NOTICE OF VIOLATION

-Houiton Lighting & Power' Company Dockets: 50-498

'LSouth' Texas Project,- Units 1 and 2 50-499 Pennits: CPPR 128 CPPR 129 During this NRC inspection conducted on June 1 through August 30, 1986, two violations of NRC requirements were identified. The violations involved failure to follow storage requirements of hanger supports and failure to follow procedures / specifications. In accordance with the " General Statement of Policy

- and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986),

the violations are listed below:

A. Failure to Follow Storage Requirements Criterion XIII of Appendix B to 10 CFR 50, states, in part, that measures shall be established to control the handling and storage of material and equipment in accordance with work and inspection instructions to prevent damage or deterioration. This requirement is amplified by the approved Quality Assurance Plan Description (QAPD) for the South Texas Project.

Bechtel .cnecification 5A300GS1002, Revision 8, " Storage Requirements for STPEGS ' .ety-Related Engineered Equipment," paragraph 4.6 states, in part, that the subject items are.to be protected against the elements and physical damage.

Contrary to the above, in the Unit 2 laydown area, several NPS manufactured pipe support sway struts were observed to exhibit rusting and corrosion on the paddle end bearings to the point of being unusable for their intented application.

This is a Severity Level IV violation. (10CFRPart2,SupplementI.E)

(499/8621-01)

B. Failure to Follow Procedures Criteria V of Appendix.B to 10 CFR Part 50, requires activities affecting quality be prescribed by and accomplished in accordance with appropriate instructions, procedures, or drawings. This requirement is amplified by the approvad QAPD for South Texas Project. The following are examples of failures to meet this requirement.

1. SSP-9.0, Revision 4, paragraph 5.2.7.3 states, "that all work on permanent or temporary supports which are released for test shall require a Startup Work Request (SWR) before any work can be performed."

t 2

Contrary to the above, construction craft removed the main steam piping temporary supports in Isolation Valve Cubicals (IVC) A snd C without an SWR which resulted in an overload condition of the main steam line.

2. Specification SL340JS1002, Revision 10, paragraph 5.4.4.5 states, in part, that deviations in the actual cold position are permitted to account for slight imbalance. The constructor shall check / verify to assure that this deviation will not result in bottoming out or topping out of the spring hangers due to thermal or seismic movements of the pipe.

Contrary-to the above, construction craft did not check / verify the main steam (MS) line in Unit 1 IVC A and C after hydrostatic testing resulting .in the bottoming out of spring hangers MS1001-HL5013 and MS1003-HL5018.

3. Specification SL340JS1002, Revision 10, paragraph 5.4.4.7 states

" travel stops in variable springs may be removed, as directed by engineering, to facilitate system testing."

Contrary to the above, travel stops in variable spring hangers MS1001-HL5013 and MS1003-HL5018 were removed without approval from engineering.

This is a Severity Level IV violation. (10 CFR Part 2, Supplement I.E)

(498/8623-02)

Pursuant to the provisions of 10 CFR 2.201, Houston Lighting & Power Company is hereby required to submit, except as noted below, 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 reason for the violation if admitted, (2) the corrective steps which have been taken and the results achieved, (3) corrective steps which will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
