Prudent to promote development and utilization of nuclear energy. Advantages of nuclear energy are recognized the world: nuclear energy is not like coal and oil and other fossil fuels that produce air pollution, not emissions of greenhouse gas carbon dioxide; nuclear stability, efficiency, nuclear fuel, fossil fuel energy density is hundreds of times; in the normal operation, the nuclear power plant on the surrounding radiation dose produced by the public is not a threat to people.In fact, every energy development and utilization are accompanied by risks and drawbacks. In the process of development and utilization of nuclear energy, the biggest worry is that the public, artificial or extreme environmental factors may lead to leakage of radioactive material, harmful to the environment and human health. Further improve the use of nuclear energy capacity of human security to prevent potential hazards.
