Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you would get from burning fossil fuels. Nuclear power costs about the same as coal, so it's not expensive to make. Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many thousands of years. For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult. Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. One of the most feared disadvantages of nuclear energy is the potential for weapons. Each year, every nuclear reactor is capable of making enough plutonium to build over thirty nuclear bombs. Nuclear plants must be secured well enough to prevent this material from falling into the wrong hands. ...
Nuclear Power: A Burden or a Blessing? Today, when the pollution of Earth is an important matter, people are trying to find economic solutions to produce power. This is where the necessity of nuclear power plants comes in question. Nuclear power plants are a cheap way to generate electricity but it also brings a lot of pollution that is much more radioactive and toxic than, for example, coal waste. But if we are looking at the facts, burning coal pollutes the Earth much more than nuclear power plants because more waste is generated. CO2, which is released from burning coal, is the main cause of global warming. Nuclear waste is collected and hidden in rocks or under ground, where it won't face the environment. However we shouldn't depend on nuclear energy as Uranium reserves are ending, especially when the world population is increasing and so is the demand for energy. There is Uranium in seawater, but gettin...
Argumentative presentation: Estonia does need a nuclear power station Good evening. My name is Margus and I will be talking to you about why does Estonia needs a nuclear power station. My talk consists of 3 parts: the current situation, renewables and how can nuclear power save Estonia from an energy crisis. My talk will last for 2-3 minutes and questions can be asked at the end. Power consumption is increasing exponentially in all civilised countries. Estonia's coal based power generation is becoming obsolete in the near future. The question arises : "Where will the future generations get the energy that they need?". First of all, in the current year, the power consumption reached the highest of all tomes in February. Most of the energy shortage was covered by energy brought from Lithuania. Energy was produced there from gas imported from Russia. That is not a reliable source of energy that can scale. In add...

Chernobyl disaster Outline • What happened? • Elimination of the consequences • The Exclusion Zone • Conclusion • Quiz • Reference list What happened? • The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR). An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe. • The Chernobyl disaster was the worst nuclear power plant accident in history in terms of cost and casualties, and is one of only two classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011). • The battle to contain the contamination and avert a greater catastrophe ultimately involved over...
The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the atmosphere and downwind. Two Chernobyl plant workers died on the night of the accident, and a further 28 people died within a few weeks as a result of acute radiation poisoning. The April 1986 disaster at the Chernobyl nuclear power plant in the Ukraine was the product of a flawed Soviet reactor design coupled with serious mistakes made by the plant operators. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture. The accident destroyed the Chernobyl 4 reactor, killing 30 operators and firemen within three months and several further deaths later. Acute radiation syndrome was originally diagnosed in 237 people on-site and involved with the clean-up. Of these, 28 people ...

Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos. Hydro-electricity has acquired great significance as a source of energy in the country in the present times and is being put to different uses. The following are the...

The Steam Engine By What are they? Steam engines are the first kind of engines to see a widespread use. They were used in the early locomotives, steam boats and factories. In fact they are still used to help run nuclear powerplants. When and by who were they invented and improved? The very first steam engine was built by Thomas Savery in 1698. However, it didn't turn any wheels, instead it pumped water out of coal mines. In 1712 Thomas Newcomen introduced an improved version of Savery's engine. James Watt improved it even further and later came up with an idea on how to use a steam engine to power something with wheels. Alright, but why are they important? Steam engines are veryveryvery important because it was the dominant source of power well into the 20th century. They actually were the moving force behind the Industrial Revolution. So no steam engines = no Industrial Revolution = Middle Ages that last approxima...
Dear Sir/Madam, I am writing in the hope that you can help me with a problem regarding a camera that I have bought recently. On 24 April, I purchased a Canon digital SLR camera from a duty-free shop at Freetown Airport on my way from Freetown to Wondercity. The camera cost $599, and I paid for it by credit card. When I arrived at my hotel in Wondercity almost 24 hours later, I discovered that the box which contained the camera did not include the battery, and the space in the box for the charger was empty. I am now in Wondercity, and I am not returning to Freetown, so I need to get the missing parts here. I would be grateful if you could arrange for the parts to be sent to me. I attach a copy of the receipt for your information. I look forward to hearing from you. Yours faithfully, Introduction This report looks at the dietary habits of twenty students in their final year at Freedonian Secondary School. The report is bas...
PENTAGON The Pentagon is the headquarters of the United States Department of Defense, located in Arlington County, Virginia. As a symbol of the U.S. military, "the Pentagon" is often used metonymically to refer to the Department of Defense rather than the building itself. Designed by the American architect George Bergstrom (1876 1955), and built by Philadelphia, Pennsylvania, general contractor John McShain, the building was dedicated on January 15, 1943, after ground was broken for construction on September 11, 1941. General Brehon Somervell provided the major motive power behind the project;[1] Colonel Leslie Groves (whose administrative ability, drive, and forcefulness led to his nomination to head the Manhattan Project in 1942) and Major Clarence Renshaw were responsible for overseeing the project for the Army. The Pentagon is the world's largest office building. It houses approxim...
Environment in Estonia Nowadays environmental problems are too big to be managed by individual persons or individual countries. In other words, it is an international problem. But what are the biggest problems in Estonia,why and how people could solve it? Air, water, and land pollution rank among Estonia's most significant environmental challenges. The combination of 300,000 tons of dust from the burning of oil shale by power plants in the northeast part of the country and airborne pollutants from industrial centers in Poland and Germany poses a significant hazard to Estonia's air quality. Estonia's water resources have been affected by agricultural and industrial pollutants, including petroleum products, which have also contaminated the nation's soil. Some rivers and lakes within the country have been found to contain toxic sediments in excess of 10 times the accepted level for safety...

