U. S. Nuclear Regulatory Commission ATrN: Document Control Desk Washington, DC 20555 Joseph M. Farley Nuclear Plant Clarification of R.G. l.97 Commitment j
Ladies and Gentlemen:
A question has been raised concerning Southern Nuclear Operating Company (SNC) implementation of Regulatory Guide (R.G.) 1.97 commitments for identification of Category I and 2 instruments on the main control board (MCB) at Farley Nuclear Plant (FNP).
1 FNP responded to NRC IE Bulletin 79-06A requirements for ensuring the capability to systematically analyze plant conditions and parameters by placing orange bars on MCB indicators needed during
)
accidents In response to R.G.1.97, Alabama Power Company submitted the Compliance Report to the j
NRC June 29,1984, which included a commitment to use a combination of orange bar designators on certain instruments on the MCB and the emergency operating procedures (EOPs) to meet the intent of i
R.G.1.97 requirements for monitoring accident conditions.
Since this commitment was made, FNP has undergone a change in philosophy due to the development of the Emergency Response Procedures (ERPs) which direct which indications should be used in accident conditions. In addition, it has been determined that identifying which indicators were ensironmentally qualified was more beneficial to the operator than simply marking indicators which were referred to in the ERPs.

l Herefore, the purpose of this letter is to revise the commitment to use orange bars on the MCB at FNP.
SNC has determined that there is no significant benefit to using orange bars to designate Bulletin 79-06A or R.G.1.97 indicators. The ERPs specify which instruments should be used when they are being l
followed. histruments which are environmentally qualified are marked with an "EQ" designator on the MCB. The R.G.1.97 instruments in the previous commitment to have orange bars are now marked l
"EQ" except for the following three instruments: main steam line pressure, refueling water storage tank l
level, and chute storage tank level. Dese three instruments are not located in harsh environments and are specifically identified in the plant ERPs. Consequently, the requirement for orange bars on the MCB at FNP has been deleted.
If you have any questions, please advise.
