Browns Ferry Cooling Towers – Addition and Replacements
Limestone County, Alabama
UPDATE: On December 6, 2012, TVA issued a supplemental environmental assessment (EA) and finding of no significant impact for the replacement of existing Cooling Tower 3. This replacement is necessary following the collapse of the tower in July 2012. The 2012 EA supplements the EA issued in 2010 (described below) which did not address the replacement of Cooling Tower 3.
On October 28, 2010, TVA issued an environmental assessment (EA) and finding of no significant impact for the replacement of four original mechanical draft cooling towers (MDCTs) with larger units and construction of one additional MDCT at Browns Ferry Nuclear Plant (BFN). Additional and more efficient cooling capacity is needed for current operation and for future increases in power output (known as “uprates”). During the summer of 2010, BFN operated at below 50 percent of power capacity for several days in July and for about half of August to meet water quality permit requirements. The new towers will help reduce the duration and frequency of power generation reductions (known as “derates”) at BFN. Extensive summer derates would be costly to TVA ratepayers.
TVA completed a Final Supplemental Environmental Impact Statement for Operating License Renewal of the Browns Ferry Nuclear Plant in 2002. This EIS included consideration of up to eight cooling towers for the plant, including replacement and new towers. Because the proposed new Tower 7 is in a different location from those considered in 2002, TVA has completed an EA of the proposed action.
