Nuclear Regulatory Commission l Washington, D. C. 20555 Attention: Mr. S. A. V? rga Joseph M. Farlt:y Nuclear Plant - Units 1 and 2 Meteorological Monitorir.g Technical Specification Change Gentlemen:

As agreed to during the Farley Nuclear Plant - Unit 2 licensing process, Alabama Power Company installed a backup meteorological monitoring tower. The current Farley Nuclear Plant Technical Specifications do not address the backup tower such that f ailure of the primary meteorological tower is conside sd total loss of technical specification monitoring capability. The proposed change to the technical specifications is to incorporate the backup tower into the tables of allowable meteorological monitoring instrumentation.

The existing requirement of Technical Specification 3/4.3.3.4 is: with one or more required meteorological monitoring channels inoperable for more than 7 days, submit a report to the NRC. The l required monitoring channels are 1 of 2 primary tower channels each for wind speed and wind direction. The two primary meteorological monitoring tower channels are listed in Tables 3.3-8 and 4.3-5.

The redundant backup tower, which includes an additional channel of monitoring instrumentation for both wind speed and wind direction, is not mentioned in the technical specifications.

The proposed change to the technical specifications adds the backup monitoring instrumentation to Tables 3.3-8 and 4.3-5 such that the minimum operable requirement would be 1 of 3 channels rather than 1 of 2 channels. This change would increase the ,gg - d-availability of the meteorological monitoring instrumentation and would tend to reduce the number of reports submitted to the NRC.

l Mr. S. A. Varga January 24, 1983 U. S. Nucle.ar Regulatory Commission Page 2 Alabama Power Company's Plant Operations Review Committee has reviewed this proposeo change to the technical specifications and has determined that the change does not involve an unreviewed saf ety question as shown in Attachment 1. The proposed changes to the technical specification pages are included in Attachment 2.

The Nuclear Operations Review Board will review this change at a future meeting.

The class of this proposed amendment is des.ignated as Class III for Unit 1 and Class I for Unit 2 according to 10 CFR 170.22 requirements. Enclosed is a check for $4,400 to cover the total amount of fees required.

NRC approval of this proposed change is requested by August 1, 1983.

In accordance with 10 CFR 50.30(c)(1)(i), three signed originals and forty (40) additional copies of this proposed change dre enclosed.

Yours very truly,

1 ATTACHMENT 1 SAFETY EVALUATION FOR THE PROPOSr.D CHANCE TO TECHNICAL SPECIFICATION 3/4.3.3.4 I. BACKGROUND As agreed to during the Farley Nuclear Plant - Unit 2 licensing process, Alabama Power Company installed a backup meteorological monitoring tower. The current Farley Nuclear Plant Technical Specifications do not address the backup tower such that failure of the primary meteorological tower is considered total loss of technical specification monitoring capability. The proposed change to the technical specifications is to incorporate the backup tower into the tables of allowable meteorological monitoring instrumentation.

II. REFERENCES FNP Unit 1 Technical Specification 3/4.3.3.4 FNP Unit 2 Technical Specification 3/4.3.3.4 III. BASES The existing Farley Nuclear Plant Technical Specifications are based on the original plant design which included only one meteorological monitoring tower. However, as a result of the licensing process for Unit 2, a backup meteorological moni-toring tower was installed. The backup tower wind speed and wind direction instrumentation are equivalent to the original or primary tower instrumentation but were never incorporated into the technical specifications.

The existing requirement of Technical Specification 3/4.3.3.4 is: with one or more required meteorological monitoring channels inoperable for more than 7 days, submit a report to the NRC. The required monitoring channels are 1 of 2 primary tower channels each for wind speed and wind direction. The two primary meteorological monitoring tower channels are listed in Tables 3.3-8 and 4,3-5. The redundant backup tower, which includes an additional channel of monitoring instrumentation for both wind speed and wind direction, is not mentioned in the technical specifications.

ATTACHMENT 1 Page 2 The proposed change to the technical specifications is to add the backup monitoring instrumentation to Tables 3.3-8 and

4.3-5 such that the minimum operable requirement would be 1 of 3 channels rather than 1 of 2 channels. This change would increase the availability of the meteorological monitoring instrumer,tation and would tend to reduce the number of reports submitted to the NRC.

IV. CONCLUSION The proposed changes to the Unit 1 and Unit 2 Technical Specifications do not involve an unreviewed safety question as ,

i defined by 10 CFR 50.59. The proposed change would increase

, the overall plant safety by increasing the availability of a ,

required monitoring system. l 1
