Sites for Radioactive Waste
The withdrawal of Nevada’s Yucca Mountain as a potential nuclear waste repository has reopened the debate over how and where to dispose of spent nuclear fuel and high-level nuclear waste. In an article in the July 10 issue of Science, University of Michigan geologist RodneyEwing and Princeton University nuclear physicist Frank yon Hippel argue that, although federal agencies should set standards and issue licenses for the approval of nuclear facilities, local communities and states should have the final approval on the siting of these facilities. The authors propose the development of multiple sites that would service the regions where nuclear reactors are locateD、
"The main goal..., should be to provide the Unied States with multiple alternatives and substantial public involvement in an open siting and design process that requires acceptance by host communities and states," the authors write.
Ewing and yon Hippel also analyze the reasons why Yucca Mountain, selected byCongress in 1987 as the only site to be investigated for long-term nuclear waste disposal, finally was shelved after more than three decades of often controversial debate. The reasons include the site’s geological problems, management problems, important changes in theEnvironmental ProtectionAgency’s standard, unreliable funding and the failure to involve local communities in the decision-making process.
Going forward, efforts should be directed at locating storage facilities in the nation’s northeastern, southeastern, mid-western and western regions, and states within a given region should be responsible for developing solutions that suit their particular circumstances. Transportation of nuclear waste over long distances, which was a concern with the Yucca Mountain site, would be less of a problem because temporary storage or geological disposal sites could be located closer to reactors.
"This regional approach would be similar to the current approach inEurope, where spent nuclear fuel and high-level nuclear waste from about 150 reactors and reprocessing plants is to be moved to a number of geological repositories in a variety of rock types," said RodneyEwing, who has written extensively about the impact of nuclear waste management on the environment and who has analyzed safety assessment criteria for the controversial Yucca Mountain nuclear waste repository.
What does the author of the essay in the fourth paragraph want to sayA．Efforts should be made to solve the problems of transportation of nuclear waste over long distance.
B．Efforts should be made to develop as many nuclear disposal sites in the US as possible.
C．Efforts should be made to develop nuclear disposal sites to suit the circumstances of the region.
D．Efforts should be made to build up temporary nuclear disposal sites as possibl
网考网参考答案：C
网考网解析：
尽管第四段提到了尤卡山的确存在长距离运送核废料的问题，但不是这段的主要内容，所以A不是正确选项。作者说要在全国东西南北各地区建造核废料处置库，但没有说要尽量多的建造，所以B也不是正确选项。作者想表达的意思是：要在全国各地区建造核废料处置库，州政府必须根据地方特殊情况制定方案。所以，C是正确选项。D项因不符合文章内容故为错误选项。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
