V0GTLE ELECTRIC GENERATING PLANT RfVIS10's! 0F TECHNICAL SPECIFICATIONS REFERENCES TO FIGURES 3.1-2 AND 3.1-3 In accordance with the provisions of 10 CFR 50.90 and 10 CFR 50.59, Georgia Power Company (GPC) hereby proposes to amend the Vogtle Electric Generating Plant (VEGF) Units 1 and 2 Tecinical Specifications, Appendix A to Operating Licenses NPF-68 and NPF-81.

On July 30, 1990, the na issued Amendment Number 32 and Amendment Number 12 to the licenses for VEGP Units 1 and 2. These amendments consisted of changes to the Technical Specifications in response to GPC's request dated March 22, 1990.

The amendments removed limits associated with reactor physics that are fuel-cycle specific and placed them in a separate Core Operating Limits Report (COLR). A part of that change resulted in removing Figures 3.1-2 and 3.1-3 from ths Technical Specifications and plccing them in the COLR. Currently, the Acti statements for Specifications 3.4.2.2, 3.1.2.4, and 3.1.2.6 refer to Figure 3.1-2, and Bases sections 3/4.2.2 and 3/4.2.3 refer to Figure 3.1-3.

This proposed revision to t.1e Technical Specifications will replace those references with appropriate references.

The proposed change and its basis are described in Enclosure 1. An evaluation pursuant to 10 CFR 50.92 showing that the proposed changes do not involve significant hazards considerations is provided as Enclosure 2. Instructions for incorporation of the proposed changes into the Technical Specifications and a markup of the affected pages are provided as Enclosure 3.

In accordann with 10 CFR 50.91, the desirated state official will be sent a copy of this letter and all enclosures, g4020300910329 p ADOCK 05000424

roposed Chanae The proposed change will replace the >hrase "...SHVTDOWN MARGIN as required by Figure 3.1-2 at 2000F....' with the parase "... SHUTDOWN MARGIN as specified in the CORE OPERATING LIMITS REPORT for MODE 5 at 2000F...." in Action statements for Specifications 3.1.2.2, 3.1.2.4, and 3.1.2.6. It will also replace the phrase "as defined by figure 3.1-3." by the phrase "...as described in Specifiestion 3.1.3.6;" in Bases section 3/4.2.2 and 3/4.2.3.

Ibuit Georgia Power Company letter ELV-01266 dated March 22, 1990, proposed to revise tha Technical Specifications by removing reactor physics data that is cycle specific and placing it into a Core Operating Limits Report. Thisfchange to the Technical Specifications was issued as Amendment Number 32 and Amendment Number i 12 to the VEGP Operating Licenses. Figure 3.1-2 which provides shutdown margin requirements far Node 5 was removed from the Technical Specifications and placed in the COLR. Figure 3.1-3 which provides control rod bank -insertion limits was also removed *om the Technical Specifications and placed in the COLR. =The current Techn. il-Specifications continue-to refer to Figures 3.1-2 and 3.1-3.

This change coirects the references to Figures 3.1-2 and 3.1-3_by replacing them with appropriate references, t

ENCLOSURE 2 V0GTLE ELECTRIC GENERATING PLANT REVISION OF TECHNICAL SPECIFICATIONS REFERENCES TO FIGURES 3.1-2 AND 3.1-3 10 CFR 50.92 EVALVATION Pursuant to 10 CFR 50.92 Georgia Power Company (GPC) has evaluated the proposed amendment and has determined that operation of the facility in accordance with the proposed amendment would not involve significant hazards considerations.

Backaround Amendment Number 32 and Amendment Number 12 to the Operatina Licenses for VEGP Vnits 1 and 2 included changes to the Technical Specifications that removed Figures 3.1-2 and 3.1-3 from the Technical Specifications and pl6ced them in the COLR. The Action statements for Specifications 3.1.2.2, 3.1.2.4, and 3.1.2.6 require that the shutdown margin meet the requirements of Figuro 3.1-2. Figure 3.1-2 provided the shutdown margin requirements for Mode 5. The figure has been incorporated it,o the COLR, however, the references to the figure made by these three Action statements were not revised in conjunction with the issuance of the license amendments. This proposed change provides the correct references, it does not result in any change in the requirements of the Action statements.

Bases section 3/4.2.2 and 3/4.2.3 refers to Figure 3.1-3, which has also been placed in the COLR. This proposed change provides the correct reference for Bases section 3/4.2.2 and 3/4.2.3.

. ..ici vs i s The shutdown margin requirements specified by the COLR for Mode 5 and the requirements of Figure 3.1-2 are the same. The only consequence of the proposed change to the Technical Specifications is to avoid the confusion that could occur if it became necessary to enter into'one of these Action stataments.

Since the COLR requirements are the same as those previously contained in Figure 3.1-2, this change will not alter any of the requirements of the Action statements. The rod bank insertion limits provided in the COLR are the same as those previously contained in Figure 3.1-3. The revision to Bases section 3/4.2.2 and 3/4.2.3 does not indicate any change in the bases for any Terbical Specification. it changes the reference from Figure 3.1-3 to the rod i,isertion limit specification which was revised by Amendment Number 32 and Amendment Number 12 to incorporate the COLR.

Conclusion Based on the above considerations, GPC has concluded the following concerning the requirements of 10 CFR 50.92.

1. The revisions to the Technical Specifications will not increase the probability or consequences of accidents previously oveluated in the FSAR because they do not alter any of the requirements of the Technical Specifications. The only change is in the location of the information.

2. The revisions to the Technical Specifications do not create the possibility of a new or different kind of accident other than those already evaluated in  ;

the FSAR because they do not create a change to the previous requirements. .

The changes do not involve any physical change to the plant or to the requirements for plant operation.

3. The proposed changes will not affect the margin of safety provided by the l Technical Specifications because they do not result'in any change to the  !

previous requirements, i Based upon the preceding discussion GPC has concluded that the proposed i revisions to the Technical Specifications do not involve a significant hazards i consideration as defined by 10 CFR 50.92 (c). j
