The company is now making preparation for pre-start testing and is targeting return to service in the first quarter of 2011.
The company completed the concrete replacement last month. Once the interior tendons are re-tightened, a series of structural tests will be completed and following those tests, the unit will return to normal operation.
The company said that a portion of the building was damaged late last year during the process of creating an opening in the structure to remove and replace the steam generators inside.
The unit was already shut down for refueling and maintenance at the time the damage was found.
