i FINAL REPORT - DER 81-53 DEFICIENCY EVALUATION 50.55(e)

ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNIT 1 I. Description of Deficiency During a termination walkdown inspection, the Main Control Panel wiring was found to be in violation of IEEE-384-1974.

e NCR EC-1669 identifies Comsip, Incorporated installed internal wiring which has bundled Class IE wires (red and green) with Non-Class lE wires (black) . This par-ticular condition, however, is attributed to the Bechtel installation of Foxboro Miniature Records and shelf after Panel B06 had been delivered to the jobsite.

e NCR EC-1668 identifies several termination / routing conditions completed by Bechtel Construction in violation of separation requirements. This condition was discovered when the wiring was inspected to a later revision of the Installation Speci-fication 13-EM-306. Revision 5 of this Specification clari-fled separation and routing requirements for these particular applications.

II. Analysis of Safety Implications This condition is evaluated as Reportable under the requirements of 10CFR50.55(e). Electrical isolation and separation were inade-quate to assure that failure in one circuit would not cause failure in an adjacent safety-related circuit.

l l

l i III. Corrective Action i

NCR EC-1669 will be dispositioned to provide the addition of a barrier as directed by letter Comsip, ' Incorporated #AR-1229, dated March 23, 1982, copy attached.

l Installation Specification 13-EM-306, Revision 5, was issued on l October 7, 1981. This revision provides additional instruction and direction for compliance to IEEE-384-1974. Compliance with this Specification will preclude recurrence for Units 2 and 3.

This will inform you that E*.agineering has performed a field walkdown to inspect Electrical Separation Problems in Unit 1 Main Control Boards as a result of Field Memo RE-056, dated October 14, 1981.

, Project criteria for wire / cable safety separation is based on meeting Regulatory Guide 1.75 and is noted specifically in Specification 13-EM-306, Section 11.0. A minimum of six (6) inches between redundant Class IE field cables or internal redundant Class IE wirir.g is required when relying on air separation. The safety separation may be reduced to one (1) inch (wire to barrier) if acceptable barriers are utilized. Please be advised that as a result of the field inspection, non-compliances to this criteria were discovered.

To date, only an advance copy of NCR EC-1668, which addresses separation in Main Control Boards but doesn't include all the non-compliances cited during the field walk, has been received by Engineering. Specifics determined at the time of walkdown are enclosed for your information with Electrical's input provided to aid in determining formal dispositions. For cases where separation non-conformances have not been included in NCRs written to date it is suggested that the field perform the necessary modifications with consent of vendor in order to fix the separation deficiencies or issue appropriate NCRs for specific dispositioning.

We would also like to advise that special precautions be taken to avoid similar separation problems in Units 2 and 3 implemen-tations.
