Three mile island nuclear power plant

America’s worst accident at a civilian nuclear power plant occurred on March 28, 1979, at Three Mile Island. Operators were trying to repair a problem with piping in the water circulation system, and they accidentally blocked the flow of water. This stopped the removal of heat from the reactor, and began a series of events that would change the way America thought about nuclear power.

Within ten seconds after the flow of water was blocked, the reactor vessel became hotter and the pressure rose. Safety control rods were automatically thrust down into the reactor, causing the chain reaction to stop completely. Pressure, however, continued to build. A relief valve opened but failed to close. As a result, too much water escaped, and the reactor began to melt down.

[1] Large quantities of radioactivity began to leak from the reactor. [2] Most of the radioactivity was contained, and it is likely that no one received a harmful amount of radiation. [3] “Three Mile Island” became the reason that many Americans are afraid of nuclear power to this day. [4]

which word refers to the part of a nuclear reactor in which the nuclear reaction takes place?

A. Vessel


 

B. Core


 

C. Circulation system


 

D. Control rods

Read the following passage and mark the letter A, B, C, D on your answer sheet to indicate the correct answer to each of the questions

Because geologists have long indicated that fossil fuels will not last indefinitely, the U.S government finally acknowledged that sooner or later other energy sources would be needed and, as a result, turned its attention to nuclear power. It was anticipated that nuclear power plants could supply electricity in such large amounts and so inexpensively that they would be integrated into an economy in which electricity would take over virtually all fuel-generating functions at nominal cost. Thus, the government subsidized the promotion of commercial nuclear power plants and authorized their construction by utility companies. In the 1960s and early 1970s, the public accepted the notion of electricity being generated by nuclear power plants in or near residential areas. By 1975, 54 plants were fully operational, supplying 11 percent of the nation’s electricity, and another 167 plants were at various stages of planning and construction. Officials estimated that by 1990 hundreds of plants would be on line, and by the turn of the century as many as 1000 plants would be in working order.

Since 1975, this outlook and this estimation have changed drastically, and many utilizes have cancelled existing orders. In some cases, construction was terminated even after billions of dollars had already been invested. After being completed and licensed at a cost of almost $6 billion, the Shoreham Power Plant on Long Island was turned over to the state of New York to be dismantled without ever having generated electric power. The reason was that residents and state authorities deemed that there was no possibility of evacuating residents from the area should an accident occur.

Just 68 of those plants under way in 1975 have been completed, and another 3 are still under construction. Therefore, it appears that in the mid1990s 124 nuclear power plants in the nation will be in operation, generating about 18 percent of the nation’s electricity, a figure that will undoubtedly decline as relatively outdated plants are shut down

How does the author describe the attitude of the population in regard to nuclear power as fuel in the early to the mid 1970s?

A. Apprehensive

B. Ambivalent

C. Receptive

D. Resentful
