Subject:
Byron Station Units 1 and 2 Application for Amendment to Facility Operating License NPF-37,
. Appendix A, Technical Specifications NRC Docket Nos. 50-454 and 50-455 i
Dear Mr. Denton:
Pursuant to 10 CFR 50.90, commonwealth Edison proposes to amend Appendix A, Technical Specifications, of Facility Operating License NPF-37.
The proposed change, which involves an increase in the storage capacity of the spent fuel racks, is contained in Attachment A.
A licensing report regarding the proposed change is contained in Attachment B.
Chapter 8 of the licensing report describes an inservice surveillance program to verify the integrity of the neutron absorber material utilized in the high density fuel racks.
In addition to this program, neutron attenuation measurements will be made on the neutron absorber material during installation of the new racks in the spent fuel pool.
The proposed amendment has been reviewed and approved by both On-site and off-site review in accordance with Commonwealth Edison Company procedures.. We have reviewed this proposed amendment in accordance with 10 i
CFR 50.92(c) and determined that no significant hazards considerations exist.
- Our evaluation is documented in Attachment C.
t Prompt NRC review and approval of this proposed license amendment is requested. Sixty-four new fuel assemblies for Byron Unit 2 initial core load are-being stored in the current spent fuel racks. In the event Byron Unit.2 fuel load is delayed, these Unit 2 fuel assemblies will remain in the spent fuel racks. Storage of this Unit 2 fuel in the spent fuel racks has the potential of impacting the. installation schedule of the new spent fuel racks.
According to the present delivery schedule for the new spent fuel racks, installation of the new racks could proceed until about December 1, 1986. At that point, if Unit 2 fuel remained-stored'in the present spent fuel racks, further installation of the new racks would be suspended.
Approval of this proposed license amendment by December 1, 1986 would permit 3
movement of the Unit 2 new fuel into the new spent fuel racks.
Installation limitations on the remainder of the new spent fuel racks would thereby be
\\
O eliminated.

Mr. H. R. Denton September 3, 1986 Maintaining the present installation schedule of the new spent fuel racks ~is important to Commonwealth Edison because it will minimize the possi-bility of contaminating the present spent fuel racks. Unit 1 spent fuel will be placed in the spent fuel pool during the Unit I refueling outage which is presently scheduled for early 1987. Disposal of contaminated racks, as well as installing the new racks under wet conditions, would result in additional costs to Commonwealth Edison. For these reasons, NRC approval of this proposed amendment is requested by December 1, 1986.
Commonwealth Edison is notifying the State of Illinois of our application for this amendment by transmitting a copy of this letter and its attachments to the designated State Official.
In accordance with 10 CFR 170, a fee remittance in the amount of
$150.00 is enclosed.
Please direct any questions you may have concerning this matter to this office.
~Three (3) signed originals and thirty-seven (37) copies of this letter and attachments are provided for your use.
Very truly yours, Ka K. A. Ainger Nuclear Licensing Administrator la
