Nuclear Energy

Electric Generation

Dominion's nuclear stations provide about a third of the power generated in Virginia. In Connecticut, the Millstone Power Station provides about 50 percent of the electricity used in the state. In Wisconsin, the Kewaunee Power Station provides nine percent of the electricity in the state.

Annually, the Millstone, Kewaunee, North Anna and Surry Power Stations combined provide enough electricity to supply more than 2 million homes, while displacing about 45 million tons of carbon dioxide, 200,000 tons of sulfur dioxide and 75,000 tons of nitrogen oxides that would have been emitted to the air if that electricity had been generated by a fossil fuel station.

A byproduct of nuclear generation is used fuel. The used fuel is removed from the reactor and stored in thick concrete reinforced, stainless steel lined pools of water that are specially built, in accordance with Nuclear Regulatory Commission rules, to withstand earthquakes and other disastrous phenomena.

Another alternative, dry cask storage, was first licensed in the United States at the Surry Power Station (in 1986). Dry storage is another safe, secure alternative for interim storage. As of June 2009, 33 states have at least one independent spent fuel storage installation.

Other types of materials referred to as low-level wastes, such as clothing and filters, can also be byproducts of these operations.

Through our efforts at Dominion, the volumes of these wastes generated have been substantially reduced. The nuclear business unit has set pollution prevention goals over the next four years to further reduce a variety of types of wastes at Dominion stations.
