    Nuclear Power: Benefits and Risks

    Fangchao Group 4

     A huge earthquake has destroyed a large part of northeastern Japan. The earthquake has caused people’s death and missing. It also made sorrow and grief. However, the crisis at the Fukushima Daichi nuclear power center is the worst Japan has ever faced. Firefighters and military are risking their lives to control situation. People are full of fears about the effect of radiation. At the present ,the debeat about nuclear power plant is becoming much heated.I have made some researches about this topic .And both its advantages and disadvantages should be taken into consideration.

    The benefits of nuclear power plant

     Since its discovery in the fifties, nuclear power has accounted for 17 percent of the world’s electricity supply in the second half of the

    century. With the rapid development of the world, many countries have to face the shortage of energy. To solve this problem, most of them have been focusing on researching new energies. Then nuclear power stations have come out in succession.

     Nuclear power had been considered to be a kind of safe and efficient energy until the accident of Chernobyl happened.The power has been a great addition in many areas around the world. But some may argue that it might also do some harm to our environment, but it should

    be noted that it is not the only source of energy that is damaging to the environment, and even is not the most serious one. What’s more, it has an abundant way of using and electricity is definitely not the only one.

     Besides, nuclear energy is clean and not expensive. Nuclear power plants do not produce carbon dioxide or toxic gases. Over the world, the majority of electricity is produced by burning coals which can enhance global warming and air pollution. Therefore, China should use more alternative energy and one of the best choices is

     With the global warming issues that are surrounding us and the desire to find a solution to the energy crisis, the use of nuclear has an ability to solve many problems than it will cause.

The risks of nuclear power plant

     Opponents of nuclear power usually talk about the risk of accidents. Namely: the first major nuclear power plant accident in Pennsylvania in 1979; the Chernobyl Nuclear Power Plant disaster in 1986; and recently the Fukushima nuclear leak in Japan.And this time, the earthquake in Japan, once again sounded the alarm to us. Some so-called “experts” were very quick to claim that we should abandon nuclear power for its great threat. But I just can’t go along with the idea.

    Many people still argue that any nuclear incident is hard to estimate and predict. Once it happened, it was a worldwide disaster. The damage of

    Fukushima incident has already exceeded what the experts estimated.

     The greatest fear about nuclear power plants is a severe accident in the nuclear reactor. When the whole system or an individual component of a nuclear power plant causes the reactor core to malfunction, it is known as a nuclear meltdown. This occurs most commonly when the sealed nuclear fuel assemblies that house the radioactive materials begin to overheat and melt. If the meltdown becomes too severe, the radioactive elements within the core can be released into the atmosphere and around the area of the power plant. These radioactive materials are highly toxic to all organic life.Because of the geometric design of the reactor cores, a nuclear explosion is impossible; however, smaller explosions such as the release of steam are possible.

     They are no wrong, because the risk of catastrophe can never be brought to be zero. However, statistics demonstrate that the safety record of nuclear power compares very favorably with the record of other means of energy generation in terms of death or injury caused to persons. And in addition to that, I really doubt that is nuclear power the only factor that should be responsible to all these accidents? If so, what about the inability of plant operators to recognize and respond to the reactor’s condition? What about the unqualified buildings of nuclear power plant? Well, another worry about nuclear power is the connection with military

    uses, for me, I believe that nuclear weapon can be controlled well due to all the efforts we make.

     Some people hold their thoughts that we should give up nuclear power. It lied in many aspects.For example, the production of nuclear power is based on the destruction of environment which has been paid attention to bypeople all over the world.The heat that nuclear power produces will result in temporature going up and eventhreaten to our security if war happens.

     The long-term danger of nuclear power plants is the disposal of waste products. This waste includes materials that were used in the nuclear fission process. Spent uranium rods contain the highest level of toxins and radiation. They need to be stored in facilities that provide secure and protective barriers to prevent theft or exposure to the soil or water. Most of these facilities are located deep underground. Countries that use nuclear power need to manufacture ways to store these wastes for thousands of years.

     “Although the process of nuclear power from an idea to a commercial reality has witnessed many successes, it has also had its share of failures. Unfortunately, the failures make more news and therefore catch the attention of the public. The successful stories are seldom publicized.”

     Every coin has two sides, so does nuclear power. It is undeniable that technology makes our life more convenient and efficient, but is there some kind of hidden crisis behind the convenient and efficient life? Pesticides being prevalent; fertilizers undermining our health; melamine running a tragedy. Hence I believe the future of nuclear power depends entirely on the direction we choose, effort we make and concept we agree on. Rationally and wholeheartedly, I contend that the nuclear power can be miraculous power. Like the bulb on lightening, it should be shinning as a beacon at the cross in this nuclear age and we are the finest possible guardians of that, setting a sustainable key to open the tough energy door. As the forerunner of the bright future, the bulb is not for the mouth after all. And the nuclear power also needs further efforts to establish sound rules and find right place.
