I EVALUATION EQB S19EIFICANT HAZABDA QQFJJDERATION PROPOSED SPECIFICATION 5.0 DESIGN FEATURES The proposed changes provided in this amendment request are made in order to provide a more user friendly document. These changes have been reviewed by Commonwealth Edison and we believe that they do not present a Significant Hazards consideration. The basis for our determination is documented as follows:

RhSl3 EQ.B HQ SIGNIFICANT lihZARDS CpNSIDERATION Commonwealth Edison has evaluated this proposed amendment and determined that it involves no significant hazards consideration.

In accordance with the critoria of 10 CFR 50.92(c) a proposed amendment to an operating-license involves no sLgnificant hazards consideration if operation of the facility, in accordance with the proposed amendment, would nott J

1) Involve a significant-increase in the probability or consequences of an accident previously evaluated, because:

The proposed changes are administrative in nature and do not represent changes to the technical content of the present Technical Specifications. The relocation of present Figure 4.8-1, " Unrestricted Area Boundary," places this material in the Design Features Section of the Technical Specifications for consistency in location and presentation of material. Due to the nature of the proposed changes, they do not involve a significant increase in the probability or consequences of an accident previously evaluated.

2) Create the possibility of a new or different kind of accident from any previously evaluated because:

Due to the administrative nature of the proposed changes, they cannot create the possibility of a new or different kind of accident from any previously evaluated.

3) Involve a significant reduction in the margin of safety because:

The proposed changes maintain current Technical Specification requirements and the relocation of present Figure 4.8-1 to Section 5.0, is an administrative change. Therefore, the proposed changes do not involve a significant reduction in the margin of safety.

ENVIRONMENTAL hgER88 MENT EVALUATION  !

PROPOSED SPECIFICATION SECTION 5.0 1 i

DESIGN TEATURES Commonwealth Edison has evaluated the proposed amendment in accordance with the requirerents of 10 CFR 51.21 and has determined that the amendment meets the requirements for categorical exclusion as specified by 10 CFR 51.22(c)(9).

Commonwealth Edison has deter'.nined that the amendment involves no significant hazards consideration, there are no significant change in the types or significant increase in the amounts of any effluent that may be released offsite, and there is no significant increase in individual or cunulative occupational radiation exposure.

The proposed amendment does not modify the existing facility and does not involve any new operation of the plant.

As such, the proposed amendment does not involve any change in the type or significant increases in effluents, or increase individual or cumulative occupational radiation exposure. The proposed amendment to Section 5.0, " Design Features" contains only one change. In the existing Technical Specifications, the figure r; reficct the unrestricted area boundary is currently contained in Section 3.8/4.B. The proposed amendment removes the figure from Section 3.8/4.8 and relocates the figure to Section 5.0. As such, the proposed change is administrative in nature.

4 COMPARISON OF UNIT 1 AND UNIT 2 TECHNICAL DPECIFICATIONS FOR THE IDENTIFICATION OF TECHNICAL DIFFERENCES SECTION 5.0 DESIGN TEATURES Commonwealth Edison has conducted a comparison review of the Unit 1 and Unit 2 Techr.ical Specifications to identify any technical differences in support of combining the Technical Specifications into one document. The intent of the review was not to identify any differences in presentation style (e.g. table formats, use of capital letters, etc.), punctuation or spelling errors, but rather to identify areas which the Technical Specifications are technically or administratively different.

The review of Section-5.0, " Dosign Pontures" revealed the no technical or administrativo di"forences.
