On June 23. 1985, during a post maintenance review of a maintenance request used to repair the DG battery rack stud, it was detennined that the weld repair procedure used was not suitable for the welding of American Society for Testing and Materials (ASTM) A-307 material.
Subsequent investigations discovered the stud material used on the battery racks was not ASTM A-307 material but ASTM A-325 material which is not suitable for welding by TVA procedures. . The DGs were declared inoperable on September 24, 1985, because of the battery rack studs seismic concerns and an unrelated surveillance problem (LER 259/85041). The DG battery racks were brought into a seismically qualified configuration by installation of studs made of a material qualified for the application.
