L APPENDIX A NOTICE OF VIOLATION Houston Lighting & Power Company Dockets: 50-498 South Texas Project (STP), Units 1 and 2 50-499 Operating Licenses: NPF-76 e NPF-80 i

During an NRC inspection conducted April 1-30, 1989, a violation of NRC requirements was identified. The violation involved the failure of the licensee to properly environmentally qualify the application of eight auxiliary feedwater valves. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1988), the violation is listed below:

10 CFR 50.49, pr.agraph (f) requires that (environmental) qualification of -

each component must be based on testing or experience with identical equipment, or with similar equipment with a supporting analysis, to show that the equipment to be qualified is acceptable.

Paragraph (k) of 10 CFR 50.49 states that equipment previously required by the Commission to be qualified to NUREG-0588, " Interim Staff Position on Environmental Qualification of Safety-Related Electrical Equipment," need not be requalified.

Paragraph 5(1) of NUREG-0588 states that the qualification documentation shall verify that each type of electrical equipment is qualified for its application and meets its specified performance requirements. The basis of qualification shall be explained to show the relationship of all facets of proof needed to support adequacy of the complete equipment. Data used to demonstrate the qualification of the equipment shall be pertinent to the application and organized in an auditable form.

Contrary to the above, the equipment qualification file, which contained Wyle Laboratories Report No. 47664-05, " Assessment Report on Limitorque Operators For Use in South Texas Nuclear Power Plant," for eight auxiliary feedwater valves with space heaters installed and energized, did not support qualification. This was due to the failure to analyze all possible effects of energized space heaters used within the motor operator. No analyses were contained in the files to fully establish qualification for air temperature rises of cables, wires, splices, and components resulting from their proximity to the heaters.

This is a Severity Level IV violation. (Supplements)(498/8911-01; 499/8911-01) i Pursuant to the provisions of 10 CFR 2.201, Houston Lighting & Power Company is 1 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 reason for the violation if admitted, 8906140237 890607 PDR ADOCK 05000498 Q FDC
