ATTACHMENT NO SIGNIFICANT HAZARDS CONSIDERATION (Revised)

Nuclear Regulatory Commission License Amendment Request No. 2001-005 No Significant Hazards Consideration October 24, 2002 Page 2 Pursuant to 10 CFR 50.91, Duke Energy Corporation (Duke) has made the determination that this amendment request involves a No Significant Hazards Consideration by applying the standards established by the NRC regulations in 10 CFR 50.92. The specific responses to the criterion are discussed below:

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

Response: No.

The proposed change allows for one train of Low Pressure Injection to be inoperable for up to 7 days. The Low Pressure Injection system is not an initiator for any accident previously evaluated and the consequences of an event during the extended Completion Time are no more severe than the consequences of the same event during the current Completion Time. Therefore, the consequences of an event previously analyzed are not increased. Consequently, 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 accident previously evaluated?

Response: No.

The proposed change allows for one train of Low Pressure Injection to be inoperable for up to 7 days. The proposed change does not involve a physical alteration of the plant (no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. 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 the margin of safety?

Response: No.

The proposed change allows for one train of Low Pressure Injection to be inoperable for up to 7 days. An evaluation presented in Topical Report BAW-2295 and accepted by the NRC concluded that the extended Completion Time did not result in a significant reduction in the margin of safety. Therefore, the proposed change does not involve a significant reduction in the margin of safety.
