TVA Votes to Start Up Alabama Nuke

LCG, May 20, 2002-A Browns Ferry nuclear generator will receive $1.7 billion in an attempt to restart operation after being dormant since 1985.

The Tennessee Valley Authority voted late last week to bring the Alabama reactor back into service as one of the first significant additions to nuclear generation in decades.

In 1985 engineers found that the reactor's actual design did not parallel their blueprints perfectly and closed the plant. Before this discovery, the plant had had operating problems after a 1975 fire. While two generators were restarted in 1991 and 1996, the third was left off-line because it was not deemed necessary.

Now, despite protest from some residents fearing terrorist attack, TVA voted unanimously to rebuild the third reactor at the Browns Ferry plant, which is near Athens.

Others, such as members of Southern Alliance for Clean Energy and the Union of Concerned Scientist, opposed the renewal of the third unit because they felt that resurrecting such an old plant could result in serious problems and that the same money could be used to build a new, safer generator.

Environmentalists asserted that the $1.7 billion should have been spent cleaning up TVA's already operating fossil-fuel plants.

TVA serves 8.3 million people in seven states and owns 11 fossil-fuel, 3 nuclear, and 29 hydroelectric plants.
