Inspection Report No. 80-08 TXX-3142 Page 2 APPENDIX A NOTICE OF VIOLATION Based on the results of an NRC inspection conducted during March 1980, it appears that certain of your activities were not conducted in full compliance with the conditions of your NRC Construction Permits No. CPPR-126 and 127 as indicated below:

Failure to Follow Procedures for Reporting and Repair of Damaged Electrical Cable 10 CFR 50, Appendix B, Criterion V states in part, " Activities affecting quality shall be prescribed by documented instructions, procedures or drawings, of a type appropriate to the circumstances and shall be accom-plished in accordance with these instructions, procedures, or drawings."

Brown and Root Procedure 35-1195-EEI-13, " Repair of Electrical Cable Jacket," requires that damaged cable shall be reported to Electrical Engineering by the craft or by QC via a Field Deficiency Report and requires that damaged jackets on control type cable be repaired using Okonite No. 35 Jacketing Tape in accordance with Okonite Drawing No.

D-5715 when the damage involves penetration through the jacket.

Contrary to the above:

The Resident Reactor Inspection (RRI) learned of a Safety Train A control cable that had been damaged daring pulling of the cable through the buried conduit system from the primary power plant building to the Service Water Intake Building. The cable was pulled back on or about March 28, 1980, and it was verified by the RRI that the damage had been sustained, the jacket was penetrated, and the repair was made with standard vinyl electri- 3 cal tape rather than Okonite No. 35 and not in the method required by  ;

Okonite Drawing No. D-5715. The original damage and initial repair were i not reported via a Field Deficiency Report, j This is an infraction.
