Nuclear Regulatory Commission A1TN: Document Control Desk Washington, D. C. 20555-0001 Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls Ladies and Gentlemen:

In accordance with the requirements of 10 CFR 50.90, Southern Nuclear Operating Company (SNC) proposes to revise Vogtle Electric Generating Plant (VEGP) Unit I and Unit 2 Technical Specifications (TS). The proposed change would revise TS Administrative Controls 5.2.2.g. TS 5.2.2.g would be revised to limit the requirement of the Shift Technical Advisor (STA) function to Modes 1-4 in accordance with NUREG 0737.

Enclosure I provides the basis for the proposed change. Pursuant to 10 CER 50.92, Enclosure 2 demonstrates that the proposed change does not involve a significant hazards consideration. Enclosure 3 contains a mark-up of the affected page from the current VEGP Technical Specifications. Enclosure 4 contains the typed version of the revised Technical Specifications page.

SNC requests approval of the proposed license amendment by March 2005, with the amendment being implemented within 60 days.

This letter contains no NRC commitments. If you have any questions, please advise.

Enclosure I Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls Basis for Proposed Change

Enclosure 1 Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls Bases for Proposed Change Proposed Change

  • Southern Nuclear Operating Company (SNC) proposes to revise the Vogtle Electric Generating Plant (VEGP) Unit I and Unit 2 Technical Specifications (TS). TS 5.2.2.g states: "An individual shall be assigned to each shift who provides technical support in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit." The following revision is proposed: "An individual shall be assigned who provides technical support in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit. This individual shall be available for duty when the plant is in Modes 1-4. At other times, this individual is not required."

Justification The objective of the Shift Technical Advisor (STA) function is to improve the quality of plant technical management and operation by providing additional on-shift expertise in the area of operational safety, thus reducing the probability of abnormal or emergency condition occurrences and mitigating the consequences of these conditions if they do occur. The STA's function is to provide engineering and accident assessment expertise to the shift supervisor in the event of abnormal or accident conditions.

Proper implementation of the STA requirement can provide significant assurance that engineering expertise is available and accident assessment is carried out for the immediate actions needed to be taken while an event is in progress.

On October 31, 1980, the NRC issued NUREG-0737, which incorporated into one document all Three Mile Island (TMI)-related items approved for implementation by the Commission at that time. Item I.A.1.1 of NUREG-0737 discussed the requirements for the Shift Technical Advisor. This section stated the following regarding the requirements for the STA function, in part: "Until these requirements for eliminating the STA position have been established, the staff continues to require that, in addition to the staffing requirements specified in its July 31, 1980 letter (as revised by Item I.A.1.3 of this enclosure), an STA be available for duty on each operating shift when a plant is being operated in Modes 1-4 for a PWR and Modes 1-3 for a BWR. At other times, an STA is not required to be on duty."

As indicated above, TS 5.2.2.g requires the STA function on each operating shift. With the clarification in Item I.A.1.1 of NUREG 0737, the STA function is only required in Modes 1-4 for a PWR. In addition, most transient accident analysis is limited to initiation in Modes 1-4. Of those not limited to Modes 1-4, the only significant ones are radiation waste and fuel handling accidents for which no operator actions are credited. Therefore, the STA function is notrequired in Modes 5 and 6. TS 5.2.2.g should be revised to require the STA function when the plant is in' Modes 1-4.

Enclosure 2 Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls 10 CFR 50.92 Significant Hazards Evaluation

Enclosure 2 Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls Significant Hazard Consideration Evaluation Proposed Changes Southern Nuclear Operating Company (SNC) proposes to revise the Vogtle Electric Generating Plant (VEGP) Unit I and Unit 2 Technical Specifications (TS). TS 5.2.2.g states: "An individual shall be assigned to each shift who provides technical support in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit." The following revision is proposed: "An individual shall be assigned who provides technical support in the areas of thermal hydraulics, reactor engineering, and plant analysis with regard to the safe operation of the unit. This individual shall be available for duty when the plant is in Modes 1-4. At other times, this individual is not required."

Evaluation

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

The proposed change to TS 5.2.2.g does not significantly increase the probability or consequences of an accident previously evaluated in the FSAR. This revision does not have any effect on the probability of any accident initiators. The consequences of accidents previously evaluated in the FSAR are not adversely affected by this proposed change because the STA is not credited for mitigation of any accidents. The proposed change which requires the STA function to be available while in Modes 1-4 is in accordance with the requirements of NUREG 0737, Item I.A.l.1.

Consequently, the probability or consequences of an accident previously evaluated are not significantly increased.

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

2. Does the proposed change create the possibility of a new or different kind of accident from any previously evaluated?

The proposed change to TS 5.2.2.g does not create the possibility of a new or different kind of accident from any previously evaluated. No new accident scenarios, failure mechanisms, or limiting single failures are introduced as a result of the proposed change. The proposed Technical Specifications change does not challenge the performance or integrity of any safety-related systems.

The proposed change to TS 5.2.2.g is in accordance with NUREG 0737.

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

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

The proposed change to TS 5.2.2.g will not reduce a margin of safety because it has no direct effect on any safety analyses assumptions. The STA function is to evaluate plant conditions and provide advice to the shift supervisor during plant transients and accidents. The proposed change limits the requirement for the STA function to Modes 1-4 in accordance with NUREG 0737. The STA function is not credited for the mitigation of any accidents previously evaluated.

Therefore, the proposed change does not involve a significant reduction in any margin of safety.

E2- 1

Enclosure 2 Vogtle Electric Generating Plant Request to Revise Technical Specifications Administrative Controls Significant Hazard Consideration Evaluation Conclusion Based on the preceding evaluation, Southern Nuclear has determined that the proposed change meets the requirements of 10 CFR 50.92(c) and does not involve a significant hazards consideration.

Environmental Evaluation Southern Nuclear has evaluated the proposed changes and determined that the change does not involve (i) a significant hazards consideration (ii) a significant change in the types or significant increase in the individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51 .22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), an environmental assessment of the proposed change is not required.
