1 ENCLOSURE 1 j NOTICE OF VIOLATION South Carolina Electric & Gas Docket No. 50-395  !

V. C. Summer Nuclear Station License No. NPF-12 During a NRC inspection conducted on June 16 through July 31, 1993, a -

violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, i Appendix C, the violation is listed below: ,

Technical Specification 3.3.2 requires that the engineered safety feature actuation system instrumentation channels and interlocks shown on Table 3.3-3 i be operable. Item 3.c.2 of Table 3.3-3 requires that a minimum of two channels for isolation of containment purge and exhaust on a high containment radioactivity signal be operable. Action 17 of Table 3.3-3 allows continued operation with one less channel than the minimum, provided the containment purge supply and exhaust valves are maintained closed. -

i Initial Condition 1.8 of System Operating Procedure S0P-ll4, Reactor Building Ventilation System, requires that containment activity monitor RM-A2 be operable for reactor building normal pressure control activities. This requirement is specified due to normal pressure control activities requiring the opening of containment purge valves. ,

Contrary to the above, on June 28, 1993, the six inch containment purge supply L valves were opened for containment pressure control while RM-A2 was out of  ;

service. The operator who opened the purge supply valves did not refer to SOP-ll4 prior to or during the containment pressure control activity.

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, ATTN: 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 I should be clearly marked as a " Reply to a Notice of Violation" and should i include for each violation: (1) the reason for the violation, or, if i contested, the basis for disputing the violation, (2) the corrective steps  !

that have been taken and the results achieved, (3) the corrective steps that I 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 j 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 I 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 Atlanta, Georgia this 12th day of August 1993 9308300241 930812 'T
