Question

Which of the following would most likely result in an increase in the use of nuclear power? A. the invention of a safe radioactive-waste disposal method B. the discovery of a cleaner method of burning coal C. a decrease in taxes on fossil fuels D. increased oil exploration in Alaska

Short answer

The invention of a safe radioactive-waste disposal method (Option A) would most likely result in an increase in the use of nuclear power, as it directly addresses one of the main concerns associated with nuclear energy production.

Step-by-step solution

(Understanding the Options)

(Start by breaking down each of the options given and understanding how they might influence the use of nuclear power: Option A: the invention of a safe radioactive-waste disposal method This option could potentially make nuclear power more attractive, as one of the main concerns about nuclear power is the safe disposal of radioactive waste. Option B: the discovery of a cleaner method of burning coal This option would make the use of coal more environmentally friendly, which might make it a more attractive option as an energy source compared to nuclear power. Option C: a decrease in taxes on fossil fuels Lower taxes on fossil fuels could make them cheaper, which would potentially decrease the incentive to choose nuclear power over other energy sources. Option D: increased oil exploration in Alaska This option would lead to increased oil production, which might make oil an even more competitive energy source compared to nuclear power.)

(Evaluate and Choose the Best Option)

(Compare each option and determine which would most likely have the greatest positive impact on the use of nuclear power: Option A directly addresses one of the main concerns about nuclear power, and its safe disposal could make it more appealing and increase its usage. Option B makes coal, an alternative energy source, more environmentally friendly, which could potentially decrease the use of nuclear power. Option C makes fossil fuels, another alternative energy source, cheaper, which also could potentially decrease the use of nuclear power. Option D focuses on increasing oil production, another alternative to nuclear power, which could make it more competitive and less likely for nuclear power to be chosen. Based on these evaluations, Option A seems to address an issue with nuclear power directly and has the highest potential of increasing its use.) Therefore, the correct answer is: A. the invention of a safe radioactive-waste disposal method

Key concepts

Nuclear Energy Safety

When discussing nuclear power, safety is a prime concern. The Chernobyl and Fukushima disasters highlighted the potential risks associated with nuclear energy. However, advancements in technology and tighter regulations have significantly improved the safety measures of nuclear reactors. Modern reactors are designed with multiple safety systems that work independently to prevent accidents, including containment structures and emergency shutdown systems known as SCRAM.

Education on nuclear safety often emphasizes the importance of operator training, as human error can be a critical factor in nuclear accidents. Nuclear power plants employ rigorous safety protocols to prepare for various potential scenarios. Simulations and drills are routine, ensuring the staff can effectively mitigate risks and handle emergencies. The investment in safety education results in a well-informed workforce committed to maintaining robust safety standards in nuclear facilities.

Radioactive Waste Disposal

The disposal of radioactive waste is a significant concern in the debate around nuclear energy. It is essential to manage this waste carefully to protect people and the environment from radiation. Currently, high-level waste is stored at reactor sites in thick, steel-lined concrete containers with plans for eventual transfer to long-term geological repositories.

Researchers are exploring innovative methods such as vitrification, where waste is mixed with glass-forming materials and solidified into stable glass forms. On the education side, this complex process is broken down for students to understand the engineering and scientific principles behind waste processing and storage, emphasizing the importance of long-term monitoring and maintenance. The development and implementation of safe radioactive waste disposal methods, like those described in Option A of the exercise, could significantly increase the public's confidence in nuclear power and make it a more attractive energy source.

Alternative Energy Sources

In the context of global energy needs, alternatives to fossil fuels are increasingly important. These alternatives include solar, wind, hydro, and geothermal energy. Each of these sources has its advantages and limitations. For example, solar and wind power rely heavily on weather conditions and require efficient energy storage solutions to manage supply fluctuations.

Educational content on alternative energy sources often includes comparing their impact on the environment, scalability, and long-term sustainability. Lessons involve analyzing energy production data, the efficiency of different technologies, and their suitability for various geographic locations. By educating students about all available options, including improvements in coal-burning processes or the economics of fossil fuels as mentioned in Options B and C, they can better understand the diverse energy landscape and its implications for the future.
