1 FINAL REPORT - DER 83-68 DEFICIENCY EVALUATION 50.55e)
ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNITS 1, 2, & 3 I.
DESCRIPTION OF DEFICIENCY Exide Manual, Log. No. E050-4 5-1, section 58.10, paragraph 4 (a) states in part "All bolts and nuts used to assemble and anchor the battery racks are to be Class 2 fit and SAE Grade 5 or ASTM-449 or better." However, during surveillance inspection of PK and NK Battery Racks in Units 1 and 2 it was determined that the racks were put together with a mixture of specified and non-specified bolts.
Field investigation has determined that Exide supplied the correct F
hardware as per specification requirements; however, this material was subsequently intermixed at the jobsite. The battery racks are identified by the following unit tag numbers:
lE-PKA-FilR 2E-PKA-FilR 3E-PKA-FllR lE-PKB-F12R 2E-PKB-F12R 3E-PKB-F12R lE-PKC-F13R 2E-PKC-F13R 3E-PKC-F13R 1F-PKD-F14R 2E-PKD-F14R 3E-PKD-F14R
- lE-QDN-F0lR
- 2E-QDN-F0lR
- 3E-QDN-F0lR
- lE-QDN-F02R
- 2E-QDN-F02R
- 3E-QDN-F0lR
- Battery racks are Quality Class S, Non Class lE, and hardware must conform to Quality Class y to support seismic qualifications. The battery racks are located in a safety-related area.
II.
ANALYSIS OF SAFETY IMPLICATIONS Bechtel engineering has reviewed the circuit classes of the subject battery racks with the follovirg conclusions:
A.
PK battery racks contain Class lE batteries, are designated Quality Class Q and are essential to the safe operation of the plant.
B.
NK battery racks contain Non-Class IE batteries, are designated Quality Class R and are not essential to the safe operation of the plant.
C.
QDN battery racks contain Non-Class lE batteries, are designated Quality Class S.
Because these racks are close to safety-related equipment the racks require seismic withstand capability during a design basis event (DBE).
Failure of the structural integrity of battery racks PK and QDN is unacceptable.
Based on the above, the condition is evaluated as reportable under the requirement of 10CFR50.55(e), since if this condition were to remain uncorrected, it would represent a safety significant condition. The evaluation of the condition indicates tnat it does not meet the requirements for reportability under 10CFR Part 21.

III. CORRECTIVEi ACTION A..
Non-ccnforming hardware'.will be replaced on Units 1 and 2 PK
. and QDN battery racks, with Class 2 fit, ASTM-449 and/or SAE Grade 5 materials. This work will be done prior to fuel 21oad-of ~ the ' respective units.-
l B.
An' inspectiori ~of Unit 3 PK and QDN battery racks will be -
~
performed. NCR's will be issued if non-conforming conditions.
are found. The corrective action will be the.same as Units 1 and 2 and work shall be completed prior to fuel load for Unit
~
3 t -.t-
.C.
NCR SE-2783 will be dispositioned as " Rework" for PK and QD'!
battery racks, and "Use-As-Is" for NK battery racks.
