NOTICE OF VIOLATION Southern Nuclear Operating Company Docket Nos. 50-348 and 50-364 Farley Nuclear Plant. Units 1 and 2 License Nos.: NPF-2 and NPF-8 During a NRC inspection conducted on July 21 through August 31, 1996, 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) 6.8.1.a requires that applicable written procedures recommended in Appendix A of Regulatory Guide 1.33. Revision

2. dated February 1978, shall be established, implemented, and maintained. Regulatory Guide 1.33. Appendix A. Section 8.b. recommends that specific procedures for surveillance tests should be written for reactor protection system and permissives - tests and calibrations.

Step 5.4 of the Precautions and Limitations of FNP-0-IMP-228.4. Nuclear Instru::,entation System Intermediate Range Compensating Voltage  !

Adjustment, states that compensating voltage should not be adjusted when i plant power descends below the intermediate range scale and source range level is below 100 to 500 counts per second (cps). Step 5.3 also states that once compensating voltage has been adjusted after a shutdown, it should not need readjustment unless the detector characteristics have ,

changed.  !

,,ccv  ;

Contrary to the above, on May 4.1996, t'he Unit 1 nuclear instrumentation system (NIS) intermediate range channel compensating  !

voltage for NI-35 was adjusted by plant technicians even though it was '

below the bottom scale and source range counts were less than 100 cps.

A similar event occurred on January 14. 1995, during the adjustment of Unit 1 NIS intermediate range channel NI-36.

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