1 Nuclear Technology In-class Essay Friday!!!!! Bring an index card and your works cited page.

2 Example:Nuclear Power Plants Research (take notes in my own words):  Energy produced through fission reactions A neutron splits a large unstable atom like U-235 *More neutrons, 2 smaller nuclei and energy (kinetic and gamma) are produced (E=mc 2)

3 Research: continued  High energy neutrons produced from 1 st fission reaction can split more U-235 atoms, making a chain reaction  Moderators made of smaller atoms slow down the neutrons (by absorbing some of their energy as they pass through) – this prevents the fission reaction from getting out of control (meltdown)

4 Research: continued  Manual or automated controls stop the fission reaction if unsafe conditions are detected  Energy produced during fission is converted into electrical energy

5 Research: Dangers  Accidents release radioactive energy, creating a dangerous environment (Chernobyl and Three Mile Island Disasters)  Waste from fission reactions are difficult to store  Fears of nuclear proliferation (the spread of nuclear weapon capabilities

6 Research: Benefits  Reduces carbon emissions that may lead to global warming  Decreases our dependence on foreign oil  Safety record is good compared to power plants fueled by other sources  Reprocessing of spent nuclear fuel removes a lot of the nuclear waste

7 Your argument will be stronger if you also collect quantitative data: If you are arguing for benefits… If you are arguing for risks…

8 Organization Begin with your thesis statement: Are you for or against the use of nuclear technology? You can organize the body one of two ways: Discuss the benefits and risks of 3 different kinds of technology (pro but con, pro but con, pro but con) Example: 1) Nuclear power plants benefits and risks 2) PET scans benefits and risks 3) Nuclear Technology in the home benefits and risks Or…

9 Discuss the benefits all together (separately from the risks) and the risks all together (pro and pro and pro, but con and con and con) Example: 1)Nuclear power plants, treatment of cancer, and using half-life to date benefits 2)Nuclear power plants, nuclear weapons proliferation, and irradiation of food risks

10 When writing about each benefit or risk, use the PEA format:  P=point (keyword, definition, topic sentence of a paragraph) Example: Nuclear power plants use the process of fission to produce a cleaner form of energy than fossil fuels. Example: Nuclear power plants use the process of fission to produce a cleaner form of energy than fossil fuels. E=evidence (an explanation of and/or example of the point. This is where you elaborate on the point) Example: Describe the differences between nuclear power plant emissions/waste and the emissions/waste produced from power plants that use fossil fuels. Provide quantitative (numerical) data on the differences in emission/waste output.

11  A=analysis (elaborate on the evidence. Explain how it supports the thesis) Example: Explain if the differences in emissions/waste are significant, making nuclear power beneficial. Could nuclear power help alleviate problems like global warming and pollution? Example: Explain if the differences in emissions/waste are significant, making nuclear power beneficial. Could nuclear power help alleviate problems like global warming and pollution? Now I would move on to discuss a risk related to nuclear power plants, using PEA Any questions?
