A prestressing steel tendon was designed and used for vertical prestressing of the containment. It consisted of six high strength steel bars within a galvanized steel pipe. The tendon was shop assembled with minimum field assembly required. Procedures were developed to protect the tendon from corrosion during a lengthy field construction period and a special portland cement grout mix was developed for final grouting. The entire 150 foot high tendon was grouted once after tests showed the procedures to be successful. The paper describes the containment, the structural function of the tendons, tests which were run on tendon materials and hardware, erection of the tendons, stressing and grouting of the tendons.
