The Advantages and Disadvantages of the Nuclear power
Nuclear power plants provide about 17 percent of the worlds electricity. Some countries depend more on nuclear power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power. There are more than 400 nuclear power plants around the world.
To build a nuclear reactor,what you need is some mildly2 enriched uranium. Uranium is a fairly common element on Earth,incorporated3 into the planet during the planets formation. U-235 is one of the few materials that can undergo4 induced fission. Raising and lowering the control rodsallow operators to control the rate of the nuclear reaction. When an operator wants the uranium core to produce more heat, the rods are raised out of the uranium bundle. To create less heat, the rods are lowered into the uranium bundle. The rods can also be lowered completely into the uranium bundle to shut the reactor down in the case of an accident or to change the fuel. The uranium bundle acts as an extremely high-energy source of heat. It heats the water and turns it to steam. The steam drives a steam turbine, which spins5 a generator to produce power.
Well-constructed nuclear power plants have an important advantage when it comes to electrical power generationthey are extremely clean. Compared with a coal fired power plant, nuclear power plants are a dream come true from an environmental standpoint. Unfortunately, there are significant problems with nuclear power plants. Mining and purifying uranium has not, historically, been a very clean process. Improperly functioning nuclear power plants can create big problems. The Chernobyl6 disaster is a good example. Spent fuel from nuclear power plants is toxic for centuries, and, as yet, there is no safe, permanent storage facility for it.
The nuclear crisis in Japan has developed rapidly, which makes us to think over about exploration of nuclear power. Fears about nuclear safety which took a generation to overcome have appeared again.
Supporters of nuclear power say nuclear power produces nearly no conventional air pollution, which is called as "clean energy몸. Besides, our technology develops quickly. Therefore, risks such as natural disaster can be avoided. we can benefit from the exploration of nuclear power.
However, opponents worry that the complexity of design and engineering of nuclear plants. Any failure or operation error could lead to serious result. It will pollute soil and plants and do harm to humans and animals.
In my eyes, we should continue the exploration of nuclear power. Not only does it bring lots of profits but also it is the best choice we have. Compared with other energies like sunshine, wind, and garbage, it is best to solve the shortage of coal and natural gas. As you know, it is the most efficient and realistic means of meeting the rapidly-growing demand for power.
