amounts of Uranium in ocean overall.  Safety precautions such as dust suppression and remote mining.  Fission vs. Combustion  Pressurized Water Reactor: Needs Steam Generator  Boiling Water Reactor: Steam generated by Fission  High Level Radioactive Waste  Low Level Radioactive Waste  Nuclear power plant can be built anywhere.  The only region-specific issue is the mining of Uranium

Economist  Capital cost, high, 2.5 billion dollars.  Plant operation costs are moderate.  External Costs, cost to society  Low fuel cost  High return  22 tons of Uranium used saves 1 million tons of CO 2 emissions from coal plants.  Inexpensive to run and creates jobs.

Economist: When a Nuclear Plant Spends $1…  $1.04 into local economy  $1.18 into state economy  $1.87 into U.S. economy  Nuclear Plant on average spends $16 million in state and local taxes annually.  $67 million federal taxes annually.

Environmentalist  Wastes produced include low-level and high-level radioactive waste.  No carbon dioxide, sulfur dioxide, or nitrogen oxides are produced from the nuclear power plant process. CO 2 is only released during the mining of uranium.  Habitats are only altered/disrupted by thermal pollution from the heated water from the reactor being dumped back into the body of water it came from, by the mining of the uranium, and by the construction of the power plant itself even though moderate space is needed.  Threats to human health: nuclear power plant malfunction/meltdown which releases dangerous radiation, leakage of nuclear wastes if not properly maintained and/or disposed of, and from mining of the uranium

Historian/Sociologist  Controversial subject with some for and against nuclear as major energy source.  1789 Martin Klaproth discovers Uranium  1895 Wilhelm Rontgen discovers Ionization Energy  1938 Hahn and Strassmann discover fission  Most people do not want to live near the hazard of a Nuclear Power Plant.
