To meet growing international demand for energy,scientists and politicians are looking beyond the traditional energy sources of oil and coal to other less developed technologies.One such technology is nuclear power,which uses radioactive fuels such as uranium to generate energy.Although some people believe that nuclear power plants should be built on a large scale to supply some of the world's energy needs,critics argue that nuclear power is unsafe and too costly.In addition,there are better alterative technologies. First,nuclear power plants present safety concerns.Radioactive materials that are used to generate energy in nuclear reactors (where the energy-generating reactions take place)pose a potential threat to human health.The risk of radioactive material escaping from the reactor into the environment increases greatly if the core of a reactor overheats.The public is uneasy about the safeguards presently in place to prevent reactors from becoming too hot. Second,it is more expensive to build nuclear power plants than other types of plants.The construction of a typical nuclear power plant costs at least $2 billion and can be up to $5 billion.Nuclear plants are so much more expensive than conventional coal and oil plants because the specialized safety equipment they currently use to safeguard against accidents is expensive,and they may become still more expensive in the future if the public continues to demand even greater safety. Third. there are other technologies that are better and cheaper than nuclear power. Wind turbines. for instance, are completely safe and. according to recent analyses, cost less than nuclear power. Further, turbines run on a renewable source of energy (wind), so their energy source will never be depleted.

The reading passage presents three pieces of evidence about the disadvantages of nuclear power plants. The lecture contends that all the criticisms are unconvincing and respectively refutes each of the points made in the passage. Firstly, the reading passage makes clear that the nuclear power plants present safety concerns as radioactive materials used to generate energy pose a potential threat to human health. And the overheating of the core of a reactor can be risky and unable to predict. The lecturer, however, opines that people needn't worry about the safety of overheating, because as the temperature becomes higher, the reactor will slow down. When building up the energy, the nuclear power plants will control the heating on a safe level. Secondly, according to the reading passage, it is more expensive to build nuclear power plants than other types of plants because of the specialized safety equipment and the public concern demands. Nonetheless, the lecturer rebuts this by arguing that people often assume the expense of such plants is high in the term of the equipment, but there is not only thing to consider. When it comes to the other factors, the expenses of nuclear power plants are comparatively cheap. Overtime, the nuclear power plants will save more than conventional plants in terms of financial sense. Thirdly, the reading passage maintains that there are other technologies that are better and cheaper than nuclear power, such as wind turbines. Casting doubt on the claim, the lecturer floats the idea that the wind energy is unpredictable. She suggests that the wind energy may be strong on one day, but weak the other day. As a result, it is reliable. Every country which chooses the wind turbines as energy sources will definitely have another way to generate energy as backup. So wind energy cannot be a comprehensive energy solution.

Section Title: 6.文章修订

The reading passage presents three arguments against the use of nuclear power plants, while the lecture counters each of these points, asserting that the criticisms are unconvincing.

Firstly, the reading passage highlights safety concerns surrounding nuclear power plants, specifically the potential threat to human health posed by radioactive materials and the risk of reactor core overheating. In contrast, the lecturer argues that overheating is not a significant concern due to new reactor designs called pebble bed reactors. These reactors self-regulate their temperature; as the core temperature rises above normal operating levels, nuclear reactions slow down, preventing excessive heat buildup and maintaining a safe temperature.

Secondly, the reading passage asserts that constructing nuclear power plants is more expensive than other types of plants due to specialized safety equipment and public demand for increased safety measures. The lecturer refutes this by emphasizing that while initial construction costs may be high, uranium—the radioactive fuel required for nuclear energy production—is comparatively cheap compared to traditional fuels like coal and oil. Over time, savings on nuclear fuel offset high construction costs, making nuclear power plants financially viable when considering long-term expenses.

Lastly, the reading passage suggests that alternative technologies such as wind turbines are better and cheaper than nuclear power. However, the lecturer disputes this claim by pointing out that wind energy is unpredictable and unreliable. Wind strength can vary greatly from day to day; consequently, countries relying on wind power typically require backup energy sources to ensure consistent power generation. In contrast, nuclear power provides a steady output without needing backup sources—making it a more comprehensive energy solution than wind energy alone. (271 words)
