Delaminated Prestressed Concrete Dome: Investigation and Repair
Publication: Journal of Structural Engineering
Volume 109, Issue 5
Abstract
A description of the discovery of the delamination of the 3‐ft (76‐m) thick concrete dome portion of a nuclear power plant containment. An investigation was made as to the causes of the delamination, the strength of the delaminated structure, and repair techniques. Repairs were made consisting of epoxy injection of cracks in the lower 2 ft (51 m) of the dome, providing radial anchors between the lower portion of the dome and the upper “cap,” the delaminated portion, which was removed and replaced with new concrete.
