1: Nuclear Energy | Nuclear Energy The Good and Bad
2: Nuclear Energy is the energy released by a nuclear reaction or the splitting of atoms that generates heat | Alternative Source | A nuclear reactor uses uranium to boil water; steam rises up and moves turbines creating electricity
3: The process of creating nuclear energy! | Energy from uranium is released when a uranium nucleus splits and creates heat which makes steam; the steam generates movement in the turbines which then creates electricity!
4: Japan's Nuclear Power Plant
5: The nuclear reactor was unable to cool down which posed a risk of melting | Japan Earthquake March 11 2011
6: Low-Level Radiation | Water used to cool plants is now warmer than before and when it is returned to the ocean can affect ecosystems negatively | Short Term | Mining uranium which is to be used as fuel, emits large quantities of carbon dioxide; transporting radioactive waste also emits carbon dioxide. Low-level radiation is constantly given off by nuclear plants; it is proven that those near nuclear power plants are likely to get sick, and those near it long term can have damaged DNA
7: Emissions | Carb0on Dioxide | New Idea... New Risks.. | Fish are killed when we take water from oceans.
8: Uranium rods that are used have no place to be put so we store them in a hole in the ground which poses a risk of percolation and contamination. | Accidents and Attacks | Long Term Affects
9: If a power plant is attacked or has an accident everyone in the vicinity will be exposed to radiation... | Cooling Water System | Our ocean temperature is rising, because the water we return to it after we are done with it, is up to 25% warmer. This disrupts ecosystems and kills species.
10: Water used for cooling once returned to its origin is warmer and can disrupt the ecosystem... | The process of making nuclear energy does not emit harmful gases. | If a power plant has an accident or is attacked people will have exposure to radiation.
11: It is more eco-friendly than coal-burning. | Dependable and Efficient | Nuclear stations take up a small piece of land. | Wildlife and Me!
12: We are still only discovering this new method; we don't know many things like what to do with used uranium rods | There is a risk of civilians being exposed to radiation; it is not entirely environmentally friendly and there are unanswered questions still.... | Compared to coal burning and the use of fossil fuels, the best reliable yet Eco-friendly source of energy seems to be nuclear energy so far. | As we are still exploring this new form of energy, there are still many unanswered questions and therefore many risks involved.
14: Radiation levels were high after the incident. | A Catastrophe
15: There was a power increase in a reactor which caused a fire which increased radiation levels causing the disaster. | Japan and Chernobyl | The massive earthquake knocked out the power in Fukushima's power plant. The generators were then damaged by the tsunami. The power plant was unable to cool down its reactors. | Some pictures were to sad to put..
16: We do not know how to control nuclear energy and we are still discovering new things everyday.... | More eco-friendly than coal-burning but by far more riskier.. | There is a risk of leaching, some say.
17: When we make nuclear energy we are letting uranium nucleus separate setting off a atomic explosions which must be controlled. | We don't know what to do with uranium rods so we put them in the ground... | Water Contamination and Radiation Exposure
