| Title | Power Reduced to Comply with River Water Quality Standards |
| Event Description | On August 7, 2008 Browns Ferry Nuclear Plant Units 1, 2, & 3 reduced reactor power to 50 percent to ensure continued thermal compliance with water quality standards as regulated by the Alabama Department of Environmental Management. This was caused by an unexpected failure of cooling tower components, rendering the cooling towers unavailable. Plant Operations continues to monitor river conditions and may take further actions as required to maintain compliance.
There were no safety systems challenged during the power reductions. This is an informational report based on media interest. TVA does not expect to make an official news release. The NRC Resident Inspector was notified. |
