The advantages and disadvantages of nuclear energy
Advantages of nuclear energy: 1. Nuclear power does not cause air pollution and does not produce carbon dioxide which aggravates global warming. 2. Nuclear fuel has small size so it is easy for transportation and storage. 3. Fuel costs accounts for a lower proportion in the cost of nuclear power generation. 4. Rich in nuclear material. Disadvantages of nuclear energy: 1. Nuclear power plant will produce radioactive waste. 2. Nuclear power plant has lower thermal efficiency and bad heat pollution. 3. Nuclear power plant needs large investment cost, the power company has higher financial risk. 4. The site of nuclear power plant is largely determined by environment. 5. The release into the external environment because of the accident will damage the ecology and people.
