Nuclear Energy

Nuclear energy has long posed a dilemma for environmentalists. As a cheap, clean source of power that does not use fossil fuels or add greenhouse gases to the atmosphere, it offers an appealing alternative to power from traditional coal-fired plants. Yet nuclear energy is associated with troubling environmental issues, including the problem of radioactive waste disposal.

Background

The U.S. nuclear power industry is composed of 103 reactors in 31 states that together generate about 20% of the nation's power. Electricity production from nuclear power plants exceeds that from oil, natural gas, and hydropower sources, and is second only to coal.¹ While construction costs for nuclear plants are high, the cost of nuclear power per kilowatt-hour (kwh) to consumers is comparable to that of coal.²

Nuclear energy production involves the fission, or splitting, of uranium atoms. When an atom splits, a small portion of its mass is converted to energy, and the remainder is converted to heat. Under the right conditions, it can set off a chain reaction that splits other atoms. Commercial production of nuclear energy maintains a controlled chain reaction within the reactor of a power plant, converts the heat released by the atoms to steam, and uses the steam to generate electricity.³ The energy produced from splitting atoms is far greater than the energy produced from combustion of the same amount of matter, so production of nuclear energy requires less land and fewer materials, and generates less waste, than production of energy from burning fossil fuels
