u. S. Nuclear Regulatory Commission 3f0292 05 Page 4 StiOLLY EVALUATION OF REQUEST:

The requirements of 10 CFR 50.92 have been re'/iewed as they relate to the proposed chan e to the maximum boron concentration limit of the Borated Water Storage Tank BWST) and does not involve a significant hazards consideration. In support of this conclusion, the following analysis is provided:-

1. The proposed change will not significantly increase the probability or consequences of an accident previously evaluated because the reliability of the BWST is essentially unaffected by the change.

The consequences of the accidents remain bounded by the safety analyses.

2. The proposed change will not create the possibility of a new or different kind of accident from any accident previously evaluated tecause the function of the boron has not changed.
3. The proposed change will not involve a significant reduction in the margin of safety. The bnron increase to 3,000 ppm will increase the shutdown margin available post LOCA and maintain k,,, more negative.}}
