The Tennessee Valley Authority has spent $30 million since the September 11, 2001, terrorist attacks on new barriers, guard towers and other security enhancements for its three nuclear stations.
The heightened security is in response to upgrades ordered at the nation's 103 reactors by the U.S. Nuclear Regulatory Commission in April 2003. The agency set an October 29 deadline to complete the security improvements.
TVA operates one reactor at the Watts Bar station near Spring City, Tennessee, two reactors at the Sequoyah station near Chattanooga Tennessee, and two reactors with a third scheduled to go on line in 2007 at the Browns Ferry station near Athens, Alabama.
TVA also increased communication with local, state and federal law enforcement agencies and extended the perimeters around the plants.
In addition, physical barriers were installed at Browns Ferry and other barriers will be placed at plant buildings at the Watts Bar and Sequoyah plants.