The Crucial Problems of the World There are many problems in the world right at this time. One of the biggest and maybe the one which people talk about the most is the waste and recycling problem. As we all know, humankind is producing more waist than we can handle, reproduce and recycle. Even in here, Estonia, people are thinking of building a nuclear power station, because fossil fuel is soon depleted. The other problem, a little bit connected to the first one, is the greenhouse effect. The light from the Sun reaches us and after that the light reflexes from the Earth's surface back to the space, but thanks to the pollution, it absorbs and reflexes back to us again, causing global warming. The third problem is the fastly growing population. There are now more than 7 milliard people in the world and the number is still getting bigger. That leads us to the overcrowded cities, poverty and hunger. ...
Natural resources-our treasure Natural resources are land or raw materials like minerals, fluids, gases, organic matters and also woods, groundwater, animals and so on, in other words it's everything that human hasn't created. These resources are also used in industry. We get natural resources from the environment. Many of them are essential for our survival while others are used for satisfying our wants. Renewable resources: Some natural resources can be reproduced within a few years or decades. These are called renewable resources. Solar radiation, wind and hydroelectricity, are perpetual resources that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun...

Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan Causes · It is caused when sulfur dioxide and nitrogen oxides are released into the air. In the atmosphere they re...

Britain History Pre-Norman Britain The Iberians brought their metal-working skills and the first real civilization to Britain in the third millennium B.C and were overrun by various Celtic invasions that began in the 8th century. The Celts introduced their tribal organization and an early form of agriculture before they were forced westward by the Roman invasion. Forms of Celtic language are still spoken in Britain. Romans (with Julius Caesar in the head of them) first tried to occupy Britain in 55 B.C., but there was a rebellion in Gaul so they had to leave to fight against it. Next time they came in 43 A.D. and their leader was Emperor Claudius. Romans brought a lot with them. Their brought paved roads, the sites of important cities, the seeds of Christianity, the Roman law, Roman baths, language and advanced civilization. They also built Hadrian's Wall in 122 A.D.

BARRIERS TO DISTRICT HEATING DEVELOPMENT IN SOME EUROPEAN COUNTRIES Abstract District heating (DH) offers low primary energy demand, high security of supply and small CO 2 emissions. Barriers to DH in the UK, Ireland, France, Romania and the Czech Republic have been compiled through publications and interviews. DH systems require large investments, have negative initial cash flow and long payback time, which obstructs financing. One actor should control DH from source to consumption. If the value chain is fragmented, contracts are required between the links. It increases risks and financing costs, like in the UK and Ireland, where DH is not established. There are few multi- family houses with central heating and it is expensive to build DH networks in built areas. Most French DH systems are operated according to long-term concessions by companies that sell electricity and gas. No strong actor provid...

The Cataclysmic Death of Stars Republished from the pages of National Geographic magazine Written by Ron Cowen March 2007 Ever since he was a teenager, Stan Woosley has had a love for chemical elements and a fondness for blowing things up. Growing up in the late 1950s in Texas, "I did everything you could do with potassium nitrate, perchlorate, and permanganate, mixed with a lot of other things," he says. "If you mixed potassium nitrate with sulfur and charcoal, you got gunpowder. If you mixed it with sugar, you got a lot of smoke and a nice pink fire." He tested his explosive concoctions on a Fort Worth golf course: "I screwed the jar down tight and ran like hell." "kaboomWoosley", now an astronomer at the University of California at Santa Cruz, has graduated to bigger explosions--much bigger. Woosley studies some of the most powerful explosions since the birth of the universe: supernovae, the violent deaths of stars. The universe twi...
