Subject:

Quad Cities Station Units 1 and 2 Prcposed Change to Facility Operating License Nos. DPR-29 and DPR-30 NRC Docket Nos. 50-754 and 50-265

Dear Mr. Denton:

Pursuant to 10 CFR 50.59, Commonwealth Edison Company hereby requests ~a change to-0p6 rating License Nos. DPR-29 and DPR-30, Appendix A, Technical Specifications. The purpose of this

-amendment is to modify the spent fuel storage racks to provide

! additional storage capability of spent fuel at Quad Cities Station.

The proposed change to the Quad Cities Technical Specifications is enclosed as Attachment I.

A report prepared for Commonwealth Edison by the Joseph Oat Corporation, " Licensing Report on High Density Spent Fuel Racks for

-Quad Cities ~ Project,"-Report TM-600, Rev. 1, dated 3/19/81, is also attachedLtu support the above change.

, . Quad Cities Units 1 and 2 have a combined licensed spent fuel storage capacity of 2920 spaces,:however-only a capacity of 22801 spaces is currently installed. Quad Cities has reinstalled racks which could bring'the capacity to 2400 spaces. The proposed change will' increase the capacity to-7570 storage spaces. High density fuel storage' racks containing Boraflex,'a neutron cbsorbing

material, will extend' fuel storage capability through about the year 2000, at which1 time-the ability to' accommodate'an emergency full core dischar'ge will be lost.

Without the. modification, Quad Cities will-not be-able to discharge a full core after December, 1981. The current moratorium on reprocessing'of spent fuel-necessitates this modification.

Pursuant to'10 CFR 50.59, Commonwealth Edison is conducting an extensive analysis of:the proposedLfuel storage pool.

-modification. The areas bcing examined 1from a safety standpoint-

include mechanical,. nuclear, structural, seismic,-thermo-hydraulic-land. radiochemical. This' examination-will demonstrate that all.

~

parameters 1ofLthe modified spentffuel pool maintain safety limits of -

theooriginal design'. -Some.of the'above analyses are=incluaed inLthe.

attached Joseph.0at report, and future revisions will include-results of thetremaining'~ analyses.

j . For normal and abnormal storage and handling of spent fuel in the storage racks, keff will not exceed 0.95. This analysis was performed using maximum fuel reactivities, a spent fuel pool water temperature'of 400F, eccentric positioning of the fuel in the proper storage location, and single fuel assemblies outside the storage racks. " Abnormal" refers to a single operator error.

In addition to these design parameter considerations, the i

health and safety of the public will not be jeopardized during i installation of the new racks or disposal of the existing racks.

The high density spent fuel storage racks will be installed in the water filled spent fuel pools'as the existing racks are removed.

Precautionary measures will be taken during the installation phase to ensure that new racks are not suspended above racks with spent fuel assemblies. Fuel will be shifted from storage locations in an orderly manner required to remove existing racks and install the new

racks.

This proposed change is scheduled to commence in the Summer of 1982 in order to ensure sufficient space for fuel shuffling.

4 This proposed Techncial Specification change (Attachment I)

.has been reviewed and approved by On-Site and Off-Site Review.

4 Pursuant to 10 CFR 170, Commonwealth Edison has determined that this proposed amendment is a~ combined Class III and Class I

' Amendment. As such, Commonwealth Edison has enclosed a fee remittance in the amount of $4,400.00 for this proposed amendment.

Three (3) signed originals and thirty-seven (37) copies of this letter and attachments are provided for your use.

Very truly yours,
