Progress Energy, Progress Energy Crystal River Nuclear Power Plant could be back online by March 31, although the exact date has not been decided. A spokesman for Progress Energy said the utility expects to complete repairs and bring the plant back online in the first quarter. In September 2009, the plant had closed its doors for a scheduled shutdown for refueling and replacement of steam generators inside the containment. To move the two steam generators of 550 tons in the containment building, workers began removing concrete to create the 25-27-foot by opening the hatch because of the equipment of the reactor building was too small for generators.
In this work, a crack in the concrete was found in this area. Containment Crystal River is about 42 inches thick, contains both horizontal and vertical steel tendons strained, and is lined with steel sheets. The crack was found about nine inches from the outer surface of the concrete.
Progress Energy has spent about $ 250 million to repair the concrete containment.
