ATTACHMENT C SIGNIFICANT HAZARDS CONSIDERATION Commonwealth Edison has evaluated the proposed Technical Specifica-tion Amendment and determined that it does not represent a significant hazards consideration. Based on the criteria for defining a significant hazards consideration established in 10 CFR 50.92, operation of LaSalle County Station Units 1 and 2 in accordance with the proposed amendment will not:

Involve a significant increase in the probability or consequences of an accident previously evaluated, create the possibility of a new or different kind of accident previously evaluated or involve a significant reduction in the margin of safety because this change is administrative in nature ar.d does not effect any postulated accident. This change is in accordance with the requirements of 10 CFR 20.

Based on the preceding discussion, it is concluded that the proposed

-system change clearly falls within all acceptable criteria with respect to the system or component, the consequences of previously evaluated accidents will not be increased and the margin of safety will not be decreased.

Therefore.. based on the guidance provided in the Federal Register and the criteria established in 10 CFR 50.92(c), the proposed change does not constitute a significant hazards consideration.
