{{B}}Text 1{{/B}}
A factory that makes uranium fuel for nuclear reactors had a spill so bad it kept the plant closed for seven months last year and became one of only three events in all of 2006 serious enough for the Nuclear Regulatory Commission to include in an annual report to Congress. After an investigation, the commission changed the terms of the factory's license and said the public had 20 days to request a hearing on the changes.
But no member of the public ever did. In fact, no member of the public could find out about the changes. The document describing them, including the notice of hearing rights for anyone who felt adversely affected, was stamped "official use only," meaning that it was not publicly accessible.
The agency would not even have told Congress which factory was involved were it not for the efforts of Gregory B. Jaczko, one of the five commissioners. Mr. Jaczko identified the company, Nuclear Fuel Services of Erwin, Tenn,, in a memorandum that became part of the public record. His memorandum said other public documents would allow an informed person to deduce that the factory belonged to Nuclear Fuel Services.
Such secrecy by the Nuclear Regulatory Commission is now coming under attack by influential members of Congress. These lawmakers argue that the agency is withholding numerous documents about nuclear facilities in the name of national security, but that many withheld documents are not sensitive. The lawmakers say the agency must rebalance its penchant for secrecy with the public's right to participate in the licensing process and its right to know about potential hazards. The agency, the congressmen said, "has removed hundreds of in nocuous documents relating to the N. F. S. plant from public view."
With a resurgence of nuclear plant construction expected after a 30-year hiatus, agency officials say frequently that they are trying to strike a balance between winning public confidence by regulating openly and protecting sensitive information. A commission spokesman, Scott Burnell, said the "official use only" designation was under review.
As laid out by the commission's report to Congress and other sources, the event at the Nuclear Fuel Service factory was discovered when a supervisor saw a yellow liquid dribbling under a door and into a hallway. Workers had previously described a yellow liquid in a "glove box," a sealed container with gloves built into the sides to allow a technician to manipulate objects inside, but managers had decided it was ordinary uranium. In fact, it was highly enriched uranium that had been declared surplus from the weapons inventory of the Energy Department and sent to the plant to be diluted to a strength appropriate for a civilian reactor. If the material had gone critical, "it is likely that at least one worker would have received an exposure high enough to cause acute health effects or death," the commission said.
Generally, the Nuclear Regulatory Commission does describe nuclear incidents and changes in licenses. But in 2004, according to the committee's letter, the Office of Naval Reactors, part of the Energy Department, reached an agreement with the commission that any correspondence with Nuclear Fuel Services would be marked "official use only."
单选题 Why did no member of the public request any hearing?
【正确答案】 D
【答案解析】[解题思路] 原因细节题。文章第二段第二句强调词in fact后面就说明了原因:公众没法了解这些变化。
单选题 It can be inferred from the first three paragraphs that
【正确答案】 A
【答案解析】[解题思路] 推理题。文章第三段第二句“Mr.Jaczko identified the company,Nuclear Fuel Services of Erwin,Tenn.,in a memorandum that became part of the public record.”说明 Mr.Jaczko的备忘录已经成为公共记录的一部分。B选项错误是由于原文第三段首句是个虚拟语气,真实的状况是“The agency have told the Congress”。
单选题 NRC is criticized by Congress members chiefly because
【正确答案】 B
【答案解析】[解题思路] 原因细节题。第四段第二句说:这些立法者认为该机构以国家安全为旗号隐藏了大量的关于核设施文件,但是其中很多都不是敏感性文件。换句话说,就是“他们认为NRC隐藏了不该隐藏的信息”,也就是[B]选项。
单选题 The word "innocuous"(last sentence, paragraph 4) is closest in meaning to
【正确答案】 A
【答案解析】[解题思路] 含义题。文章第四段已经说明NRC把不该隐藏的文件藏起来了。本句话说“公司不让公众看到……的信息”,足以证明这种信息是没有保密价值的。因此,只有[A]选项符合题意。
单选题 Which of the following is true according to the text?
【正确答案】 C
【答案解析】[解题思路] 判断题。依据点在原文第六段中间由in fact开头的句子,这句话说:实际上,这是高浓缩铀,据宣布是能源部武器库剩余的,要运到工厂里稀释到合适强度以用于民用反应堆。由此可见,高浓缩铀可以被稀释以用于民用。
