1. Allegation Category: QA/QC 7, QA Implementation

2. Allegation Number: AQ-113

3. Characterization: It is alleged that Texas Utilities Electric Company (TUEC) management lacked commitment to an adequate QA/QC program and that this is reflected by its untimely reporting of ferroresonant transformer failures under 10 CFR 50.55(e) requirements.

4. Assessment of Safety Significance: This allegation identified TUEC's untimely 10 CFR 50.55(e) report to the NRC for the failure of three of the four Unit-1 safety-related inverters as a specific example of TUEC management's lack of commitment to an adequate QA program. The NRC Tech-nical Review Team (TRT) found that the cited Westinghouse instrument power supply inverters failed between February and May of 1983, and that TUEC initiated test deficiency reports (TDRs) and nonconformance reports (NCRs) to document the failures and to obtain replacement equipment from Westinghouse. ,

It was not until January 16, 1984, approximately 11 months after the trans-formers failed, that TUEC made an oral report to the NRC of this failure, thus violating the reporting requirements of 10 CFR 50.55(e). NRC Region IV reported this incident in inspection report (IR) 50-445/84-22 and iden-tified it in a notice of violation. Based on review of TDRs, NCRs, and IR 50-445/84-22, the TRT determined that TUEC did not act promptly, as required by 10 CFR 50.55(e) and by TUEC procedure CP-0P-16.1, Rev. 5, "Significant Construction Deficiencies."

5. Conclusion and Staff Positions: Based on the assessment of TUEC's untimely

, reporting of the ferroresonant transformer failures, the TRT concludes that the allegation is substantiated, and that this violation could indicate a lack of management commitment to an effective QA/QC program. It appears that this particular violation was caused by ineffective procedural imple- -

mentation. This example of ineffective 10 CFR 50.55(e) reporting, which is not an isolated occurrence, has potential generic implications, as noted in QA/QC Category 2, allegation AQ-102. TUEC's procedures for reporting significant construction deficiencies lack specificity.

The alleger has declined further contact with the TRT; therefore, a followup interview was not conducted.
