ENCLOSURE 1 NOTICE OF VIOLATION t

South Carolina Electric & Gas Docket No.: 50-395 .

V. C. Summer Nuclear Station License No.: NPF-12 During a NRC inspection conducted on May 11 through June 15, 1993, violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violations are listed below: ,

A. Technical Specification 6.8.1.c requires that written procedures be established, implemented and maintained covering the applicable .

procedures recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2. Section 9.a of Appendix "A" states, in part, that

" maintenance that can affect the performance of safety-related equipment should be properly pre-planned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances". Electrical Maintenance Procedure EMP 295.013, Inspection and PM of EFW Pump Motors, provides instruction for lubrication of the emergency feedwater (EFW) pump motor bearings.

Contrary to the above:  !

1) On June 7, 1993, the procedure for the Motor Driven Emergency feedwater Pumps (MDEFW) bearing oil change was inadequate in that  !

it did not specify an acceptable method for refilling the oil reservoir to ensure that the required lube oil level was obtained or that the correct amount of lube oil was added. This resulted 1 in bearing lube oil levels below the pump manufacturers recommended level, and the amount of lube oil added being below the quantity specified in the plant lubrication manual. An ,

evaluation had not been made to justify the lower oil level. i i

2) On May 25, 1993, paragraph 7.5, " Test Run of Equipment" was not I performed following the lubrication of the motor bearing. The  !

failure to perform the applicable steps in paragraph 7.5 resulted  ;

in the excessive grease not being removed from the motor bearings. j During a subsequent operability test of the EFW pump, a high temperature alarm for a motor bearing was received and the test was halted.

This is a severity level IV violation (Supplement 1).

B. Technical Specification 6.8.1.c requires that written procedures be established, implemented and maintained covering the applicable procedures recommended in Appendix "A" of Regulatory Guide 1.33, Revision 2. Section 3.5(2)(b) of Appendix "A" requires procedures for startup, operation and shutdown of the onsite AC electrical system.

Section B of System Operating Procedure SOP-313, local Switchgear Breaker Operations, provides detailed instructions for racking out 480 volt breakers.

South Carolina Electric & Gas 2 Docket No.: 50-395 l V. C. Summer Nuclear Station License No.: NPF-12 i

Contrary to the above, on June 7, 1993, the sequence of steps specified in S0P-313 was not followed when racking out the feeder breaker for auxiliary building exhaust fan XFN 198 because the operators used " skill of the craft" to rack out the breaker rather than referring to the SOP.

! The removal of DC power from the breaker was not documented in the j Danger Tag Log. This contributed to the inadvertent disabling of "B"

! service water booster pump.

This is a Severity Level IV violation (Supplement 1).

Pursuant to the provisions of 10 CFR 2.201, South Carolina Electric & Gas is hereby required to submit a written statement or explanation to the U. S.

Nuclear Regulatory Commission, ATTH: Document Control Desk, Washington, DC 20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector, V. C. Summer Nuclear 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, an order or demand for information may be issued 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.
