NOTICE OF VIOLATION Southern Nuclear Operating Company, Inc. Docket Nos. 50 424 and 50-425 Vogtle Electric Generating Piant License Nos, NPF-68 and NPF-81 8fnits 1 and 2 During an NRC inspection conducted November 2 through December 13, 1997, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions." (NUREG 1600),

the violation is listed below:

Technical Specification (TS) Surveillance Requirement (SR) 3.3.1.4, Reactor Trip System Instrumentation, requires that a 31-day staggered Trip Actuation Device Operability Test (TAD 0T) be performed to verify that the reactor trip breaker and bypass breaker auxiliary and cell switch contacts, used as P-4 interlock, provide the initiation signal to Solid State Protection System (SSPS) and turbine Electrohydraulic Control (EHC) systems.

Procedures 14420-1 " Solid State Protection System and Reactor Trip Breaker Train A Operability Test.' Revision (Rev.) 27: 14420-2, ' Solid State Protection System and Reactor Trip Breaker Train A Operability Test." Rev. 19: 14421-1. " Solid State Protection System and Reactor Trip Breaker Train B Operability Test." Rev. 8: and 14421-2, ' Solid State Protection System and Reactor Trip Breaker Train B Operability Test."

Rev 6, provide the necessary guidance to perform tne 31-day staggered test.

TS SR 3.3.2.9, Engineered Safety Feature Actuation System Instrumentation, requires that an 18-month TADOT be performed to verify that the P-4 issignal is generated for both the SSPS and EHC systems.

This test verifies that the P-4 signal is generated from both the reactor trip and bypass breakers.

Procedure 14752-1 " Reactor Trip System P-4 Interlock Test," Rev. 4: and 14752 2, " Reactor Trip System P-4 Interlock Test," Rev. 4. provide the test method to verify that the P-4 signal is generated to SSPS from the reactor tri) and bypass breakers. In addition. Procedures 14752-1/2 test that tie P-4 signal is generated to the EHC from the reactor trip breaker.

Contrary to the above, since initial startup of both Units 1 and 2.

Procedures 14420-1/2 and 14421-1/2 were inadequate, in that, they failed to test all auxiliary and cell switch contacts of the reactor trip and bypass breakers in accordance with TS SR 3.3.1.4. Additionally.

Procedures 14752-1/2 were inadequate. in that, they failed to test the P-4 signal generated to the EHC system from the reactor trip bypass breakers in accordance with TS SR 3.3.2.9.

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