Nuclear power plants provide about 17 percent of the world's 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 (核反应堆),what you need is some mildly2 enriched uranium(铀). Uranium is a fairly common element on Earth,incorporated3 into the planet during the planet's formation(形成). U-235 is one of the few materials that can undergo4 induced fission(诱发性核裂变). Raising and lowering the control rods(杆,棒条) allow operators to control the rate of the nuclear reaction.When an operator (操作员) wants the uranium core to produce more heat,the rods are raised out of the uranium bundle(捆,束). 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 bundleactsasanextremely high-energy source of heat. It heats the water and turns it to steam. The steam drives a steam turbine(汽轮机), which spins5 a generator(发电机) to produce power.
Well-constructed nuclear power plants have an important advantage when it comes to electrical power generation——they are extremely clean. Compared with a coalfired power plant, nuclear power plants are a dream come true from an environmental standpoint (立场,观点). Unfortunately, there are significant problems with nuclear power plants. Mining and purifying(提纯) uranium has not, historically, been a very clean process. Improperly func- tioning nuclear power plants can create big problems. The Chernobyl6 disaster is a good example.Spent fuel from nuclear power plants is toxic (有毒的) for centuries, and, as yet, there is no safe, permanent(永久的) storage facility for it.

Last week,we had a debate about whether we should develop nuclear power stations.Opinions are divided.
During the debate,Some students said we should develop nuclear power stations,since it would bring much electricity to people,and reduce the pressure of using electricity in the world.Meanwhile,it can create more jobs.
Hoever,the others thought the government should limit the number of nuclear power stations,since they will cause all kinds of pollution,air pollution included.They thought solar energy power stations,which are environmentally friendly ,should be developed.

核能(Nuclear Energy)
Nowadays,energy can be obtained through various sources such as oil,coal,natural gas,solar heat,wind,etc.But the conventional energy like oil,coals are being used up rapidly,and solar heat can't become widely used immediately for technological reason.In my opinion,unclear energy will take the place of conventional energy,because people now can control this energy freely,and unclear energy is non-polluting,inexhaustible,and it's much safer than coal and oil.Coal and oil are burned,they also produce many harmful gases,and the air has been seriously polluted by such gases,which will threaten people's living environment.And many accident happened because of the wrong use of such energies.
However,such things can't happen when we use nuclear energy,Though when the nuclear leaks out,it will do great harm to people' s health and the environment.We can do enough work to avoid such things,and limited such things at a low percentage.
