Experts Call for Local and Regional Control of 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 Rodney Ewing and Princeton University nuclear physicist Frank von 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 sitting 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 United States with multiple process that requires acceptance by host communities and states," the authors write.
Ewing and yon Hippel also yze the reasons why Yucca Mountain, selected by Congress 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 the Environmental Protection Agency’s standard, unreliable funding and the failure to involve local communities in the decision- 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 in Europe, 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 Rodney Ewing, who has written extensively about the impact of nuclear waste management on the environment and who has yzed safety assessment criteria for the controversial Yucca Mountain nuclear waste repository.

E.
It is (52) over two million years that human beings used chips, but human (53) changed so little at that time. Now we have made use of silicon chips for merely (54) years, but our life is changing faster with each passing day.

B.
In 1874 it was a country village, but it was the home of the All England Croquet Club. The Club had been there since 1864. A lot of people played croquet in England at that time and enjoyed it, but the national championships did not attract many people. So the Club had very little money.

D.

There was some surprise and doubt, of course, when the Club allowed women to play in the first women’s singles championship in 1884. But the ladies played well -- even in long skirts that hid their legs and feet. Until 1907 the winners, both men and women, were always British, but since 1936 the victory has usually gone to an American or an Australian. British people were very happy when an English girl, Ann Jones, won the championship in 1969.
