FC: NUCLEAR ENERGY | By: Daphne Zhuang 7D
1: Nuclear power is an energy source that can provide energy to lots of people. | Nuclear energy comes from the famous Einstein formula, E=mc2 | WHAT IS NUCLEAR POWER? | Nuclear power comes from nuclear power plants. | Nuclear energy is a way of creating heat
2: How a Nuclear Power Plant Works | Nuclear power plants run on uranium | The uranium is not burned; instead it is "fissioned" or split up | Fissioning uranium creates heat | Electrical power = energy for people
3: Pickering | Nuclear Power Plants | Located at the north side of Lake Ontario in Pickering, Ontario | Has six reactors | Total output of 3,100 megawatts | Enough to support a city of one and a half million people!
4: Short Term Effects | Radiation | Destroying animal homes | Radiation that spreads through neighborhoods and cities nearby | Nuclear power plants need 81 - 162 hectares of land | Killing plants and trees | By clearing land for nuclear power plants
5: Long Term Effects | Skin cancer | Cancer | Run out of room to store nuclear waste
6: Affecting Wildlife and People | Nuclear power plants destroy habitats for nearby animals and plants by taking up space | Radiation may spread through neighborhoods and cities | Animals like pigs and cows that became beef later on will have to be thrown away because of radiation that may be contained inside the meat
7: THE SAFE SIDE OF NUCLEAR ENERGY | Can be safely stored - buried under the seabed of a ocean | This way, high level nuclear waste can be stored under the sea for a long time | Can be blasted off into space | Can be buried deep inside Yucca Mountain | Spent fuel rods can be stored in dry cast containers | High Level waste...
8: Can be kept in low level nuclear waste dumps | Low level nuclear waste dumps are places with trenches where the nuclear waste will be stored, then covered with dirt | Low Level Waste... | THE SAFE SIDE OF NUCLEAR ENERGY | Radiation... | Can be safely contained in two ways: | stored in ceramic pellets in long metal rods | or | inside a reactor vessel, encased in a concrete and steel building with walls 3 - 5 feet thick
9: Radiation spreading through nearby cities: | The chance of a nuclear power plant meltdown: | Two used fuel rods placed a little too close together: | The Not So Safe Side of Nuclear Energy | Yup. That happened. Look at the accident at Goiania in 1987. | Yep, that happened before too. See the meltdown at Chernobyl in 1986. | Okay, so this didn't happen to any nuclear power plant but you'll never know when somebody accidentally places them too close together!
10: The Not So Safe Side of Nuclear Energy | Yes, it can be stored under the ocean, but what happens if the ocean blows up? | High level nuclear waste can be blasted off into space, but it is: | Expensive | Dangerous, because there may be the risk of blasting the nuclear waste into the wrong orbit | After storing waste in Yucca mountain and in dry cast storage containers, there may be not enough space to store more waste.
11: The Not So Safe Side of Nuclear Energy | That's right! Spent fuel rods can be stored in dry cast storage containers. | But have you ever thought what would happen if we run out of space inside dry cast containers? | Where would all the spent fuel rods go? | We cannot continue on and build MORE dry cast storage containers!
12: The Not So Safe Side of Nuclear Energy | Low level nuclear waste can be stored in low level nuclear waste dumps. | But what will happen when the nuclear waste dumps start to overflow? | Where would we put the low level nuclear waste? | Nuclear waste dumps are like garbage dumps, except that nuclear waste takes even longer to become safe! | Yes, radiation can be contained, but there is never 100% when it comes to safety! | For example, you may never know when your house may collapse even though it is very protective!
13: Nuclear Power | So... | is Not the most safest way to generate energy. | Therefore, nuclear power should not be used!
14: Fukushima Nuclear Power Plant Crisis | The magnitude 9 earthquake knocked out the electricity at Fukushima No. 1 power station | Backup generators prevented the fuel rods from overheating | Generators worked, but the tsunami damaged them | Workers attempted to install mobile battery power units but was not enough to cool all the reactors | The building exploded because the attempt to cool the No. 1 reactor failed
15: Interesting Facts | Nuclear material can be used to find and treat certain illnesses | Nuclear energy can be used to make research at universities | Nuclear energy helps industries find things like: | Cracks in steel | Ridding film of dust | Measuring amount of air being whipped into ice cream | One tone of uranium makes more energy than one million tons of coal
