NOTICE OF VIOLATION

TU Electric Dockets: 50-445/87-31

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

f or NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1987), the

violations are listed below:

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

Section 5.0, Revision 3 of the TU Electric Quality Assurance

Plan (QAP), states, in part, " Activities affecting quality

shall be prescribed by documented instructions, procedures, or

drawings, or a type appropriate to the circumstances and shall

be accomplished in accordance with these instructions,

procedures, or drawings. . . . "

Section 7.7.1 of Revision 2 to EBASCO's Field Verification

Method (FVM) CPE-EB-FVM-CS-033, states, in'part, "The Walkdown

Engineer will identify each type of support by comparison with

supplement I and/or 2323-S-0910 sketches or drawings, and will

as-built the support on the applicable sketch or

drawing . . . . " Paragraph K of this section of the FVM

further states, "All dimensions and/or attributes shown will

be verified . . . . If the designed dimensions / attributes are

incorrect, they shall be lined out and the actual dimension /

attribute recorded." Further, paragraph N states that the

walkdown engineer will redline ". . . any HKB/HSKB spacing

violation per Table 2."

Contrary to the above, the following conditions were

identified:

1. For support C13OO7808-04, which is a 2323-S-0910

Type CA-la support, the anchor bolts identified as

bolts A, E, and F were lined out. This implied that

anchor bolts did not exist at these locations for'this

unique support. During a subsequent walkdown by the NRC

inspector, however, an anchor bolt was found to exist at

the location designated for anchor bolt A. This bolt was

determined to be a 1/4" Hilti Kwik bolt with the letter

designation "D" and a projection of 1". While the

xistence of this additional anchor bolt Mill not have a

detrimental effect on the structural integrity of the

support, the fact that it was not identified during the

EBASCO walkdown is of significance relative to the-

adequacy of the walkdown itself.

2. On support C14G21398-03 the walkdown engineer failed to

record one of the dimensions required to fully locate the

structural tubing on the base plate. This information is

required in order to calculate base plate stress and

anchor bolt loads. This dimension is one of the

dimensions required to be reported for this type of

l support (2323-S-0910 sh. CSM-18 type support).

3. On support C14B13125-02, Lie walkdown engineer. failed to

note a spacing violation between the 1/4" Hilti Kwik bolt

designated as Bolt F on the support in question, and a

3/8" HKB on an adjacent conduit support. The NRC

inspector found these anchor bolts to be 2 1/4" apart; j

while the FVM required a spacing of at least 3 1/8".

This is a Severity Level V violation (Supplement II)

(445/8731-V-01). -

B. Criterion XVI of Appendix B to 10 CFR Part 50, as implemented

by Section 16.0, Revision 0, of the TU Electric QAP, states,

in part, " Measures shall be established to assure that-

conditions adverse to quality . . . are promptly identified

and corrected . . . and corrective action taken to preclude

repetition." .!

l Nuclear Engineering and Operation Procedure NEO 3.06,

" Reporting and Control of Deficiencies," requires deficiencies

(principally programmatic and not directly related to hardware i

problems) to be identified,'the cause established, and action  !

, taken to prevent repetition. I'

Contrary to the above, the " rework" dispositions of NCRs

I-85-101890SX and C-86-200378X were incorrectly revised to

"Use-As-Is" dispositions, subsequent to engineering becoming

aware that the conditions which created the need for the NCRs

had been corrected outside of the scope and control of the

NCRs. By revising the dispositions and closing out the NCRs,

actions were not taken to determine the cause of the

deficiency (uncontrolled work) or to prevent repetition.

This is a Severity Level IV violation (supplement II)

(445/8731-V-02; 446/8723-V-01).

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

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

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

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 <

corrective steps that have been taken and the results achieved,

(3) the corrective ateps that will be taken to avoid further

violations, and (4) the date when full compliance will be achieved.
