Nuclear power is also very environmentally friendly. It produces hardly any air pollution, and it releases less radiation into the atmosphere than coal-burning power plants. What is nuclear Power?

Nuclear energy was first used in It is the result of nuclear fission. Nuclear fission is the process in which atoms are split and energy is released. When they split, and the atoms are unstable, they become radioactive. The fission occurs when a radioactive particle hits the nucleus of another atom. When the nucleus of the second atom splits, it gives off heat. This nuclear energy can be used to boil water, and give off steam.
This steam can be used to power turbines and electric generators. Although a lot of people think nuclear waste is a problem, there are ways that this waste can be safely disposed of. The nuclear power plants have a lot less waste than coal-burning plants and most of it is classed as a low-level of radioactivity. Transportation of waste is also not a problem, because there are only small amounts of waste that need to be transported.
They usually transport them in indestructible containers. The production of electricity by nuclear plants is very reliable. It is not affected by oil embargoes or industrial action. Some advantages of nuclear energy are; that it provides adequate heat, it efficiently produces large amounts of electricity about MW of electricity per day. Also nuclear plants dont pollute the atmosphere. Since nothing is burned, the air is free of soot, carbon dioxide and other by-products of conventional fuel burning.
Also, nuclear power uses a very small amount of the Earths resources. Nuclear fuel is also very inexpensive, the energy that is generated is the most concentrated source and the waste is more compact than any other source.

There is also extensive scientific basis for the cycle, and the fuel is easy to transport as new fuel. With nuclear fuel there is no greenhouse or acid rain effects.
However, there are also disadvantages to Nuclear Power Plants. Nuclear Power Plants use uranium, one of the rarest elements in nature. Uranium is a NON-renewable source. Nuclear power plants are also very expensive to build. There is also danger if steam explosions from the failures in the cooling systems, this is a potential hazard. Also, too much exposure to the radiation can be fatal or cause cancer. Some countries use nuclear power as a primary source of energy, and almost all countries use nuclear power on some level.
Where there is nuclear power there is radiation. There has been a misunderstanding on how dangerous radiation is. What people dont realize is that they are exposed to radiation on a daily basis, but the radiation is so minimal that there is no medical proof that radiation is responsible for health problems. Nuclear reactors are the same way. No one has been able to prove that people become ill because they live near a nuclear facility. Other controversies are over the extensive nuclear waste that comes from power plants. Scientists have long known how to deal with radioactive waste, but so far, the U.
S government hasnt implemented these recommendations. Nuclear power is not destructive to the environment as some people say, but has beneficial qualities for Americas power supply needs.
Nuclear power is the most scrutinized power supply in the world. Environmentalists feel the use of nuclear power is too costly to the environment for humans to use. One allegation is that radiation leaks out of the reactor and into the air and water, causing thyroid disease. Researchers found that conclusions of 3, people who apparently had thyroid disease because of the release of radioactive iodine from Hanford were false Sternberg.

All of these people were born between and when Hanford was built. Researchers showed that Hanford was not the result of the thyroid disease Sternberg.
Since nuclear reactors need lots of water, they are always located on major rivers. This is another suspected problem with nuclear power. Environ-mentalists think nuclear power plants heat river waters and damage the aquatic life. They conclude that this isnt only from nuclear power, but it is true from all sources of power manufacturing. The cooling water from these power plants heat rivers to temperatures where cold-water fish cant survive.
The fish that are affected are Walleye, Yellow perch, white sucker, and fathead minnow. The temperature range is 84 - 88 F, which the Columbia is said to be just a few degrees off those temperatures Forman 52 - 3. The water temperature also affects spawning as well. When the fry hatch, they need aquatic organisms to eat.
When the water temperatures rise, these organisms do not flourish, causing food shortages for the fish. Environmentalists conclude that the rise in water temperatures also creates an environment for algae, which could cause the water to be unsuitable for humans. However, if these allegations were true, we would see several changes in the rivers where these power plants are located. If this were true, then why do we still have fishermen on the rivers?
Wouldnt that eventually cause a complete loss in life in these rivers?
eryjimyjox.tk Also, the algae would be so bad that the whole river would be affected. According to the environmentalists, trout and salmon would not be able to survive in rivers with power plants on them, and of course we know thats not true. They also mention that heated water makes fish weak and gives fish more of a chance to acquire diseases. However, the environmentalists dont seem to convinced because they say, together, these may result in a significant loss of fish from disease, but in effect, the mortality is caused by a temperature that permits a normally low incidence of disease to become an epidemic Forman This gives the reader the understanding that they really dont know how heat effects fish, but they are willing to try to explain it.
Another concern people have, is the amount of radiation that is released by nuclear power plants. The Bureau of Radiological Health is responsible to keep reports on the amount of radiation released in the area of these power plants Foreman A study done by the Bureau of Radiological Engineering Laboratory on a nuclear power plant in Illinois concluded that there was no external radiation exposure to the surrounding areas.
They tested several different sources such as water, earth, cattle, and vegetation around the nuclear site Foreman In the areas tested, only 5 millie a year of radiation could be calculated. To put this in context, each human receives 85 millie of radiation a year through natural sources. These natural sources consist of; sun, walls in houses, bricks or concrete, and even the TV. When someone goes in for an X-ray, they receive anywhere from 90 to millie per year.
So that 5 millie could be simply from the natural ground Cohen Everyone has heard of Three Mile Island in March It was plastered all over the news that radiation was leaking and we were going to see another Hiroshima.
