Ladies and Gentlemen:

In accordance with the provisions of 10 CFR 50.90, Southern Nuclear Operating Company (SNC) proposes to amend the Farley Unit I and Unit 2 Technical Specifications

- (TS) to relocate the Seismic and Meteorological Monitoring Instrumentation from the TS to the Final Safety Analysis Report (FSAR). The proposed changes are consistent with the NRC " Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors" dated July 22,1993. Accordingly, the seismic and meteorological monitoring instrumentation will be relocated to the FSAR. Compliance with 10 CFR 50.59 and applicable regulatory guidance will ensure acceptable seismic and meteorological monitoring instmmentation performance is maintained.

This change will facilitate more efficient use of NRC and SNC resources by allowing future installation of replacement instmmentation without the need for a License -

Amendment. For example, the presently installed seismic recording instrumentation is --

scheduled for replacement. Available replacements offer superior performance, including accuracy. However, the performance parameters for the proposed replacement equipment vary from those detailed in the existing TS. Relocation of the instruments to the FSAR will allow evaluation of such changes via 10 CFR 50.59. In order to facilitate the presently planned seismic instrumentation replacements, NRC approval is requested by May 15,1995.

, r ENCLOSURE 2 Joseph M. Farley Nuclear Plant Request to Relocate Seismic and Meteorological Instrumentation Technical Specifications to FSAR 10 CFR 50.92 Evaluation

Background

Presently the FNP Unit I and Unit 2 Technical Specifications (TS) contain detailed requirements regarding surveillance and performance characteristics of seismic and meteorological monitoring instrumentation. These requirements are presently located in TS 3/4.3.3.3 and 3/4.3.3.4. SNC proposes to remove the TS requirements and associated Bases for the Seismic and Meteorological Monito ing Instrumentation and relocate the information to the FSAR. This TS change will facilitate future changes to the seismic and meteorological instmmentation under the control of 10 CFR 50.59. For example, SNC presently plans to replace seismic accelerographs in 1995. The new instruments offer superior performance to the presently installed accelerographs and meet all regulatory requirements; however, the range of the accelerographs is outside the range allowed in Table 3.3-7. Rather than revise the existing table, SNC chooses to relocate this information consistent with recent industry and NRC guidance as described below.

! A_nalysis The proposed changes are administrative in nature since the changes are consistent with approved NRC guidance for TS as discussed in detail below. Relocation of the Seismic and Meteorological Monitoring Instmmentation TS will not decrease the effectiveness of l the instmmentation. However, this change will allow SNC to administratively control l changes to the seismic and meteorological monitoring instmmentation in accordance with l the provisions of 10 CFR 50.59.

On July 22,1993, the Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors became effective. According to the Policy Statement, the l

purpose of the TS is to impose those conditions or limitations upon reactor operation  ;

j necessary to obviate the possibility of an abnormal situation or event giving rise to an immediate threat to the public health and safety by identifying those features that are of l

Results 1 j

Southern Nuclear Company (SNC) has reviewed the requirements of 10 CFR 50.92 as they relate to the proposed changes and has made the following determination:

]

1. Does the proposed change involve a significant increase in the probability or .j consequences of an accident previously evaluated?  !

j No. The proposed change relocates information from the TS to the FSAR and has  ;!

no impact on physical plant operation of configuration. The continued capability '!

cf the seismic and meteorological instrumentation to perform its intended function ' l will be ensured through controlled change processes governed by 10 CFR 50.59. j l

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Dows the proposed change create the possibility of a new or different kind of-

, . accident from~ any previously evaluated?

No. The sole function of the seismic and meteorological monitoring .

instrumentation is to record data. - The proposed change will not involve any design change or modification to the plant. . The proposed change will not alter the operation of the plant or the manner in which it is operated. Any subsequent change to the Seismic and Meteorological Monitoring Instrumentation -

requirements .will undergo a review in accordance with the criteria of 10 CFR .

50.59 to endure that the change does not involve an unreviewed safety _ question.-

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

p 3. Does the proposed change involve a significant reduction in a margin of safety?

No. The proposed change will relocate Seismic and Meteorological Monitoring Instmmentation requirements from the TS to licensee controlled documents subject to the criteria of 10 CFR 50.59. The proposed change will have no adverse impact on any protective boundary or safety limit.

Therefore, the proposed change will not involve a significant reduction in a margin ofsafety.

Conclusion  :

i Therefore, SNC has determined the proposed changes meet the requirements of. 1 10 CFR 50.92(c) and do not involve a significant hazards consideration.' l I
