Project description
In the course of a routine seismic review, strengthening of the emergency feed building at Gösgen nuclear power station was found to be necessary. As a secondary measure, the four cooling water (deionate) tanks had to be strengthened as these structures also did not now meet current standards.
Solution
Post-tensioned, chemically resistant CFRP plates were specified as the strengthening system. They could be installed in a very short time, with the ends transferring the post-tensioning force through concentrated end anchors into the cross walls. Quality control of the CFRP plates had top priority and every tendon was tested to a post-tensioning force of 110% at the production facility before being installed on the structure.
