FINAL REPORT - DER 83-45 DEFICIENCY EVALUATION 50.55(e)
ARIZONA PUBLIC SERVICE COMPANY (APS)
PVNGS UNIT 1,~ 2 and 3 I.
DESCRIPTION OF DEFICIENCY During startup testing of Unit 1 some of the class IE panels were found to be in violation of separation requirements for field cabling within enclosures per construction specification 13-EM-306
- section 11.0.
The conditions occurred during incorporation of modifications within the panels by Bechtel and APS. The reason is attributed to not having and/or implementing specific construction, start up, and maintenance procedures in regard to separation requirements.
DER 81-53 identified and corrected a similar condition in 1982. As a result of DER 81-53, specification 13-EM-306 Revision 5 was issued to provide revised and clarified separation criteria. At that time, Engineering coordinated the corrective action as documented by 10M-E-9637 and NCR EC-1668 to bring the main control panels into full compliance; however, due to oversights, the clarified specification requirements were not promulgated into the working procedures used by construction, startup, and the station maintenance department.
Subsequently, all safety related cabinets in Unit I were inspected for separation requirements on a case by case basis, and the NCR's were issued for cabinets found in violation of separation requirements and the respective NCR's are listed below:
NCR NO.

ANALYSIS OF SAFETY IMPLICATIONS This condition is evaluated as reportable under the requirements of 10CFR50.55(e). Extensive instances have been identified where electrical isolation and physical separation were inadequate to provide compliance with separation criteria requirements.
Therefore, this condition is evaluated as safety significant.
In addition, this condition is considered as reportable under the requirements of 10CFR Part 21.
III. CORRECTIVE ACTION a) NCR's listed in Section I of this DER will be dispositioned to provide compliance with separation requirements of construction specification 13-EH-306 Section 11.
b) Construction WPP/QCI 255.0, APS start-up procedure. ADIOS and APS maintenance procedure 30AC-9ZZ01 have been revised to specifically reference construction specification 13-EM-306 for separation criteria requirements to preclude recurrence.
c) As documented by APS Corrective Action Request S-83-184-N the respective Engineering, Construction, Startup, Operations, and Quality Control Managers have reviewed this condition and will take action to preclude recurrence. This DER also completes the corrective action required for APS Corrective Action Request C83-94N.
d) Separate inspections for Units 2 and 3 will be scheduled prior to Fuel Load in each unit to identify and correct any cabling separation requirements not in compliance with specification EM-306.
All future nonconformance reports generated as a resuit of these activities will reference this DER.

This will inform you that Engineering has performed a field walkdown to inspect Electrical Separation Problems in Unit I h in Control Boards as a result of Field h uo 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 1E wiring is required when relying on air separation. The safety separation may be reduced to one (1) inch (wire to barrier) if acceptable barriers are utilised. Please be advised that as a result of the field inspection, non-compliances to this criteria l
were discovered.
To date, only an advance copy of NCR EC-1668, which addresses separation in hin Control Boards but doesn't include all the nor.-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.

Dear John:
Meetings have been held with Bechtel Engineering, Bechtel Construction, APS Startup, APS Maintenance and APS Startup QA to discuss the subject CAR. The following corrective action is necessary to address field cabling separation within enclosures:
1)
Bechtel Construction Procedures WPP/QCI 255.0, Rev. 12,
- Cable Terminations," refers to Engineering Specification 13-h 306, " Installation Specification for Cable Splicing,
.Temination and Supports." Specification 13-DF306 in Section 11.0 sets forth the separation requirements for field cabling within enclosures.
'Ibese separation requirements are naaa by Construction QC when inspect-ing lE cable terminations and the Field Engineer when inspecting Non-lE cable teminations. Construction has given extensive training on this subject and in their judgnent farther training is not necessary.
In order to put additional emphasis on field cabling separation within enclosures, WPP/QCI 255.0 will be revised to specifically refer to 13-W306 for separation requirements. 'Ihis procedure revision will be issued by June 1, 1983.

2)
APS Startup Procedures Startup Procedure AD-105, "Startup Nbrk Permit," will be revised to reference WPP/QCI 255.0 and Specification 13-D5-306 for field cabling separation within enclosures.
Rese separation requirements will be used by Startup QC when inspecting IE cable terminations and the Startup Engineer when inspecting Non-lE cable terminations.
his procedure revision will be issued by June 1,1983, and training will be given to the affected personnel by July 1, 1983.
3)
APS Maintenance Procedures Work Control Procedure 30AC-9ZZ01 will be revised to reference Speci-fication 13-Di-306 for field cabling separation requirements within enclosures. m is procedure revision will be issued by June 1, 1983, and training will be given to the affected personnel by July 1, 1983.
4)
Field Cabling Separation Verification Within Enclosures Since the foregoing organizations have been doing wiring and termination work within safety-related panels and separation problems are evident; a program is being developed by Engineering to audit Unit 1 safety-related panels using the requirements of Specification 13-Ei-306.
The audit team will be led by Engineering with assistance frcm Startup and Startup QC personnel.
The program will be emplete by June 15, 1983, and the separation audit / corrections will be cmplete before fuel load.
A similar audit is planned for Units 2 and 3 after the associated panel j
modification work is capleted.
Please advise me if you have any questions or ccrments on this response.
