Final answer:
Replacing a coal-burning power plant with a nuclear power plant results in a reduction in greenhouse gas emissions and improved energy efficiency, among other benefits. The correct answer is options A and D.
Step-by-step explanation:
Replacing a coal-burning power plant with a nuclear power plant has several benefits. One of the benefits is a reduction in greenhouse gas emissions. Coal-burning power plants release a significant amount of carbon dioxide, which contributes to global warming. In contrast, nuclear power plants do not produce carbon dioxide directly. Another benefit is improved energy efficiency.
Nuclear power plants operate at a higher efficiency compared to coal-burning power plants, meaning they can generate more electricity using the same amount of fuel. Additionally, nuclear power plants produce less waste compared to coal-burning power plants. Therefore, the correct choices are a) Reduction in greenhouse gas emissions and d) Improved energy efficiency.
