Nuclear Power Plants' Effects on the Environment (Essay Sample)
Read this essay on nuclear power plant to learn about Nuclear Power. After reading this essay you will learn about: 1. What is Nuclear Power? Sources of Nuclear Power 3. Generation 4. Scope 5. Advantages 6. The smallest indivisible part of any matter which maintains its properties was called an atom. The central part of an atom is its nucleus. Electrons rotate around the nucleus which carries protons and neutrons. If the structure of atom can be changed, huge amount of power can be harnessed. This is nuclear power. Both processes can produce huge energy. This atomic energy is converted to electrical energy for proper use or heat energy for improper use —the atom bomb.
Major sources of nuclear power are Plutonium, Uranium, Thorium, Barium, Zircon, Ilmenite, Monazite etc. Total recoverable uranium reserve of the world is 2, thousand metric tons only. Australia possesses largest reserve, thousand tonsfollowed by Canada thousand tonsU. Africa thousand tonsNiger thousand tonsBrazil thousand tonsUkraine thousand tons. Apart from these countries, significant deposits are found in countries like Namibia, France, Portugal, Gabon, Spain, Mexico, Turkey etc. Uranium varies widely, according to its molecular weight. There are three varieties of isotopes found on earth — UraniumUranium and Uranium Thorium is generally extracted from Monazite sands. Australia, Brazil, Nigeria, U. and Canada are principal producers of Thorium. Kerala coast in India is also a significant producer of Monazite sand.
Nuclear reactors permit chain reaction under controlled conditions. Uncontrolled chain reactions produce atomic bombs — first produced in U. in and exploded experimentally in New Mexico on Hiroshima-Nagasaki. The first nuclear reactor in the world was established in at Calder Hall, Britain. Since then, setting up of nuclear reactors remain unabated all over U. Till now, Britain has 35 nuclear reactors, while U. has more than reactors — securing first position in nuclear power generation. Since the installation of first nuclear reactor in Calder Hall, Britain, inthe crisis — reeled energy scenario of the world accepted nuclear power as panacea or problem — solving weapon to combat energy shortage.
But this euphoria did not last long. It failed miserably to deliver the desired results. Inthe electricity produced from nuclear source was 2, thousand million K. hours while contribution from thermal and hydro-electricity was 8, thousand and 2, thousand million K. hours, respectively. The Three Miles Island U. The N. Nuclear Proliferation Treaty and international monitoring system on nuclear reactors, different political pressures and growing resistance from environmentalists are the reasons liable for slow growth of nuclear power. There is very little scope to increase nuclear power use in the coming years. According to estimates, essay on nuclear power plant, byalmost all the large on-going nuclear power projects will be completed.
If the present consumption rate continues unabated, the existing uranium reserves of the world will last for only 40 years, essay on nuclear power plant. Most of the old uranium mines were closed essay on nuclear power plant to depletion of reserve. Existing mines will not last more than 40 years. So, future of nuclear energy, as a source of energy, does not remain very bright. No other source of energy can produce such amount of power from so small quantity of material. It has been estimated essay on nuclear power plant only 1 tonne of uranium produces energy equivalent to the energy produced by 5 million tons of coal!
Sophisticated machines can use nuclear power easily. This does not require cumbersome engines or boilers. High power submarines, specially designed ice-breakers and ships use nuclear power without much trouble. The heat produced by the nuclear reaction is taken to steam-raising boilers and the high-pressure steam is led to turbines which drive the electric generators. Though installation cost is very high, operative cost and per unit energy production cost and other recurring expenses are very low in nuclear power.
Nuclear power is cost-effective only when the plant is fully operative. In most of the cases, fossil fuels like coal and petroleum are easily available and prices are comparatively not very high, so nuclear power is not advantageous. Nuclear power generation and its waste disposal is considered to be one of the greatest threat to the environment. Environmentalists are raising their protests against the setting up of nuclear power projects. The Three Miles Island and Chernobyl disasters in U. and former U. has proved their apprehensions about the danger of nuclear radiation effect on the human health. Nuclear submarines about lying essay on nuclear power plant in Russia are proving dangerous as the sea is being contaminated with radioactivity.
This proves threatening to Norway, Sweden and other nearby countries too. Besides essay on nuclear power plant danger to environment, essay on nuclear power plant, development of nuclear power, as viewed by one section of people, is unethical as it is leading to the development of nuclear arms race, which, in turn, will endanger the essay on nuclear power plant species in the world! Nuclear technology is confined only to few developed countries. Research and development of nuclear technology is very expensive and complicated. Huge investment in this field will certainly deprive investments in more essay on nuclear power plant fields — agriculture, basic health, education etc.
Nuclear power requires radioactive fuel like Plutonium, Uranium, Thorium etc. These ores are found only in some countries. Countries like India, deficient in Uranium reserve, rely more on import. Relation, mostly political relation, if deteriorated with exporting countries may stop supply of uranium etc. and running of the plant becomes very difficult. Following the stoppage of uranium supply to Tarapur plant in India by France, essay on nuclear power plant, Australia and U. deadlock situation occurred. Nuclear Proliferation TreatyC. Comprehensive Test Ban Treaty etc. made further nuclear research in developing countries like India very difficult, essay on nuclear power plant.
