Electrical (Components and Systems II) - Review of equality Records The inspector reviewed the records for the batteries listed in paragraph
to assure that the batteries and battery racks were seismically qualified.
The records review for Units 1 and 2, 125 volt D.C. Diesel Generator batteries A, B, C and D was not completed during this inspection.
All seismic qualifi-cation records for these batteries were not reviewed.
This item is identified as Unresolved item 259/79-20-01 and 260/79-20-01; Seismic qualification records for Units 1 and 2 Diesel Generator batteries,.
During the records review for the Unit 3, 125 volt D. C. Diesel Generator batteries 3A, 3B, 3C and 3D, the seismic qualification of the 6-foot battery rack section was questioned.
The records available at the site indicated the 6-foot battery rack section was not seismically qualified.
Discussion with Engineering Design (EN DES) personnel revealed that an engineering evaluation/analysis has been performed and indicates the 6-foot battery rack section is seismically qualified.
Since no seismic documentation was available at the site, the licensee has agreeded to further evaluate this item and provide additional information.
This item is identified as Unre-solved item 296/79-20-01; Seismic qualifications for Unit 3 Diesel Generator's 6-foot battery rack section.
Within the areas examined, no items of noncompliance or deviations were identifie i
