10 CFR 50.92 SIGNIFICANT HAZARDS DETERMINATION The proposed change does not involve a significant hazards consideration, because operation of Surry Uni ts 1 and 2 in accordance with the proposed amendment would not:

(1) Involve a significant increase in the probability or consequences of an accident previously evaluated. Increasing the Auxiliary Operator manning requirement will not alter plant design or system operation.

The proposed change would assure that the minimum number of operating personnel necessary to safely shutdown and maintain the unit in the event of a fire is available onsite. Therefore,. this change cannot increase the probability or consequences of an accident.

(2) Create the possibility of a new or different kind of accident from any accident previously evaluated. Si nee this proposal increases a previously specified manning requirement and further will not alter plant design or system operation, the possibility of a new or different kind of accident is not created by this change.

(3) Involve a significant reduction in a margin of safety. As noted above, the proposed change constitutes an additional limitation not presently included in the technical specifications by increasing the auxiliary operator manning requirement. In so doing, the margin of safety will be maintained with respect to Fire Protection.

Therefore, pursuant to 10 CFR 50.92, it has been determined that this change does not involve a significant hazards consideration.
