e APPENDIX A NOTICE OF VIOLATION Texas Utilities Electric Company Dockets: 50-445/86-06 50-446/86-04 Comanche Peak Steam Electric Permits: CPPR-126 Station, Units 1 and 2 CPPR-127 During an NRC inspection conducted on February 1 through March 31, 1986, two violations of NRC requirements were identified. The violations involved procedural inadequacies and work practices associated with cable installations, and absence of cable support grips at the top of vertical raceways. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the violations are listed below:

A. Criterion V of Appendix B to 10 CFR Part 50, as implemented by Section 5.0, Revision 3, dated July 31, 1984, of the TUGCo QA Plan (QAP),

requires that activities affecting quality shall be prescribed by and accomplished in accordance with documented instructions, procedures, or drawings.

Paragraph 4.2.2.3.a of Gibbs and Hill (G&H) Specification 2323-ES-100, Revision 2, " Electrical Erection," states, in part, "All cables and individual conductors shall be installed in a workmanlike manner. Cables shall be neatly trained, without interlacing, in all cable trays, trenches boxes and panels . . . ." Paragraph 4.2.2.4 of this specification states, in part, " Cables in cable trays . . . shall be laid therein whenever possible. Cable in trays shall be laid to a uniform depth."

Contrary to the above:

1. TUGCo Instru . tion QI-QP-11.3-26, Revision 24, dated October 11, 1985,

" Electrical Cable Installation Inspection," did not address specification requirements with respect to workmanlike installation, training of cables without interlacing, or installation of cables to a uniform depth. Also, Brown and Root (B&R) Procedure EEI-7, Revision 6, dated March 26, 1986, " Cable Pulling," did not address installation of cables in trays to a uniform depth.

2. Cables were observed to be spilling over the side rails of cable trays T240SF003, 004, 005, 006, 007, 008, and T240SDA91. Cables were also not laid in the tray at the vertical to horizontal transition between cable tray sections T240SF003 and T240SF004.

This is a Severity Level IV violation (Supplement II) (446/8604-V-02).

B. Criterion V of Appendix B to 10 CFR Part 50, as implemented by Section 5.0, Revision 3, dated July 31, 1984, of the TUGCo QAP, requires g90gh h p o i

2 that activities affecting quality shall be prescribed by and accomplished in accordance with documented instructions, procedures, or drawings.

Paragraph 4.2.1.5.b(2) of G&H Specification 2323-ES-100,~ Revision 2 requires that a cable support be provided as close as practicable to the top of a vertical raceway, for No. 18 through No. O conductor sizes, when '

the vertical riser length is 25 feet or greater.

Paragraph 3.11.3.a of TUGCo Instruction QI-QP-11.3-26, Revision 24, and paragraph 3.1 of B&R Procedure EEI 23, Revision 1, dated July 21, 1983,

" Cable Support Grip Installation," reflect the above specification requirements.

Contrary to the above, cable support grips were not evident on cables (with conductors in the above size range) installed in cable tray risers containing tray sections T23GECX91 and T24GEDG98 that were greater than 25 feet in height.

This is a Severity Level IV violation (Supplement II) (446/8604-V-03).

Pursuant to the provisions of 10 CFR 2.201, Texas Utilities Electric Company is hereby required to submit to this office, within 30 days of the date of the letter transmitting this Notice, a written statement or explanation in reply, including for each violation: (1) the reasons for the violations if admitted, the corrective steps which have been taken and the results achieved.

l the corrective steps which will be taken to avoid further violations, and i the date when full compliance will be achieved. Where good cause is shown, consideration may be given to extending your response time.
