APPENDIX B NOTICE OF DEVIATION Duquesne Light Campany Docket No. 50-334 Beaver Valley Power Station, Unit 1 License No. DPR-66 As a result of the inspection conducted on March 11 thru April 18, 1986, and in accordance with the " General' Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the following deviation was identified:
FSAR Appendix B, Seismic Design, Section B.2.2.4, Specification Requirements, states that all Seismic Class I equipment will be shown to meet the require-ments for Operational and Design Bases Earthquakes. For such an event, stress levels are kept within maximum working limits permitted under applicable de-sign standards, or other codes or specifications.
FSAR Table B.1-1, Structures and Systems Requiring Design for Seismic Loading, identifies the emergency diesel fuel oil day tanks as Seismic Class I com-
.ponents.
Contrary to the above, on March 26, 1986, the licensee could not demonstrate that any applicable design standard, code or specification had been employed during the fabrication of the fuel oil day tank support stands as evidenced by incomplete and poor quality welds, and lack of any QC inspection records.
This is a Deviation (Supplement II).
Pursuant to the provisions of 10 CFR 2.201, Duquesne Light Company is hereby re-quired to submit to this Office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including (1) the corrective steps which have been taken and the results achieved; (2) the corrective steps which will be taken to avoid further deviations and (3) the date when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending this response time.
