　　A <a href="http://www.lxw***/new.php?id=1915">Proposal</a> to Research the Storage Facilityfor Spent Nuclear Fuel at Yucca MountainRoger BloomOctober 1997Introduction Nuclear power plants produce more than 20 percent of the electricity used in the United States[Murray,1989].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.***mercial 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 N*** 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 fue*** 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 sit*** 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(...

　　剑桥商务英语proposal格式是什么?

　　你好，通过商务英语高级的来答一下。

　　商务英语中的Proposal一般分为四个部分。

　　***troduction：简要表明你写这篇文章的目的。

　　2.Background：直接说明存在的问题。

　　3.Recommendations：为了解决问题提出一个切实可行的方案并说明这个方案的能带来的好处。

　　***nclusions：可以选择再次从侧面论证这个方案所能带来的好处，将会对公司产生什么有利的影响。

　　商务英语proposal不会写怎么办?

　　我在meeloun教育网里面帮你找到了关于商务英语proposal写作的基本格式，或许可以帮到你。

　　望采纳~1、信头The heading信头就是指书信中发信人的地址和发信的日期等。

　　通常情况下，公司都会专门印制带有信头的信笺纸，包括发信人的姓名，地址，电话，传真等。

　　当我们撰写传统信件时，直接使用这种信笺纸就可以。

　　2、编号(写信人的名字缩写)和日期The sender name and the date这部分内容是为了方便今后查询信件用的。

　　3、封内地址The inside address这里就是指收信人的姓名和地址，一般写在信笺的左上方。

　　收信人名称地址的格式和信头的格式相同，但必须把收信人的姓名一并写出。

　　另外，如果不是完全公事化的书信往来，或者已经从公事的关系渐渐发展成为带有私人性质的友好信件往来，由于称呼这一栏的内容已经说明了收信人的身份，所以可以不必填写封内地址。

　　4、事由The subject heading事由也就是我们通常说的主题，可以直接写明信件的重点，让人不必读完全信才了解到信的内容。

　　所以事由要写得简明扼要。

　　5、称呼The salutation指对收信人的一种称呼。

　　较常使用的有Dear Sirs,DearMadam,Dear Mr.XX，。

　　称呼后面的标点，一般使用逗号。

　　称呼里的个字母要大6、开头语The open sentences开头语没有统一的格式，但习惯上先用客套的语句把收到对方来信的日期，主题及简单内容加以综合叙述，使对方一目了然这是答复哪一封去信的。

　　如果是次通信，也可以利用开头语作必要的自我介绍，并表明目的要求。

　　开头语一般与正文分开，自成一节，要求简单明了。

　　7、正文The body of the letter信的主体。

　　一封信件的优劣，完全要看正文写的好或坏。

　　我们会在后面继续讨论写作商务信函的一些技巧、规则。

　　8、结尾语The complimentary close结尾语一般用来总结文本所谈的事项，提示对收信人的要求，如“希望来信来函定货”，“答复询问”等，另外也附加一些略带客套的语气。

　　正文结束后，另起一段写结尾语。

　　9、结束语The complimentary close结束语是结束信函时的一种客套，应该与前面的称呼相呼应。

　　例如：“Sincerely,”“Best Regards,”or“Yours Truly，”.结束语写在结尾语下隔一行，只有个字母大写，后面加逗号。

　　10、签名The signatrue写在结束语的下面，签上写信人的名字。

　　如果是传统的信件，写信人亲笔签上您的名字，因为用印章的话，说明该信件并非本人亲自过目，只是通函而已，不为人重视。

　　签名的下面，写上发信人的职位。

　　11、附件Enclosure如果信中有附件，应在左下角注明Encl.或Enc.。
