| Title | Press Release Concerning Additional Containment Delamination |
| Event Description | Progress Energy Florida, Inc. has notified the Florida Public Service Commission (FPSC) that the Crystal River Unit 3 (CR-3) Nuclear Plant will remain out of service while the company conducts a thorough engineering analysis and review of a new delamination. Options to return the plant to service will be analyzed after the report is complete. The company cannot estimate a return to service date for CR-3 at this time.
In mid-March, final retensioning of tendons within the CR-3 containment building was suspended while engineers investigated evidence of an additional delamination (or separation) resulting from the tendon retensioning work. The initial damage occurred in late 2009 in the concrete at the periphery of the containment building while creating an opening in the structure to facilitate the replacement of the steam generators inside. The unit was already shut down for refueling and maintenance at the time the damage was found. The plant has been shut down since September 2009 and there continues to be no threat to public health and safety. Progress Energy continues to coordinate repair and restart plans with Nuclear Regulatory Commission officials. The licensee notified the NRC Resident Inspector. |
