2) MAPLHCR limit curves have been added for CE fuel types 8P8DRB282 and '

BP80R8299 based on E and A Sheet No.14 to NEDO-24146A, Tables 4R and 45, respectively. Refer to Figure 3.5-1 Sheets 2 and 4 in Attachment 2.

( 3) MAPLHGR limits for fuel type " Barrier LTA" (Lead Test Assemblies) have l been extended out to 55,000 mwd /t planar average exposure based on E and l

A Sheet No. 14, Table 4H. Refer to Figure 3.5-1 Sheet 1 in Attachment 2.

ATTACHMENT 3 Evaluation of Significant Hazaros Consideration Oescription of Amenoment Request The proposed Technical Specification amendment includes the following (also see Attachment 1):

- Deletion of MAPLHCR limit curves for fuel types no longer in use

- Addition of MAPLHCR limit curves for new fuel types

- Extension of a MAPLHCR limit curve to higher fuel exposures.

The new and extended HAPLHCR limits are based on values provided in Erratta and Addenda Sheet No.14 to NE00-24156A, the Dresden and Quad Cities Loss of Coolant Accident Analysis.

! Dasis for Proposed No Significant Hazards Consideration Determination Commonwealth Edison has evaluated the proposed Technical Specifi-cation amendnent ono determined that it does not represent a s10nificant hazaros consideration. Based on the criteria for defining a significant hazards consideration established in 10 CFR 50.92(c), (;peration of Quad Cities Unit 1 in accordance with the proposed amendmen',s will not:

1) involve a significant increase in the probability or consequences of an accident previously evaluated because u) the amendments involve restrictions on the reactor power distribution during normal operation which of itself cannot initiate an accicont and therefore does not increase the probability of an accident and b) these restrictions on power distribution are based on a reunalysis

! or re-evaluation of accidents in uccordant.u with NRC approved l methods and are specifically provided to ensure that the l consequences of accidents (LOCA) remain within thu existing l accident criteria established for Quad C.tles.

( ,

l 2) create the possibility of a new or different kind of accident from any accident previously evaluated for the same ruason as 1)a above and i

N, '

.i. ,.

'N,

3) involve a significant reductiL1 in the margin of safety since the amendments are specifically intended to ensure that the 10 CFR 50.46 ECCS criteria continue to be protected during future operation.

In consideration of the above, Commonwealth Edison expects that NRC approval of these amendments should not be predicated on satisfactory resolution of public comments or intervention as provided for by 10 CFR 1

50.91(a)(4).
