Questions 36 to 40 are based on the following. In the early days of nuclear power, the United States made money on it. But today opponents have so complicated its development that no nuclear plants have been ordered or built here in 12 years.
The greatest fear of nuclear power opponents has always been a reactor “meltdown” (堆内熔化). Today, the chances of a meltdown that would threaten U.S. public health are very little. But to even further reduce the possibility, engineers are testing new reactors that rely not on human judgement to shut them down but on the laws of nature. Now General Electric is already building two advanced reactors in Japan. But don’t expect them ever on U.S. shores unless things change in Washington.
The procedure for licensing nuclear power plants is a bad dream. Any time during, or even after, construction, an objection by any group or individual can bring everything to a halt while the matter is investigated or taken to court. Meanwhile, the builder must add nice-but-not-necessary improvements, some of which force him to knock down walls and start over. In every case where a plant has been opposed, the Nuclear Regulation Commission has ultimately granted a license to construct or operate. But the victory often costs so much that the utility ends up abandoning the plant anyway.
A case in point is the Shoreham plant on New York’s Long Island. Shoreham was a virtual twin to the Millstone plant in Connecticut, both ordered in the mid-’60s. Millstone, completed for $101 million, has been generating electricity for two decades. Shoreham, however, was singled out by anti-nuclear activists who, by sending in endless protests, drove the cost over $5 billion and delayed its use for many years.
Shoreham finally won its operation license. But the plant has never produced a watt of power. Governor Mario Cuomo, an opponent of a Shoreham start-up, used his power to force New York’s public-utilities commission to accept the following settlement; the power company could pass the cost of Shoreham along to its consumers only if it agreed not to operate the plant! Today, a perfectly good facility, capable of servicing hundreds of homes, sits rusting.
第36题:What has made the procedure for licensing nuclear power plants a bad dream?
A) The inefficiency of the Nuclear Regulation commission.
B) The enormous cost of construction and operation.
C) The length of time it takes to make investigations.
D) The objection of the opponents of nuclear power.

At the 1986 Chernobyl nuclear accident, there was a very large release of radioactivity in a few minutes, followed by a slowly declining release rate over several months. The total release is estimated to have been about 5×10<sup>7</sup>curies The winds carried the released materials all the way to Sweden, from which the first reports came that there had been a nuclear accident in the USSR.
For the purposes of this problem assume that there was an instantaneous release of 10<sup>7</sup>curies of radioactive gases (and fine particles, which are assumed to remain in the atmosphere and not settle out). Then estimate the maximum ground level concentration of radioactive gases (curies/m<sup>3</sup>) when the radioactive cloud from the accident got to Sweden. Make the following assumptions:
(1) Ignore decay of the radioactive gases (i.e., assume their half-lives were infinite).
(2) Assume the distance between Chernobyl and Sweden is 1000 km.
(3) Assume that the wind speed was 3 m/s and the stability class C.
(4) Assume that the mixing height was 2000 m.
(5) Assume that mlXmg in the x direction(up and down the direction of the wind) has the same intensity as miXing in the y(crosswind)direction.
