New form of Energy for Capetown 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, with 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 k Wh, with is 2550 k Wh less than the energy consumption per inhabit a year in Paris, France. Our plan is to built the most effective, cheap also 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: 3 Coal power plants or 12 Hydro power plants or 7 Gas turbine power plants or 173 Solar power plants or 4792 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: A nuclear power plant may sound nasty and dangerous, from the naturist ic 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, with is about one van of uranium per year, but a coal power plant with same capacity needs about 140 tons of coal per hour, and it also po lutes the air by carbon dioxide with is released when coal's stored energy is been transformed into heat energy. The carbon dioxide with is been released in the process causes greenhouse effect, with is the main cause of increased temperature of world. A hydro power plant does not need fuel, but it po lutes 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 bio system 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, even one turbine needs about 100 x 100 m 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 po lutes the, The turbines also cause some problems in TV and radio links.

Solar power pant is also a good solution because it does not really pollute the air, but the problem with it is the space that it requires to produce the amount of energy that we need, for example a solar plant wit capacity of 10 MW needs a space of 53 x a soccer play ground, and huge amount of concrete, glass and metals is needed to built to plant. The problem with the gas turbines are the number of plants that we need, it also pollutes the air by the carbon dioxide and nitrogen oxides that it releases into the air. In the air the nitrogen oxide turns into nitric acid, with comes down to the ground with rain. Technological facts that concerned us: The reason we didnt choose solar power is because of the hard storing of the energy, and it cannot store energy for darker times, the efficiency rate of the plant is quite low also. The problem with wind power is also the efficiency rate, and the amount of turbine that we need is far too many, the wind is not all that well in Capetown because it is surrounded by mountains. Studying Nuclear power plant process?

This is a pressurized water reactor, and it is considered to be a basic type of nuclear rector es, and it is used commonly. the power of this particular plant is about 900 MW, and its efficiency ratio is about 33%. Nuclear energy is released in the reactor, when nuclei used as fuel in the reactor splits. Nuclear energy transfers into heat energy, with heats up the water. the hot water turned into steam, with, will flow to the turbines. The turbine spins the generator, with will produce electricity. The electricity is then sent to be formed in a sell able form.

Then the steam is sent to cool, and then it comes back into the reactor. Fuel used in this process is rich ed Uranium with is bought from France. The waste with is produced will be trans feed to the deep mind in South Africa. The transportation will happen by IVO power company from Finland.
