  2. What is Nuclear Power? Zach Dahl • Nuclear Power is produced from a chain reaction starting with nuclear fission • Nuclear Fission: The splitting of a nucleus into smaller nuclei • http://www.youtube.com/watch?v=xVSq_LUv3ns

  3. Historical Context • 1957- • The International Atomic Energy Agency (IAEA) was formed with 18 member countries to promote peaceful uses of nuclear energy and to prevent the spread of nuclear weapons. Shelby Lehr • 1983 - • The Nuclear Waste Policy Act of 1982 was signed, approving the development of a high-level nuclear waste repository.

  4. 1979 - Three Mile Island Meltdown Shelby Lehr The accident at the Three Mile Island Unit 2 (TMI-2) nuclear power plant near Middletown, Pennsylvania, on March 28, 1979, was the most serious in the U.S. nuclear power plant industry's operating history. Equipment malfunctions, design-related problems, and human error led to led to a partial meltdown of the TMI-2 reactor core but only very minute releases of radioactivity. Although no deaths or injuries resulted, the accident brought about sweeping changes in emergency response planning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. These changes enhanced the safety of the industry.

  5. 1986 - Chernobyl, Ukraine 1986 • The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. • The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the atmosphere and downwind. • Two Chernobyl plant workers died on the night of the accident, and a further 28 people died within a few weeks as a result of acute radiation poisoning. • UNSCEAR says that apart from increased thyroid cancers, "there is no evidence of a major public health impact attributable to radiation exposure 20 years after the accident." • Resettlement of areas from which people were relocated is ongoing.

  6. Geographical Context Shelby Lehr

  7. Nuclear Plants in the U.S.

  8. Major Players Dragana Petic • IAEA • Responsible for monitoring the world’s nuclear facilities and for preventing weapon increase • Safeguards have serious shortcomings • Cannot detect all possible diversions of nuclear material

  9. Sources of Conflict Dragana Petic • About 18 lbs of plutonium-make one Nagasaki type bomb • In 2000 620,000 lbs produced. Enough to create 34,000 nuclear weapons • Accidents

  10. Sources of Conflict Dragana Petic • Nuclear waste • 3 ways nuclear waste produced • Produced in reactor core • Result of radioactive contamination • Produced as a byproduct of uranium mining, refining, and enrichment. • Majority of radiation given off is from spent fuel rods

  11. Impact on U.S. Zach Dahl • We are the world’s largest Nuclear power producer • 30%+ of the worlds nuclear energy • Currently there are 104 Nuclear Power Plants • Many more are in the process of development Local One Power Plant currently located in Palo, Iowa

  12. Impact on U.S. Zach Dahl • Energy demand is expected to increase 25-50% • Government laws are now making it easier for nuclear energy to be used

  13. New Reactors • Because of how efficient Nuclear energy processing is, a boost in power plant building is expected in the next 20 years • 60% more efficient than gas or coal plants • The NRC (Nuclear Regulatory Commission) is currently trying to get 20 new reactor sites.

  14. Solutions Hailey Schiller • Minimize radioactive exposure • Keep track of how much is being put out • Meet today’s regulatory requirements • Have regular check ups to make sure everything is running correctly
