Geometry And Design Parameters Adopted by the TVA

Secondary Containment. This category I reinforced concrete structures consists of a cylinder wall having a 162 ft, (49.37 m), inside diameter which is 

Note C . The typical dome tendon spacing is 978 mm measure horiz the final prestressing force for each tendon group is 5453.25 KN/m. 

Purpose of this structure is to minimize off-site radiation dosage which might occur during certain atmospheric conditions. The structure also serves to protect the mechanical and electrical systems, which pass through the annulus enroute to the Auxiliary Building, from catastrophic effects of earthquake, tornado, and flood. 

SHOWING HOOP TENDON ARRANGEMENT UNIT 1 AS SHOWN UNIT 2 OPP HAND 

The TV A structure has been sealed with PVC seals to prevent ingress of water at construction joints below El 625.0. PVC seals shall also be provided across the expansion joints at the bottom slabs and the exterior walls of the Auxiliary Building. The seals into exterior walls shall extend to El 646.5.
