NRC TO BEGIN SPECIAL INSPECTION AT CRYSTAL RIVER NUCLEAR PLANT 

The Nuclear Regulatory Commission is sending a special inspection to the Crystal River 

nuclear power plant, operated by Progress Energy on the west coast of Florida about 80 miles 

north of Tampa. The inspection team will inspect and assess circumstances associated with a 

crack discovered in the concrete of the containment building. 

The plant had shut down for a planned refueling outage and to replace the steam 

generators inside containment. To move the large steam generators into the containment 

building, workers began removing concrete to create the necessary opening. During that work, a 

crack in the concrete was found in that area. The Crystal River containment is about 42 inches 

thick, contains both horizontal and vertical tensioned steel tendons, and is lined with steel plate. 

The crack was found about nine inches from the outer surface of the concrete. 

After being notified, the NRC resident inspectors began to review the situation and 

several other specialized NRC inspectors who were at Crystal River to evaluate the outage 

activities also provided expertise. Plans for the agency’s Special Inspection Team are still being 

made, but its members will be comprised of inspectors and experts from the Region II office in 

Atlanta and NRC headquarters in Rockville, Md. It is also likely the NRC will contract one or 

more independent experts to assist in the inspection. 

“The discovery of this crack in the concrete does not appear to represent a major 

reduction in safety, and there are no immediate concerns because the plant is shut down,” said 

NRC Region II Administrator Luis Reyes. “However, we want to make sure we have the right 

inspection resources to fully understand any safety implications before the plant restarts.” 

NRC Chairman Gregory Jaczko and Regional Administrator Reyes will make a 

previously planned trip to the Crystal River site for Friday, Oct. 9, and both the agency’s 

Chairman and top official in the southeast will get a firsthand look at the containment. 

The special inspection will review all the circumstances surrounding the crack in the 

containment building, determine potential generic issues for other nuclear plants with similar 

designs (although no similar separations in concrete have been discovered at those plants), and 

assess any effects on the plant’s inspection program.

Progress Energy is performing an analysis of the concrete and overall containment to 

determine if there are safety implications and what may need to be done prior to the plant 

restarting. The NRC will review any analyses completed by the company as well as perform its 

own independent evaluations. 

The NRC special inspection will continue for several weeks during the plant’s outage and 

the plant will not restart until the agency is satisfied that the analyses and all work completed 

provide the required safety margin. When the inspection is completed, the inspectors will meet in 

a public setting near the plant to discuss their preliminary findings. The team will also issue a 

written report, available to the public, several weeks after the completion of the inspection.
