Unfortunately, nuclear fission, the process used to create this large amount energy, creates significant amounts of high level radioactive waste. More than 30,000 metric tons of nuclear waste have arisen from U.S. commercial reactors as well as high level nuclear weapons waste, such as uranium and plutonium [Roush, 1995]. Because of the build-up of this waste, some power plants will be forced to shut down. To avoid losing an important source of energy, a safe and economical place to keep this waste is necessary. This document proposes a literature review of whether Yucca Mountain is a suitable site for a nuclear waste repository. The proposed review will discuss the economical and environmental aspects of a national storage facility. This proposal includes my methods for gathering information, a schedule for completing the review, and my qualifications. Statement of Problem On January 1, 1998, the Department of Energy (DOE) must accept spent nuclear fuel from commercial plants for permanent storage [Clark, 1997]. However, the DOE is undecided on where to put this high level radioactive waste. Yucca Mountain, located in Nevada, is a proposed site. There are many questions regarding the safety of the Yucca Mountain waste repository. Researchers at Los Alamos National Laboratory disagree over the long-term safety of the proposed high level nuclear waste site located in Nevada. In 1994, Charles Bowman, a researcher at Los Alamos, developed a theory claiming that years of storing waste in the mountain may actually start a nuclear chain reaction and explode, similar to an atomic bomb [Taubes, 1995]. The stir caused by theory suggests that researchers have not explored all sides of the safety issue concerning potentially hazardous situations at Yucca Mountain. Bowman's theory that Yucca Mountain could explode is based upon the idea that enough waste will eventually disperse through the rock to create a critical mass. A critical mass is an amount of fissile material, such as plutonium, containing enough mass to start a neutron chain reaction [Murray, 1989]. Bowman argues that if this chain reaction were started underground, the rocks in the ground would help keep the system compressed and speed up the chain reaction [Taubes, 1995]. A chain reaction formed underground could then generate huge amounts of energy in a fraction of a second, resulting in a nuclear blast. A nuclear explosion of this magnitude would emit large amounts of radioactivity into the air and ground water. Another safety concern is the possibility of a volcanic eruption in Yucca Mountain. The long-term nuclear waste storage facility needs to remain stable for at least 10,000 years to allow the radioactive isotopes to decay to natural levels [Clark, 1997]. There are at least a dozen young volcanoes within 40 kilometers of the proposed Yucca Mountain waste site [Weiss, 1996]. The proximity of Yucca Mountain to these volcanoes makes it possible to have a volcanic eruption pass through the spent fuel waste repository. Such a volcanic eruption could release damaging amounts of radioactivity to the environment. Objectives I propose to review the available literature about using Yucca Mountain as a possible repository for spent nuclear fuel. In this review I will achieve the following two goals: (1) explain the criteria for a suitable repository of high-level radioactive waste; and (2) determine whether Yucca Mountain meets these criteria. According to the Department of Energy (DOE), a repository for high-level radioactive waste must meet several criteria including safety, location, and economics [Roush, 1995]. Safety includes not only the effect of the repository on people near the site, but also people along the transportation routes to the site. In my research I will consider both groups of people. As far as location, a waste site cannot be in an area with a large population or near a ground water supply. Also, because one of the most significant factors in determining the life span of a possible repository is how long the waste storage canisters will remain in tact, the waste site must be located in a dry climate to eliminate the moisture that can cause the waste canisters to corrode. The economics involved in selecting a site is another criterion. At present, the Department of Energy 。

英语倡议书格式

A Letter of Appeal 一封倡议书 June XX, 20XX 20XX年6月XX日Dear friends，亲爱的朋友们， I am writing this letter to call on everyone to pay attention to the present disasters caused by human activities. As some of you may know, over the past years, floods, droughts, landslides, and dust storms have frequented our planet. Not long ago, tsunami swept the Southeast Asia, which caused enormous damage. All these have sounded an alarm to human beings. So it is high time that we join efforts to save our planet. 我写这封信是想呼吁大家关注目前由人类活动造成的灾害。

你们有些人可能知道，在过去的几年中，洪水，干旱，滑坡，和沙尘暴时常发生在我们的星球。不久前，海啸横扫东南亚，造成了巨大的损失。

所有这些都给人类敲响了警钟。所以现在正是我们共同努力拯救我们的地球的时候。

Above all, a task of top priority for us is to plant trees as many as possible, especially in the arid areas. At the same time, we should stop deforesting in large amount. And we can save our planet through many other ways, such as saving water and using recycled paper. 首先，我们首要的任务就是尽可能多地植树造林，特别是在干旱地区。同时，我们应该停止大量砍伐森林。

我们还可以通过很多其他的方式来拯救我们的地球，如节约水和使用再生纸。 So don't hesitate to act out these measures. Even a small action is meaningful to our planet. Please join us in the action of protecting our planet. If you are willing to do something to save our planet, please start from the little thing right around you. Thank you！ 所以不要犹豫采取这些措施。

即使是很小的行动对我们的地球也是有意义的。请加入我们保护地球的行动。

如果你愿意做一些事来拯救我们的地球，请从你身边的小事做起。谢谢！ Sincerely yours, YJBJS 真诚的 XXX。

There are more and more endangered animals at present,so how to protect them has been our task of top priority .It's wrong for people to hunt animals for their meat and feather,for they are our good friends.We should protect them instead of killing them.Giant pandas,which are one of the endangered animals,live in the forests and live on bamboo lealves.They can just live safely in the natural protection zones.We should stop killing animal and protect them.。
