Browns Ferry Unit 1 Operating Issues Since the Restart in May 2007

We reviewed certain Browns Ferry Unit 1 (BFN U1) operating issues that have occurred since the restart in May 2007. We found the operating issues were primarily caused by improper installation of a fitting during the restart project and another fitting during initial construction, original plant design errors, failure to identify the correct root cause of a previous issue in a timely manner, and failure to identify a missing wood support during walkdowns. The root causes for the SCRAMs (safety control rod axe man) appear to not be the result of work performed under project milestones tied to the Unit One Executive Compensation plan. In addition, we found the total cost of the BFN U1 project to be approximately $1.8 billion through fiscal year 2007.
