From the Chattanooga Times Free Press:
The Tennessee Valley Authority will spend up to $160 million here over the next three years, trying to stay out of hot water at its biggest nuclear power plant.
TVA Chief Operating Officer Bill McCollum Jr. said the federal utility will add another cooling tower and expand four of the six existing towers to better cool water from the Tennessee River that's used for power generation at the Browns Ferry Nuclear Power Plant.
The work should be done by 2013, TVA officials said.
TVA rejected a similar proposal in 2005 when officials projected that the extra cooling capacity was not needed to keep the river within thermal limits set by state regulators. But hot weather forced TVA to limit Browns Ferry generation during two of the past four summers when river water temperatures approached allowable limits.
