NOTICE OF VIOLATION Southern California Edison Company Docket Nos. 50-361 and 50-362 San Onofre Units 2 and 3 License Nos. NPF-10 and NPF-15 During an NRC inspection conducted from January 11 through January 29, 1993, one violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedures for NRC Enforcement Actions", 10 CFR Part 2, Appendix C, the violation is listed below:
A.
10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Actions,"
states:
"Measures shall be established to assure that conditions adverse to quality, such as... deviations... are promptly identified and corrected."
San Onofre Units 2 and 3 Updated Final Safety Analysis Report (UFSAR),
Section 9.5.4.1, states: "The diesel generator fuel system is designed to ANSI standard N-195."
ANSI standard N-195, Appendix B, "Alternate Calculation of Fuel Oil Storage Capacity," states: "A minimum of 10% is added to the calculated storage requirement if this alternative calculational approach is used."
Contrary to the above, on June 18, 1991, the licensee issued Calculation M-0016-008, Supplement A, "DG Onsite Fuel Oil Requirements" which did not include the 10 percent margin required for determining minimum fuel oil storage capacity even though this error was identified in Inspection Report 50-361, 50-362/89-200, dated January 12, 1990.
Calculation M-0016-008 superseded Calculation M16.4.
Both calculations used ANSI standard N195, Appendix B, methods. The licensee did not correct the 10 percent margin omission until January 25, 1993.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Southern California Edison Company is hereby required to submit a written statement or explanation to the U. S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region V, and a copy to the NRC Resident Inspector at the San Onofre Nuclear Generating Station, within 30 days of the date of the letter transmitting this Notice of Violation (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, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
If an adequate reply is not received within the time specified in this Notice, the Commission may issue 9303120010 930225 PDR ADOCK 05000206 Q
an order or a demand for information as to why the license should not be modified, suspended, or revoked or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.
Dated at Walnut Creek, California this S3 day ofFelrq4ry, 1993.
