'FSAR Appendix -9.5A Section C.2 states that the design,. installation, inspection and tests associated with the fire protection systems are accomplished in accordance with written and approved instructions, procedures and drawings. TVA Drawing 3AWO910-00-01 Note 29 states that the fire dampers and sleeve assemblies for fire barrier penetrations will be installed per vendor installations and "SMACNA" standards. The vendor's fire damper documents require the dampers to be attached to the damper sleeve by welds, bolts, screws or rivets spaced not more than 8-inches on
