Nuclear Power Plant :: essays research papers

New form of Energy for Capetown   Ã‚  Ã‚  Ã‚  Ã‚  Capetown is considered to be the largest city in South Africa, having a population of over 2,727,000 inhabits. The energy form used in Capetown at the moment, is Gas Turbine, wich provides most of the city ´s electricity. The use of electricity in Capetown is very low compared to western countries, for example there is only one TV for almost ten people, the energy consumption per inhabit a year is about 4000 kWh, wich is 2550 kWh less than the energy consumption per inhabit a year in Paris, France.   Ã‚  Ã‚  Ã‚  Ã‚  Our plan is to built the most effective, cheap also inviromentaly friendliest way to produce energy for the 1 575 000 inhabits of Capetown, we came to the solution: BUILT A NUCLEAR POWER PLANT. ? Picture of Loviisa, Nuclear power plant We explain our solution by the following facts: ? If we built other forms of plants we would need:   Ã‚  Ã‚  Ã‚  Ã‚  3  Ã‚  Ã‚  Ã‚  Ã‚  Coal power plants or   Ã‚  Ã‚  Ã‚  Ã‚  12  Ã‚  Ã‚  Ã‚  Ã‚  Hydro power plants or   Ã‚  Ã‚  Ã‚  Ã‚  7  Ã‚  Ã‚  Ã‚  Ã‚  Gas turbine power plants or   Ã‚  Ã‚  Ã‚  Ã‚  173  Ã‚  Ã‚  Ã‚  Ã‚  Solar power plants or   Ã‚  Ã‚  Ã‚  Ã‚  4792  Ã‚  Ã‚  Ã‚  Ã‚  Wind power plants. but we only need one nuclear power plant to provide enough electricity for 1 575 000 people. Inviromental facts that concerned us:   Ã‚  Ã‚  Ã‚  Ã‚  A nuclear power plant may sound nasty and dangerous, from the naturistic point of view, but that is not a fact. A very good example of this is, the amount of fuel that a 900 MW nuclear power plant needs, wich is about one van of uranium per year, but a coal   Ã‚  Ã‚  Ã‚  Ã‚  power plant with same capacity needs about 140 tons of coal per hour, and it also polutes the air by carbon dioxide wich is released when coal’s stored energy is been transformed into heat energy. The carbon dioxide wich is been released in the prosess causes greenhouse effect, wich is the main cause of increased temperature of world. A hydro power plant does not need fuel, but it polutes the sights of a beautiful current river, because of it size, sometimes whole villages have to be moved from the reservoir area, it also effects the biosystem of both up-and down stream for quite a long distance from the location of the dam. A wind power plant is a good solution but it needs space, ev en one turbine needs about 100x100m space to work properly, if a malfunction appears in the turbine, it can fall down or the blades might break, and fly for thousands of meters. The industry producing the turbines polutes the inviroment, The turbines also cause some problems in TV and radio links.
