.During an NRC inspection conducted on' November 4 through-

December 1, 1987," violations of NRC requirements were identified.

In accordance with the'" General Statement of Policy and Procedure

i

for'NRC' Enforcement Actions," 10 CFR Part.'2, Appendix C.(1987), the'

i

. violations are listed-below:

A.:

Criterion III of Appendix B to 10 CFR Part 50- as implemented

,

by Section 3.0, Revision 3, dated July 31, 1984, of the

j

TU' Electric Quality Assurance Plan (QAP), requires in part,

i

that measures must be established to assure.that applicable

j

regulatory requirements and design bases, as defined in

I

Part 50i2.and as specified in the license application, for

those structures, systems and components to which this

appendix applies, are. correctly translated into specifica-

tions, drawings, procedures, and instructions.

The design

control measures must provide for verifying or checking the

adequacy of design, such as by the performance of design

reviews, by:the use of alternate or simplified calculational

methods, or by the. performance of a suitable testing program.

In addition, design changes, including field changes, must be

,

l

subject to design control measures commensurate with those

applied'to the original design.

Contrary to the above, the NRC inspector identified two

capacitors' connected in parallel with a relay coil located in

both Unit 1 emergency diesel generator control panels that

were not shown on facility electrical drawings nor described

in any associated documents.

i

This is a Severity Level IV violation (Supplement II)

(445/8730-V-06).

B..

Criterion V of Appendix B to 10 CFR Part 50, as implemented by

Section 5.0, Revision.3 of the TU Electric QAP dated July 31,

l-

1984, requires that activities affecting quality shall-be

'

prescribed by and accomplished in accordance with documented

instructions, procedures, or drawings of a type appropriate to

the circumstances.

Paragraph 2.1.3 of TNE Procedure TNE-DC-7, Revision 16,-dated

February 14, 1986, " Preparation and Review of Design

Drawings," requires that completed drawings shall be checked

for accuracy and compliance.

Paragraph 2.1.4 also requires an

engineering review for technical accuracy upon completion of

the drafting / design check.

'

Contrary to the above, drawings were not appropriately

reviewed / checked for accuracy as evidenced by the differences

which existed between the two sets of electrical sc'aematic

drawings for the emergency diesel generator control panels.

Examples of these differences were most evident in the

circuitry for solenoids 6A and 6B and relay contact numbers

and arrangements (i.e., RX/1B and 10X) on Drawings

09-500-76001, Sheet 3 and TNE-El-0067, Sheet 96.

This is a Severity Level IV violation (Supplement II)

(445-8730-V-07).

Pursuant to the provisions of 10 CFR 2.201, TU Electric is hereby

s

required to submit a written statement or explanation to the U.

S.

g

Nuclear Regulatory Commission, ATTN: Document Control Desk,

Washington, DC

20555 with a copy to the Assistant Director for

Inspection Programs, Comanche Peak Project Division, Office of

Special Projects, within 30 days of the date of the letter

I

transmitting this Notice.

This reply should be clearly marked as a

" Reply to a Notice of Violation" and should include for each

violation:

(1) the reason for the violation if admitted, (2) the

action as may be proper should not be taken.

Consideration may be

given to extending the response time for good cause shown.
